Earthquake and Seismic Gas Shutoff Valves Safety Tips

Earthquake and Seismic Gas Shutoff Valves Safety Tips

Earthquakes are a fact of life in King County. While most quakes are minor and cause little or no damage, the potential for a significant earthquake is always there. That’s why it’s so important to be prepared. Here are some tips on staying safe during an earthquake and adequately utilizing your earthquake and seismic gas shutoff valves.

During an Earthquake

If you’re inside when an earthquake hits, you should first drop to the ground and take cover under a sturdy piece of furniture. If there’s nothing nearby that you can use for cover, get down low and protect your head and neck with your hands and arms. Once you’re in a safe position, hold on until the shaking stops.

If you’re outside, move away from buildings, power lines, and anything else that could fall on you. Once you’re in a safe spot, drop to the ground and assume the same position as if you were inside. Again, hold on until the shaking stops.

After an Earthquake

Once the shaking has stopped, check yourself for injuries and check on others who may need help. If you smell gas or see sparks or fires, evacuate immediately and don’t turn any lights on or off or use anything electrical until you’re well away from the source of the danger. Only return home when authorities say it’s safe to do so. 

Shutting Off Your Gas

If your home has suffered damage during an earthquake, your gas line may have been ruptured. If you smell gas or see sparks or flames coming from any appliances that use gas (stoves, water heaters, etc.), shut off your gas immediately. 

To do this, locate your home’s main shutoff valve—usually near the meter—and turn it to the “off” position. Once the valve is turned off, don’t turn it back on yourself; only a qualified professional should do that.

Evergreen Seismic is Washington’s Trusted Earthquake Specialist

There is no way to predict when an earthquake will occur. That’s why it’s crucial to have a gas shutoff valve before an earthquake hits. In an earthquake, this will cut off your home’s gas supply, protecting you from potential explosions and flames.

With years of experience, Evergreen Seismic is a leading provider of earthquake and seismic gas shutoff valves in King County. We offer a wide range of products to suit all budgets and requirements, and our team of experts is always on hand to provide advice and support.

Seismic Retrofitting Specialists and the Dangers of Unsafe Buildings

Seismic Retrofitting Specialists and the Dangers of Unsafe Buildings

Do you live in an area that is at risk for earthquakes—like Seattle, WA? If so, your home may be at risk, too. Seismic retrofitting specialists can help make your home safer in the event of an earthquake by reinforcing its structure. Unfortunately, many homeowners are unaware of the dangers of seismically unsafe buildings. 

Dangers of Seismically Unsafe Buildings

There are many dangers associated with seismically unsafe buildings. First and foremost, these buildings are at a higher risk of collapsing during an earthquake. This can lead to serious injuries or even death for those inside the building. In addition, seismically unsafe buildings can cause damage to neighboring structures, and they can pose a danger to rescue personnel. 

Of course, the best way to protect against these dangers is to prevent them from happening in the first place. That’s where seismic retrofitting comes in—the process of reinforcing a building’s structure to make it better able to withstand the forces of an earthquake. This can be done by adding bracing or shear walls, installing foundation bolts, or increasing the size of floor and roof joists.

Why Seismic Retrofitting Specialists Are in Demand

The demand for seismic retrofitting specialists has increased significantly in recent years as more and more people have become aware of the dangers posed by unsafe buildings. Seismic retrofitting is not something that can be done by just anyone; it requires special training and skills.

How You Can Ensure Your Building Is Safe

If you’re responsible for a building, there are steps you can take to make sure it is safe in case of an earthquake. The first step is to have it inspected by a qualified engineer to determine whether it meets current seismic safety standards. 

If it doesn’t, retrofitting may be necessary. It’s important to note that retrofitting should only be done by qualified professionals; attempting to do it yourself could actually make the situation worse.

Evergreen Seismic Knows the Dangers of Unsafe Buildings

Earthquakes are a very real danger in many parts of the world, especially in Seattle, WA, and it’s crucial to be prepared in the event of one. Unfortunately, many buildings are not up to code and could collapse during an earthquake, putting lives at risk. Our seismic retrofitting specialists can strengthen your structure and make it much safer in an earthquake. Contact Evergreen Seismic today to learn more about our services and how we can help protect your property from the dangers of earthquakes.

