Coughlin Construction

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 Kingston building department, with PE-stamped engineer drawings for significant work. Kingston's bay frontage and the Jones River make the Conservation Commission a frequent stop: exterior excavation, drainage, or regrading near the river, the shore, or coastal wetlands typically falls under the Wetlands Protection Act, so confirm jurisdiction before any dig.

South Shore coastal pricing runs below Boston metro but above western Massachusetts. Crack injection with epoxy or polyurethane on a poured wall, common on Kingston'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 near the river or bay. 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.
