Foundation Repair Kirkland
Foundation issues can lead to significant damage to your home if not taken care of promptly. Homeowners in Kirkland, WA may notice signs such as cracks in the floors, bowing walls, and sagging floors, which often point to more serious structural problems. You might find that doors are sticking, windows won’t close properly, or there are visible gaps between your walls and ceilings. These issues could signal that your foundation is shifting due to soil movement, water damage, or simply the effects of aging.
At TerraFirma, we provide expert foundation repair solutions right here in Kirkland, designed to address the specific issues affecting your home. Our process starts with a thorough inspection to identify the root cause and extent of the problem. From there, we’ll recommend one or more of our trusted foundation repair systems:
Foundation piers
In Kirkland, our push and helical piers are expertly designed to stabilize and lift your foundation by transferring its weight to more stable, deeper soil. Helical piers work best in areas with known soil conditions, while push piers are perfect for spots with uncertain soil stability. Both systems are minimally invasive and provide long-lasting solutions.
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 have confidence and peace of mind in your Kirkland home.
Basement Waterproofing Kirkland
Don’t let a wet basement put your Kirkland home at risk for mold, mildew, structural issues, and poor air quality. Signs of water intrusion can manifest as musty odors, stained walls, pooling water, or efflorescence—a powdery residue that appears when water evaporates. Even a tiny crack in your basement wall can turn into a significant entry point for moisture. Keep your home dry and safe!
TerraFirma provides top-notch basement waterproofing solutions in Kirkland, ensuring your space stays dry, healthy, and functional—rain or shine.
Crawl Space Repair Kirkland
Crawl spaces in Kirkland often get ignored, but they’re essential for your home’s structure and air quality. If left unattended, a neglected crawl space can become a breeding ground for mold, pests, and standing water. These issues can lead to wood rot, unpleasant odors, and even respiratory problems for you and your family.
We understand the unique crawl space challenges in Kirkland, WA. That’s why TerraFirma offers tailored crawl space repair services to tackle moisture, mold, pests, and sagging floors with our comprehensive solutions, including full encapsulation, effective drainage, and dependable 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 Kirkland 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 Kirkland
Damaged, cracked, or uneven concrete isn’t just an eyesore—it’s also a safety concern. These issues can arise from poor soil compaction, freeze-thaw cycles, erosion, or even tree roots. Residents of Kirkland trust us to promptly and effectively repair their concrete slabs, sidewalks, patios, and driveways.
TerraFirma provides Kirkland residents with quick, clean, and durable concrete leveling and repair services, utilizing cutting-edge polyurethane foam injection and crack sealing techniques.
PolyLevel® Concrete Lifting
PolyLevel utilizes expanding polyurethane foam to lift and stabilize concrete slabs. This non-invasive method is perfect for the needs of Kirkland residents, including:
- 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 Kirkland, WA for industrial buildings, warehouse floors, roads, runways, and rail lines—using the same high-quality systems we trust for residential properties.
Earthquake Retrofitting Kirkland, WA
Kirkland, WA, is located in an active seismic zone, and homes built before the updated building codes of the 1990s may be at greater risk. Even a minor earthquake can lead to significant issues, such as shifting off its foundation or sustaining serious structural damage.
TerraFirma’s earthquake retrofitting services help secure your Kirkland home to its foundation and strengthen its ability to withstand seismic events.
Earthquake retrofitting in Kirkland not only strengthens your home but can also lower your insurance premiums and deductibles, potentially qualifying you for coverage that wasn’t available before the upgrade.
How We Retrofit
Assessment & Planning
In Kirkland, the retrofitting process starts with a thorough assessment of your building’s current condition. Our qualified experts, including structural engineers and trained technicians, will carefully inspect your home to pinpoint any weaknesses and suggest the best solutions.
Our evaluation covers a thorough inspection of the foundation, walls, roof, and overall structure. From there, our engineer will create a detailed retrofitting plan tailored to the findings.
Foundation Bolting
Securing the foundation is the next step in the process. Our technicians install anchor bolts to firmly connect your home to its foundation, helping to prevent any lateral movement during an earthquake — a crucial safety measure for residents of Kirkland.
Our process includes drilling into the foundation and installing steel bolts. Our team then tightens these bolts to strengthen the structure, boosting its stability and resistance to seismic forces.
Adding Shear Walls
Shear walls play a vital role in earthquake retrofitting by helping to distribute seismic forces and protect your home from collapsing in the event of an earthquake.
Shear walls, often made from plywood or other durable materials, are installed in key areas of homes, especially in cripple walls. They offer added support and stability to the structure, helping to minimize the risk of damage during an earthquake—a key consideration for residents in Kirkland, WA.
Bracing & Reinforcing
Next, our team reinforces essential areas of your Kirkland home with sturdy steel braces and straps. These are carefully installed on key structural components like the roof, walls, and floors. This crucial step enhances your home’s stability, providing a robust framework designed to withstand seismic activity.
Securing Applicances
By securing your appliances, you can create a safer living environment in Kirkland. It’s essential to anchor items like water heaters and refrigerators. Our technicians will also install protective measures for gas meters to help 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.
