DSR Custom Design Build is a carpentry outfit run out of 41 Bowdoin St in Winthrop, with Richard Tyrell Jr listed as the owner. The work it advertises is the finish end of the trade — cabinets and trim rather than framing or whole-house builds. That is nearly everything there is to say, because no customer has written about the company anywhere we could find. BuildZoom gives it a score of 94, which the site says puts it in the top quarter of Massachusetts licensed contractors, but that number is BuildZoom's own arithmetic on licence and permit records, not a verdict from anyone who hired them. On licensing, the picture is worth a question or two. BuildZoom lists a Massachusetts home improvement contractor registration, #181507, and says it checked the licence in March 2026 — we did not confirm that against the state registry, so treat it as the directory's claim. The same profile also attaches two Florida records to the company: a construction registration it labels unverified, last checked with a December 2025 expiration, and a certified general contractor licence, #CGC1513401, shown inactive after being cancelled. Directory licence records regularly attach to a similarly named business in another state, so ask which of these are actually theirs. Worth a call for cabinet and trim work in Winthrop and the neighboring towns. Ask for the current HIC registration number, verify it yourself on the state's consumer affairs site, and ask for two or three recent local references — there is no published customer history to lean on.