Why Earthquake Retrofitting Specialists Can Change Your Life

Why Earthquake Retrofitting Specialists Can Change Your Life

As an Arlington, WA, resident, it’s crucial to be prepared for earthquakes. That’s why retrofitting your home is a great idea. Earthquake retrofitting specialists specialize in strengthening your home or building to make it more resistant to seismic activity. Here are three things you should know about earthquake retrofitting—they could change your life in an emergency.

The Type of Soil Your Home is Built on Makes a Difference

When it comes to earthquake retrofitting, the type of soil your home is built on makes a big difference. If your home is built on soft soil, it will be more likely to experience damage during an earthquake. 

That’s because soft soils amplify the shaking that occurs during an earthquake. On the other hand, if your home is built on hard rock, it will be less likely to experience damage because hard rock absorbs the shock of an earthquake better than soft soil.

The Age of Your Home Matters, Too

Another factor contributing to the need for earthquake retrofitting is the age of your home. Older homes are more likely to experience damage during an earthquake because they weren’t built with modern building codes in mind. 

Building codes have become more stringent as our understanding of earthquakes and their effects has improved. Therefore, homes built before these newer codes were put into place are more likely at risk for damage during an earthquake.

When Should You Retrofit Your Home?

Ideally, it would help to retrofit your home before an earthquake hits. However, if you haven’t had a chance to do so yet, it’s still better to retrofit than not at all. After an earthquake has already caused damage to your home, it can be much more difficult and expensive to make repairs.

What You Need to Know About Seismic Fastening

What You Need to Know About Seismic Fastening

Most of us don’t consider seismic fastening until a significant earthquake hits. But if you live in an area prone to earthquakes like Seattle, WA, it’s essential to be aware of your earthquake and seismic fastening options. In this article, we’ll cover everything you need to know about seismic fastening, from the different types of systems available to the benefits of retrofitting your home.

Types of Seismic Fastening Systems

Three types of seismic fastening systems exist – mechanical fasteners, adhesive anchors, and poured-in-place anchors. 

Mechanical fasteners are the most commonly used type of seismic fastener. They work by creating a friction fit between the wall and the framing. The most common type of mechanical fastener is the anchor bolt, which is embedded in the concrete foundation and then attached to the wood framing with a nut and Washer. 

Adhesive anchors are another seismic fastener that can be used in new construction and retrofit applications. Adhesive anchors work by bonding the wall to the framing with a strong epoxy adhesive. The most common type of adhesive anchor is the plate anchor, which consists of a metal plate attached to the wall with an adhesive. 

Poured-in-place anchors are another seismic fastener that can be used in new construction and retrofit applications. Poured-in-place anchors work by bonding the wall to the framing with a strong epoxy adhesive. The most common type of poured-in-place anchor is the expansion anchor, consisting of a metal sleeve filled with concrete and then expanded with a hydraulic ram. 

Seismic Fastening Options for Your Home

Earthquakes can happen without warning and can cause severe damage to your home or business. Seismic fastening is an essential step in earthquake-proofing your building. 

Evergreen Seismic has various seismic fastening options to suit your needs. We carry products for wood-frame construction, masonry walls, and concrete foundations. We also offer a variety of fasteners, including bolts, nails, and screws. Our team of experts in Seattle, WA, will help you choose the best earthquake and seismic fastening for your property and ensure that they are installed correctly. With Evergreen Seismic, you can rest assured that your building is safe from earthquakes.

Prevent Gas Explosion and Fires With Seismic Shut-Off Valves

Prevent Gas Explosion and Fires With Seismic Shut-Off Valves

Earthquake and seismic gas shut-off valves are an essential safety measure for any home or business near Lake Stevens that uses natural gas. These valves automatically close the gas flow in the event of an earthquake, preventing potentially devastating explosions and fires.

While many newer buildings require seismic shut-off valves, older buildings may not have them installed. Home and business owners can protect their property by retrofitting their gas lines with these life-saving devices. Seismic shut-off valves are a relatively simple and inexpensive addition that could make all the difference in an emergency.

