Fully-equipped to handle all kinds of foundation Services in Seattle

Before foundation repair, many homeowners experience a range of unsettling problems—cracks in walls or floors, uneven or sloping floors, sticking doors and windows, and even water intrusion in basements or crawl spaces. These issues often point to structural instability caused by settling soil, hydrostatic pressure, or aging construction. Left untreated, the damage can worsen, affecting not just your home’s safety but also its value.

After professional foundation repair, the transformation is significant. Cracks are sealed, walls are stabilized, and sunken sections are lifted back into place. Floors become level, doors and windows open smoothly, and moisture problems are resolved with proper drainage or waterproofing systems. Our team uses advanced tools and techniques—like steel piers, wall anchors, and waterproofing systems—to ensure long-term stability. The result is a safer, stronger home and peace of mind knowing your foundation is secure for years to come.

Foundation Crack Repair

Cracks in your foundation walls or floors can indicate everything from normal settling to serious structural shifts. We assess the size, cause, and severity of each crack and use high-quality epoxy or polyurethane injection systems to seal them permanently—preventing water infiltration and further deterioration.

Foundation Wall Stabilization

Bowing, bulging, or leaning basement walls are signs of pressure from surrounding soil. We offer proven wall stabilization systems such as steel I-beams, carbon fiber strips, and wall anchors to reinforce and realign foundation walls, restoring structural integrity and preventing future movement.

Foundation Settling & Sinking Solutions

If parts of your home feel uneven or you’re noticing gaps between walls and ceilings, it could be due to foundation settlement. Using helical piers or push piers, we stabilize and lift sunken sections of your home’s foundation—leveling floors and correcting structural shifts caused by unstable soil or poor drainage.

Basement Waterproofing

Water in your basement is often a sign of foundation weakness. We offer comprehensive waterproofing systems including interior drainage channels, sump pump installation, vapor barriers, and exterior grading improvements to keep your basement dry and your foundation protected year-round.

Crawl Space Support & Repair

Weak or sagging floors above crawl spaces are often the result of deteriorated or undersized support beams. We install adjustable steel support posts and supplemental framing to stabilize crawl spaces and correct floor bounce or slope—improving both safety and home value.

Concrete Slab Repair

Uneven or cracked concrete slabs in your basement, garage, or crawl space can affect the entire structure. We use slab jacking or polyurethane foam injection (slab lifting) to level and restore these surfaces without the need for full demolition.

Over 1000+ Happy Clients Trust Our Process

"I rarely write reviews, but I felt compelled to after the exceptional experience we had with Greater Seattle. From the very first phone call, their professionalism and knowledge stood out. We had been dealing with several concerning issues—cracks in our drywall, uneven floors, and a musty smell coming from the basement. After getting conflicting opinions from other contractors, we reached out for one more estimate, and I’m so glad we did. Their inspector arrived right on time and took his time walking through the entire house, inside and out. He didn’t just give a quick quote—he explained exactly what was happening with our foundation, why certain cracks were forming, and how the settling was affecting our structure. He used laser levels, moisture meters, and showed us photos of what was going on beneath the surface. The honesty and clarity were refreshing—no scare tactics or pressure sales, just straightforward facts and recommendations. Once we agreed to move forward, the crew was scheduled within a week. They showed up early every day, worked diligently, and were incredibly respectful of our property. They installed steel piers to stabilize the foundation and reinforced one of the basement walls with carbon fiber strips. The work area was kept clean and organized throughout the project, and they even went above and beyond by resealing a crawl space vent that wasn’t part of the original scope. After the work was complete, they walked us through everything they had done and showed us before-and-after photos. The cracks in the walls have stopped growing, doors that used to stick now open smoothly, and our basement has stayed dry—even during heavy Seattle rainstorms. Best of all, the peace of mind knowing our home is safe and secure is priceless. This company truly deserves its reputation as one of the best foundation repair specialists in the area. Honest, hardworking, and highly skilled—I wouldn’t hesitate to recommend them to anyone facing structural issues. Five stars all the way!"

Effective Foundation Repair Solutions for a Strong, Stable Home

Proven Methods to Fix Settling, Bowing Walls, and Basement Water Problems

Helical Pier Installation

Helical piers are steel shafts with helical (screw-like) plates that are drilled deep into stable soil layers beneath the foundation. Once anchored, these piers transfer the home’s weight to the load-bearing soil, lifting and stabilizing the structure.

Carbon Fiber Wall Reinforcement

Carbon fiber strips are applied directly to the inside surface of the foundation wall. Once bonded with industrial epoxy, they form a permanent barrier that stops further movement and reinforces the wall without extensive excavation.

Interior Drainage System with Sump Pump

An interior drainage system collects water from along the perimeter of the basement and directs it into a sump pump basin. The sump pump then actively pumps the water away from the home, keeping the basement dry.

Why Foundation Repair Matters

We Offer Customized Foundation Repair Services

Foundation repair is essential because your home’s foundation supports the entire structure, and any damage—whether cracks, settling, or shifting—can seriously compromise your home’s safety and stability. Delaying repairs can lead to worsening structural problems like uneven floors, bowed walls, or even partial collapse, putting your family at risk. Beyond safety, foundation issues significantly impact your home’s resale value, as buyers are often wary of expensive repairs that may be needed, which can stall or reduce offers. Moisture intrusion through foundation cracks creates damp environments that promote mold and mildew growth, damaging your property and potentially causing health issues. Additionally, foundation gaps allow warm or cool air to escape, reducing your home’s energy efficiency and raising utility bills. These openings also become entry points for pests like rodents and termites, which can further damage your home and create an unhealthy living space. Addressing foundation problems promptly protects your investment, enhances comfort, and ensures a safe, healthy environment for you and your family.

Structural Safety

Your foundation is the base that supports your entire home. Cracks, settling, or shifting weaken this support system and can compromise the structural integrity of walls, floors, and roofs. If left unrepaired, foundation damage can lead to uneven floors, wall bowing, or even partial structural failure—posing safety risks to you and your family.

Home Resale Value

Foundation problems are one of the top concerns for potential homebuyers and can drastically reduce your property’s market value. Homes with known foundation issues often fail inspections, leading to lower offers or requiring costly repairs before closing. Promptly addressing foundation repairs preserves and often increases your home’s resale value.

Moisture and Mold Issues

Cracks and gaps in the foundation allow water to seep into basements and crawl spaces, creating damp environments that promote mold and mildew growth. Moisture intrusion not only damages building materials but also affects indoor air quality, potentially causing health problems such as allergies or respiratory issues.

Signs You Need Foundation Repair

  • Visible Cracks in Walls or Floors
    Look for cracks wider than a quarter-inch or stair-step patterns in brickwork and mortar joints, both inside and outside your home.

  • Uneven or Sloping Floors
    Noticeable dips or slopes in your flooring that cause doors and windows to stick or not close properly are a strong indicator of foundation movement.

  • Gaps Around Doors and Windows
    Spaces between window or door frames and the walls can signal that your foundation is shifting or settling unevenly.

  • Water Seepage or Dampness in Basements or Crawl Spaces
    Moisture intrusion often results from foundation cracks, leading to damp walls, musty odors, or even mold growth.

  • Bowing or Leaning Basement Walls
    Walls that appear to curve inward or lean are typically caused by pressure from saturated soil pushing against the foundation.

  • Sticking Doors or Windows
    Doors or windows that suddenly become difficult to open or close may be due to foundation settling affecting the frame alignment.

  • Unusual Noises or Sounds
    Creaking, popping, or cracking noises inside the home can be a sign of structural stress as the foundation shifts.
