Foundation Repair Sisters
Foundation issues can lead to significant damage to your home if not taken care of. Signs like cracked floors, bowing walls, and sagging floors may indicate underlying structural problems. Residents in Sisters, OR might find that doors are sticking, windows aren’t closing right, or there are noticeable gaps between the walls and ceilings. These can be warning signs that your foundation is shifting due to soil movement, water damage, or the natural aging process.
At TerraFirma, we specialize in foundation repair right here in Sisters, OR, offering expert solutions designed specifically for the unique causes of your foundation issues. Our process starts with a thorough inspection to determine the extent and source of the problem. From there, we recommend one or more of our trusted foundation repair systems:
Foundation piers
In Sisters, OR, our push and helical piers are expertly designed to strengthen and lift your foundation by directing its weight to deeper, more stable soil. Helical piers work great in areas with predictable soil conditions, while push piers are ideal for spots where the soil stability might be uncertain. Both options are minimally invasive and provide 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 home here in Sisters.
Basement Waterproofing Sisters
Water in your basement can create serious problems like mold, mildew, structural damage, and poor air quality in your home. In Sisters, you might notice signs of water intrusion such as musty odors, stained walls, pooling water, or efflorescence, which is that white, powdery residue left when water evaporates. Remember, even a small crack in your basement wall can turn into a major entry point for unwanted moisture.
TerraFirma provides top-notch basement waterproofing solutions in Sisters, ensuring your space stays dry, healthy, and functional—come rain or shine.
Crawl Space Repair Sisters
Don’t underestimate the importance of your crawl space! In Sisters, OR, these often-overlooked areas are vital for maintaining your home’s structure and air quality. If left unattended, a crawl space can become a breeding ground for mold, pests, and standing water, leading to issues like wood rot, unpleasant odors, and potential respiratory problems for you and your family.
We’re familiar with the crawl space conditions in Sisters, OR, and TerraFirma’s crawl space repair services are tailored to tackle moisture, mold, pests, and sagging floors with full encapsulation, effective drainage, and solid 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 Sisters 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 Sisters
Cracked, damaged, or uneven concrete isn’t just an eyesore—it’s a safety concern too. Issues like poor soil compaction, freeze-thaw cycles, erosion, or tree root growth can lead to these problems. That’s why homeowners in Sisters turn to us for fast and effective repairs for their concrete slabs, sidewalks, patios, and driveways.
At TerraFirma, we provide quick, effective, and durable concrete leveling and repair services for Sisters, OR, using cutting-edge polyurethane foam injection and crack sealing techniques.
PolyLevel® Concrete Lifting
PolyLevel utilizes expanding polyurethane foam to elevate and stabilize concrete slabs. This non-invasive method 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.
We also provide commercial concrete repair in Sisters, OR for industrial buildings, warehouse floors, roads, runways, and rail lines—using the same high-quality systems we trust for residential properties.
Earthquake Retrofitting Sisters, OR
Sisters, OR, is located in a region prone to seismic activity, making it important for homeowners to be aware of the risks. Houses built before the 1990s, when updated building codes were put into place, might be more susceptible to damage. Even a small earthquake can cause a home to shift off its foundation or incur significant structural issues.
TerraFirma’s earthquake retrofitting services help secure your Sisters home to its foundation and strengthen its ability to withstand seismic events.
Retrofitting your home against earthquakes in Sisters can lead to lower insurance premiums and deductibles, plus it may even unlock coverage options that weren’t available before the upgrade.
How We Retrofit
Assessment & Planning
The retrofitting process starts with a thorough assessment of your building’s current condition. A professional, like a structural engineer or trained technician, will inspect your home to pinpoint any weaknesses and suggest the best solutions.
Our evaluation covers the foundation, walls, roof, and overall structure. After assessing these elements, our engineer will create a detailed retrofitting plan tailored to our findings.
Foundation Bolting
Securing the foundation is an essential next step. Our technicians install anchor bolts to firmly connect your home to its foundation, ensuring it stays stable and secure during an earthquake.
Our team drills into the foundation and installs steel bolts, tightening them to strengthen your home’s stability and improve its resistance to seismic forces. Rest assured, we’re here to help protect your Sisters, OR property!
Adding Shear Walls
Shear walls are an essential part of earthquake retrofitting in Sisters, OR, helping to distribute seismic forces and keep buildings safe from collapse.
Shear walls are usually made of plywood or other durable materials, and they’re strategically placed throughout your home, especially in the cripple walls. These additions offer extra support and stability, helping to minimize the risk of damage during an earthquake.
Bracing & Reinforcing
Next, our team enhances the critical areas of your home in Sisters with sturdy steel braces and straps. These are strategically installed on essential structural elements like the roof, walls, and floors. This step boosts your home’s overall stability, ensuring it has a robust framework that can stand up to seismic forces.
Securing Applicances
By securing your appliances, you can create a safer home for you and your loved ones in Sisters, OR. It’s important to anchor items like water heaters and refrigerators. Our technicians also offer installation of protective measures 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.

Sisters
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.
