Foundation Repair Renton
Neglecting foundation issues can lead to significant damage to your home. If you’re in Renton, WA, keep an eye out for warning signs like cracked floors, bowing walls, or sagging floors, which may indicate more serious structural concerns. You might also notice doors that stick, windows that don’t close properly, or gaps between walls and ceilings. These issues can be signs that your foundation is shifting due to soil movement, water damage, or the natural aging process.
At TerraFirma, we specialize in foundation repair right here in Renton, offering expert solutions that address the unique causes of your foundation issues. We start with a thorough inspection to determine the extent and source of the problem, then recommend the most effective foundation repair systems tailored to your needs:
Foundation piers

- CarbonArmor®: Made from fiber-reinforced polymers ten times stronger than steel.

Earthquake Retrofitting Renton, WA
Renton, WA, is located in an active seismic zone, making it important for homeowners to be aware of earthquake preparedness. Homes built prior to the updated building codes of the 1990s may be particularly at risk. Even a small earthquake can lead to a house shifting off its foundation or suffering significant structural damage.
TerraFirma’s earthquake retrofitting services help secure your Renton home to its foundation and strengthen its ability to withstand seismic events.
In Renton, earthquake retrofitting not only enhances your home’s safety but can also help lower your insurance premiums and deductibles. Plus, you may qualify for coverage options that weren’t available before the upgrade.
How We Retrofit
Assessment & Planning
The retrofitting process starts with a thorough assessment of your building’s current condition. An experienced professional, like a structural engineer or a trained technician, will inspect your home to pinpoint any weaknesses and suggest the best solutions.
Our evaluation involves a thorough inspection of your home’s foundation, walls, roof, and overall structure. From these findings, our engineer will create a detailed retrofitting plan tailored to your needs in Renton.
Foundation Bolting
Securing the foundation is the next essential step for your home in Renton, WA. Our technicians expertly install anchor bolts to firmly connect your house to its foundation, ensuring stability and preventing lateral movement during potential earthquakes.
In Renton, we strengthen your home’s foundation by carefully drilling holes and installing steel bolts. Our team tightens these bolts to ensure your structure is secure, boosting its stability and resistance to seismic activity.
Adding Shear Walls
Shear walls play a vital role in earthquake retrofitting by helping to distribute seismic forces and keep buildings in Renton safe from collapse.
Shear walls, often made of plywood or other durable materials, are strategically placed throughout homes in Renton, especially in vulnerable areas like cripple walls. These walls enhance structural support and stability, helping to reduce the risk of damage during an earthquake.
Bracing & Reinforcing
Next, we focus on strengthening key areas of your home in Renton with durable steel braces and straps. Our team installs these vital supports on essential structural components like the roof, walls, and floors. This step enhances your home’s overall stability, ensuring it has a robust framework that can better withstand seismic activity.
Securing Applicances

Homeowners Frequently Asked Questions
How does rain put my home at risk ?
SeaTac soils are impacted by heavy rains causing hydrostatic pressure. This leads to cracks in foundations and basements and may cause your foundation to settle or sink. Engineered support structures and comprehensive drainage systems are key to keeping your home dry, safe, and stable.
What’s the best way to repair concrete?
The NexusPro solution is a commercial grade joint sealant that offers several advantages over traditional concrete crack repairs. Its fast cure time (60 minutes) and performance under extreme temperatures makes it a perfect match for concrete repairs.
What types of cracks in my foundation or basement should I be concerned with?
Houses are susceptible to cracks in basements due to heavy rains and wet soils. Watch out for horizontal or stair step cracking along the foundation wall, diagonal cracks in the corners, crumbling walls and inward bulges.
How to fix a leaking basement floor?
If you have water coming through the floor or windows to your basement, the first step is installing a perimeter drain system. We can also install a direct drainage channel, which will help direct any water that comes through the crack into the drain and your sump pump.
Are you noticing damp drywall and carpet in your basement?
Musty smells, walls that feel damp to the touch, and ground-level leaks are all indicators that your basement may need to be waterproofed. Don’t wait until the next heavy rain to protect your home from water damage.
Which vapor barrier is best for weeping walls?
The VaporLoc Elite Wall System is better for weeping walls than other commonly used vapor barriers. The VLE system has double sealed seams, waterproof material (not water-resistant), and is much thicker than vapor barriers available at retail stores.
Can I turn my crawl space into storage?
TerraFirma offers comprehensive encapsulation solutions to keep your crawl space clean, dry, and secure from outside threats. Our industry-leading vapor barrier system keeps out destructive moisture while greatly improving your indoor air quality. In most homes, TerraFirma can even encapsulate your crawl space, giving you a clean, dry area suitable for storage.
How to repair damaged concrete?
While you could seal concrete with urethane caulk found at your local big-box DIY store, that is a solution that is prone to cracking, bubbling and drying out over time. The local experts at TerraFirma are here to help with long lasting solutions to level seal your unprotected joints and cracked concrete.
What is that bad smell coming up from my drain?
Unwanted air and gasses are coming up through your home’s drain system. A great fix is our TrenchLock™ drain insert that can be installed in an existing trench drain to allow water down without allowing air to come up. The system comes with balls that fit over the drainage holes, which create an airtight seal when there is no water.
What is the difference between helical piers and push piers?
Helical piers and push piers are both types of foundation repair methods, but they differ in their design and installation process. The choice between helical piers and push piers depends on factors such as soil conditions and structural requirements. Helical piers are often preferred in areas with weak or unstable soil conditions.
How long does basement waterproofing last?
TerraFirma-installed waterproofing systems are expected to last decades with regular care & maintenance. We also warranty our installations, our WaterGuard and DryTrak drainage systems come with a transferrable lifetime warranty. Terms apply, view the details here. We stand by our work and the quality of the systems we install.

Every Terra Firma employee who came to our house; Bailey, Jorge, Robert and the rest of their team, were on-time, polite and did their job efficiently. They answered our questions, kept us updated on the work they were doing and cleaned up after themselves. I would definitely recommend this company.
I'd hire him in a minute.
Well they came, they saw, Oh Boy! I was not wrong, they were here 2.5 hrs and again, the house has had some movement and we need some more work to stabilize. We have some additional C.Y.A's to add to this round, as our neighborhood and home has lots of sand in the soil so we are going to be looking into getting a GEO Engineer out to see what is causing the movement.
I give all the back info, because I want you all to know, if you feel something is not right CALL and have your home looked at. TerraFirma is NOT redoing what they already did, this is all new issues, not their fault at all... Tulane and Sam are amazing, they took the time to explain and give us all options. The info they share through experience and knowledge is beyond me and it is so appreciated.
If you have any foundation, sinking driveways, walkways, stairs, cracking in your walls, around windows, doors.... Call these guys!
I hands down don't always do reviews but I do for these guys because they deserve to have their names out there so you know they are TAKING CARE of their customers the whole way through! 10/10 and then some.... THANK YOU!
