Protecting Seattle’s Historic Homes from Earthquakes with Seismic Retrofitting

Protecting Seattle’s Historic Homes from Earthquakes with Seismic Retrofitting

Seattle is no stranger to earthquakes, and its historic homes are particularly vulnerable to seismic activity. Fortunately, seismic foundation retrofitting can help protect these structures from the worst of a major quake. This blog post will discuss the basics of seismic retrofitting and how it can help preserve the city’s history. 

What is Seismic Foundation Retrofitting? 

Seismic foundation retrofitting is a process in which structural elements are added or reinforced to make a building more resistant to shaking caused by an earthquake. This type of retrofitting typically involves reinforcing the foundation or walls of a structure and strengthening any parts of the building that may be weak or prone to collapse. It is important to note that not all buildings require seismic retrofitting; however, those located in areas prone to earthquakes should consider it. 

The Benefits for Historic Homes 

Seismic retrofitting has many benefits for historic homes in Seattle. Since these buildings were constructed before modern building codes, they may not have been designed with earthquakes in mind. As such, they are more likely to suffer significant damage during an earthquake than newer structures. 

By strengthening them with seismic retrofits, these homes can better withstand major quakes and remain standing even after the worst has passed. Additionally, seismic retrofits can help reduce damage caused by minor tremors regularly occurring in Seattle and other quake-prone areas. 

In addition to providing physical protection against earthquakes, seismic retrofits also offer financial benefits for homeowners in Seattle’s historic neighborhoods. 

Since these buildings have been around for decades, their value has increased significantly over time—but this value could be lost if they were destroyed during an earthquake and had to be replaced with new construction. By protecting them with seismic retrofits, homeowners can ensure that their investments remain safe from potential disasters and continue to appreciate over time.

Earthquake and Seismic Fastening For HVAC Ductwork

Earthquake and Seismic Fastening For HVAC Ductwork

If you live in an area prone to earthquakes like Kenmore, it’s crucial to ensure your HVAC system is securely fastened in place. Not only can adequately installed and secured HVAC systems help protect the safety of your home during an earthquake, but they can also reduce damage to the system itself. So what’s involved in earthquake and seismic fastening for HVAC ductwork? Let’s take a look.

Earthquake and Seismic Fastening For HVAC: The Basics

Earthquake and seismic fastening involve securely attaching HVAC systems to walls or ceilings using a variety of specialized hardware.

This helps keep the system in place if there is an earthquake, reducing the risk of the system becoming damaged or dislodged. It also helps keep the system from becoming a hazard—if it falls during an earthquake, it could cause injury or further damage.

The type of hardware used for seismic fastening depends on the material being attached (e.g., wood, drywall, concrete) and the weight of the object being attached.

For example, heavier objects such as air conditioning units may require more secure installations than lighter objects such as vents or ductwork. In most cases, it’s best to consult a professional to determine which type of hardware will best suit your particular situation.

Why Should I Secure My HVAC System?

In addition to helping protect your home against earthquakes and other natural disasters, properly installed and secured HVAC systems can also help reduce energy costs.

If a system isn’t firmly attached, air leaks can occur around loose joints or gaps, leading to higher energy bills due to lost air—air that needs to be replaced by running fans longer than necessary or running extra cycles on your furnace or air conditioner.

The cost savings from having a properly secured system are significant enough that many homeowners install seismic-rated anchors even if they don’t live in areas known for earthquakes or other natural disasters.

Newest Advances in Earthquake and Seismic Fastening For Your Home or Business

Newest Advances in Earthquake and Seismic Fastening For Your Home or Business

Earthquakes can tremendously damage Seattle homes and businesses while also causing life-threatening situations. That’s why homeowners, business owners, and contractors must stay updated on the newest advances in earthquake and seismic fastening systems. Let’s look at some of the latest advances available for improving seismic protection in your home or business. 

Earthquake Resistant Bolts 

Installing earthquake-resistant bolts is one of the most widely used methods for strengthening a structure during an earthquake. These bolts are designed to absorb shocks from seismic waves and keep your building intact. 

They are made up of two parts—the head, a thick metal plate attached to the wall, and the body, which consists of two plates connected with large nuts and washers. Earthquake-resistant bolts come in various sizes and can be customized to fit any application. 

Seismic Isolation Systems 

Seismic isolation systems are another way of providing additional protection against earthquakes. These systems work by isolating a structure from ground movements during an earthquake. 

This isolation reduces the amount of energy transmitted through the structure during a seismic event, thus reducing damage and potential loss of life due to the collapse or destruction of the building’s foundation system. Seismic isolation systems can be installed either before or after construction has begun on a building, depending on its location and design needs.

Base Isolation System 

The base isolation system is one type of seismic isolation system that has gained popularity due to its ability to provide more effective protection against earthquakes than other methods, such as structural braces or friction pendulums. 

The base isolation system works by separating a structure’s main support columns from its foundations using flexible bearings that allow vertical movement but restrict horizontal movement between them during an earthquake.

This reduces strain on both the foundation and main support columns while still allowing them to move independently during an earthquake without compromising structural integrity or stability. 

Earthquake and seismic fastening systems are essential for protecting your Seattle home or business from potential damage caused by seismic activity. By staying informed about the latest technological advances, you can ensure that your home or business will be protected against even the strongest earthquakes imaginable! Contact Evergreen Seismic today to learn how you can stay protected!

