Foundation Repair White Salmon
Foundation problems can lead to significant damage to your home if not taken care of. If you’re in White Salmon, WA, you may start to see signs like cracks in your floors, bowing walls, or sagging floors—each of which could indicate more serious structural issues. Keep an eye out for sticking doors, windows that don’t close right, or gaps appearing between walls and ceilings. These signs may suggest that your foundation is shifting due to soil movement, water damage, or the natural aging of your home.
At TerraFirma, we specialize in foundation repair right here in White Salmon. Our expert team delivers targeted solutions designed specifically for the root cause of your foundation issues. We start with a thorough inspection to determine the extent and source of the problem, then recommend the best foundation repair methods that we know work.
Foundation piers
In White Salmon, WA, our push and helical piers are designed to stabilize and lift your foundation by transferring its load to deeper, more stable soil. Helical piers work best in areas with known soil conditions, while push piers are ideal for regions where soil stability is uncertain. Both options are minimally invasive and provide long-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 professional installation, ongoing maintenance options, and transferable warranties, ensuring you feel confident and at ease in your home in White Salmon.
Basement Waterproofing White Salmon
Dealing with a wet basement in White Salmon? It can lead to mold, mildew, and even structural damage, not to mention poor air quality in your home. Look out for signs like musty odors, stained walls, pooling water, or that chalky white residue left behind when water evaporates. Remember, even a small crack in your basement wall can quickly turn into a major entry point for moisture.
TerraFirma provides top-notch basement waterproofing solutions in White Salmon, ensuring your space stays dry, healthy, and functional—come rain or shine.
Crawl Space Repair White Salmon
Crawl spaces in White Salmon may be easy to overlook, but they play a vital role in your home’s structure and air quality. If left unchecked, a neglected crawl space can become a haven for mold, pests, and standing water. These issues can lead to wood rot, unpleasant odors, and even respiratory problems for you and your family.
We understand the unique crawl space challenges in White Salmon, WA. That’s why TerraFirma offers tailored crawl space repair services focused on tackling moisture, mold, pests, and sagging floors with comprehensive encapsulation, effective drainage solutions, and reliable 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 White Salmon 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 White Salmon
Damaged, cracked, or uneven concrete can be more than just an eyesore—it poses safety risks too. These issues may arise from factors like inadequate soil compaction, freeze-thaw cycles, erosion, or tree roots. That’s why homeowners in White Salmon trust us to repair their concrete slabs, sidewalks, patios, and driveways quickly and effectively.
TerraFirma provides quick, reliable, and durable concrete leveling and repair services in White Salmon, WA, utilizing 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. This non-invasive method is perfect for:
- 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 White Salmon, WA for industrial buildings, warehouse floors, roads, runways, and rail lines—using the same high-quality systems we trust for residential properties.
Earthquake Retrofitting White Salmon, WA
White Salmon, WA, is located in a region of the Pacific Northwest that is prone to seismic activity. Homes built before the updated building codes of the 1990s may be particularly at risk. Even a small earthquake can lead to a home shifting off its foundation or suffering significant structural damage.
TerraFirma’s earthquake retrofitting services help secure your White Salmon home to its foundation and strengthen its ability to withstand seismic events.
Earthquake retrofitting in White Salmon not only enhances your home’s safety but can also lower your insurance premiums and deductibles, plus help you qualify for coverage that wasn’t available before the upgrade.
How We Retrofit
Assessment & Planning
In White Salmon, 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 examine your home to pinpoint any weaknesses and suggest the best solutions.
Our evaluation looks at the foundation, walls, roof, and overall structure of your home. From there, our engineer creates a detailed retrofitting plan tailored to the specific findings.
Foundation Bolting
Next up, we secure the foundation. Our technicians install anchor bolts to firmly connect your home to its foundation, helping to keep it stable and secure in case of an earthquake.
Our process involves drilling into the foundation and adding strong steel bolts. Our team tightens these bolts to ensure the structure is secure, boosting its stability and helping it withstand seismic activity.
Adding Shear Walls
Shear walls play a vital role in earthquake retrofitting for White Salmon homes by helping to distribute seismic forces and keep your structure safe from collapsing.
In White Salmon, shear walls are usually made from plywood or other sturdy materials and are installed in key areas of your home, especially in cripple walls. These walls add essential support and stability, helping to minimize the risk of damage during an earthquake.
Bracing & Reinforcing
Next, we enhance and strengthen key areas of your home in White Salmon by installing steel braces and straps. Our team secures these to crucial structural components like the roof, walls, and floors. This essential step boosts your home’s overall stability, giving it a robust framework designed to withstand seismic forces.
Securing Applicances
By securing your appliances, you can ensure a safer living space for everyone in your home. It’s important to anchor items like water heaters and refrigerators. Our technicians also provide protection for gas meters to help minimize 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.

White Salmon
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.
