Foundation Repair Aberdeen
Foundation problems can lead to significant damage to your home if they’re not taken care of. In Aberdeen, WA, you might see signs like cracks in your floors, bowing walls, or sagging floors, all of which can indicate more serious structural issues. Homeowners may also notice doors that stick, windows that won’t shut properly, or gaps between the walls and ceilings. These symptoms could mean your foundation is shifting due to soil movement, water damage, or natural wear and tear over time.
At TerraFirma, we specialize in foundation repair in Aberdeen, WA, offering expert solutions that address the root causes of your foundation issues. Our process starts with a thorough inspection to understand the extent and source of the problem. From there, we recommend one or more of our trusted foundation repair systems to get your home back on solid ground.
Foundation piers
Our push and helical piers are expertly designed to stabilize and lift your foundation by transferring its weight to deeper, more stable soil. In Aberdeen, WA, helical piers are a great choice for known soil conditions, while push piers work best in areas with uncertain soil stability. Both systems are minimally invasive, providing you with a lasting 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 home here in Aberdeen.
Basement Waterproofing Aberdeen
Having a damp basement in Aberdeen can create problems like mold, mildew, structural damage, and bad air quality in your home. You might notice signs of water intrusion such as musty odors, stained walls, standing 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 entry point for moisture.
TerraFirma provides cutting-edge basement waterproofing solutions in Aberdeen, ensuring your space stays dry, healthy, and functional—come rain or shine.
Crawl Space Repair Aberdeen
Crawl spaces in Aberdeen may easily be overlooked, but they play a vital role in your home’s structure and air quality. If left unattended, these areas can become a breeding ground for mold, pests, and standing water. Neglecting them can result in wood rot, unpleasant odors, and even respiratory problems for you and your family.
We understand the unique crawl space conditions in Aberdeen, WA. That’s why TerraFirma offers tailored crawl space repair services that effectively tackle moisture, mold, pests, and sagging floors with complete encapsulation, drainage solutions, and robust 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 Aberdeen 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 Aberdeen
Cracked, damaged, or uneven concrete isn’t just an eyesore—it’s a safety concern. These issues can arise from factors like poor soil compaction, freeze-thaw cycles, erosion, or tree root growth. Residents of Aberdeen count on us for quick and effective solutions to restore their concrete slabs, sidewalks, patios, and driveways.
TerraFirma provides quick, efficient, and durable concrete leveling and repair services in Aberdeen, WA, utilizing state-of-the-art polyurethane foam injection and crack sealing techniques.

Earthquake Retrofitting Aberdeen, WA
Aberdeen, WA, is situated in an active seismic zone, making it crucial for homeowners to be aware of potential risks. Homes built before the 1990s may not meet today’s updated building codes, leaving them especially vulnerable. Even a minor earthquake can lead to significant structural damage or cause a home to shift off its foundation.
TerraFirma’s earthquake retrofitting services help secure your Aberdeen home to its foundation and strengthen its ability to withstand seismic events.
Earthquake retrofitting in Aberdeen can help lower your insurance premiums and deductibles, plus it may even make you eligible for coverage options that weren’t available before the upgrade.
How We Retrofit
Assessment & Planning
The retrofitting process kicks off with a thorough assessment of your building’s current condition. A qualified expert, like a structural engineer or trained technician, will inspect your home in Aberdeen to pinpoint any weaknesses and suggest the best solutions.
This assessment involves examining the foundation, walls, roof, and overall structure. After that, our engineer will create a detailed retrofitting plan based on what we’ve discovered.
Foundation Bolting
Sealing the foundation is the next vital step in this process. Our technicians carefully install anchor bolts to firmly connect your home to its foundation, ensuring stability and preventing any lateral movement during an earthquake here in Aberdeen.
Our process starts by drilling into the foundation and inserting sturdy steel bolts. Our team then tightens these bolts to strengthen the structure, improving its stability and resilience against seismic activity.
Adding Shear Walls
Shear walls play an essential role in earthquake retrofitting, helping to distribute seismic forces and keeping buildings in Aberdeen, WA, safe from collapse.
In Aberdeen, WA, shear walls are usually made from plywood or other durable materials, strategically placed in key areas of your home, especially in cripple walls. These shear walls enhance the support and stability of your home, helping to reduce the risk of damage during an earthquake.
Bracing & Reinforcing
Next, we fortify key areas of your home in Aberdeen with steel braces and straps. Our team carefully installs these on essential structural components like the roof, walls, and floors. This process enhances your home’s stability, creating a strong framework designed to endure seismic activity.
Securing Applicances
Ensuring your appliances are secured creates a safer living space for everyone in Aberdeen, WA. It’s crucial to anchor items like water heaters and refrigerators. Our skilled technicians can also install protective measures for gas meters, helping to minimize 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.
