KGS staff was great! Professional, friendly and did quality work. I will definitely go to them first from now on!

They are absolutely the best window company around. Professional workers that put in a true 8 hour day. Quality, and I mean quality work.... perfectionest at their jobs.....They are truly a five star business...

Replaced all windows on 2nd story as well as couple 60+ yr old windows on 1st floor. Most were double hung - but biggest transformation was an old old slider than was caulked shut with storm window - to glass block with vent. So very happy with how everything turned out! Will be using them again for future projects!

Staff is very knowledgeable and helpful along with being friendly. I highly recommend doing business with KGS ask for Andy.

I was really impressed how quickly and efficiently they repaired our porch screen. I know they were backed up on orders, but they were here within a week to do our repairs. All the employees were extremely friendly too!

I have used KGS many times and am always very pleased with their work. Very friendly installers, they take the time to protect the floor, and clean up when finished. I recommend them highly.

I am very pleased with their work. They replaced 4 rotted basement windows and a cellar access door that had been glued shut by a previous owner. Quick response when I requested an estimate. Cost was very reasonable. Results just as promised. Cleaned up after job was finished.

The windows were exactly as ordered. The installers were professional, quick and very tidy. I highly recommend!

Dave met with me twice to review all the options before ordering 12 windows.They did the install 1 1/2 days and their quality work and clean-up was awesome. I highly recommend them, job well done!

Really great people there!!

KGS did our entire home. Excellent service from start to finish!
