Bass Restoration & Waterproofing, Inc.

Massachusetts has no foundation-contractor license, so confirm Home Improvement Contractor (HIC) registration. Structural repair, piers, steel beams, or wall rebuilds, requires a licensed Construction Supervisor and a building permit from the Hanover building department, with PE-stamped engineer drawings for significant work. The North River is a state-designated Scenic River with strict protections, so exterior excavation, drainage, or regrading near it or the surrounding wetlands routinely falls under Hanover Conservation Commission jurisdiction through the Wetlands Protection Act and can face tighter review than elsewhere.

South Shore pricing runs below Boston metro but above western Massachusetts. Crack injection with epoxy or polyurethane on a poured wall, common on Hanover's newer stock, typically runs $400–$900 per crack. An interior perimeter French drain with a sump pump generally lands around $8,000–$20,000 depending on linear feet, often near the high end on lots draining toward the North River. A sump pump install runs $1,200–$3,000, more with battery backup. Crawl-space encapsulation runs $5,000–$15,000.

Massachusetts requires a written contract and a Home Improvement Contractor registration for most residential foundation repair & waterproofing work; ask for the registration number and check it before paying a deposit.
