    With 11 windows and one door to replace, I made sure that I did lots of research and received quotes from 7 companies. Douglas was one of the lowest prices. I eventually decided on them because the salesperson (Brandon) was the most responsive of the companies to quote. I am very pleased with the results. Sean and the installation team did a great job and I could tell the card about the end result. The guy who did the flashing on the outside (don’t recall his name) insisted on redoing a piece because it didn’t meet his exacting standards (even though it looked fine to me). I recommended them to my neighbour who is also getting a few windows replaced. I have my basement windows to do eventually and for sure will be calling Douglas.

    I have been more than satisfied with Douglas Window and Door Inc., and their professional installation of my windows. The workers were polite and helpful, cleaned up afterwards and did an excellent job. I would strongly recommend this company for all doors and windows.

    We had our patio door replaced by Douglas Window and Door a year ago and was very satisfied with the service and door quality. This year it was time to replace all our windows and we knew exactly where to go. We dealt with Christina for sales, Sean for measurements and Greg and crew for installation. Our experience with all was great. We added 3 new windows to replace 1 in our back room and therefore had to have the siding also replaced. Our house is older and to keep that feel inside we asked that sills be added to certain windows. Workmanship was excellent. The result is beautiful. Thank you!
