Massachusetts has no foundation-contractor license, but the contractor must be Home Improvement Contractor (HIC) registered. Structural repair, piers, beams, or wall rebuilds, requires a Construction Supervisor License and a building permit from the Stoughton Building Department, with PE-stamped drawings for significant structural work. Exterior excavation, drainage, or regrading near the town's brooks and wetlands in the Neponset and Taunton watersheds can fall under the Conservation Commission's jurisdiction through the Wetlands Protection Act, so confirm before any dig-out near wet ground.

Stoughton costs sit in the South Shore-adjacent band, modestly below the Boston core. Crack injection typically runs $400–$900 per crack. An interior perimeter French drain with sump pump usually lands at roughly $8,000–$20,000 depending on linear feet, often the right call on this flat, wet ground. A sump pump install runs about $1,200–$3,000, more with battery backup. Stabilizing a bowing or cracked wall with carbon-fiber straps or steel beams typically runs $5,000–$12,000. Crawl-space encapsulation generally falls between $5,000 and $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.
