Foundation repair in Greater Boston — engineered, warranted, mass.gov-licensed

Foundation repair in Boston is a high-stakes category — wet basements, settling cracks, and frost-heave damage to pre-1980 foundations create urgent homeowner demand. The Greater Boston water table sits high, and the seasonal hydrostatic pressure cycle drives more foundation cracks per capita than almost any other US metro.

Repair pricing ranges enormously by scope: a single non-structural crack injection runs $1,800-$3,500; multiple non-structural cracks with interior waterproofing $4,000-$8,000; structural crack with rebar augmentation $8,000-$18,000; full underpinning or section pour $18,000-$45,000.

The critical decision is method selection: hydraulic-cement injection for active water intrusion through small cracks; polyurethane injection for non-active leaks with movement potential; carbon-fiber straps for structural bowing without active leaks; full re-pour with rebar grid for severely compromised sections. Wrong method = $20K+ failure within 2-3 years.

Foundation Repair — common questions

How do I know if a crack is structural or cosmetic?
General rule: vertical cracks under 1/4 inch wide are usually non-structural (settling); horizontal cracks at any width are usually structural (lateral pressure or frost-heave); stair-step cracks in block foundations are usually structural. We do a free moisture-and-load assessment at the site visit and recommend the appropriate method.
Will my insurance cover foundation repair?
Insurance typically does not cover foundation repair from settling, age, or hydrostatic pressure (the most common causes). Insurance may cover foundation damage from a covered event (burst water main, vehicle impact, tree-fall). Peak does not work directly with insurance carriers on foundation claims — but we provide all documentation you need to submit your own claim if a covered event applies.
How long does foundation crack repair take?
Single non-structural crack injection: half-day on-site. Multiple cracks with interior waterproofing: 1-2 days on-site. Structural repair with rebar augmentation: 3-7 days. Full underpinning: 2-4 weeks. All include cure time and post-repair moisture monitoring.
Is the 5-year warranty really transferable?
Yes — Peak's 5-year foundation warranty transfers once to a subsequent home buyer at no cost. Many home buyers list "transferable foundation warranty" in their listing as a value-add. We register the warranty at project completion and provide the documentation packet for closing.
