Foundation Repair Winston
Foundation issues can lead to significant damage to your home if not dealt with promptly. In Winston, OR, homeowners may notice signs like cracks in the floors, bowing walls, or sagging floors, which often indicate deeper structural concerns. You might find that doors are sticking, windows aren’t closing properly, or there are noticeable gaps between walls and ceilings. These issues could suggest your foundation is shifting due to soil movement, water damage, or the natural aging of your home.
At TerraFirma, we specialize in foundation repairs right here in Winston, offering expert solutions tailored to the specific issues affecting your foundation. Our process starts with a thorough inspection to identify the root cause of the problem. From there, we recommend one or more of our reliable foundation repair systems:
Foundation piers
Our push and helical piers are designed to stabilize and lift your foundation by shifting its weight to deeper, more stable soil. Helical piers are great for predictable soil conditions, while push piers are the go-to choice for areas with uncertain soil stability. Both options are minimally invasive and provide long-lasting solutions for your home in Winston.
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 have confidence and peace of mind in your Winston home.
Basement Waterproofing Winston
Living in Winston, OR, a wet basement can bring a host of problems, including mold, mildew, structural damage, and poor air quality in your home. You might notice signs of water intrusion through musty odors, stained 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 gateway for moisture.
TerraFirma provides state-of-the-art basement waterproofing solutions in Winston, ensuring your space stays dry, healthy, and functional—regardless of the weather.
Crawl Space Repair Winston
Crawl spaces are often forgotten, but they play a vital role in the structure and air quality of your home in Winston, OR. If left unattended, 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 crawl space conditions in Winston, OR, and TerraFirma’s crawl space repair services are tailored to tackle moisture, mold, pests, and sagging floors with effective 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 Winston 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 Winston
Damaged, cracked, or uneven concrete isn’t just an eyesore—it’s a safety concern. These issues can arise from poor soil compaction, freeze-thaw cycles, erosion, or tree roots. Homeowners in Winston trust us to repair their concrete slabs, sidewalks, patios, and driveways promptly and efficiently.
TerraFirma provides quick, efficient, and durable concrete leveling and repair solutions in Winston, OR, utilizing cutting-edge polyurethane foam injection and expert crack sealing.
PolyLevel® Concrete Lifting
PolyLevel utilizes expanding polyurethane foam to effectively raise and stabilize concrete slabs. This non-invasive solution is perfect for residents of Winston, 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 Winston, OR for industrial buildings, warehouse floors, roads, runways, and rail lines—using the same high-quality systems we trust for residential properties.
Earthquake Retrofitting Winston, OR
Winston, OR, is located in a region of the Pacific Northwest that sits in an active seismic zone. Homes built before the updated building codes from the 1990s may be at higher risk. Even a small earthquake could cause significant issues, such as shifting a home off its foundation or leading to serious structural damage.
TerraFirma’s earthquake retrofitting services help secure your Winston home to its foundation and strengthen its ability to withstand seismic events.
Upgrading your home in Winston with earthquake retrofitting not only enhances safety but can also help lower your insurance premiums and deductibles while opening up access to coverage that might not have been available before.
How We Retrofit
Assessment & Planning
In Winston, OR, the retrofitting process starts with a thorough assessment of your building’s current condition. Our qualified experts, including structural engineers and trained technicians, will inspect your home to pinpoint any weaknesses and suggest the best solutions.
This evaluation includes inspecting the foundation, walls, roof, and overall structure. Next, the engineer will create a detailed retrofitting plan tailored to the findings.
Foundation Bolting
Securing the foundation is the next crucial step in the process. Our technicians install anchor bolts to firmly connect your home to its foundation, ensuring it remains stable during an earthquake, right here in Winston.
Our approach in Winston, OR, includes carefully drilling holes into the foundation and inserting sturdy steel bolts. Once tightened, these bolts help secure the structure, boosting its stability and ability to withstand seismic forces.
Adding Shear Walls
Shear walls play a vital role in earthquake retrofitting in Winston, OR, helping to distribute seismic forces and keep buildings safe from collapsing during quakes.
Shear walls in homes often use sturdy materials like plywood, installed in key spots, especially in cripple walls. This extra support and stability help protect your home during an earthquake, giving you peace of mind here in Winston, OR.
Bracing & Reinforcing
Next, we’ll strengthen crucial areas of your home in Winston with sturdy steel braces and straps. Our team expertly installs these reinforcements on vital structural components like the roof, walls, and floors. This step enhances your home’s overall stability, ensuring it’s equipped to handle seismic events with a strong and resilient framework.
Securing Applicances
Securing your appliances can help create a safer living environment for everyone in your home. It’s important to anchor items like water heaters and refrigerators. Our technicians can also install safety 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.
