Foundation Repair Kenmore
Don’t let foundation issues lead to serious damage to your home in Kenmore, WA. If you notice signs like cracked floors, bowing walls, or sagging floors, it may indicate deeper structural concerns. Homeowners here might also experience sticking doors, windows that won’t close right, or gaps between walls and ceilings—these could all point to a shifting foundation caused by soil movement, water damage, or simply the passage of time. Addressing these symptoms early can save you from costly repairs down the line.
At TerraFirma, we specialize in foundation repair right here in Kenmore. Our expert solutions are designed to address the specific causes of your foundation issues. We start with a thorough inspection to determine the extent and source of the problem, and then we recommend one or more of our trusted foundation repair systems tailored to your needs.
Foundation piers
In Kenmore, WA, our push and helical piers are expertly designed to stabilize and lift your foundation by redirecting its weight to deeper, more stable soil layers. Helical piers work best in areas with predictable soil conditions, while push piers are ideal for those with unknown soil stability. Both systems are minimally invasive, ensuring a permanent solution 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 professional installation, ongoing maintenance options, and transferable warranties, ensuring you have confidence and peace of mind in your Kenmore home.
Basement Waterproofing Kenmore
Dealing with a wet basement in Kenmore can result in mold, mildew, structural damage, and a decline in air quality throughout your home. Water intrusion might reveal itself through musty odors, stained walls, pooling water, or efflorescence—a white, powdery residue that appears when water evaporates. Even a tiny crack in your basement wall can turn into a significant gateway for moisture.
TerraFirma provides state-of-the-art basement waterproofing solutions in Kenmore that ensure your space stays dry, healthy, and functional—regardless of the weather.
Crawl Space Repair Kenmore
Don’t underestimate your crawl space! In Kenmore, WA, it’s an essential part of your home’s structure and air quality. If left neglected, your crawl space could become a breeding ground for mold, pests, and standing water, leading to wood damage, unpleasant odors, and even respiratory problems for your family. Keeping it in check is key to a healthy home!
At TerraFirma, we understand the unique crawl space conditions in Kenmore, WA. Our specialized crawl space repair services tackle moisture, mold, pests, and sagging floors with complete encapsulation, effective drainage solutions, 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 Kenmore 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 Kenmore
Damaged, cracked, or uneven concrete not only looks bad but can also be a safety issue. These problems often arise from poor soil compaction, freeze-thaw cycles, erosion, or tree roots. That’s why homeowners in Kenmore trust us to promptly and effectively repair their concrete slabs, sidewalks, patios, and driveways.
TerraFirma provides quick, efficient, and durable concrete leveling and repair services in Kenmore, WA, using state-of-the-art polyurethane foam injection and crack sealing.
PolyLevel® Concrete Lifting
PolyLevel utilizes expanding polyurethane foam to lift and stabilize concrete slabs. This non-invasive solution is perfect for Kenmore residents looking to fix uneven surfaces.
- 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 Kenmore, WA for industrial buildings, warehouse floors, roads, runways, and rail lines—using the same high-quality systems we trust for residential properties.
Earthquake Retrofitting Kenmore, WA
Kenmore, WA, is located in an active seismic zone, which means homes built before the updated building codes of the 1990s are particularly at risk. Even a small earthquake can lead to significant issues, such as a house shifting off its foundation or suffering serious structural damage.
TerraFirma’s earthquake retrofitting services help secure your Kenmore home to its foundation and strengthen its ability to withstand seismic events.
Getting your home retrofitted for earthquakes in Kenmore not only enhances safety but can also help lower your insurance premiums and deductibles, plus make you eligible for coverage options that weren’t available before the upgrade.
How We Retrofit
Assessment & Planning
In Kenmore, WA, the retrofitting process starts with a thorough assessment of your building’s current state. Our experts, including structural engineers and trained technicians, will inspect your home to pinpoint any weaknesses and suggest the best solutions.
This evaluation involves checking the foundation, walls, roof, and overall structure. After that, our engineer creates a detailed retrofitting plan tailored to the results.
Foundation Bolting
In Kenmore, securing your home’s foundation is a crucial next step. Our skilled technicians install anchor bolts to firmly connect your house to its foundation, keeping it stable and reducing lateral movement in the event of an earthquake.
In Kenmore, WA, we reinforce your home’s stability by drilling into the foundation and inserting steel bolts. Our expert team tightens these bolts to securely anchor the structure, improving its resilience against seismic forces.
Adding Shear Walls
Shear walls play an essential role in earthquake retrofitting in Kenmore, WA, helping to distribute seismic forces and keep buildings safe from collapsing.
In Kenmore, WA, shear walls are usually made of plywood or other durable materials, and our skilled professionals install them in key areas of your home, especially in cripple walls. These enhancements offer extra support and stability, helping to minimize the risk of damage during an earthquake.
Bracing & Reinforcing
Next, we reinforce key areas of your home in Kenmore with durable steel braces and straps. Our team installs these supports on essential features like the roof, walls, and floors. This crucial step enhances your home’s stability, ensuring it has a strong framework designed to withstand seismic activity.
Securing Applicances
Securing your appliances helps create a safer living space for everyone in your Kenmore home. It’s crucial to anchor items like water heaters and refrigerators. Our technicians also provide protection 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.

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.
