Foundation Repair by Legacy General Contractor

Foundation problems — cracks, settling, heaving, bowing walls — require professional diagnosis and repair. We provide foundation crack injection (epoxy and polyurethane), foundation leveling with piers or foam, underpinning for increased bearing capacity, slab lifting (mudjacking and polyurethane foam), and complete commercial foundation stabilization. Every repair starts with a thorough assessment to identify the root cause before recommending the right solution.

Why Choose Our Foundation Repair
Foundation repair requires accurate diagnosis before any work begins. We identify the root cause — settling, lateral pressure, water damage, frost heave — and recommend the most effective, cost-efficient solution.
Not every crack means your foundation is failing. We'll tell you honestly whether you need a $300 crack injection or a $15,000 stabilization project.
Our repair methods are proven and backed by manufacturer warranties. We use helical and push pier systems from leading manufacturers.
Signs You Need Foundation Repair
1. Cracks in foundation walls
Horizontal cracks, stair-step cracking in block walls, or widening vertical cracks indicate structural movement that needs professional evaluation.
2. Doors and windows sticking
When doors and windows become difficult to open or close, the frame may be shifting due to foundation movement.
3. Bowing or leaning basement walls
Inward bowing of basement walls from lateral soil pressure requires reinforcement before the wall fails.
4. Uneven or sloping floors
Floors that slope noticeably toward one direction indicate differential foundation settlement.

FAQs About Foundation Repair
How do I know if a foundation crack is serious?
Horizontal cracks, stair-step cracks in block, cracks wider than 1/4 inch, and cracks that are wider at one end than the other are potentially structural. Hairline vertical cracks are usually cosmetic shrinkage cracks. When in doubt, get a professional evaluation.
How much does foundation repair cost?
Costs range widely: simple crack injection runs $300-$800 per crack. Pier-based leveling runs $1,000-$3,000 per pier. Wall reinforcement runs $3,000-$15,000 depending on wall length. We provide free estimates with transparent pricing.
