L & M Glass Corporation

L & M Glass Corporation has been cutting and fitting glass on Old Yarmouth Road in Hyannis since 1983. It calls itself a local, family-owned glass and mirror company, and the Better Business Bureau records it as a four-person corporation started in January 1983 with Avelino Lopes as owner and Daniel Lopes as vice president, graded A+. It keeps a showroom and does its own beveling and polishing in house, which is why the work that comes back in reviews tends to be custom rather than off-the-shelf. Mirrors and shower glass dominate. A customer writing in May 2024 ran three jobs through them at once — dry bar mirrors and shelves, a guest bathroom vanity mirror, and primary bathroom vanity mirrors with a shower glass door — and wrote that the staff gave real recommendations on the options and their trade-offs rather than just taking the order. When one of the mirrors turned out wrong, it was replaced promptly and without argument. They take on the awkward retrofits too. A customer in December 2021 had sliding shower doors fitted over a botched job from the 1980s; the company ordered a piece to make the old opening work, raised a safety concern about the old fitting for the resident, and finished it cleanly with, in the reviewer's words, no surprises or delays. A 2023 customer who had the side panel of a slider replaced wrote that they did what they said they would do for the price they quoted. The most recent account, from June 2026, is a set of triangular master bedroom windows measured and replaced — the customer singled out the fitter, Dan, for quiet, clean work and a tidy site, though they also noted the job took a bit of time. Further back, a 2022 reviewer sent by their BMW dealer described a specialised windshield replacement and praised the help in dealing with an insurer pushing them elsewhere. Across Google the company holds 4.6 stars from twenty-two ratings, and all eight written accounts on file, running from 2021 to 2026, are five stars. With a four-person shop the sensible questions are about timing rather than quality: ask when the glass will be ordered and cut, whether the piece is stock or custom, and what the lead time actually is before you commit.
