Just had two new windows installed. Competitive price but best part was attention to detail and cleanliness during installation. These guys are efficient and competent and the new windows look great! Well done. You’ve earned a repeat and loyal customer!

We are completely satisfied with the installation, quality of the product (front door) and follow up service. We had a minor flaw in the glass and the service department promptly addressed the issue and replaced the glass insert. QSI gets top marks for standing by their products.

We are very impressed with QSI. The installer’s are very professional, and they got the job done quickly, but were very efficient. In every way we would rate QSI excellent!

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. Thanks guys.

Phenominal. The workers worked very well together. One did one thing, while the other did something else. They cleaned up everything both inside and out. The cost is a little bit higher, but it is money well spent. I would use them again in a minute.

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.
