Although I like the windows (which considering the price should be of the best of quality) I am very unsatisfied with the installation process, the warranty process and general foll0w-up service. Everything was delayed, the subcontractor was not who was listed as the installer (the head installer was on vacation), the installer signed that the job was complete when 3 windows had yet to be installed. The customer, NOT INSTALLER, was to supposed to sign to confirm completion of job. They did not follow the Pella installation protocol so windows were drafty and the warranty would have been nullified. I had them reinstalled. The thresh hold on my $12,000 door came off after 3 openings and I still haven't received replacement part (plus it is $150 minimum for any labor charge). Trouble getting through on phone (chalk up to COVID) but never got return e-mail. I would recommend looking elsewhere for windows.
