Garrett Callahan does business as GC Carpentry, a Cape Cod outfit based in East Falmouth offering cabinets, framing, finish carpentry, and deck building and repair. BuildZoom lists an active Massachusetts home improvement contractor license (#187758), issued in September 2025 and checked active as of March 2026. The permit record on file is limited: two of the three permits are at Callahan's own East Falmouth address — a $3,000 reroof in 2024 and a $1,200 wood-stove flue liner in 2022 — and the third is a 2024 electrical permit at a Marblehead property. For carpentry, cabinet or deck work on Cape Cod, ask for references and a written estimate before signing, given the license was only issued in September 2025.
