Foundation Repair in Buffalo, NY

Horizontal cracks in block or poured walls are the most serious, as they indicate lateral pressure from soil or frost heave. Diagonal stair-step cracks in block foundations usually indicate settlement. Vertical shrinkage cracks in poured concrete are common and often manageable. We assess all of these during your free inspection and tell you honestly what needs immediate repair versus monitoring.

Foundation repair in the Buffalo area ranges from $500 to $700 for a polyurethane crack injection on a simple crack, to $10,000 to $25,000 or more for helical pier underpinning on a settling foundation. The cost depends entirely on what type of repair is needed, how extensive it is, and whether the problem is structural or cosmetic. We assess and quote in writing before any work starts.

Structural foundation repairs generally require a building permit through the City of Buffalo or Erie/Niagara County Building Department. We handle the permit process as part of your project. Simple crack injections without structural modification typically do not require a permit.

The main causes in Western NY are: freeze-thaw cycling forcing water into micro-cracks and expanding them, frost heave from soil freezing to 48 inches below grade, clay soil shrinkage and swelling putting lateral pressure on walls, and age-related concrete carbonation. Buffalo homes built before 1970 often have poured concrete foundations with minimal steel reinforcement that are particularly vulnerable.

Simple crack injection with a DIY epoxy kit is possible for small shrinkage cracks, but professional assessment first is strongly recommended. Structural cracks, settling, bowing walls, and water intrusion all require professional repair with engineered solutions. Improper DIY repairs can mask symptoms while the underlying problem worsens.

A single crack injection is usually a same-day job. Helical pier underpinning depends on how many piers the settlement requires, typically 1 to 3 days for a residential foundation. Carbon fiber wall reinforcement for a bowing wall is usually completed in a day per wall section. We give you a specific timeline in your written repair plan.

We provide written documentation of the repair performed and stand behind our workmanship. Warranty terms differ by repair type (crack injection vs. structural underpinning) — we cover the specifics with you before work starts so there are no surprises.

It depends on the cause. Damage from a sudden covered event (like a burst pipe) may be covered; gradual settlement, frost heave, or normal wear typically is not. We are not insurance adjusters, so we recommend calling your carrier directly, but we can provide the documentation and photos most insurers ask for.
