Crew was on time and very professional. We had five windows installed— three in a bay window in our drawing room and two upstairs in our bedroom. Quality of the windows is outstanding. Installation was tricky as the windows were installed in a Victorian terrace house where nothing is square. Installers did a great job fitting the windows. Work was to have taken two days but completed all in the same day. By 4:30 pm, all debris was cleared. You would have never guessed crew was there. Our security company came the next day to reinstall the sensors and commented on the quality of the job. The same for our painter who was painting the outside of our house and saw installation first hand. Would certainly recommend to friends and family.