What Is a Seismic Shut-Off Valve and What Does It Do

A seismic shut-off valve is a type of valve that is used to automatically shut off the flow of gas or water in the event of an earthquake. These valves are typically installed in areas that are prone to seismic activity. Seismic shut-off valves are designed to protect against damage to pipelines and other infrastructure that can be caused by an earthquake.

The valves are triggered by sensors that detect the ground shaking and can close within a few seconds. This helps to prevent gas leaks and water damage in the event of an earthquake. Seismic shut-off valves are an essential part of protecting against damage during an earthquake, and they are required by law in some areas.

Why Are They Important For Gas Explosions and Fires

Seismic shut-off valves are essential for gas explosions and fires because they shut off the gas flow automatically when they sense sudden movement or vibration. This prevents gas from being able to build up and explode or catch fire.

In areas like Seattle, where earthquakes are common, seismic shut-off valves can be a lifesaving measure. They should be used in addition to other safety measures, such as having a gas shut-off valve in your home that you can manually turn off in the event of an earthquake.

Seismic shut-off valves are also important in industrial settings with a fire or explosion risk. For example, if a pipeline is damaged, the automatic shut-off valve will prevent any further leakage of gas. This can help contain the damage and prevent a more significant fire or explosion.

Trust the Experts in Seismic Safety

Evergreen Seismic is a leading provider of earthquake and seismic gas shut-off valves near Lake Stevens, and we’re committed to helping our customers be prepared for the worst. Our valves are backed by a team of qualified installation and support staff, and we offer a variety of models to meet the needs of any home or business.

Increase Your Home Value With Seismic Retrofitting Specialists

Increase Your Home Value With Seismic Retrofitting Specialists

Seismic retrofitting strengthens a building or structure to withstand earthquakes in Seattle better. While this often includes adding additional support to the foundation or walls, it can also involve changing how the building is braced against the ground. Seismic retrofitting is a specialized field, and structural engineers specializing in this area are known as seismic retrofitting specialists

These specialists have the knowledge and experience to assess a building’s earthquake risk and recommend the best ways to reduce that risk. In many cases, they also can oversee the implementation of their recommendations. 

How Seismic Retrofitting Can Save Your Home

Seismic retrofitting can also involve changes to the foundation or other building parts that are not directly related to the strength or stiffness of the structure. Seismic retrofitting is often used on buildings not designed to withstand earthquakes or older buildings whose structural elements have deteriorated over time.

Retrofitting can also increase the value of your home, as it will be more likely to withstand damage in the event of an earthquake. And finally, if you are planning on selling your home, potential buyers will often be more interested in a home that has been retrofitted. 

Seismic Retrofitting is the Best Investment You’ll Make

Seismic Retrofitting is the best way to protect your property during an earthquake and one of the best investments you can make. A seismically retrofitted building will be worth more after an earthquake than a non-retrofitted building and can withstand future earthquakes with minimal damage. 

Earthquakes are a fact of life in Seattle, and retrofitting your property is the best way to protect it from damage. Evergreen Seismic is the best seismic retrofitting specialist in Washington and has retrofitted thousands of buildings throughout the state. If you are interested in seismically retrofitting your property, contact Evergreen Seismic today for a free consultation.

You Don’t Need to be an Engineer to Feel Safe: You Need an Earthquake Retrofitting Specialist

You Don't Need to be an Engineer to Feel Safe: You Need an Earthquake Retrofitting Specialist

While the term “seismic” may conjure images of devastation and destruction, the reality is that most earthquakes cause significant damage to buildings and other structures. In areas where earthquakes are relatively common, like Everett, WA, it’s vital to take steps to minimize the risk of damage. One way to do this is? Technology from trusted earthquake retrofitting specialists strengthens the foundation of a building to withstand the forces of an earthquake better.

Protect Your Building

Seismic foundation retrofitting is not a new concept; it has been used for centuries in seismically active regions worldwide. For example, many medieval churches in Italy were retrofitted with metal braces to reinforce their foundations. Modern technology has made it possible to strengthen foundations with various materials, including carbon fiber, steel, and concrete.

