Foundation Repair Scotts Mills
Foundation issues can lead to significant damage to your home if not dealt with promptly. If you’re seeing signs like cracked floors, bowing walls, or sagging floors, it may indicate more serious structural concerns. Homeowners in Scotts Mills, OR, might also notice doors that stick, windows that won’t close right, or visible gaps between walls and ceilings. These symptoms could mean your foundation is shifting due to factors like soil movement, water damage, or wear and tear over time.
At TerraFirma, we specialize in foundation repairs right here in Scotts Mills. Our expert team provides customized solutions designed to address the specific issues affecting your foundation. We start with a thorough inspection to determine the cause and extent of the problem, and then we recommend one or more of our trusted foundation repair systems:
Foundation piers
In Scotts Mills, our push and helical piers are expertly designed to stabilize and lift your foundation by shifting its weight to deeper, more stable soil layers. Helical piers work great in areas with predictable soil conditions, while push piers are the go-to choice where soil stability is uncertain. Both methods 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 expert installation, ongoing maintenance options, and transferable warranties, ensuring you feel confident and at ease in your Scotts Mills home.
Basement Waterproofing Scotts Mills
Here in Scotts Mills, a wet basement can create serious problems like mold, mildew, structural damage, and poor air quality in your home. You might notice signs of water intrusion, such as musty odors, stained walls, standing water, or efflorescence—a white, powdery residue left when water evaporates. Even a tiny crack in your basement wall can turn into a significant pathway for moisture.
TerraFirma provides top-notch basement waterproofing solutions in Scotts Mills, ensuring your space stays dry, healthy, and fully functional—come rain or shine.
Crawl Space Repair Scotts Mills
Don’t underestimate your crawl space—it’s an essential part of your home’s structure and air quality here in Scotts Mills. If left neglected, it can become a breeding ground 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 crawl space conditions in Scotts Mills, OR, and TerraFirma’s repair services are tailored to tackle issues like moisture, mold, pests, and sagging floors. Our solutions include 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 Scotts Mills 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 Scotts Mills
Damaged, cracked, or uneven concrete isn’t just an eyesore—it can pose safety risks too. These issues may arise from poor soil compaction, freeze-thaw cycles, erosion, or even tree roots. That’s why homeowners in Scotts Mills trust us to promptly and effectively repair their concrete slabs, sidewalks, patios, and driveways.
TerraFirma provides quick, tidy, and durable concrete leveling and repair services in Scotts Mills, OR, using state-of-the-art polyurethane foam injection and crack sealing techniques.
PolyLevel® Concrete Lifting
PolyLevel employs expanding polyurethane foam to lift and stabilize concrete slabs. This non-invasive method is perfect for residents of Scotts Mills, OR, who are 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 Scotts Mills, OR for industrial buildings, warehouse floors, roads, runways, and rail lines—using the same high-quality systems we trust for residential properties.
Earthquake Retrofitting Scotts Mills, OR
Scotts Mills, like much of the Pacific Northwest, is located in an area with seismic activity. Homes built before the updated building codes of the 1990s may be particularly at risk. Even a minor earthquake can lead to a home shifting off its foundation or suffering significant structural damage.
TerraFirma’s earthquake retrofitting services help secure your Scotts Mills home to its foundation and strengthen its ability to withstand seismic events.
Earthquake retrofitting in Scotts Mills not only strengthens your home but can also lower your insurance premiums and deductibles, potentially making you eligible for coverage options that weren’t available before the upgrade.
How We Retrofit
Assessment & Planning
In Scotts Mills, OR, the retrofitting process starts with a thorough evaluation of your building’s current condition. A qualified expert, like a structural engineer or trained technician, will assess your home to pinpoint any weaknesses and suggest the best solutions.
This assessment involves checking the foundation, walls, roof, and overall structure. Following that, our engineer creates a detailed retrofitting plan based on their findings.
Foundation Bolting
To ensure your home in Scotts Mills is safe from earthquakes, the next step is securing the foundation. Our skilled technicians will install anchor bolts to firmly connect your house to its foundation, preventing any lateral movement in case of seismic activity.
Our process includes drilling holes into the foundation and inserting steel bolts. Our team tightens these bolts to reinforce the structure, improving its stability and making it more resilient against seismic activity.
Adding Shear Walls
In Scotts Mills, OR, shear walls play a vital role in earthquake retrofitting by helping to distribute seismic forces, which can protect your home from collapsing during an earthquake.
In Scotts Mills, OR, shear walls are usually made from plywood or other sturdy materials and are strategically placed throughout homes, especially in areas known as cripple walls. These walls offer extra support and stability, helping to minimize the risk of damage during an earthquake.
Bracing & Reinforcing
Next, we’ll fortify key areas of your home in Scotts Mills with sturdy steel braces and straps. Our team carefully installs these to crucial structural elements like the roof, walls, and floors. This process boosts your home’s overall stability, giving it a robust framework designed to withstand seismic forces.
Securing Applicances
By securing your appliances, you can create a safer living space for everyone in Scotts Mills. It’s important to anchor items like water heaters and refrigerators. Our technicians can also install safeguards for gas meters, helping 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.
