Gsc & Carpentry Corp

What exists for this Malden company is a registration and a permit file — BuildZoom has not collected a single customer review for them. Gsc & Carpentry Corp works out of 18 Loomis St in Malden and is owned by Gilson Cardoso. BuildZoom lists an active Massachusetts home improvement contractor registration, #206984, which it says it checked in March 2026 — that is the directory's own claim rather than confirmation, so ask to see the registration and a certificate of insurance yourself. One oddity is worth raising directly with them: the 10 permits BuildZoom attributes to the company are all residential low-voltage audio/video and data wiring jobs in Brookline and Chestnut Hill, pulled between 2006 and 2010. That is neither carpentry nor recent, and it is a fair question to put to the owner. Treat this as an unproven listing rather than a bad one. Ask for references and addresses of finished work before handing over anything larger than a small job.
