    We just had A1 install a bay window. Their quote was fair so we decided to go with them. Their crew spent the day installing the window. I was at home so I was able to watch them work. Their attention to detail, work ethic, and the quality of the work they did was outstanding. The clean-up afterwards was very thorough both inside and out. I would highly recommend this company for any replacement windows work. Awesome!

    I've used A1 Unique Installations a couple of times, and I've used some of their competitors.

    They're not the cheapest, but I would say, you get what you pay for. Their craftsmanship, and attention to detail are second to none. You really see it in the little things. The way they are always cleaning and vacuuming, the detail in how they cap around a window or the fit of their trim. They just do that little bit extra, in my opinion.

    Very satisfied. Would highly recommend.
