Foundation Repair Naselle
Foundation problems can lead to significant damage to your home if not taken care of. In Naselle, WA, homeowners may notice signs like cracks in the floors, bowing walls, and sagging floors, which often indicate more serious structural issues. You might also experience doors that stick, windows that won’t shut correctly, or gaps between walls and ceilings. These issues can signal that your foundation is shifting due to soil movement, water damage, or simply the wear and tear of time.
At TerraFirma, we specialize in foundation repairs in Naselle, offering expert solutions designed to address the specific issues affecting your home. Our process starts with a thorough inspection to determine the extent and source of the problem. From there, we’ll recommend one or more of our reliable foundation repair systems to ensure your home is secure and stable.
Foundation piers
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 ideal for locations with uncertain soil stability. Both options are minimally invasive and provide lasting solutions for your property in Naselle.
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, so you can feel confident and at ease in your Naselle home.
Basement Waterproofing Naselle
A damp basement can cause serious issues like mold, mildew, structural damage, and poor air quality in your home. In Naselle, you might notice signs of water intrusion such as musty odors, stained walls, pooling water, or a white, powdery substance known as efflorescence that appears when water evaporates. Even a small crack in your basement wall can turn into a big problem for moisture.
TerraFirma provides top-notch basement waterproofing solutions in Naselle, ensuring your space stays dry, healthy, and functional in any weather.
Crawl Space Repair Naselle
Crawl spaces may not be the first thing on your mind, but they play an essential role in the structure and air quality of your Naselle home. If left unattended, a neglected crawl space can become a breeding ground for mold, pests, and standing water. These problems can cause wood rot, unpleasant odors, and even respiratory issues for you and your family.
At TerraFirma, we understand the unique crawl space conditions in Naselle, WA. Our specialized crawl space repair services tackle issues like moisture, mold, pests, and sagging floors through complete encapsulation, effective drainage solutions, and sturdy 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 Naselle 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 Naselle
Damaged, cracked, or uneven concrete isn’t just an eyesore—it’s a safety risk. Issues like poor soil compaction, freeze-thaw cycles, erosion, or tree root growth can lead to these problems. That’s why homeowners in Naselle trust us to quickly and effectively repair their concrete slabs, sidewalks, patios, and driveways.
TerraFirma provides quick, efficient, and durable concrete leveling and repair solutions in Naselle, WA, using cutting-edge polyurethane foam injection and expert crack sealing.
PolyLevel® Concrete Lifting
PolyLevel uses expanding polyurethane foam to lift and stabilize concrete slabs. This non-invasive method is perfect for residents of Naselle, WA, looking to improve their surfaces by:
- 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 Naselle, WA for industrial buildings, warehouse floors, roads, runways, and rail lines—using the same high-quality systems we trust for residential properties.
Earthquake Retrofitting Naselle, WA
Naselle, WA, is located in an area of the Pacific Northwest that’s known for its seismic activity. Homes built before the 1990s, when updated building codes were implemented, may be particularly at risk. Even a small earthquake can make a house shift off its foundation or lead to significant structural damage.
TerraFirma’s earthquake retrofitting services help secure your Naselle home to its foundation and strengthen its ability to withstand seismic events.
By retrofitting your home in Naselle for earthquakes, you can not only enhance its safety but also potentially lower your insurance premiums and deductibles, plus gain access to coverage options that weren’t available before the upgrade.
How We Retrofit
Assessment & Planning
In Naselle, the retrofitting process starts with a thorough assessment of your building’s current condition. Our skilled professionals, including structural engineers and trained technicians, will carefully inspect your home to identify any weaknesses and suggest the best solutions for improvement.
This evaluation involves inspecting the foundation, walls, roof, and overall structure. After that, our engineer will create a thorough retrofitting plan tailored to the findings.
Foundation Bolting
In Naselle, securing your home’s foundation is the crucial next step. Our technicians will install anchor bolts that connect your house to its foundation, ensuring stability and preventing any lateral movement during an earthquake.
In this process, we drill into the foundation and install steel bolts. Our team then tightens these bolts to reinforce the structure, improving its stability and resistance to seismic activity.
Adding Shear Walls
Shear walls play an essential role in earthquake retrofitting for buildings in Naselle, WA. They help distribute seismic forces, keeping structures safe and secure during tremors.
Shear walls, made from plywood or other durable materials, are installed in key areas of your home, especially in cripple walls. These vital structures offer extra support and stability, helping to safeguard your home against potential earthquake damage.
Bracing & Reinforcing
Next, we’ll reinforce essential areas of your home in Naselle with sturdy steel braces and straps. Our team carefully installs these to key structural components like the roof, walls, and floors. This process boosts your home’s overall stability, creating a resilient framework ready to handle any seismic challenges.
Securing Applicances
Keeping your appliances secure helps create a safer living space for everyone in Naselle. It’s important to anchor items like water heaters and refrigerators. Our technicians 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.
