Foundation Repair / Waterproofing in Hanover, Massachusetts

Mass Save does not cover foundation repair or waterproofing, the program funds heating, cooling, water heating, and weatherization, not French drains, piers, or crack injection. Disregard any rebate pitch tied to drainage work. The real overlap is the energy side of the basement: crawl-space encapsulation and basement air-sealing and insulation can qualify for Mass Save weatherization incentives, with air-sealing often subsidized at 75% or more up to program caps.

Hanover is served by National Grid, an investor-owned utility, so homeowners here are Mass Save eligible. A free Home Energy Assessment opens the door to those weatherization rebates. Radon mitigation often shares trenching with sump and basement work but is not itself a Mass Save measure.

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 Hanover building department, with PE-stamped engineer drawings for significant work. The North River is a state-designated Scenic River with strict protections, so exterior excavation, drainage, or regrading near it or the surrounding wetlands routinely falls under Hanover Conservation Commission jurisdiction through the Wetlands Protection Act and can face tighter review than elsewhere.

South Shore pricing runs below Boston metro but above western Massachusetts. Crack injection with epoxy or polyurethane on a poured wall, common on Hanover'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 draining toward the North River. A sump pump install runs $1,200–$3,000, more with battery backup. Crawl-space encapsulation runs $5,000–$15,000.

Hanover is a Plymouth County town on the South Shore with 14,773 residents and about 4,973 housing units, at a median construction age near 55 years. Most of the stock is later-20th-century colonials and ranches on poured-concrete foundations in subdivisions off Route 53 and Route 139, with older homes near the Four Corners and the historic North River area.

Hanover borders the North River and its broad protected wetlands, and much of town drains toward those low areas. Combined with a high water table, that drives basement seepage, hydrostatic pressure, and damp crawl spaces, while winter freeze-thaw adds cracking to poured walls.
