# JB Sash and Door **Trade:** Windows / Siding / Gutters · **Address:** 280 2nd St, Chelsea, MA 02150, USA · **Phone:** (617) 884-8940 · **Website:** http://www.jbsash.com/ · **Languages:** English **Rating: 3.1/5** (medium confidence) — from 19 reviews across 5 sources. 74% of sentiment-scored reviews read net-positive. Last 6 months: 1 reviews, 1 negative. ## The honest read JB Sash and Door has been Chelsea's window-and-door shop since 1940 — it started as the "Home of the Window Boys" custom millwork operation and is still run by three family co-owners, Rick, Ron, and Sal Bertolami, working today as a Marvin windows and doors distributor across greater Boston. The reviews that carry the most detail are about the people on the job: Ed getting a warranty issue on a new door resolved without a fight, installation crews (David and Gleb; Jason and Jon) leaving job sites clean and keeping customers updated with photos during two-day installs, and sales staff like Andrew, Heidi, and Jackie Muse walking customers through the showroom and paperwork. Several repeat customers say they've come back more than once over the years for windows and then a front door. The complaints worth knowing about center on bigger-ticket orders. A 2024 review describes 8 Marvin windows costing $18k arriving with visible quality problems — glue smeared between panes, unsanded wood, missed paint — and a 2023 review says the company charged a customer to replace a sash that had been damaged sitting too long in JB Sash's own warehouse before pickup. A 2025 review, while praising the salesperson, says the company won't quote prices upfront the way a big-box store would. Separately, a 2026 review describes a measurement appointment that fell through and took six weeks of the customer's own follow-up to get rescheduled. JB Sash reads well for a standard window or door replacement handled by one of their regular installation teams. For a large multi-window Marvin order, it's worth asking about their inspection process before pickup and getting pricing in writing early. **Strengths:** - Installation crews — clean, communicative, and on time - Warranty support — resolved a door issue promptly - Family-run since 1940 — three generations still involved **Concerns:** - Pricing not disclosed upfront — ask for costs before signing - Marvin window quality — bulk order drew defect complaints in 2024 - Slow follow-up — one 2026 review cited a six-week wait for measurement ## Claims & citations Every claim below is backed by real evidence rows — uncited claims are dropped in code before publication. - Family-owned window and door company operating since 1940, currently run by co-owners Rick, Ron, and Sal Bertolami _(confidence: medium)_ - [Official Website](http://www.jbsash.com) — “Company history (self-reported): Since 1940, starting as the 'Home of the Window Boys' custom millwork shop.” - [Official Website](http://www.jbsash.com) — “Ownership (self-reported): Multi-generational family business; co-owners listed as Rick, Ron, and Sal Bertolami.” - Self-described as a leading Marvin windows and doors distributor for New England _(confidence: medium)_ - [Official Website](http://www.jbsash.com) — “Stated certification/affiliation: Leading distributor of Marvin windows and doors in New England” - A warranty issue on a door was resolved promptly by staff member Ed _(confidence: medium)_ - [Google Reviews](https://www.google.com/maps/reviews/data=!4m8!14m7!1m6!2m5!1sCi9DQUlRQUNvZENodHljRjlvT2w5Uk1uZ3lNRU5mU2kxb1lsQnFSekZQZW1sS1NWRRAB!2m1!1s0x0:0x10cda5ab0400fdca!3m1!1s2@1:CAIQACodChtycF9oOl9RMngyMENfSi1oYlBqRzFPemlKSVE%7C%7C?hl=en) — “5★ I have used JB Sash, working with Ed, for our renovation windows and doors.
