Foundation Repair Lacey
Foundation problems can lead to significant damage if not dealt with in time. Homeowners in Lacey, WA may notice warning signs like cracks in the floors, bowing walls, or sagging floors, all of which could indicate more serious structural issues. You might find that your doors are sticking, windows won’t close easily, or that there are visible gaps between walls and ceilings. These symptoms can suggest that your foundation is shifting due to factors like soil movement, water damage, or simply the passage of time.
At TerraFirma, we provide expert foundation repair solutions in Lacey, WA, specifically designed to address the unique issues affecting your home. We start with a thorough inspection to determine the root cause and severity of your foundation concerns. From there, we recommend one or more of our effective foundation repair systems to restore your home’s stability.
Foundation piers
Our push and helical piers are designed to strengthen and elevate your foundation by anchoring it to deeper, more stable soil. Helical piers work great for areas with known soil conditions, while push piers are your go-to solution for unpredictable soil stability. Both options are minimally invasive and provide long-lasting support for your home in Lacey, WA.
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 have confidence and peace of mind in your home in Lacey.”
Basement Waterproofing Lacey
In Lacey, WA, a wet basement can create serious problems, from mold and mildew to structural damage and poor air quality throughout your home. You might notice signs of water intrusion like musty odors, stained walls, or pooling water. Efflorescence, a white, powdery residue left behind as water evaporates, may also be present. Even a tiny crack in your basement wall can turn into a significant entry point for moisture.
TerraFirma provides top-notch basement waterproofing solutions in Lacey, ensuring your space stays dry, healthy, and functional—regardless of the weather.
Crawl Space Repair Lacey
Crawl spaces are often forgotten, but they play a vital role in your home’s structure and air quality here in Lacey, WA. If left untended, a neglected crawl space can become a breeding ground for mold, pests, and standing water. These issues can result in wood rot, unpleasant odors, and even respiratory problems for your family.
We understand the unique crawl space challenges in Lacey, 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, drainage systems, and 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 Lacey 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.

Earthquake Retrofitting Lacey, WA
Lacey, WA, is located in a region of the Pacific Northwest that’s known for its seismic activity. Homes built before the updated building codes in the 1990s are particularly at risk. Even minor earthquakes can lead to significant issues, like shifting off foundations or serious structural damage.
TerraFirma’s earthquake retrofitting services help secure your Lacey home to its foundation and strengthen its ability to withstand seismic events.
Upgrading your home in Lacey, WA with earthquake retrofitting can help lower your insurance premiums and deductibles, plus you may qualify for coverage that wasn’t available before the upgrade.
How We Retrofit
Assessment & Planning
In Lacey, WA, the retrofitting process starts with a thorough evaluation of your building’s current state. Our team of experts, including experienced structural engineers and trained technicians, will carefully inspect your home to pinpoint any weaknesses and suggest the best solutions.
This evaluation covers the foundation, walls, roof, and overall structure of your property here in Lacey, WA. After the assessment, our engineer will create a detailed retrofitting plan tailored to the findings.
Foundation Bolting
Securing the foundation is the next important step in the process. Our technicians install anchor bolts to firmly connect your home to its foundation, ensuring stability and preventing any movement during an earthquake.
Our process begins by drilling holes into the foundation and inserting sturdy steel bolts. Our team then tightens these bolts to reinforce the structure, boosting its stability and resistance to seismic activity—ensuring your home in Lacey, WA, is safe and secure.
Adding Shear Walls
Shear walls play a vital role in earthquake retrofitting by helping to distribute seismic forces, ensuring that buildings in Lacey, WA, remain safe and sturdy during tremors.
Shear walls, made from durable materials like plywood, are installed at key points in homes, especially in areas known as cripple walls. They add extra support and stability to the structure, helping to minimize the risk of damage during an earthquake here in Lacey, WA.
Bracing & Reinforcing
Next, we enhance the critical areas of your Lacey home with sturdy steel braces and straps. Our team installs these reinforcements on key structural elements like the roof, walls, and floors. This vital step boosts your home’s overall stability, creating a solid framework designed to withstand seismic forces.
Securing Applicances
Ensuring your appliances are securely anchored helps create a safer living environment in Lacey. It’s important to secure items like water heaters and refrigerators. Our technicians can also install protective measures 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.