We Love Our Customers!

We would definitely hire this company again. They had good communication; were prompt; respectful of our property; and completed the work in less time than expected. In general, they did a great job.


Evergreen Seismic came up in a Google search when I was questioning whether my earthquake insurance was really necessary, so I called and owner Matt came out for a free inspection. It turned out that our house did have some risk factors and Matt explained what he recommended and how they would do the job. After some research, I decided to proceed. They just finished after less than a week and Matt and his crew were thoroughly professional and friendly. I especially appreciated Matt's willingness to take extra time explaining things and he even offered some free advice on a couple of unrelated areas where some foundation repair was needed. A residential seismic retrofit isn't cheap and like any insurance, you hope you won't need it. I'm happy with the quality of the work performed and the price. I would recommend Matt and Evergreen Seismic to anyone thinking about making their home more earthquake tolerant.


We worked with Evergreen Seismic in the Summer of 2023 to retrofit our Seattle home. From the very first meeting, we knew that Matt was the right person to trust this project to. He is very knowledgeable and competent, and our communication was always transparent and smooth. Evergreen Seismic coordinated the process of getting the proper permit from the city (which took some time since we were using the standard set of plans) and provided us with all the documentation. When the time came for the retrofit itself, it was performed quickly and efficiently, in just one day for our one-story, 3-br. home. The city inspector was happy with the job as well! We confidently recommend Evergreen Seismic and Matt to anyone planning a seismic retrofit work in the Seattle area.


Evergreen Seismic was amazing to work with. Matt was quick to respond to our initial query, and took the time to walk us through the process and answer questions when he came out to look at the house. His bid was very clear and thorough. He's also a great communicator and made the whole process extremely smooth once we decided to go forward. We really appreciated that nothing felt rushed or unexpected. The crew here doing the work was considerate, patient with any questions we had, and kept us updated every day about what was going on. They did a really great job retrofitting our basement and crawl space and took care of some necessary repairs as well. We were lucky enough to have Evergreen recommended to us, so passing on the recommendation now! We would hire them again with zero reservations.


Evergreen Seismic and Matt were such blessings to us during our seismic retrofit on a Bellevue home we just bought! Matt and his crew, Phil and Nick, were all equally tremendous and beyond helpful to us and my inlaws! We were hell bent on seismically retrofitting by removing drywall interiorally vs sidings exteriorally. And Matt was accommodating to our request. As a hedge though, we knew we wanted a contractor who knows how to retrofit by both methods should a need arises during the retrofit peocess! And Matt fits the bill with his extensive knowledge and years working in earthquake retrofitting. They say never open up drywall if you don't want to find out what deep dark secrets lie underneath. And boy, did we unearthed a structurally problematic framing job on most all the studs holding up an exterior wall of the house, which threw my husband and I in a loop thinking of the scope creep. But Matt stuck with us, helped to sister in all new 2x4s on the compromised studs, and best yet didnt charge us an arm and a leg to fix the framing issue because he truly cares about doing the best job at the most economical rate. The framing job along with the seismic retrofit all easily passed various round of inspections. What started as out as contractor/client relationship became friendship based on what transpired with our house framing issue. We can only hope to find contractors as knowledgeable and honest as Matt and crew!


I would hire Matt again in a heartbeat. Not only do he and his crew perform good work (in my case, seismic retrofit) at a fair price, he combines his core competencies with great people skills and clear, timely, winsome communication. I am especially grateful to Matt because he was ever so patient with me when I suffered long COVID a few weeks after signing the contract, prompting me to delay the project a few months while I recovered. Matt turned what I expected to be a stressful experience into a very good experience. I encourage anyone considering a seismic retrofit to invite Matt to visit you and give you an estimate. I expect that you, too, will be highly satisfied with the result.


Matt did a fantastic job on the earthquake retrofit for our home. Our garage had never been so clean as it was after he was done with his work. Matt had the utmost professionalism through every step of the project. The contract clearly explained everything he was going to do, and he completed every step exactly as described. He thoroughly answered each of my questions during his initial visit in a way where he not only answered the question I asked, but gave background information to educate me on the topic of seismic retrofit. It's great to have the peace of mind that not only is my home now better able to withstand the "big one" that will eventually come to the PNW, but also that the work was done by a great company.


Matt is knowledgeable and competent, and he communicates clearly before and during the job. He made sure that we knew what our options were, and that we understood them. Matt is a friendly, likable person and obviously cares about doing a professional job. He wants his customers to be happy. It was soon clear that we could count on Matt and his team to show up on time and also to clean the site each day before they left. They worked all day each day until the project was finished. I would certainly recommend Evergreen Seismic to anyone who wishes to retrofit their home. I have confidence now that my 1901 home is in much better shape to withstand a significant earthquake without coming off the foundation.


Matt came out to see if our house needs a retrofit and I was absolutely blown away by his honesty, knowledge and professionalism. He advised against retrofitting our house due to the newer age of the home but did provide me with a tonne of useful information that I did not come across during my research and while speaking with other retrofit companies.


I was extremely pleased with the seismic retrofitting job Matt and his team completed for me. The entire experience was seamless. Matt was extremely informative during the bidding process and everything was completed on time and to a high standard. The work site was cleaned everyday and work plans and schedules were clearly communicated. It's obvious that Matt and his team really care about performing quality work. To echo another review, if I could hire them for all my home renovations, I would.
