I called around 8:30 on Monday morning in an absolute panic. I have a large dog that busted out an awkward sized window in my living room. It’s summer, it’s hot and my doggy needed his window fast! I sent them a picture of the window and the approximate size and they had me all fixed by around noon. Needless to say I’m very happy and would highly recommend them to anyone! Thank y’all much!!!

Instiglass did a great job repairing a 22 year old broken window. They responded fast anytime I had a question. Dustin was the installer, he was very nice & professional. Would definitely recommend!

I had 3 windows replaced where the seal had broken. The Inst-I-Glass of Knoxville was very prompt with service, offered a 10 year warranty, and perfectly matched to my current windows. Both the person who gave me my estimate and the installer were very professional promptly did their jobs. I have had the windows in for a few weeks and I am very satisfied.

Awesome people, and great service. They were able to fit me into a busy schedule with last minute notice on an emergency.

We had to have a very large, tempered window replaced above our bathtub in our master. Brian and Teri were very efficient and professional. Their team was very clean and worked quickly. From start to finish we had zero communication issues and they provided us with everything we needed for the window.

Excellent service! The guys went above and beyond given the weather we were having. Highly reommend!

Replaced a broken 2nd floor window. Professional, prompt, courteous, thorough!

Dont use, total rip off they were waste your money, and not even called you back or they may just keep your money and not replace the glass, lazy owner not worth using find another company I urge you
