Foundation Repair Hoquiam
Foundation issues can lead to significant damage to your home if they’re not taken care of. In Hoquiam, WA, homeowners may notice signs like cracks in the floors, bowing walls, or sagging floors, which often indicate more serious structural problems. You might also find that your doors are sticking, your windows won’t close properly, or there are visible gaps between the walls and ceilings. These could all be indications that your foundation is shifting due to soil movement, water damage, or simply the effects of aging.
At TerraFirma, we’re dedicated to restoring foundations in Hoquiam with specialized solutions designed for your specific needs. Our process starts with a thorough inspection to identify the root cause and extent of your foundation issues. From there, we recommend one or more of our reliable foundation repair systems to ensure your home remains safe and stable.
Foundation piers
Our push and helical piers are designed to stabilize and lift your foundation by transferring its weight to deeper, more stable soil. Helical piers work great for known soil conditions, while push piers are the best choice for areas with uncertain soil stability. Both options are minimally invasive and provide permanent solutions for homes in Hoquiam.
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, reliable maintenance options, and transferable warranties, ensuring you have confidence and peace of mind in your home here in Hoquiam.
Basement Waterproofing Hoquiam
Dealing with a damp basement in Hoquiam, WA? It can lead to mold, mildew, structural issues, and poor air quality in your home. Signs of water intrusion may include 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 source of moisture.
TerraFirma provides top-notch basement waterproofing solutions in Hoquiam, ensuring your space stays dry, healthy, and functional—regardless of the weather.
Crawl Space Repair Hoquiam
Crawl spaces in Hoquiam are often overlooked, but they’re essential for your home’s structure and air quality. If neglected, these areas can become breeding grounds for mold, pests, and even standing water. This can lead to wood rot, unpleasant odors, and potential respiratory problems for everyone in the house.
We understand the unique crawl space conditions in Hoquiam, WA, and TerraFirma is here to help. Our crawl space repair services tackle moisture, mold, pests, and sagging floors with complete encapsulation, effective 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 Hoquiam 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 Hoquiam
Damaged, cracked, or uneven concrete isn’t just an eyesore—it can also pose safety risks. These issues often arise from factors like poor soil compaction, freeze-thaw cycles, erosion, or tree root growth. That’s why homeowners in Hoquiam trust us to swiftly and effectively repair their concrete slabs, sidewalks, patios, and driveways.
TerraFirma provides Hoquiam with quick, tidy, and durable concrete leveling and repair services, utilizing cutting-edge polyurethane foam injection and crack sealing.
PolyLevel® Concrete Lifting
PolyLevel employs expanding polyurethane foam to lift and stabilize concrete slabs. This non-invasive method is perfect for residents of Hoquiam, WA, looking to:
- 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

- Cures in just 60 minutes.
- Withstands extreme weather and heavy use.
- Includes color-matched sand for a clean, polished look.
SealantPro™ Concrete Protection

Earthquake Retrofitting Hoquiam, WA
Hoquiam, WA, is located in an active seismic zone, making it important for homeowners to stay informed. Homes constructed before the updated building codes of the 1990s may be particularly at risk. Even a small earthquake can lead to a house shifting off its foundation or suffering significant structural damage.
TerraFirma’s earthquake retrofitting services help secure your Hoquiam home to its foundation and strengthen its ability to withstand seismic events.
Earthquake retrofitting in Hoquiam not only helps protect your home but can also lower your insurance premiums and deductibles, making you eligible for coverage that may not have been available before the upgrade.
How We Retrofit
Assessment & Planning
In Hoquiam, WA, the retrofitting process starts with a thorough evaluation of your building’s current state. A qualified professional, like a structural engineer or skilled technician, will carefully inspect your home to pinpoint any weaknesses and suggest the best solutions.
Our evaluation looks closely at the foundation, walls, roof, and overall structure of your property. Following this assessment, our engineer will create a detailed retrofitting plan tailored to what we find.
Foundation Bolting
Securing the foundation is the next step in our process here in Hoquiam. Our technicians expertly install anchor bolts to firmly connect your home to its foundation, ensuring it stays stable and protected during an earthquake.
In this process, we drill holes into the foundation and insert sturdy steel bolts. Our skilled workers then tighten these bolts to reinforce the structure, boosting its stability and resilience against seismic forces right here in Hoquiam.
Adding Shear Walls
Shear walls play a vital role in earthquake retrofitting by helping to distribute seismic forces, ensuring that buildings in Hoquiam remain stable and safe during tremors.
Shear walls, made from plywood or other sturdy materials, are strategically placed throughout homes—especially in areas known as cripple walls. These reinforcements add crucial support and stability, helping to minimize the risk of damage during an earthquake in Hoquiam.
Bracing & Reinforcing
Next, we enhance the critical areas of your Hoquiam home with sturdy steel braces and straps. Our team installs these essential reinforcements on key structural elements like the roof, walls, and floors. This important step boosts your home’s stability, ensuring it has a resilient framework capable of withstanding seismic activity.
Securing Applicances
By securing your appliances, you can help create a safer living space for everyone in Hoquiam. Anchoring items like water heaters and refrigerators is crucial, and our technicians will also provide protection for gas meters 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.