While seismic foundation retrofitting is not required by law in most jurisdictions, it is strongly recommended for any building located in an area with a high risk of earthquake activity. In fact, many insurers will not provide coverage for buildings that have not been retrofitted. The cost of retrofitting can vary depending on the size and type of building, but it is typically a small fraction compared to the massive damage that is a daily risk from seismic activity. 

Strengthen Your Foundation With Our Technology

Seismic retrofitting can be applied to new and old buildings and structures of all types, including wood-frame, masonry, non-ductile concrete, and steel-frame buildings. By increasing the strength, stiffness, and ductility of a building or structure, seismic retrofitting can help to reduce damage during an earthquake and improve the likelihood of it remaining standing after the shaking has ended. 

Our earthquake retrofitting specialists in Everett provide cost-effective means of retrofitting existing buildings and structures. With our system, buildings can be quickly and easily strengthened without the need for prohibitively expensive demolition and reconstruction. This technology delivered from Evergreen Seismic can help protect lives and property while also significantly reducing long-term costs.

Don’t Be the Last to Seismic Retrofit your Foundation

Don't Be the Last to Seismic Retrofit your Foundation

As our world continues to urbanize at an unprecedented pace, the number of people living in seismically active areas is rising. This means that the chance of experiencing a devastating earthquake is also increasing. However, some measures can be taken to help protect against earthquake damage — such as retrofitting buildings to improve their seismic performance. Seismic foundation retrofitting in Seattle is the process of strengthening a structure to have a better chance of withstanding the shaking caused by an earthquake. 

The goal is to reduce the damage that an earthquake can cause and ensure that the building remains functional after the event. Many different techniques can be used for seismic retrofitting, and the most appropriate approach will depend on the type of building and its existing condition. 

Seismic Foundation Retrofitting: Will You Be Ready?

Standard seismic retrofit methods include adding bracing or shear walls, installing base isolation systems, and retrofitting column capital beams. When done correctly, seismic retrofitting can significantly reduce the risk of damage during an earthquake. Retrofitting is often required by building codes in areas of high seismic risk and is also usually recommended for older buildings that were not designed to withstand earthquakes.

In many cases, retrofitting can add years to the life of a building and help to protect the safety of occupants during an earthquake.

We Can Fix Your Foundation Without Breaking the Bank

As our world becomes increasingly vulnerable to seismic activity, it is crucial to be prepared. Seismic foundation retrofitting is one way to help protect against earthquake damage. It should be seriously considered by those who live in seismically active areas — especially in Seattle, WA. Evergreen Seismic can assess your property and fill you in on how you can keep your property — and, more importantly, your family — safe from earthquake damage. Call us at (206) 984-2580.

Seismic Foundation Retrofitting Can Save Your Home

Seismic Foundation Retrofitting Can Save Your Home

Seismic foundation retrofitting near Lynwood is one of the most important things you can do to protect your home from an earthquake. It can mean the difference between your home surviving a quake unscathed or sustaining serious damage that could cost you thousands of dollars to repair.

If you live in an area that is at risk for earthquakes, it is important to have your home evaluated by a qualified engineer to determine if it needs to be retrofitted. Many homes built before the mid-1970s were not constructed with consideration to earthquakes and are more vulnerable to damage.

How Do You Retrofit a Home?

There are many different ways to retrofit a home, but the most common and effective method is installing seismic bracing around the house’s perimeter. This will help to stabilize the house and prevent it from collapsing in an earthquake.

While seismic foundation retrofitting is not required by law, it is strongly recommended for homes in earthquake-prone areas. It is also a good idea to retrofit your home if you plan on selling it, as this will increase its value and make it more attractive to potential buyers.

Does Your Home Need Seismic Retrofitting?

There are many variables to consider when determining if a building needs to be retrofitted, such as the age and condition of the structure, the type of soil it is built on, and the severity of seismic activity in the area. 

Our team of experts at Evergreen Seismic can help you assess these factors and determine if your home or business would benefit from seismic foundation retrofitting near Lynwood. We will also work with you to develop a custom plan that meets your specific needs and budget. Contact us today at (206) 984-2580 to learn more about how we can help you protect your property from earthquakes.

