Foundation Repair Winchester
Foundation issues can lead to significant damage to your home if not taken care of. If you’re in Winchester, OR, keep an eye out for signs like cracks in your floors, bowing walls, or sagging floors. You might also notice doors sticking, windows that won’t shut properly, or gaps appearing between your walls and ceilings. These issues could indicate a shifting foundation caused by soil movement, water damage, or wear and tear over time.
At TerraFirma, we provide specialized foundation repair services in Winchester, OR, designed to address the specific issues affecting your home. Our process starts with a thorough inspection to identify the root cause of any foundation concerns. From there, we recommend one or more of our trusted foundation repair solutions to restore your peace of mind.
Foundation piers
Our push and helical piers are expertly designed to stabilize and lift your foundation by transferring its weight to deeper, more stable soil beneath Winchester. Helical piers work well in areas with known soil conditions, while push piers are great for spots where soil stability is uncertain. Both options are minimally invasive and provide long-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 we offer in Winchester comes with expert installation, ongoing maintenance options, and transferable warranties, providing you with confidence and peace of mind in your home.
Basement Waterproofing Winchester
Having a wet basement in Winchester, OR, can create a host of 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, puddles, or efflorescence, which is a white, powdery residue left behind when water evaporates. Even a tiny crack in your basement wall can turn into a significant gateway for moisture.
TerraFirma provides top-notch basement waterproofing solutions in Winchester, ensuring your space stays dry, healthy, and functional—regardless of the weather.
Crawl Space Repair Winchester
Don’t underestimate your crawl space! In Winchester, it plays a vital role in your home’s structure and air quality. If left unattended, it can become a breeding ground for mold, pests, and standing water. These problems can lead to wood rot, unpleasant odors, and respiratory issues for your family.
We understand the crawl space conditions in Winchester, OR, and TerraFirma’s crawl space repair services are tailored to tackle moisture, mold, pests, and sagging floors with comprehensive solutions like full encapsulation, effective drainage, and reliable 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 Winchester 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 Winchester
Damaged, cracked, or uneven concrete isn’t just an eyesore—it can also pose a safety risk. These issues may arise from factors like poor soil compaction, freeze-thaw cycles, erosion, or tree roots. Homeowners in Winchester trust us to quickly and effectively repair their concrete slabs, sidewalks, patios, and driveways.
TerraFirma provides quick, efficient, and durable concrete leveling and repair services for Winchester, OR, utilizing advanced polyurethane foam injection and crack sealing techniques.
PolyLevel® Concrete Lifting
PolyLevel utilizes expanding polyurethane foam to lift and stabilize concrete slabs right here in Winchester, OR. This non-invasive solution is perfect for:
- 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.

Earthquake Retrofitting Winchester, OR
Winchester, OR, is located in an active seismic zone, making homes built before the updated codes in the 1990s particularly at risk. Even a small earthquake can lead to homes shifting off their foundations or suffering significant structural damage.
TerraFirma’s earthquake retrofitting services help secure your Winchester home to its foundation and strengthen its ability to withstand seismic events.
In Winchester, getting your home retrofitted for earthquakes can help lower your insurance premiums and deductibles, plus it may make you eligible for coverage options that weren’t available before the upgrade.
How We Retrofit
Assessment & Planning
In Winchester, OR, the retrofitting process starts with a comprehensive assessment of your building’s current condition. A qualified expert, like a structural engineer or trained technician, will inspect your home to pinpoint any weaknesses and suggest the right solutions.
This assessment involves a thorough inspection of the foundation, walls, roof, and overall structure. Following this, our engineer creates a detailed retrofitting plan tailored to the findings.
Foundation Bolting
Securing the foundation is the next step in the process. Our technicians install anchor bolts to firmly connect your home to its foundation, keeping it stable and preventing any side-to-side movement during an earthquake.
Our process includes drilling into the foundation and installing steel bolts, which are then tightened to reinforce the structure. This method significantly improves stability and helps it withstand seismic activity, making your home in Winchester more secure.
Adding Shear Walls
Shear walls are essential for earthquake retrofitting in Winchester, as they help distribute seismic forces and keep structures from collapsing.
Shear walls, often made of plywood or other sturdy materials, are strategically placed in homes throughout Winchester, particularly in vulnerable areas like cripple walls. These essential features enhance the walls’ support and stability, helping to minimize the risk of damage during an earthquake.
Bracing & Reinforcing
Next, we enhance the critical areas of your Winchester home by adding steel braces and straps. Our team carefully installs these on essential structural elements like the roof, walls, and floors. This vital step boosts your home’s stability, creating a robust framework designed to withstand seismic forces.
Securing Applicances
Anchoring appliances in your Winchester home can help create a safer living environment. It’s important to secure items like water heaters and refrigerators. Our technicians will 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.

Winchester
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.
