Foundation Repair / Waterproofing in Hudson, Massachusetts

Mass Save will not pay to fix a foundation or install a waterproofing system, and Hudson has an eligibility wrinkle. The town is served by the Hudson Light & Power Department, which makes it a municipal light plant town, so homeowners are NOT eligible for Mass Save. For weatherization help, you go through the Hudson Light & Power Department's own energy programs, not Mass Save. Either way, neither covers foundation repair or waterproofing, those programs cover heating, cooling, and weatherization only. The adjacent overlap is basement air-sealing and crawl-space insulation, which the municipal utility's programs may support for Hudson homeowners. Treat any contractor claiming a state energy rebate on a French drain as misinformed, and check with Hudson Light & Power directly. Radon mitigation often piggybacks on sump work but is billed separately.

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 Hudson building department. Significant work like pier underpinning or wall rebuilds requires PE-stamped drawings from a registered Professional Engineer. Because the Assabet River and its wetlands run through town, exterior excavation, regrading, or drainage near them frequently falls under the Hudson Conservation Commission's jurisdiction through the Wetlands Protection Act, so a dig-out on a low or riverside lot usually needs a filing first.

Hudson sits in the MetroWest belt, where costs run below Boston metro but above central and western MA. A full interior perimeter French drain with a sump pump usually lands at $8,000 to $20,000 depending on linear feet. Single crack injection on block or poured walls runs $400 to $900 per crack. A standalone sump pump install runs $1,200 to $3,000, more with a battery backup that helps during Assabet flood events. Stabilizing a bowing block wall with carbon fiber or steel runs roughly $5,000 to $12,000, and settlement repair with helical or push piers runs about $1,500 to $3,000 per pier.

Hudson is a Middlesex County town on the Assabet River, an old shoe-and-mill town turned tech suburb, with about 19,947 residents across 8,560 housing units and a median construction age near 54 years. The stock mixes late-1800s and early-1900s homes near downtown and the former mills on block and stone with postwar and newer poured-concrete subdivisions spreading toward the Marlborough and Stow lines.

The Assabet River runs through the center of town, and low neighborhoods along it sit on saturated, clay-heavy valley soil with a high water table. Glacial till and clay lenses elsewhere hold water against basement walls. That combination drives interior French drains, sump systems, and crack repair on block and poured walls, with stone-wall sealing on the oldest downtown homes.