We Love Our Customers!

They did a wonderful job on the seismic retrofitting. Our 1926 house is noticeably more stable. The workers were very pleasant to have in our home, and they cleaned up shockingly well when they were done. If we could hire them for the rest of our home improvement job we would.


It’s a matter of time, experts say, before the Northwest shudders under another massive tectonic plate earthquake or the Puget Sound region succumbs to a big quake from one of its faults. Wood frame homes generally survive the earth shaking. But there’s a risk of them sliding off the foundation. Split-level homes also may crumble along the pony wall, sometimes called a cripple wall, that supports the upper level. Quake risks were not that well known when my home was built in Bothell in 1975. In the summer of 2022, Evergreen Seismic upgraded the house with a retrofit. This included installing anchor bolts and hold-downs into the foundation and bracing the walls in places with ¾-inch CDX plywood. Owner Matt Robinson and his crew worked in a tight crawlspace. They also removed some outside siding to brace the pony wall, upgrading the insulation before replacing the siding. Matt handled all the required engineering plans, permits and inspections. Matt showed he is skilled in retrofitting. He communicated clearly about scope of the work and scheduling. The site was cleaned after each day and neatly finished at the conclusion. The retrofit improved the safety of my home. I have documentation that I believe adds to its value. Of various people we’ve had in our home from time to time for repairs or remodeling, Matt Robinson is one of the best. I recommend Evergreen Seismic for its quality of work and service. Doug in Bothell


If you need to earthquake your home for seismic activity, then you can definitely trust these guys. Matt and his team at Evergreen Seismic are very knowledgeable and do a great job.


I loved Evergreen Seismic so much that I hardly know where to start this review. I got three bids to retrofit our 1962 home, which has a finished walkout basement and required structural engineering. All three companies were very professional and gave me comparable recommendations. Here’s why I’m so happy that I went with Matt: Quality and attention to detail: Notably, a respected competitor described Matt as “the best retrofitter I know.” During the bid process, Matt answered my extensive questions with sound, thorough information. On site, he was happy to show me the in-progress guts of the work, explaining the rationale and placement of all the hardware, additional framing, and shear panels. He also pointed out places where people sometimes cut corners and educated me on how to recognize correct, up-to-code work. Matt and Nick used high-quality materials, high-quality tools, and every element they added to our home was carefully and precisely placed. Their work passed all inspections without a hitch. Matt even paid thoughtful attention to aesthetic details, like staggering their cuts into our siding for a pleasing end result, and purchasing a color of caulk that would blend into our paint. In all matters of quality, Matt ran a tight ship. I feel safe and secure in our home, having witnessed his expertise and skill. Professionalism: Others have said it, and I’ll say it again: Matt is the consummate professional. He was easy to communicate with and responded quickly. He set clear expectations for any minor distress the siding of the house might incur during the project. He cheerfully dealt with tight spaces and a maddening tangle of defunct cables attached to the side of the house. He and Nick kept a tidy jobsite, cleaning up beautifully at the end of each day and truly leaving the interior cleaner than they found it at the end of the job. They appeared to even be packing out tiny pieces of trash like paper towels from washing their hands, rather than using the trash cans I placed out for them. Matt had to cut an old landline cable that we hadn’t planned to use, and he pointed it out right away and offered to pay to have it reconnected - a high-integrity move. Finally, he spoke very highly of his competitors without exception, which says a lot. Kindness and care: Matt is just a wonderful human to be around. He’s easygoing, straightforward, considerate, thoughtful, warm, and generous with his time. When I met Matt in the fall, I was experiencing a period of high anxiety, and I came to him with a long list of bothersome questions as I was deciding who to hire. Even though he was busy, he went far out of his way to write detailed answers, send me safety data sheets, and chat on the phone with me multiple times. Some of my questions and worries were probably ridiculous, but he treated them as if they were completely reasonable and even welcome. He never made me feel like an annoyance, and his willingness to meet me where I was at, with so much empathy and humanity, meant a lot. Oh - and he and Nick treated my five-year-old as a person worthy of as much attention and respect as an adult, which is rare! With all of that put together, we were so happy we went with Matt and honestly feel kind of bummed that we probably won’t ever get to hire him for anything else. A few final details: Matt’s bid was in the middle of the three we received, but it was within $40 of its closest neighbor, so basically identical. Contracts and payment were all quick and easy. And for anyone exercising extra caution during the pandemic, Evergreen Seismic was extremely covid-conscious. The team was fully-vaccinated and wore high-quality masks for the entire duration of the job. I don’t even know what their faces look like. Even though they were working outdoors in the fresh air with no one else around, they always had a mask around their neck to be pulled up within a moment’s notice when I popped over to greet them. A+!


