Massachusetts licenses no foundation contractor, but residential work requires a HIC-registered contractor, and structural repair needs a Construction Supervisor License and a building permit from the Lunenburg Building Department. Significant structural work, such as underpinning or rebuilding a wall, requires PE-stamped drawings. Because Lunenburg has several lakes and brooks feeding the Nashua River system, exterior excavation, drainage, or regrading near those waters can fall under Conservation Commission jurisdiction through the Wetlands Protection Act, so confirm wetland setbacks before any near-water or hillside dig.

North-central-Massachusetts rates run below Boston metro. On Lunenburg's mix of poured and older masonry walls, crack injection runs $400–$900 per crack. An interior perimeter French drain with a sump pump for a wet basement usually lands around $8,000–$20,000 depending on footage, and a sump pump install is $1,200–$3,000, more with a battery backup that's worth it on a lakeside lot. Stabilizing a bowing or cracked wall with carbon-fiber straps or steel beams typically runs $5,000–$12,000, with rebuilds of failing masonry higher.

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.
