Foundation Repair Montesano
Foundation problems can lead to significant damage to your home if not taken care of. If you’re in Montesano, WA, you might see signs like cracks in your floors, bowing walls, or sagging floors that could indicate more serious structural issues. Homeowners here often report doors that stick, windows that don’t close right, or gaps between walls and ceilings. These signs may point to shifting foundations caused by soil movement, water damage, or simply the aging of your home.
At TerraFirma, we specialize in foundation repairs in Montesano, offering expert solutions designed to address the unique causes of your foundation issues. Our process starts with a thorough inspection to determine the extent and source of the problem. From there, we recommend one or more of our reliable foundation repair systems:
Foundation piers
In Montesano, 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 best in areas with known soil conditions, while push piers are ideal for spots with uncertain stability. Both methods are minimally invasive and provide lasting solutions.
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, maintenance options, and transferable warranties, ensuring you feel confident and at ease in your Montesano home.
Basement Waterproofing Montesano
Dealing with a wet basement in Montesano, WA? It can lead to serious issues like mold, mildew, structural damage, and poor air quality in your home. You might notice musty odors, stained walls, puddles of water, or white powdery stains—known as efflorescence—left behind when water evaporates. Even a tiny crack in your basement wall can turn into a big problem by allowing moisture to seep in.
TerraFirma provides top-notch basement waterproofing solutions in Montesano, ensuring your space stays dry, healthy, and functional, whatever the weather brings.
Crawl Space Repair Montesano
Many homeowners in Montesano may overlook their crawl spaces, but these areas play a vital role in your home’s structure and air quality. If neglected, a crawl space can become a breeding ground for mold, pests, and standing water. These issues can result in wood rot, unpleasant odors, and even health concerns for you and your family.
We understand the unique crawl space conditions in Montesano, WA. That’s why TerraFirma offers specialized repair services to tackle moisture, mold, pests, and sagging floors with comprehensive solutions like 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 Montesano 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 Montesano
Damaged, cracked, or uneven concrete can be more than just an eyesore—it poses safety risks too. Issues like poor soil compaction, freeze-thaw cycles, erosion, or tree root growth can lead to these problems. Homeowners in Montesano trust us to promptly and effectively repair their concrete slabs, sidewalks, patios, and driveways.
TerraFirma provides quick, efficient, and durable concrete leveling and repair solutions in Montesano, WA, using cutting-edge polyurethane foam injection and expert crack sealing.
PolyLevel® Concrete Lifting
PolyLevel employs expanding polyurethane foam to lift and stabilize concrete slabs. This non-invasive method is perfect for residents of Montesano, WA looking to:
- 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 Montesano, WA for industrial buildings, warehouse floors, roads, runways, and rail lines—using the same high-quality systems we trust for residential properties.
Earthquake Retrofitting Montesano, WA
Montesano, WA, is located in an area prone to seismic activity, making homes built before the 1990s particularly at risk. Even a minor earthquake can lead to significant structural damage or cause a home to shift off its foundation.
TerraFirma’s earthquake retrofitting services help secure your Montesano home to its foundation and strengthen its ability to withstand seismic events.
Enhancing your home with earthquake retrofitting in Montesano not only boosts safety but can also lower your insurance premiums and deductibles, plus help you qualify for coverage that may not have been available before the upgrade.
How We Retrofit
Assessment & Planning
In Montesano, WA, the retrofitting process starts with a thorough assessment of your building’s current state. Our experts, including structural engineers and trained technicians, will inspect your home to pinpoint any weaknesses and suggest the best solutions.
This assessment covers a thorough inspection of the foundation, walls, roof, and overall structure. Afterward, the engineer will create a detailed retrofitting plan tailored to the findings.
Foundation Bolting
In Montesano, securing your home’s foundation is an important next step. Our technicians install anchor bolts to firmly connect your house to its foundation, safeguarding it against lateral movement during an earthquake.
In Montesano, WA, we start by drilling holes into your foundation and inserting sturdy steel bolts. Our skilled team then tightens these bolts to reinforce your structure, significantly boosting its stability and ability to withstand seismic forces.
Adding Shear Walls
Shear walls play a vital role in earthquake retrofitting here in Montesano, as they help distribute seismic forces and keep buildings from collapsing.
Shear walls are usually made of plywood or other durable materials and are strategically placed throughout homes, especially in cripple walls. They add extra support and stability to the structure, helping to reduce the risk of damage during an earthquake—something we take seriously here in Montesano.
Bracing & Reinforcing
Next, we’ll strengthen the key areas of your Montesano home with steel braces and straps. Our team installs these to important structural elements like the roof, walls, and floors. This process enhances your home’s stability, ensuring it has a strong framework that can endure seismic forces.
Securing Applicances
Ensuring your appliances are securely anchored is key to creating a safer living space for everyone in Montesano. Properly securing items like water heaters and refrigerators is essential, and our technicians can also install protective measures 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.

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.
