Foundation Repair Edgewood
Foundation problems can lead to significant damage to your home if not taken care of. In Edgewood, WA, keep an eye out for signs like cracks in the floors, bowing walls, and sagging floors, as these often indicate more serious structural issues. Homeowners may also notice sticking doors, windows that won’t close right, or gaps appearing between walls and ceilings. These could all be signs that your foundation is shifting due to soil movement, water damage, or simply the aging of your home.
At TerraFirma, we’re proud to offer specialized foundation repair services right here in Edgewood. Our expert team understands that each foundation issue is unique, which is why we start with a thorough inspection to pinpoint the root cause of your foundation problems. From there, we present tailored solutions using our proven foundation repair systems:
Foundation piers
Our push and helical piers are specifically designed to stabilize and lift foundations by transferring their weight to deeper, more stable soil here in Edgewood, WA. Helical piers work great in areas with known soil conditions, while push piers are the go-to choice for locations with uncertain soil stability. Both options are minimally invasive and provide lasting solutions for your foundation issues.
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 Edgewood home.
Basement Waterproofing Edgewood
Experiencing a wet basement in Edgewood, WA? It can result in mold, mildew, structural damage, and even affect the air quality in your home. You might notice musty odors, stained walls, standing water, or efflorescence—a white, powdery substance that appears when water evaporates. 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 Edgewood, ensuring your space stays dry, healthy, and functional—come rain or shine.
Crawl Space Repair Edgewood
Don’t forget about your crawl space—it’s a vital part of your home’s structure and air quality here in Edgewood, WA. If left unattended, a neglected crawl space could become a breeding ground for mold, pests, and standing water. These issues can lead to wood rot, unpleasant odors, and even health problems for you and your family.
We understand the unique crawl space issues in Edgewood, WA. That’s why TerraFirma offers specialized crawl space repair services tailored to tackle moisture, mold, pests, and sagging floors with solutions like full encapsulation, reliable drainage, and sturdy 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 Edgewood 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 Edgewood
Damaged, cracked, or uneven concrete isn’t just an eyesore—it can be a safety risk. These issues often arise from poor soil compaction, freeze-thaw cycles, erosion, or tree root growth. That’s why homeowners in Edgewood trust us to quickly and effectively restore their concrete slabs, sidewalks, patios, and driveways.
TerraFirma provides quick, efficient, and durable concrete leveling and repair solutions right here in Edgewood, WA, utilizing cutting-edge polyurethane foam injection and expert crack sealing.

Earthquake Retrofitting Edgewood, WA
Edgewood is nestled in an active seismic zone of the Pacific Northwest. Homes constructed before the updated building codes of the 1990s can be particularly at risk. Even a small earthquake could cause a home to shift off its foundation or suffer significant structural damage.
TerraFirma’s earthquake retrofitting services help secure your Edgewood home to its foundation and strengthen its ability to withstand seismic events.
Earthquake retrofitting in Edgewood not only strengthens your home but can also lower your insurance premiums and deductibles, as well as help you qualify for coverage that may not have been available before.
How We Retrofit
Assessment & Planning
In Edgewood, WA, the retrofitting process starts with a thorough assessment of your building’s current condition. Our experts, including structural engineers and trained technicians, will inspect your home to pinpoint any weaknesses and suggest the best solutions.
This evaluation looks at the foundation, walls, roof, and overall structure of your home here in Edgewood, WA. Following this assessment, our engineer will create a detailed retrofitting plan tailored to your specific needs.
Foundation Bolting
In Edgewood, WA, securing your home’s foundation is the crucial next step. Our technicians install anchor bolts to firmly connect your house to its foundation, ensuring stability and preventing any lateral movement during an earthquake.
Our process includes drilling into the foundation and inserting steel bolts, which are then tightened to reinforce the structure. This helps enhance its stability and resistance to seismic forces, ensuring your safety in Edgewood, WA.
Adding Shear Walls
Shear walls are a vital part of earthquake retrofitting in Edgewood, WA, helping to distribute seismic forces and keeping buildings safe from collapse.
In Edgewood, WA, shear walls are typically made from plywood or other durable materials. Skilled workers strategically install these walls throughout your home, especially in areas like cripple walls. This added support enhances the stability of your home, significantly lowering the risk of damage during an earthquake.
Bracing & Reinforcing
Next, we enhance the critical areas of your Edgewood home by installing steel braces and straps. Our team secures these to essential structural elements like the roof, walls, and floors. This important step boosts your home’s stability, creating a strong framework designed to withstand seismic forces.
Securing Applicances
Ensuring your appliances are secure can help create a safer living environment in Edgewood, WA. Anchoring key items like water heaters and refrigerators is essential for your home’s safety. Our technicians will 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.
