Seismic Strengthening in Washington

Reinforce Your Home or Business Against Earthquakes

Earthquakes and tremors can weaken your foundation over time. Our seismic strengthening solutions provide long-term structural reinforcement to keep your property safe when the ground shakes.

Reinforcing Homes and Businesses Against Earthquakes

What Is Seismic Strengthening?

Western Washington experiences frequent seismic activity due to its location along major fault lines. Even small tremors can weaken a building’s structure over time, and larger earthquakes can cause catastrophic damage. Seismic strengthening reinforces foundations, walls, and columns to better withstand lateral and vertical ground forces.

Our team uses advanced structural repair systems — including seismic anchors, carbon fiber reinforcement, and foundation bracing — to permanently strengthen homes and commercial buildings. By reinforcing vulnerable areas, we help protect your investment and give you peace of mind when the ground shakes.

Common Signs You May Need Seismic Strengthening:

Cracks appearing after seismic events

Older homes built without seismic reinforcement

Chimneys, retaining walls, or porches pulling away from structures

Homes located in high-risk seismic zones (like Western Washington)

Visible signs of structural stress such as bowed or leaning walls

Reinforcing Structures to Withstand Earthquakes

  3. Structural Reinforcement – Install carbon fiber straps, steel brackets, and seismic anchors to strengthen walls and footings.
  4. Foundation Tie-Ins – Secure the home or building to its foundation to prevent shifting during quakes.
  5. Final Testing & Verification – Confirm reinforcements meet or exceed seismic standards.

Answers About Earthquake-Ready Homes & Buildings

Seismic Strengthening FAQs

What is seismic strengthening?

It’s the process of reinforcing homes or buildings with anchors, braces, tiebacks, and other systems so they can better withstand earthquakes.

Why is it important in Western Washington?

Our region sits on multiple fault lines and experiences hundreds of small seismic events every year. Without reinforcement, even minor tremors weaken structures over time.

What homes benefit most from seismic upgrades?

Older homes, homes with unreinforced masonry, or those built on steep slopes are at the highest risk and benefit the most from strengthening.

Does seismic strengthening ruin the appearance of my home?

No. Most upgrades are low-profile and installed in crawl spaces, basements, or behind walls where they aren’t visible.

How disruptive is the process?

Seismic strengthening times vary based on the size and scope of the project. For example, larger commercial retrofits may take longer while smaller, less complex projects may take less time.

How long do seismic upgrades last?

Properly installed reinforcements provide decades of protection and bring your home up to modern safety standards.

Will seismic strengthening lower insurance costs?

In some cases, yes. Many insurers offer discounts for earthquake-ready homes.

Is seismic strengthening only necessary for older buildings?

Seismic strengthening is most commonly recommended for older buildings. However, newer structures can benefit from an assessment.

Update 4/12/26 The company reached out to us, came to our home and made a plan to properly lift our house. The work was done in a timely manner and we had a much better experience with them this time around. We are very happy with how things turned out. Awful company. We paid over $38,000 to raise our foundation 1.5”. It started cracking and they were unable to do what they said they could. They “stabilized “ it and left with our savings. It was the biggest waste of money and I suggest you go elsewhere. Garbage. Our house feels like it’s sinking more.

So I had some work done by r and r back in 2019. I had six piers put in and really enjoyed Corey the owner… fast forward to 2026 and the other part of my house started having weird sounds and a crack in my ceiling… I live on a hillside and tons of water comes my way and a user error with a downspout may have caused more issues… I made an appointment to have him come Out and do an inspection with a bid…. It’s pretty rare these days to not feel like you have gotten taken… Cory did all the measurements and well it appears the house is just settling. The house was built in 1980 by the original owners and was definitely not built straight. Anyway… Cory literally put me at ease and said. “Let’s just keep these measurements and check them out in a year or so. “He could have easily have just said… “yup. You need six piers….” He didn’t. I highly recommend r and r foundation… thanks for being honest… it goes a long way! Also… when I do need the work done… I, of course, will be using them!

House built in 1913 did not disappoint with challenges with a leaking foundation into the basement. But, R&R came through and I am able to feel confident that any further water issues are no longer. If the opportunity presented itself, I would hire them again.

I had them come out to my house to look at an issue of water seeping into my garage which is built into a hill. For reasons that have nothing to do with them, I didn't end up getting the work done. However of the four companies I had look at it, R&R's assessment was easily the most thorough. They are the only one that did any significant inspection outside of the building rather than just inside the garage and their prices were comparable to the other companies I checked out.

Had R and R do some work on our older home that needed an update to the crawl space foundation posts a few years back. Work was accomplished in a timely and professional manner. Now in 2025, we are selling our home in a slow market and want to upgrade. We need to show the new buyers the application to transfer the foundation warranty ahead of the inspection in a few days as a show of good will to close the home. R and R's marketing manager, Jordan, was able to accomplish this promptly within one day for us and really set us up well to help close our home. While the foundation repair was important, it was years later, being able to connect with R and R again, and show the new buyers the work they had done and that it was done by a reputable company, that helped seal the deal.
