Qsi Windows, Doors & Sunrooms reviews (103)

HAD ALL THE WINDOWS AND DOORS REPLACED IN OUR HOME. VERY HAPPY WITH THE SERVICE AND OVERALL QUALITY OF THE WORK. FEW PROBLEMS VERY RESPONSIVE, QUICKLY RESOLVED. DAMAGED GLASS AT POINT OF DELIVERY WAS REPLACED.MANY COMPLIMENTS ON THE WORKMANSHIP FROM OTHER CONTRACTORS AND VISITORS WHO HAVE BEEN TO OUR HOME.

The windows are wonderful, quiet,and much warmer.The men did great work, everything placed in to a tee.The windows were framed with nice solid wood,not plastic or skimpy looking wood,nicely mitered and cleaned up after the job was finished. They took all the garbage away and left nothing behind.This job was done over a year ago and we are still very happy. Thank guys.

Company installed new windows going back to outside and put in all new windows. They provided a wider sill in the kitchen and all work was completed in a timely fashion with absolutely no mess.

Recently had new kitchen, bathroom & two bedroom windows installed. Sales rep made excellent recommendations. Installation was scheduled for six weeks out due to the holiday season. Imagine our very pleasant surprise to get the call that not only were our windows in early but that everything would be completed in advance of Christmas. When the team came to install, I was very pleased to see that they had laid drop cloths, etc. throughout the house.

The quality of windows is excellent and their installers are in house employees with benefits. They did an excellent job and are worth the extra $. Great clean up and polite installers. I highly recommend this company.

we are very satisfied with our windows. They are easy to clean and open. My hus and saad today that the room was very warm. We like to save money on heat.

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.
