Evans Home Improvement — registered as Frank Evans Company, Inc. — is a Cohasset outfit that builds sunrooms, three- and four-season rooms and porch enclosures, and fits replacement windows, patio doors, siding, decking, awnings and roofs across the South Shore. Massachusetts registry records show an active Home Improvement Contractor registration, #100892, held by Frank Evans Company Inc at its Cohasset address, and the company publishes that same number on its own site. The Better Business Bureau has it accredited since 1962 with an A+ rating, and lists it as a Five-Star CertainTeed Contractor and a Harvey Elite Dealer. What homeowners describe most is the room work. A 2025 customer converting a screen porch to a four-season room wrote that two workmen were courteous and left the site clean and tidy every day; another that year said their three-season room was designed exactly as envisioned and finished on time. A 2018 reviewer gave the fullest account: a gable-design sunroom with double-pane low-E windows, insulated floor and ceiling and a roof shingled to match the house, quoted among the lowest of six contractors, with the crew arriving on time daily and cleaning up each evening, plus a kitchen slider replaced with double French doors. The owners turn up themselves. A 2026 reviewer had Rich come out to assess a patio door and pick a style; a 2019 customer was contacted by Larry Evans the next business day, and Larry came to the house personally to assess the deck and bid the screen room. Several people describe coming back over decades — one for 30 years of windows, storm windows and patio doors — and reviewers repeatedly note installers who have been with the company for many years. There is one thing worth raising directly. In a March 2019 review a homeowner wrote that on the second day of the job they came home to find the installers inside the house without prior knowledge or permission, and that the crew's explanation was that a window was open. Two milder notes: a 2018 customer said the project took a bit longer than originally anticipated, and a 2017 customer recorded that the company returned to repair a leak in a door it had installed, with the owner replying publicly to apologise and send a service rep the next morning. A sensible call if you want a sunroom, porch enclosure or window and siding work from a licensed, long-established South Shore firm whose owners run the estimate themselves. Agree access arrangements in writing before day one, and confirm the schedule and the specific product line — one 2020 reviewer wished they had chosen a wood builder rather than prefabricated metal panels, and said so was their own preference rather than a fault of the company.
“Great work, returns calls, shows up on time and a pleasure to work with. Fair and honest family business that I’ve used many times.”
great experience over the years
Very happy with this company. They were responsive, quick ,and helpful in every way. Also happy with the product.
We had Rich come out to take a look at our patio door that needed to be replaced. We discussed what we wanted and he actually knew what the replacement should be. He helped us with a style that would best fit in the space and home. His crew were exceptional. So polite and professional. Would hire the Evans Home Improvement Group in a heartbeat. PS.. My Mom hired Rich's Dad 50-60 years ago. I always remember how my Mom and Dad would over the years praise the exceptional job he did. He replaced their windows and siding that I can recall. I did not know who to call for our patio door, in the back of my mind I thought of the Evan's Company. I googled the Evan Home Improvement Company and to my surprise they were still in business. BEST DISCUSSION EVER!!!
Over the last 30 years I've returned over and over to Evans Home Improvement for windows, storm windows, patio doors. They've been super reliable, done top quality work, and offered excellent advice to meet my budget and needs.
Straightforward estimate and logistics. Polite, friendly, considerate crew. Great attention to detail. Our three season room has added so much pleasure and value to our house.!
