Foundation Repair Poulsbo
Foundation problems can lead to significant damage to your home if not taken care of promptly. In Poulsbo, WA, homeowners may observe signs such as cracks in the floors, bowing walls, or sagging floors — all of which could indicate deeper structural issues. You might also notice doors that stick, windows that won’t close right, or gaps developing between your walls and ceilings. These issues could be a sign that your foundation is shifting due to soil movement, water damage, or the natural aging of your home.
At TerraFirma, we provide expert foundation repair solutions right here in Poulsbo. Our first step is a thorough inspection to identify the source and extent of your foundation issues. From there, we recommend tailored solutions that effectively address your specific needs. Trust us to restore the stability of your home with our proven foundation repair systems.
Foundation piers
Introducing our advanced push and helical piers, specifically designed to stabilize and lift your foundation by shifting its weight to deeper, more stable soil. Helical piers are great for areas with known soil conditions, while push piers work best in spots where soil stability is uncertain. Both options are minimally invasive and provide long-lasting solutions right here in Poulsbo, 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 professional installation, flexible maintenance options, and transferable warranties, ensuring you feel confident and at ease in your Poulsbo home.
Basement Waterproofing Poulsbo
Living in Poulsbo, WA, you know that a wet basement can lead to serious issues like mold, mildew, structural damage, and poor air quality in your home. Look out for signs of water intrusion such as musty odors, stained walls, pooling water, or efflorescence—a white, powdery residue left behind when water evaporates. Even a tiny crack in your basement wall can turn into a major gateway for moisture.
At TerraFirma, we provide cutting-edge basement waterproofing solutions in Poulsbo that ensure your space stays dry, healthy, and functional—whatever the weather brings.
Crawl Space Repair Poulsbo
Crawl spaces in Poulsbo are often forgotten, yet they play a vital role in your home’s structure and air quality. If left unattended, 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 you and your family.
At TerraFirma, we understand the unique crawl space challenges faced in Poulsbo, WA. Our crawl space repair services are tailored to tackle moisture, mold, pests, and sagging floors with comprehensive solutions like full encapsulation, effective drainage, and reliable 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 Poulsbo 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 Poulsbo
Cracked, uneven, or damaged concrete is more than just an eyesore—it poses a safety risk. Issues like poor soil compaction, freeze-thaw cycles, erosion, and tree root growth can contribute to these problems. That’s why homeowners in Poulsbo trust us to swiftly and effectively repair their concrete slabs, sidewalks, patios, and driveways.
TerraFirma provides fast, efficient, and durable concrete leveling and repair services right here in Poulsbo, WA, using state-of-the-art polyurethane foam injection and expert crack sealing.

- 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.

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

We also provide commercial concrete repair in Poulsbo, WA for industrial buildings, warehouse floors, roads, runways, and rail lines—using the same high-quality systems we trust for residential properties.
Earthquake Retrofitting Poulsbo, WA
Poulsbo, WA, is located in an area that experiences seismic activity. Homes constructed before the updated building codes of the 1990s may be particularly at risk. Even a small earthquake can lead to a home shifting off its foundation or suffering significant structural damage.
TerraFirma’s earthquake retrofitting services help secure your Poulsbo home to its foundation and strengthen its ability to withstand seismic events.
Retrofitting your home for earthquakes in Poulsbo not only enhances safety but can also lower your insurance premiums and deductibles, plus help you qualify for coverage that may not have been available before the upgrade.
How We Retrofit
Assessment & Planning
The retrofitting process in Poulsbo starts with a thorough assessment of your building’s current condition. A qualified expert, like a structural engineer or a trained technician, will inspect your home to pinpoint any weaknesses and suggest the best solutions.
This assessment looks at the foundation, walls, roof, and overall structure of your property. Afterward, our engineer will create a detailed retrofitting plan tailored to the findings.
Foundation Bolting
Securing the foundation is the next step in ensuring your home’s safety here in Poulsbo. Our technicians expertly install anchor bolts to firmly connect your house to its foundation, guarding against lateral movement during an earthquake.
In Poulsbo, WA, we reinforce your building by drilling holes into the foundation and inserting steel bolts. Our team then tightens these bolts to ensure your structure is secure, boosting its stability and ability to withstand seismic activity.
Adding Shear Walls
Shear walls play a vital role in earthquake retrofitting by helping to distribute seismic forces, ensuring that buildings in Poulsbo remain safe and stable during an earthquake.
Shear walls, made from durable materials like plywood, are installed in key areas of homes, especially in cripple walls. These walls enhance stability and support, helping to protect your home and reduce the risk of damage during an earthquake—a vital feature for homeowners in Poulsbo, WA.
Bracing & Reinforcing
Next, we’ll strengthen vital areas of your Poulsbo home using durable steel braces and straps. Our team expertly installs these reinforcements on essential structural elements like the roof, walls, and floors. This crucial step enhances your home’s overall stability, ensuring it has a strong framework designed to withstand seismic forces.
Securing Applicances
Securing your appliances can help create a safer home for everyone in Poulsbo, WA. It’s important to anchor items like water heaters and refrigerators. Our technicians are also here to install safeguards for gas meters, reducing 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.
