Foundation Repair Contractor in Greater Boston

Foundation repair in Massachusetts ranges from $3,500 for epoxy injection of dormant hairline cracks to $15,000+ for horizontal crack stabilization with carbon fiber straps and drainage correction. Wall stabilization with helical piers for significant settlement can reach $20,000–$31,000. Schlickmann provides fixed-price proposals after on-site assessment.

Vertical cracks less than 1/8 inch wide that haven't changed in years are typically dormant settling cracks — low priority. Horizontal cracks, cracks wider than 1/4 inch, stair-step cracking in block walls, or any crack accompanied by wall bowing or water intrusion are serious and require immediate professional assessment. Schlickmann offers foundation assessments for Greater Boston homeowners.

Minor crack repair (epoxy injection) typically doesn't require a building permit. Structural repairs involving carbon fiber straps, helical piers, or underpinning do require permits in most Massachusetts municipalities. Schlickmann handles permit applications for all structural foundation work.

Yes — interior waterproofing using a perimeter drainage channel, sump pump, and vapor barrier is effective and far less expensive than exterior excavation and membrane application. We recommend interior waterproofing for most Greater Boston homes where exterior excavation would require removing landscaping, decks, or driveways. Exterior waterproofing is recommended when the exterior membrane is compromised.

The primary causes are: (1) Normal concrete shrinkage during curing — creates vertical hairline cracks that are cosmetic. (2) Freeze-thaw cycles — water infiltrates cracks, freezes, expands, and widens them over time. (3) Soil pressure from expansive clay soils saturated by poor drainage — the primary cause of horizontal cracks and wall bowing. (4) Settlement from inadequate bearing soil beneath footings — causes diagonal cracking and uneven floors. Schlickmann identifies the cause before recommending repairs.
