Dennis Grynkiewicz Construction

Thirteen permits, and nearly every one is the same job: pull the old windows out and put new ones in, or wrap the house in vinyl siding. Dennis Grynkiewicz Construction carries a Mashpee address, but the permitted work sits nowhere near the Cape — Roslindale, Brookline, Arlington, Dorchester, Belmont, Weston, Everett, Melrose. Those permits run 2015 through 2022, so what exists here is a Greater Boston window-and-siding history that ended a few years ago. No one who hired them has written anything down that BuildZoom holds, which is why no rating is offered either way. The licence entry is the thing to sort out before calling. BuildZoom lists construction supervisor number CS-107667 twice — once as active when it checked in July 2026, and once as inactive, with a note that the Department of Public Safety at one point showed it cancelled. Both cannot be current, and neither was confirmed against the state's own records here. If windows or siding is the job, that is the work with a paper trail behind it. Check CS-107667 directly with the Department of Public Safety, ask what has been built since 2022, and settle whether they still travel up from Mashpee for Boston-area work before anything gets scheduled.
