JMM Construction Corp.

JMM Construction Corp. is a family-run general contractor working the South Shore and Cape Cod, with Stephanie managing clients and projects and Chris leading crews on kitchens, bathrooms, basements, additions, and custom decks. The company says it was founded in 2023, after the birth of the couple's son Jackson — though the business's BuildZoom history runs earlier, with building permits and a review on file dating back to 2021. That BuildZoom profile puts the company's score in the top 3% of Massachusetts contractors, backed by $2,000,000 in liability coverage and $1,000,000 in workers' comp. Permits on file cover bathrooms, basement finishing, a load-bearing wall removal, and a wrap-around porch in Norwell, Harwich Port, Hanover, and Plymouth between 2021 and 2025. In a 2021 BuildZoom review, a Sagamore Beach customer described a clean, well-finished exterior paint job and called the company dependable and easy to work with. Its Massachusetts Home Improvement Contractor license (#208494) is active on the state registry, matching the current number BuildZoom lists for the business as an S Corp; BuildZoom also lists two earlier HIC numbers for the company as cancelled, and a Construction Supervisor license we haven't independently verified. Worth asking directly how the 2021 project history connects to the company's stated 2023 founding, and for more recent references given how much of the record predates that date.
