We had multiple quotes done, and Three Sons was by far and away most competitive. They were communicative and flexible in scheduling, arrived on time, did all the work in one day, cleaned up after themselves, and left everything looking pretty much like they’d never been there. The installers were friendly and professional. We’re extremely pleased with the quality of the windows, and of the work. We have a few more windows to replace in the future, and Three Sons will be getting the call when we’re ready to pull the trigger on the work.
