Foundation Repair Steilacoom
Foundation issues can lead to significant damage to your home if not taken care of promptly. In Steilacoom, WA, homeowners may notice signs like cracks in the floor, bowing walls, or sagging floors, which often indicate more serious structural concerns. You might also experience sticking doors, windows that won’t close properly, or noticeable gaps between walls and ceilings. These issues can signal that your foundation is shifting due to soil movement, water damage, or natural wear and tear over time.
At TerraFirma, we specialize in foundation repairs right here in Steilacoom, offering expert solutions that address the root cause of your foundation issues. Our process starts with a thorough inspection to evaluate both the severity and origin of the problem. From there, we suggest targeted foundation repair systems designed to effectively restore your home’s stability:
Foundation piers
In Steilacoom, our push and helical piers are expertly designed to stabilize and elevate your foundation by channeling its weight to deeper, more stable soil layers. Helical piers work best in areas with known soil conditions, while push piers are the ideal choice for those with uncertain soil stability. Both solutions are minimally invasive and provide lasting results.
Wall Stabilization Systems
For cracked, bowing, or leaning walls, we offer a suite of reinforcement products. These include:
- CarbonArmor®: Made from fiber-reinforced polymers ten times stronger than steel.
- PowerBrace®: Zinc-plated steel beams that can be tightened over time.
- GeoLock® Anchors and Helical Tiebacks: These systems halt inward movement and gradually straighten walls over time.
- EverBrace™: Designed for severely deteriorated walls, this system replaces and reinforces failing foundation walls with steel supports.
We also offer grouted micropile tiebacks for difficult soil conditions, SmartJack® crawl space support posts for sagging floors, and vapor barriers to manage humidity and prevent further moisture damage.
Every solution comes with professional installation, ongoing maintenance options, and transferable warranties, so you can have confidence and peace of mind in your Steilacoom home.

Even a tiny crack in your basement wall can turn into a significant entry point for moisture.

Crawl Space Repair Steilacoom
Crawl spaces may be easy to forget, but they play a vital role in your home’s structure and air quality here in Steilacoom.

Encapsulation & Drainage

- Sump pumps remove water quickly and efficiently, even during heavy rain or high water table conditions.

Crawl Space Entry & Vent Solutions
- EverLast™ Doors & Access Wells: Waterproof, durable entry systems that keep out pests and moisture.
- Turtl™ Access Well: An attractive, lockable access solution in several colors.

Earthquake Retrofitting Steilacoom, WA
Steilacoom, WA, is situated within an active seismic zone, making it important for homeowners to be aware of earthquake risks. Homes constructed before the updated building codes of the 1990s may be particularly at risk. Even a minor earthquake could lead to a home shifting off its foundation or suffering significant structural damage.
TerraFirma’s earthquake retrofitting services help secure your Steilacoom home to its foundation and strengthen its ability to withstand seismic events.
Enhancing your home with earthquake retrofitting in Steilacoom not only strengthens its resilience but can also lead to lower insurance premiums and deductibles, as well as open the door to coverage options that weren’t available before.
How We Retrofit
Assessment & Planning
In Steilacoom, WA, the retrofitting process starts with a thorough evaluation of your building’s current condition. Our skilled professionals, including structural engineers and trained technicians, will inspect your home to pinpoint any weaknesses and suggest the best solutions.
This assessment involves a thorough inspection of the foundation, walls, roof, and overall structure. Following that, our engineer will create a detailed retrofitting plan tailored to the results.
Foundation Bolting
Securing the foundation is the next step in the process. Our technicians will install anchor bolts that connect your home to its foundation, ensuring stability and preventing lateral movement during an earthquake.
Our process involves carefully drilling into the foundation and adding steel bolts. Our team then tightens these bolts to strengthen the structure, improving its stability and ability to withstand seismic forces right here in Steilacoom.
Adding Shear Walls
Shear walls play a vital role in earthquake retrofitting by helping to distribute seismic forces, ensuring that structures in Steilacoom remain safe and sound.
In Steilacoom, shear walls are typically made from durable materials like plywood and are strategically placed throughout homes, especially in areas known as cripple walls. This crucial addition enhances the structural support and stability of the walls, helping to minimize the risk of damage during an earthquake.
Bracing & Reinforcing
Next, we enhance key areas of your Steilacoom home by installing steel braces and straps. Our team secures these essential reinforcements to critical structural elements like the roof, walls, and floors. This important step boosts your home’s overall stability, ensuring it has a robust framework ready to withstand seismic forces.
Securing Applicances
Ensuring your appliances are secured helps create a safer living space for everyone in Steilacoom. It’s important to anchor items like water heaters and refrigerators, and our technicians can also install protective measures for gas meters to reduce the risk of leaks.
Reparing Foundations
During retrofitting, technicians may notice substantial foundation damage that needs immediate repair. Adding crawl space support posts and foundation piers, and stabilizing the walls are some of the ways TerraFirma can reinforce your foundation.

Homeowners Frequently Asked Questions
How does rain put my home at risk ?
Western Washington 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.
