MILAMAKS CONSTRUCTION

Massachusetts has no foundation-contractor license, but the contractor must be Home Improvement Contractor (HIC) registered with the Office of Consumer Affairs, and any structural repair needs a Construction Supervisor License plus a building permit from the Wilmington building department. Significant work like pier underpinning or wall rebuilds requires PE-stamped drawings from a registered Professional Engineer. Given the Ipswich River headwaters and heavy wetlands, exterior excavation, regrading, or drainage near these resources frequently falls under the Wilmington Conservation Commission's jurisdiction through the Wetlands Protection Act, and in areas with known groundwater contamination, water-handling during a dig-out may face extra scrutiny, so file early.

Wilmington sits in the northern Boston suburbs, where costs run above central MA. A standalone sump pump install runs $1,200 to $3,000, more with a battery backup that earns its keep given the high water table. A full interior perimeter French drain with a sump usually lands at $8,000 to $20,000 depending on linear feet. Single crack injection on a poured wall runs $400 to $900 per crack. Crawl-space encapsulation runs roughly $5,000 to $15,000, and settlement repair with helical or push piers runs about $1,500 to $3,000 per pier.

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.
