Jeff did a fantastic job for us converting a window into French doors and creating an outside covered deck. The work was completed on time and at the agreed price. Everything was very tidy and a great quality of workmanship. Jeff was able to bring up many points to be considered based on his experience which ensured that we had the desired outcome. I would not hesitate in recommending this company, and we intend to arrange for further work at a future date.
