Massachusetts has no foundation-contractor license, but the contractor must be Home Improvement Contractor (HIC) registered, structural work requires a Construction Supervisor License and a building permit from the Town of Barnstable building division, and significant structural repair needs PE-stamped drawings from a registered engineer. The Cape wrinkle is jurisdiction: a large share of Barnstable lots sit near coastal banks, marshes, and ponds, so exterior excavation, drainage, or regrading frequently falls under the Barnstable Conservation Commission through the Wetlands Protection Act, and waterfront digs may also touch the 100-foot buffer or floodplain rules. Plan filing time before any outside dig-out.

Cape Cod costs run higher than inland Massachusetts because crews travel and material delivery is longer. Crack injection typically runs $400 to $900 per crack. A crawl-space encapsulation, the most common Barnstable project given the housing stock, usually runs $5,000 to $15,000 depending on square footage and whether a dehumidifier is added. An interior perimeter French drain with a sump pump runs roughly $8,000 to $20,000, and a sump pump install alone $1,200 to $3,000 with backup. Exterior excavation and membrane waterproofing, harder on tight or wet coastal lots, can run $15,000 to $30,000 or more.

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.
