With years of hands-on experience, advanced repair techniques, and a commitment to lasting results, we’ve built a strong reputation for quality, reliability, and customer satisfaction.

Homeowners across Seattle trust us for honest assessments, fair pricing, and work that stands the test of time.
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.
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.
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.
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.
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.
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.
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.

At Greater Seattle Roofing & Construction, we follow a thorough, step-by-step foundation repair process to ensure the job is done right the first time. From the initial inspection to the final walkthrough, we’re committed to transparency, precision, and long-lasting results. Here’s how we restore safety and stability to your home:
Every project starts with a no-obligation inspection by one of our experienced foundation specialists. We assess visible signs of damage—such as cracks, sloping floors, water intrusion, or settling—and use tools like laser levels and moisture meters to evaluate the severity and root cause of the problem.
Once we identify the issue, we create a detailed repair plan tailored to your home’s specific foundation type, soil conditions, and structural needs. Whether it’s pier installation, wall reinforcement, or waterproofing, we explain your options clearly and walk you through the recommended solution.
If permits are required, we take care of all the paperwork to ensure compliance with local building codes. We also prepare the work area by protecting landscaping, interior surfaces, and entryways to minimize disruption during the repair process.
Our trained technicians use industry-leading equipment and proven methods—such as helical piers, wall anchors, carbon fiber strips, or drainage systems—to restore structural integrity. We work efficiently and with precision, ensuring every repair meets our strict quality and safety standards.
After the repair is complete, we thoroughly clean the job site and restore any disturbed areas. A final inspection is conducted to confirm the work has been completed to code and that the problem has been fully addressed. We also provide documentation for insurance, resale, or peace of mind.
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 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.
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.
Our commitment to foundation repair is unwavering, and we won’t rest until our customers are completely satisfied with the outcome. With us, your satisfaction is not just a goal; it’s a guarantee.

The cost of foundation repair in Seattle varies depending on the type and extent of the damage, soil conditions, and the repair methods required. Minor repairs like sealing small cracks or installing carbon fiber reinforcements typically range from $1,000 to $3,000, while more extensive repairs such as foundation leveling with helical piers or full wall stabilization can cost between $5,000 and $15,000 or more. Factors like accessibility, the size of the home, and necessary permits also influence pricing. Because each home’s foundation is unique, we recommend a professional inspection to provide an accurate estimate tailored to your specific needs. Investing in quality foundation repair protects your home’s structural integrity and can save you from far more costly problems down the road.
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.
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.
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.
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.
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.
