Foundation Repair Bainbridge Island
Foundation issues can lead to significant damage to your home if not taken care of. If you notice floor cracks, bowing walls, or sagging floors, it’s likely a sign of deeper structural problems. Residents of Bainbridge Island, WA, might experience doors that stick, windows that won’t close properly, or gaps appearing between walls and ceilings—all of which could indicate that your foundation is shifting due to soil movement, water damage, or the natural aging process of your home.
At TerraFirma, we specialize in foundation repairs right here on Bainbridge Island. Our expert team provides targeted solutions designed specifically for the unique challenges your foundation may face. We start with a thorough inspection to pinpoint the source and extent of the issue, and then we recommend one or more of our effective foundation repair systems tailored just for you.
Foundation piers
Our push and helical piers are designed to effectively stabilize and lift your foundation by transferring its weight to deeper, more stable soil. Helical piers work best in areas with known soil conditions, while push piers are perfect for regions where soil stability may be uncertain. Both systems are minimally invasive and provide lasting solutions for your home on Bainbridge Island.
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, options for ongoing maintenance, and transferable warranties, ensuring you feel confident and at ease in your Bainbridge Island home.
Basement Waterproofing Bainbridge Island
On Bainbridge Island, a wet basement can result in mold, mildew, structural issues, and poor air quality in your home. You might notice signs of water intrusion like musty odors, stained walls, puddles, or efflorescence—a white, powdery material left behind as water evaporates. Even a tiny crack in your basement wall can open the door to unwanted moisture.
TerraFirma provides top-notch basement waterproofing solutions right here in Bainbridge Island, ensuring your space stays dry, healthy, and functional—come rain or shine.
Crawl Space Repair Bainbridge Island
Crawl spaces are often forgotten, yet they play a vital role in the structure and air quality of your Bainbridge Island home. If left unattended, a neglected crawl space can become a breeding ground for mold, pests, and standing water. This can result in wood rot, unpleasant odors, and even health issues for your family.
We understand the unique crawl space conditions in Bainbridge Island, WA. That’s why TerraFirma offers tailored crawl space repair services 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 Bainbridge Island 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 Bainbridge Island
Damaged, cracked, or uneven concrete can be more than just an eyesore—it poses a safety risk too. These issues often arise from poor soil compaction, freeze-thaw cycles, erosion, or tree root growth. Residents of Bainbridge Island trust us to swiftly and effectively repair their concrete slabs, sidewalks, patios, and driveways.
TerraFirma provides quick, clean, and durable concrete leveling and repair solutions right here in Bainbridge Island, WA, using state-of-the-art polyurethane foam injection and crack sealing.
PolyLevel® Concrete Lifting
PolyLevel utilizes expanding polyurethane foam to raise and stabilize concrete slabs. This non-invasive method is perfect for Bainbridge Island homeowners looking to address:
- 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 Bainbridge Island, WA for industrial buildings, warehouse floors, roads, runways, and rail lines—using the same high-quality systems we trust for residential properties.
Earthquake Retrofitting Bainbridge Island, WA
Bainbridge Island is part of the Pacific Northwest, which is known for its seismic activity. Homes constructed before the updated building codes of the 1990s are particularly at risk. Even a small earthquake can lead to a home shifting off its foundation or suffering serious structural damage.
TerraFirma’s earthquake retrofitting services help secure your Bainbridge Island home to its foundation and strengthen its ability to withstand seismic events.
Retrofitting your home for earthquakes in Bainbridge Island not only enhances safety but can also help lower your insurance premiums and deductibles, and even open the door to coverage options that weren’t available before.
How We Retrofit
Assessment & Planning
The retrofitting process starts with a thorough assessment of your building’s current condition. A qualified expert, like a structural engineer or a trained technician, will inspect your home to pinpoint any weaknesses and suggest the best solutions for your needs.
This assessment involves inspecting the foundation, walls, roof, and overall structure. Following that, our engineer will create a detailed retrofitting plan tailored to the findings.
Foundation Bolting
Securing the foundation is the next important step. Our technicians install anchor bolts to firmly connect your home to its foundation, helping to prevent any shifting during an earthquake, especially for those of us here on Bainbridge Island.
Our process includes carefully drilling into the foundation and installing sturdy steel bolts. Our team then tightens these bolts to reinforce the structure, boosting its stability and resilience against seismic activity.
Adding Shear Walls
Shear walls play a vital role in earthquake retrofitting on Bainbridge Island, helping to distribute seismic forces and keeping buildings safe from collapse.
Shear walls are usually made from sturdy materials like plywood and are installed in key areas of your home, especially in cripple walls. These walls enhance support and stability, helping to minimize the risk of damage during an earthquake.
Bracing & Reinforcing
Next, our team will strengthen key areas of your home on Bainbridge Island using durable steel braces and straps. These are carefully installed on essential structural components like the roof, walls, and floors. This crucial step enhances your home’s overall stability, providing a robust framework designed to withstand seismic forces.
Securing Applicances
Securing your appliances helps create a safer living environment for everyone on Bainbridge Island. It’s crucial to anchor items like water heaters and refrigerators. Our technicians will also install safeguards 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.

Bainbridge Island
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.
