Rated 5 out of 5

I've now been doing business with Costelow Glass and Door for over 3 years. I had them replace the windows on my house a couple years ago and had them come back recently for another window we wanted replaced. I can't say enough about the professionalism and craftsmanship that these guys had on the install and also using quality products with a 20 year warranty! I wouldn't waste time with anyone else. It's hard to find great trustworthy contractors these days!I've now been doing business with Costelow Glass and Door for over 3 years.

Paul is God sent and will always be my contact anything door/window related. He came over to fix immediately from the first call and is not only knowledgeable but a stellar human being. Stop your search and just call him! 🙏

Last week Paul and his son replaced two windows in my home and I couldn't be happier. He made the process so comfortable. His work was top quality as was his product. I must also make mention his attention to detail. I will definitely call on him for any future window projects

Costelow Glass did a great job replacing some old casement window hardware so we asked him for an estimate to replace our aging front door. He offered great assistance in picking the perfect door to go with our home and then did a beautiful, very professional installation. We highly recommend Costelow Glass and door!
