Qsi Windows, Doors & Sunrooms

have been using qsi for the last 5yrs. love the windows and the doors they have installed. still have a few more to do and will get them to install. you might pay more but the quality is second to none. would highly recommend them to anyone who is getting windows, etc

QSI windows and doors replaced 6 window and two doors in my house. They were very professional and the finished product looks fabulous. They were very clean and polite, working quickly to finish the job. I am very happy with the end result.

QSI replaced two large front windows and a back door for us. They were very meticulous about their work. They cleaned up after each job. There was a slight problem with the door (slight surface scratch) and they came back to repaint and left us touch up paint. We will use their services in the future.

QSi originally did all my windows and enlarged the dining room, which looks great. About two years later, I had them come back and enlarge one other windows when renovating the kitchen. The brick layer did an excellent job matching the existing brick work on the house. The windows look great and have helped in reducing my heating costs.

They did an exceptional job, with a good clean up, they were fast and efficient, and used quality products, they were very informative. Also, they were on time with their delivery, and had no hidden costs.

We needed windows replaced in our entire house and had QSI supply and install the windows. They were very informative during the consultation and measurement appointment. When the installers arrived, they were polite and professional. They took their time in completion of the details of installation, such as the appearance of the caulking and cleaning all of the windows when they were done. They also finished the inside of the new windows for us.

Set a time frame and was always prompt showing up.Answered all concerns pre and post installation.Worked around unexpected obstacles during installation.Followed up on added repairs need post installation .Tried to be as neat as you can with major work around finished work.Reasonably priced.Just be aware that entrance stoops change when new doors put in that affects
the smooth entry with wheelchairs or cane users.
