A-1 Windows & Doors LLC

Replacement windows and new doors are the jobs people hire A-1 Windows & Doors LLC for. Its Connecticut home improvement contractor registration, HIC.0550804, is active on the state registry, and the company says it has been in business 37 years and lists Simsbury and Avon in its service area. On Google it holds 4.7 stars from 44 ratings. One customer took a fair quote on "5-bedroom windows and a Bay-window" and said the bay window install was tricky, but Dan and his guys figured it out and blended the surrounding trim to match the rest of the house. That customer also said Sharon in the office supplied the paperwork and instructions for claiming the tax rebates. A building owner said A-1 has done repairs on their buildings in Simsbury for years; the latest job was a new fiberglass entry door for a warehouse, where Daniel suggested two squares of glass on top. A homeowner said they replaced all of the windows in the house, and a customer who used A-1 for both window replacement and a storm door replacement said both went well. In a 2025 review, a customer described garage repairs: the owner, Daniel, came at the scheduled time and noticed the framing around the old door was not sufficient to support the load-bearing wall, then offered priced options to widen the door to a 36-in opening. That 2025 customer said the rotted base plate and missing jack studs were installed and the new door is composite. A 2025 customer said Marcin and his team found weather damage under a bow window and fixed hidden repairs left by previous owners. In a 2022 review, a couple said their first job with A-1 was a large glass door with side lights that took quite a bit of carpentry. The office drew a complaint in 2025: a customer gave one star and said Sharon at the front desk was repeatedly condescending on the phone, so they went elsewhere, though they said the people who came out knew what was needed. In a 2023 one-star review, a caller complained of excuses and no returned phone calls.