Evergreen Seismic recently completed an earthquake retrofit on our home. We chose the company in part because of great online reviews and we were not disappointed. Matt clearly explained the entire process and patiently responded to all of our questions. The work went smoothly and efficiently, was completed ahead of schedule, and the daily cleanup was amazing. Most importantly (for us anyway), the person who sold us on the job (Matt) was also part of the working crew. I wholeheartedly recommend Evergreen Seismic for earthquake retrofitting. From start to finish, this was by far the smoothest construction job we have experienced during the twenty years that we have lived in our home.


We used Evergreen Seismic to do an earthquake retrofit on our 1979 build home in Kent, WA based upon great customer reviews. We were not disappointed! Matt and his crew were very professional and showed up as promised. We were promptly informed when on one occasion they were a bit late due to traffic congestion. The work was performed to our satisfaction. The daily cleanup was impeccable. Matt was able to answer all questions that the inspector asked to his satisfaction. The Company actually went over and above what the structural analysis indicated was needed (additional bracing was installed). The majority of the retrofit was done on the exterior of the house in pouring rain! However, to our amazement, this did not in any way slow down the crew! A truly professional Company. We can recommend Evergreen Seismic without any hesitation.


Exceptional service from Evergreen Seismic. I met Matt at an info session on seismic retrofitting hosted by the city of Seattle. It took me a year or so to reach out to him. I was impressed form the start. Matt was more than willing to coach me on doing the project myself, if I wanted to take it on. But in given the complexity of our project, I preferred to hire Matt and his crew. They did a great job, and even did some prep that I was supposed to do but couldn't because of a recent back injury. Very straightforward, informative, and considerate service. I'd hire Matt again without hesitation.


Matt did the seismic retrofit of our single-family residence back in January when we were finishing our basement. I cannot speak highly enough of him and Evergreen Seismic. Matt has undoubtedly been one of the best contractors we've worked with. He's an excellent communicator and really goes above and beyond on all fronts. He does what he says he's going to do, when he says he's going to do it, and finishes when he says he's going to finish, all at an extremely competitive price. He's knowledgeable of seismic retrofitting and has a very streamlined process nailed down. If you are thinking of doing a seismic retrofit, Evergreen Seismic is DEFINITELY the way to go!


Matt and crew performed a larger earthquake retrofit project for us that took the entire month of May. The project involved building out a new foundation /wall to connect between posts on the back half of the house to prevent lateral shear, as well as all of the hardware to attach the rest of the house to the foundation. We had a similar experience to the other positive reviews here - Matt has a truly exceptional work ethic and clearly takes a lot of pride in his work, and expects the same of his crew. Matt is very knowledgeable and was more than happy to answer all of our questions. Communication and timeliness were well above par from start to finish, and they were also competitive on pricing (slightly lower than other bids of the same scope). They were a pleasure to have around the house (actually, outside the house, because they were able to take off the siding and do the work from the outside, while a competing bidder was planning on going inside to remove drywall), and were always available for questions. A nice extra touch was that they installed new insulation in 2 of our walls which was not part of the fixed price bid (another reason we went with Evergreen - no risk of cost overrun). Thanks Matt and crew, truly appreciate your work!


Evergreen Seismic did an outstanding job on my retrofit. They fit my project in right away, provided a clear and thorough bid and scope of work, and completed the project on time. Absolutely a pleasure working with them. Highly recommended!
