Foundation Repair Reedsport
Foundation issues can lead to significant damage to your home if not taken care of promptly. Signs like cracks in the floor, bowing walls, and sagging floors often indicate more serious structural problems. If you’re a homeowner in Reedsport, OR, you might notice doors that stick, windows that won’t close properly, or gaps appearing between your walls and ceilings. These issues could all be symptoms of a shifting foundation due to soil movement, water damage, or natural wear and tear over time.
At TerraFirma, we specialize in foundation repair in Reedsport, offering expert solutions customized to address the specific issues affecting your foundation. We start with a thorough inspection to identify the root cause of the problem. From there, we’ll suggest one or more of our reliable repair systems to get your home back on solid ground:
Foundation piers
Our push and helical piers are designed to securely stabilize and lift your foundation by directing its weight to deeper, more stable soil. Helical piers are great for familiar soil conditions, while push piers work best where soil stability is uncertain. Both methods are minimally invasive and provide long-lasting solutions for your home in Reedsport.
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, so you can enjoy confidence and peace of mind in your Reedsport home.
Basement Waterproofing Reedsport
Living in Reedsport, OR, you know that a wet basement can spell trouble. It can invite mold, mildew, structural issues, and even compromise the air quality in your home. You might notice signs of water intrusion, like musty odors, stained walls, standing water, or white powdery residue from evaporated water. Remember, even a tiny crack in your basement wall can turn into a significant source of moisture.
TerraFirma provides top-notch basement waterproofing solutions in Reedsport, ensuring your space stays dry, healthy, and functional, no matter the weather.
Crawl Space Repair Reedsport
Crawl spaces might not get much attention, but they’re essential for your home’s structure and air quality here in Reedsport. If left unattended, these areas can trap mold, pests, and standing water. Over time, this can result in wood rot, unpleasant odors, and even health problems for those living in the home.
We understand the crawl space conditions in Reedsport, OR, and TerraFirma’s crawl space repair services are tailored to combat moisture, mold, pests, and sagging floors with comprehensive encapsulation, effective drainage, and strong 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 Reedsport 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 Reedsport
Cracked, damaged, or uneven concrete isn’t just an eyesore; it can also pose safety risks. Issues like poor soil compaction, freeze-thaw cycles, erosion, and tree root growth can lead to these problems. Homeowners in Reedsport trust us to promptly and effectively repair their concrete slabs, sidewalks, patios, and driveways.
At TerraFirma in Reedsport, we provide quick, clean, and durable concrete leveling and repair solutions using state-of-the-art polyurethane foam injection and crack sealing techniques.

- 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.

- 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 Reedsport, OR for industrial buildings, warehouse floors, roads, runways, and rail lines—using the same high-quality systems we trust for residential properties.
Earthquake Retrofitting Reedsport, OR
Much of the Pacific Northwest, including Reedsport, sits in an active seismic zone. Homes constructed before the updated building codes of the 1990s are particularly at risk. Even a minor earthquake can lead to a house shifting off its foundation or suffering significant structural damage.
TerraFirma’s earthquake retrofitting services help secure your Reedsport home to its foundation and strengthen its ability to withstand seismic events.
Upgrading your home with earthquake retrofitting in Reedsport not only helps keep you safe but can also lower your insurance premiums and deductibles, plus make you eligible for coverage you might not have qualified for before.
How We Retrofit
Assessment & Planning
The retrofitting process starts with a thorough assessment of your building’s condition right here in Reedsport. A qualified expert, like a structural engineer or trained technician, will inspect your home to pinpoint any weaknesses and recommend the best solutions.
Our evaluation covers a thorough inspection of the foundation, walls, roof, and overall structure. Using these insights, our engineers create a detailed retrofitting plan tailored to your needs.
Foundation Bolting
Protecting your home starts with securing the foundation. Our technicians install anchor bolts to firmly attach your house to its foundation, helping to prevent movement during an earthquake.
This process involves drilling into the foundation and installing steel bolts. Our team then tightens these bolts to strengthen the structure, improving its stability and ability to withstand seismic activity.
Adding Shear Walls
Shear walls play a vital role in earthquake retrofitting by helping to distribute seismic forces and keep buildings in Reedsport standing strong.
Shear walls, usually made of plywood or other sturdy materials, are placed in key areas of homes, especially in cripple walls. They enhance the walls’ support and stability, helping to lower the chances of damage during an earthquake.
Bracing & Reinforcing
Next, we’ll strengthen key areas of your Reedsport home with durable steel braces and straps. Our team carefully installs these on essential structural elements like the roof, walls, and floors. This process enhances your home’s overall stability, giving it a solid framework that can better withstand seismic forces.
Securing Applicances
By securing your appliances, you can create a safer home for everyone in Reedsport. It’s important to anchor items like water heaters and refrigerators. Our technicians will also install safety measures for gas meters to help prevent any 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.
