Foundation Fixers is a Phoenix-based company that specializes in foundation repair. We're not a general contractor who happens to do foundation work on the side. This is what we do, every day, across the Valley.
Signs You Need Foundation Repair
- Cracks in drywall, especially around door frames and windows
- Doors or windows that stick or won't latch properly
- Visible cracks in the exterior block or stucco
- Uneven or sloping floors
- Gaps between the wall and ceiling or wall and floor
- The foundation itself has visible cracks
- Water pooling near the foundation after rain
How We Fix Foundations
Our primary method is polyurethane foam injection. We drill small, penny-sized holes through the slab and inject high-density foam into the void beneath your foundation. The foam expands, fills gaps in the soil, compacts loose material, and lifts the slab back toward level. It cures in about 15 minutes and is permanent. This is the fastest, least invasive, and most cost-effective foundation repair method available — and it handles the overwhelming majority of Phoenix-area foundation problems. Read the full process →
Foundation Fixers handles the full structural spectrum, not just slab lifts. Stem-wall repair on stucco homes (rebar corrosion, exterior block cracking), post-tension slab foundations common in 1990s and newer tract homes, and helical or push piers when the underlying soil cannot continue bearing the load — we assess the construction type before drilling and quote each scope specifically, and we coordinate with licensed structural engineers on complex cases.
If what's actually broken is flatwork — driveway, patio, pool deck, sidewalk, garage floor — that's not foundation work. We handle it on the same visit, but it's quoted under flatwork and slab repair rather than the foundation scope. See repair vs. replacement for the decision framework, or the method comparison if you've already had a mudjacking bid.
Why Foundations Fail in Phoenix
Phoenix sits on a mix of caliche, expansive clay, and sandy soil — sometimes all three in the same lot. The extreme heat (110°+ summers) dries soil and causes it to shrink away from foundations. Then monsoon season dumps water fast, causing rapid expansion. This cycle repeats year after year, and eventually something gives.
Add irrigation systems that slowly erode soil near foundations, plumbing leaks under slabs that wash out voids, and rapid development during the housing boom where compaction standards varied — and you've got a perfect recipe for foundation movement.
Foundation Repair Cost
Most residential foundation repairs in Phoenix range from $2,000 to $8,000 depending on the extent of the damage. Standard foam injection lifts and void-fill jobs are on the lower end. Larger and more complex projects sit higher. We provide free estimates with detailed pricing — no surprises.
