Foundation Repair Stevenson
Foundation issues can lead to significant damage to your home if not taken care of. If you notice signs like cracks in the floors, bowed walls, or sagging floors, these can indicate underlying structural problems. Homeowners in Stevenson, WA may find that doors stick, windows won’t close quite right, or there are noticeable gaps between walls and ceilings. These symptoms could suggest that your foundation is shifting due to soil movement, water damage, or simply the wear and tear of time.
In Stevenson, TerraFirma specializes in foundation repairs with expert solutions designed specifically for the unique issues affecting your home. We start with a thorough inspection to determine the extent and source of your foundation concerns. From there, we recommend one or more of our tried-and-true foundation repair systems:
Foundation piers
In Stevenson, WA, our push and helical piers are designed to stabilize and lift your foundation by shifting its load to deeper, more stable soil. Helical piers are well-suited for areas with known soil conditions, while push piers excel in regions where soil stability is uncertain. Both systems are minimally invasive and provide lasting solutions for your foundation needs.
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 expert installation, ongoing maintenance options, and transferable warranties, providing you with confidence and peace of mind in your home in Stevenson.
Basement Waterproofing Stevenson
Having a damp basement in Stevenson can cause mold, mildew, structural issues, and affect the air quality in your home. Signs of water intrusion might include musty odors, stained walls, puddles, or even efflorescence—a white, powdery residue that appears when water evaporates. Remember, even a tiny crack in your basement wall can turn into a significant entry point for moisture.
At TerraFirma, we provide top-notch basement waterproofing solutions in Stevenson that ensure your space stays dry, healthy, and functional, come rain or shine.
Crawl Space Repair Stevenson
Crawl spaces in Stevenson, WA, are often forgotten, but they play a vital role in your home’s structure and air quality. If neglected, they can become breeding grounds for mold, pests, and standing water. These issues can lead to wood rot, unpleasant odors, and even health problems for your family.
At TerraFirma, we understand the unique crawl space challenges in Stevenson, WA. Our expert crawl space repair services are tailored to tackle moisture, mold, pests, and sagging floors with effective solutions like full encapsulation, drainage, and structural support.
Encapsulation & Drainage
We begin by sealing the crawl space with our VaporLoc Elite liner, a 120-mil thick waterproof barrier that blocks moisture, soil gases, and allergens. To ensure proper drainage:
- We use drainage matting under the liner to guide water to your perimeter drain or sump pump.
- 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.
- Vent Covers: Sealing crawl space vents prevent outdoor air, moisture, and insects from entering.
Crawlspace repair in Stevenson is crucial to maintaining your home’s overall health and energy efficiency.
Structural Repairs
To support sagging or weak floor joists, our SmartJack® Support Posts offer adjustable, galvanized steel columns that restore floor stability. These are fast to install and offer permanent results.
Dehumidifiers & Monitoring
Install a SaniDry Sedona dehumidifier to maintain healthy humidity levels year-round. For added security, our ShipShape™ System offers 24/7 performance monitoring, proactive maintenance alerts, and remote control of your crawl space systems.
Concrete Repair Stevenson
Chipped, cracked, or uneven concrete isn’t just an eyesore—it can also pose safety risks. Issues like these can arise from various factors such as poor soil compaction, freeze-thaw cycles, erosion, or even tree roots. That’s why homeowners in Stevenson rely on us for fast and effective solutions for their concrete slabs, sidewalks, patios, and driveways.
At TerraFirma, we provide quick, clean, and durable concrete leveling and repair solutions right here in Stevenson, WA, using state-of-the-art polyurethane foam injection and crack sealing techniques.
PolyLevel® Concrete Lifting
PolyLevel utilizes expanding polyurethane foam to lift and stabilize concrete slabs, making it a non-invasive solution that’s perfect for the needs in Stevenson, WA:
- Sidewalks – Eliminates tripping hazards and restores smooth walkways.
- Driveways – Prevents further cracking and improves curb appeal.
- Patios, Porches, and Pool Decks – Ensures proper drainage and surface stability.
NexusPro™ Crack & Joint Sealant
To prevent water intrusion that can lead to further sinking, we apply NexusPro, a UV-resistant silicone-based joint sealant that:
- Cures in just 60 minutes.
- Withstands extreme weather and heavy use.
- Includes color-matched sand for a clean, polished look.
SealantPro™ Concrete Protection
After sealing and lifting your concrete, SealantPro provides a long-term barrier against moisture, chemicals, and seasonal temperature changes. It penetrates deep into concrete to resist stains, flaking, and surface erosion.
We also provide commercial concrete repair in Stevenson, WA for industrial buildings, warehouse floors, roads, runways, and rail lines—using the same high-quality systems we trust for residential properties.
Earthquake Retrofitting Stevenson, WA
Stevenson, WA is situated in an active seismic zone, making it important for homeowners to be aware of the risks. Homes built before the updated building codes of the 1990s may be particularly at risk. Even a minor earthquake can lead to homes shifting off their foundations or sustaining significant structural damage.
TerraFirma’s earthquake retrofitting services help secure your Stevenson home to its foundation and strengthen its ability to withstand seismic events.
Earthquake retrofitting in Stevenson not only helps protect your home but can also lower your insurance premiums and deductibles, plus open the door to coverage options you didn’t have before.
How We Retrofit
Assessment & Planning
In Stevenson, WA, the retrofitting process starts with a thorough assessment of your building’s current condition. A skilled professional, like a structural engineer or trained technician, will inspect your home to pinpoint any weaknesses and suggest the best solutions.
This evaluation looks at the foundation, walls, roof, and overall structure of your property. Afterward, our engineer creates a detailed retrofitting plan tailored to the findings.
Foundation Bolting
Securing the foundation is the next important step in our process. Our technicians install anchor bolts to firmly connect your home to its foundation, ensuring stability and preventing any lateral movement during an earthquake.
In Stevenson, WA, we enhance the stability of your foundation by drilling holes and inserting sturdy steel bolts. Our skilled workers then securely tighten these bolts, boosting your structure’s resistance to seismic forces.
Adding Shear Walls
In Stevenson, WA, shear walls play a vital role in earthquake retrofitting by helping to distribute seismic forces and keeping buildings safe from collapse.
In Stevenson, WA, shear walls are usually made of plywood or similar sturdy materials, strategically placed around your home, especially in vulnerable areas like cripple walls. These walls offer extra support and stability, helping to minimize the risk of damage in the event of an earthquake.
Bracing & Reinforcing
Next, we’ll strengthen key areas of your home in Stevenson, WA, using durable steel braces and straps. Our team will securely attach these reinforcements to essential structural elements like the roof, walls, and floors. This important step enhances your home’s overall stability, providing a robust framework designed to withstand seismic forces.
Securing Applicances
Securing your appliances can help create a safer living environment in Stevenson. It’s important to anchor items like water heaters and refrigerators. Our technicians can also install protective measures for gas meters to reduce the risk of gas 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 ?
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.
