Extreme Pro Construction Services

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 permit from the Billerica building department, and significant structural repair needs PE-stamped engineering drawings. Billerica's wrinkle is wetlands. With the Concord and Shawsheen rivers and extensive wetland areas, a large number of lots fall within Conservation Commission jurisdiction, so exterior excavation, a French-drain outfall, or regrading near a wetland, brook, or river commonly triggers a Wetlands Protection Act filing. Interior drainage that stays within the basement footprint usually avoids that.

Billerica sits in outer Boston metro, where costs run moderate to somewhat high. Crack injection on poured walls runs $400 to $900 per crack. An interior perimeter French drain with a sump pump typically runs $8,000 to $20,000 depending on linear feet. A sump pump install alone runs $1,200 to $3,000, more with a battery backup that earns its keep on wet riverside lots. Stabilizing a bowing block wall with carbon-fiber straps or steel beams runs roughly $5,000 to $12,000, and settlement repair with helical or push piers runs about $1,500 to $3,000 per pier, with whole projects often $10,000 and up.

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.
