Foundation Repair Ocean Shores
Foundation problems can lead to significant damage if they’re not taken care of. In Ocean Shores, WA, homeowners might find floor cracks, bowing walls, or sagging floors as warning signs of more serious structural issues. You may also notice doors that are hard to open, windows that don’t close smoothly, or gaps appearing between walls and ceilings. These symptoms can indicate that your foundation is shifting due to soil movement, water damage, or wear and tear over time.
At TerraFirma, we specialize in foundation repairs in Ocean Shores, offering expert solutions designed specifically for the unique challenges your foundation may face. Our process starts with a thorough inspection to identify the extent and root cause of the issue. From there, we recommend one or more of our reliable foundation repair systems to get your home back on solid ground.
Foundation piers
At Ocean Shores, WA, our push and helical piers are designed to stabilize and lift your foundation by transferring its weight to deeper, more stable soil. Helical piers work great in areas with known soil conditions, while push piers are perfect for locations where soil stability is uncertain. Both systems are minimally invasive and provide you with lasting solutions for your home.
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 Ocean Shores home.
Basement Waterproofing Ocean Shores
In Ocean Shores, a damp basement can result in mold, mildew, structural issues, and reduced air quality in your home. Water intrusion might manifest as musty odors, discolored walls, standing water, or efflorescence—a white, powdery residue that appears when water evaporates. Even a tiny crack in your basement wall can become a significant gateway for moisture.
TerraFirma provides top-notch basement waterproofing solutions in Ocean Shores, ensuring your space stays dry, healthy, and functional all year round—regardless of the weather.
Crawl Space Repair Ocean Shores
Don’t underestimate your crawl space! In Ocean Shores, WA, this often-overlooked part of your home is vital for both its structure and your indoor air quality. If ignored, a neglected crawl space can become a breeding ground for mold, pests, and standing water. These problems can lead to wood rot, unpleasant odors, and even respiratory issues for you and your family.
We understand the unique conditions of crawl spaces in Ocean Shores, WA. That’s why TerraFirma offers tailored crawl space repair services to tackle moisture, mold, pests, and sagging floors with comprehensive 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 Ocean Shores 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.

Earthquake Retrofitting Ocean Shores, WA
Here in Ocean Shores, WA, we’re located in an area that experiences seismic activity. Homes built before the updated building codes of the 1990s may be at greater risk. Even a small earthquake can lead to significant issues, like shifting off their foundation or suffering serious structural damage.
TerraFirma’s earthquake retrofitting services help secure your Ocean Shores home to its foundation and strengthen its ability to withstand seismic events.
Upgrading your home with earthquake retrofitting in Ocean Shores not only boosts safety but can also help lower your insurance premiums and deductibles, plus you may qualify for coverage options that weren’t available before.
How We Retrofit
Assessment & Planning
The retrofitting process in Ocean Shores starts with a thorough evaluation of your building’s current condition. Our skilled experts, including structural engineers and trained technicians, will inspect your home to pinpoint any weaknesses and suggest the best solutions for your needs.
This assessment involves a thorough inspection of the foundation, walls, roof, and overall structure. Next, our engineer will create a detailed retrofitting plan tailored to the findings.
Foundation Bolting
Securing the foundation is a crucial next step in the process. Our technicians install anchor bolts to firmly connect your home to its foundation, ensuring it stays stable during any earthquakes that may occur near Ocean Shores.
Our process involves carefully drilling into the foundation and inserting sturdy steel bolts. Once in place, our team tightens the bolts to reinforce the structure, boosting its stability and making it more resistant to seismic activity—ideal for ensuring safety in beautiful Ocean Shores, WA.
Adding Shear Walls
Shear walls play a vital role in earthquake retrofitting by helping to distribute seismic forces, ensuring buildings in Ocean Shores, WA, remain safe and sturdy during an earthquake.
Shear walls, made from sturdy materials like plywood, are strategically placed throughout homes in Ocean Shores, especially in areas like cripple walls. These walls enhance the overall support and stability of your home, helping to reduce the risk of damage during an earthquake.
Bracing & Reinforcing
Next, we enhance your home’s strength by installing durable steel braces and straps in key areas. Our team secures these to important structural elements like the roof, walls, and floors. This vital step boosts your home’s stability, ensuring it has a solid framework capable of withstanding seismic activity.
Securing Applicances
Ensuring that your appliances are securely anchored creates a safer living space for everyone in Ocean Shores. It’s vital to secure items like water heaters and refrigerators, and our technicians can also install protective measures for gas meters to help 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.
