"Troy and Chris (the owners) were amazing to work with... Extremely knowledgeable, pleasant to work with and very attentive... kept us up to date on status of project. Windows actually came in sooner than quoted and installed. Excellent job on installation. Project took 2 days to replace 11 old windows, frame, seal/caulk... stunning efficient new top quality windows. All old windows and materials were hauled away. The installer and helper were extremely efficient and very pleasant. They also kindly took some old storm windows etc. Joanne in the office was also very friendly, helpful and it was a pleasure to talk to her. All in all, we had a great and very satisfying experience working with everyone in this company. Everything was as they promised. HIGHLY recommend!!"
