Derek was a thoughtful and very personable sales representative. Scott with installation was detail oriented, thorough and also real friendly. WMGB was easy to work with and did a great job replacing our basement windows. The additional light from the egress window and the glass block windows was amazing. We are very happy with the results.

The four stars was achieved primarily because the installer knew what he was doing and handled the situation professionally.

We discovered this company while visiting relatives in Ohio. Since our initial contact to replace two sets of French Doors, the entire process has been exceptional, simple, and the products are of the highest quality (while not the priciest in the market!) No hesitation to recommend this company to anyone.

WMGB did a great job overall. The final result is a beautiful faux block window that gives the house a very elevated look. There was a little hiccup at first, but it was resolved by Emily in the most professional way. The installer, Thomas, also did a fantastic job with the installation. In the end, it turned out exactly how I imagined it would look.

2 big thumbs-up for WMGB, and especially our install crew of Thomas and Dan. Both guys were top-notch. Friendly, professional, worked with a sense of urgency - but not rushed. They replaced 6 basement windows with glass block and the results are fantastic. Would definitely recommend WMGB.

Everything went smooth, but the whole process took forever. We put the deposit down in November and it took until the end of March before the windows were installed. It felt like an extremely long time for 2 windows.
