3 Sons Customs

3 Sons Customs is a Kingston, Massachusetts glass company. Its own website says it does both commercial and residential glass work — storefronts, curtain walls and glass railings for commercial clients, and windows, glass showers, mirrors, screen replacement, window cleaning and custom glass table tops for homeowners. Better Business Bureau rates the company A+, though its BBB category lists it as a fence contractor, which does not match the glass and window work described on the company's own site or its Procore listing for windows. The one third-party account found is a 2022 Google review describing a shower door installation that repeatedly sagged, with the reviewer saying a promised warranty repair went unresolved for four months and warning other homeowners to stay away. Anyone considering shower door or glass installation work should ask directly about warranty turnaround before booking.
