Sentry Glass Co

Drop a broken storm window at Sentry's Lawrence counter early enough in the morning and it is usually ready the same day. One 2022 customer paid $25 for a repair other shops wanted more than $100 for; another brought in eight broken windows and had them all back that afternoon. Sentry Glass has been in Lawrence a long time — its BBB listing records 42 years in business, and a customer wrote in March 2026 that her family has used the shop for more than 30 years, and that the current owner, Damien, worked there for decades before taking it over. Its Google page holds 4.7★ across 67 ratings; Porch, which lists the company for glass, screens, storm windows and shutters across eastern Massachusetts, has it at 4.4★ from 39. Speed runs through most of what customers write. A business with a shattered window in 2021 was kept updated by the office and had the glass replaced within two hours. A health-care facility with a broken window got the same treatment in 2023. A 2024 customer had two house windows done in a single day, and the shop stayed open ten minutes past closing so she could collect them. In July 2025, a customer watched Luke and Taylor set glass in his yard in about ten minutes. It isn't only counter work. A 2025 customer had windows replaced across an old craftsman house and booked the second floor for the following year. A 2024 commercial customer used the company for the windows on a mixed-use building in Methuen. Custom-made windows come up more than once, priced the way the rest of the shop prices. Customers also keep naming the office — the secretary, the front desk — which for a drop-off-and-collect business is most of the experience. Spanish-speaking customers single out the staff and the pricing in the same breath. One thing to check before scheduling: the company's Massachusetts home improvement contractor registration is expired on the state registry. For a pane carried into the shop that may not matter to you; for whole-window replacement on your house, ask where it stands, and about insurance, before the work goes in the book. For a broken pane, a storm window, a screen, or a set of replacement windows in the Merrimack Valley, this is the fast, inexpensive, long-established option. Call early in the day if you want it back the same day — one 2022 customer found things slower when the shop was busy.
