Foundation Repair Sherwood
Foundation problems can lead to significant damage to your home if not taken care of. Common signs to watch for include cracks in your floors, walls that bow, and sagging floors. Homeowners in Sherwood, OR may also notice doors that stick, windows that fail to close correctly, or visible gaps between walls and ceilings. These issues could indicate that your foundation is shifting due to soil movement, water damage, or aging. It’s important to address these symptoms promptly to protect your investment.
At TerraFirma, we specialize in foundation repair in Sherwood, offering targeted solutions designed to address the root cause of your foundation issues. Our process starts with a thorough inspection to evaluate the extent and source of the problem. From there, we’ll recommend one or more of our trusted foundation repair systems:
Foundation piers
In Sherwood, OR, our push and helical piers are expertly designed to stabilize and lift your foundation by transferring its weight to deeper, more stable soil. Helical piers work best for familiar soil conditions, while push piers are ideal for areas with uncertain soil stability. Both solutions are minimally invasive and provide lasting results.
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, so you can feel confident and at ease in your Sherwood home.
Basement Waterproofing Sherwood
Living in Sherwood, OR, you know how crucial it is to keep your home dry. A wet basement can lead to mold, mildew, structural damage, and poor air quality throughout your space. You might notice signs of water intrusion like musty odors, stained walls, pooling water, or efflorescence—a white, powdery residue that appears when water evaporates. Even a small crack in your basement wall can open the door for moisture troubles.
TerraFirma provides top-notch basement waterproofing solutions in Sherwood, ensuring your space stays dry, healthy, and functional—come rain or shine.
Crawl Space Repair Sherwood
Crawl spaces in Sherwood are often neglected, but they play a vital role in your home’s structure and air quality. If left unaddressed, a poor 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 those living in your home.
We understand the crawl space conditions in Sherwood, OR, and TerraFirma’s crawl space repair services are tailored to tackle moisture, mold, pests, and sagging floors with comprehensive encapsulation, effective drainage, and robust structural support.
Encapsulation & Drainage
We begin by sealing the crawl space with our Vapor Barrier, 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.
- Crawl Space 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 Sherwood 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 Basement 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 Sherwood
Damaged, cracked, or uneven concrete isn’t just an eyesore—it can be a safety risk too. These issues may arise from factors like inadequate soil compaction, freeze-thaw cycles, erosion, or tree root growth. That’s why Sherwood homeowners 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 right here in Sherwood, OR, utilizing advanced 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 homeowners in Sherwood 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 Sherwood, OR for industrial buildings, warehouse floors, roads, runways, and rail lines—using the same high-quality systems we trust for residential properties.
Earthquake Retrofitting Sherwood, OR
Sherwood, like much of the Pacific Northwest, is situated in an active seismic zone. Homes built before the updated building codes of the 1990s may be particularly at risk. Even a minor earthquake can lead to your home shifting off its foundation or suffering significant structural damage.
TerraFirma’s earthquake retrofitting services help secure your Sherwood home to its foundation and strengthen its ability to withstand seismic events.
Retrofitting your home for earthquakes in Sherwood can help lower your insurance premiums and deductibles, and may even make you eligible for coverage that wasn’t available before the upgrade.
How We Retrofit
Assessment & Planning
In Sherwood, OR, the retrofitting process starts with a thorough assessment of your building’s current condition. A knowledgeable expert, like a structural engineer or trained technician, will inspect your home to pinpoint any weaknesses and suggest the best solutions tailored to your needs.
This assessment covers the foundation, walls, roof, and overall structure of your home. After that, our engineer will create a detailed retrofitting plan tailored to the results.
Foundation Bolting
Securing the foundation is a crucial next step for homes in Sherwood, OR. Our technicians expertly install anchor bolts to firmly connect your house to its foundation, helping to prevent any lateral movement during an earthquake.
Our process begins by drilling holes into your foundation and inserting sturdy steel bolts. Our team then tightens these bolts to reinforce your structure, increasing its stability and ability to withstand seismic forces.
Adding Shear Walls
Shear walls play a vital role in earthquake retrofitting by helping to distribute seismic forces and keep structures in Sherwood safe from collapsing.
Shear walls, usually made from sturdy materials like plywood, are strategically placed throughout homes in Sherwood, especially in areas known as cripple walls. These additions enhance the strength and stability of your walls, helping to minimize the risk of damage during an earthquake.
Bracing & Reinforcing
Next, we enhance and strengthen vital areas of your home in Sherwood with durable steel braces and straps. Our team expertly installs these reinforcements on essential structural elements like the roof, walls, and floors. This crucial step boosts your home’s stability, creating a robust framework designed to withstand seismic activity.
Securing Applicances
Securing your appliances is key to creating a safer home for everyone in Sherwood, OR. Anchoring essential items like water heaters and refrigerators can make a real difference. Our technicians can also provide protection 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.

Sherwood
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 Vapor Barrier 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 Grated Trench 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 Basement Drainage System and Perimeter Drainage System 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.
