JCL Construction Inc.

Massachusetts has no foundation-contractor license, but the contractor must carry Home Improvement Contractor (HIC) registration, and structural work requires a Construction Supervisor License (CSL) plus a building permit from the Lynn Inspectional Services Department. Significant structural repair, piers, wall rebuild, or underpinning, needs drawings stamped by a registered Professional Engineer. With Lynn Harbor, the Saugus River, and tidal marsh nearby, exterior excavation, regrading, or drainage in the low neighborhoods routinely triggers Conservation Commission review under the Wetlands Protection Act, so confirm jurisdiction before any dig-out.

Lynn foundation pricing sits below Boston but reflects North Shore labor and coastal access. Crack injection typically runs $400-$900 per crack. An interior perimeter French drain with a sump pump lands around $8,000-$18,000 depending on linear feet, with low waterfront basements toward the upper end. A sump pump install is usually $1,200-$3,000, more with battery backup. Stabilizing a bowing brick or stone wall with carbon-fiber or steel runs $5,000-$12,000. Settlement repair with helical or push piers runs roughly $1,500-$3,000 per pier, with full projects often $10,000-$30,000.

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.
