Foundation Repair Algona
Foundation problems can lead to significant damage to your home if not addressed. In Algona, WA, homeowners may notice signs like cracks in the floors, bowing walls, and sagging floors, which could indicate more serious structural issues. You might also experience sticking doors, windows that won’t properly close, or noticeable gaps between walls and ceilings. These issues are often a sign that your foundation is shifting due to soil movement, water damage, or the effects of time.
At TerraFirma, we specialize in foundation repairs right here in Algona. Our expert solutions are designed to tackle the specific issues affecting your foundation. We start with a thorough inspection to pinpoint the extent and source of the problem, and then we recommend one or more of our proven foundation repair systems to get your home back on solid ground.
Foundation piers
In Algona, WA, our push and helical piers are designed to effectively stabilize and lift your foundation by transferring its weight to deeper, more stable soil layers. Helical piers work great for areas with known soil conditions, while push piers are perfect for locations where soil stability is uncertain. Both systems are minimally invasive and provide 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 professional installation, flexible maintenance options, and transferable warranties, ensuring you have confidence and peace of mind in your home in Algona.
Basement Waterproofing Algona
Dealing with a damp basement in Algona? It can lead to serious issues like mold, mildew, structural damage, and poor air quality in your home. You might notice 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 open the door for moisture problems.
TerraFirma provides top-notch basement waterproofing solutions right here in Algona, ensuring your space stays dry, healthy, and functional, no matter what the weather brings.
Crawl Space Repair Algona
Crawl spaces in Algona are often forgotten, yet they play a vital role in your home’s structure and air quality. If neglected, these areas can become a breeding ground for mold, pests, and standing water. These problems can lead to wood rot, unpleasant odors, and even respiratory issues for those living in your home.
At TerraFirma, we understand the unique crawl space challenges that homeowners in Algona, WA face. Our crawl space repair services are tailored to tackle moisture, mold, pests, and sagging floors, offering complete encapsulation, effective drainage solutions, 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.

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.

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 Algona, WA
Algona, WA, is part of an active seismic zone in the Pacific Northwest. Homes constructed before the updated building codes of the 1990s are particularly at risk. Even a small earthquake can cause significant issues, like shifting a home off its foundation or leading to serious structural damage.
TerraFirma’s earthquake retrofitting services help secure your Algona home to its foundation and strengthen its ability to withstand seismic events.
Retrofitting your home for earthquakes in Algona not only strengthens your property but can also lower your insurance premiums and deductibles, plus help you qualify for coverage options that were previously unavailable.
How We Retrofit
Assessment & Planning
The retrofitting process starts with a thorough evaluation of your building’s current condition. A qualified expert, like a structural engineer or trained technician, will inspect your home to pinpoint any weaknesses and suggest the best solutions for improvement.
This assessment involves a thorough inspection of the foundation, walls, roof, and overall structure. Following the evaluation, our engineer will create a detailed retrofitting plan tailored to the results.
Foundation Bolting
Securing the foundation is the next important step in our process. Our technicians expertly install anchor bolts to connect your home to its foundation, helping to prevent any lateral movement during an earthquake right here in Algona.
Our team carefully drills into the foundation and installs steel bolts, then tightens them to strengthen the structure. This process boosts stability and helps protect against seismic activity in Algona.
Adding Shear Walls
Shear walls are a vital part of earthquake retrofitting in Algona, WA. They help distribute seismic forces, keeping buildings safe and preventing collapses during an earthquake.
Shear walls are usually made from sturdy materials like plywood, and our skilled workers strategically install them in key areas throughout your home, especially in cripple walls. This extra support helps ensure your walls are stable and reduces the risk of damage during an earthquake right here in Algona.
Bracing & Reinforcing
Next, we strengthen key areas of your home in Algona with steel braces and straps. Our team expertly installs these reinforcements on critical structural elements like the roof, walls, and floors. This step enhances your home’s stability, ensuring it has a robust framework that can better withstand seismic forces.
Securing Applicances
Securing your appliances is key to creating a safer home for everyone in Algona, WA. Anchoring important items like water heaters and refrigerators is essential for peace of mind. Our technicians will also install protective measures for gas meters to help 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.
