Sloan Windows exceeded all expectations! Communication was easy and effective. I was able to get an estimate immediately on a Saturday, which took about 10 mins. The quote was less than half of what Home Depot quoted. Work was done less than a week after the consultation, completed in half a day, the employees were professional and punctual, and the work is high quality. Anton informed me of a 2 year warrantee on the sliding door, low E tempered glass, and energy saving qualities. He was even willing to give me a discount if I purchased two. Will definitely be calling in the future for all glass and window needs!
