Our house is about 20+ years old, and I had changed the first 10 windows in 2017 during the first green home program, and I didnt want to change all at one time as not sure about the windows quality, and I was glad I did that way, the workmanship is horrible, basically the installers were a group of temporary workers that had no skills, the trim were pasted with some compound that even now we cant sand and print it properly, then the 2nd company for the two bedrooms and dining room windows change, the installation quality was good however the windows quality was bad, we had a leaking situation weeks after the installation. Learning from the previous experiences, I had very carefully choose the window company for the remaining windows this time, after gone through some quotes and recommendations, I picked Arctic vinyl Windows this time, Mike is very friendly and helpful whenever we had questions, changes and updates, and followed up for the issues I found during the installation. The windows quality so far looking good and workmanship also good, except one minor issue that our basement windows had a thick wall, and may caused some difficulties for the installation, and the metal trim was a bit damaged, but should be easy fix by our own, overall we are happy with the service and quality.
