Tim O?Sullivan and his crew are the best

Joe L.

For window, door, and siding installs, Tim O?Sullivan and his crew are the best. I won?t go too deep into details, but they installed my insulated siding, new windows (including a bow window), and door. Everything came out great and they did the work in the winter snow. From the start to the finish the crew was on top of it and Tim (the owner) was either on site or communicated every day. They took care of all the little extras and did the minor changes without charging extra or writing up a change order. I can?t praise them enough for their professionalism or excellence.

I would recommend O?Sullivan Installs in a heartbeat

We had a large project to do. We wanted to re-side our whole house, including all the trim. I got 5 bids for the job, and O?Sullivan was in the middle. I chose O?Sullivan due to their excellent reviews on Angie?s List & the fact that we were very comfortable with George, the gentleman who provided the bid, explained all our options, etc. He was upfront about everything, very persistent in getting back to us when we had questions. There were no unknowns when the job began. After meeting Tim, we knew we had made the right choice. Tim & his crew did a super job, in a timely manner. The job was done from around Thanksgiving to just before Xmas. We did not have the best weather, yet the crew worked diligently to get finished before Xmas, working Saturdays & Sundays as well. They ran into various issues & always communicated with us exactly what was going on. Guess the thing that impressed me most was the job cost what they said it would cost, even though we ran into some wood rot issues, that could have cost us thousands more to repair. They ate that cost, providing an excellent solution. Can?t say enough about the great job they did. We constantly get compliments from the neighbors on the great job they did. They kept the site as clean as possible, always tidying up before going home. I would recommend O?Sullivan Installs in a heartbeat. Tim is a super guy as are all his team members.
