"We are extremely happy with how our new windows and new front door turned out. After some unexpected challenges with the way our home was built, our installation crew quickly and efficiently adapted to make sure our windows and door were installed with expert care. Every time we see our new beautiful picture window we are left breathless! And our beautiful front door is the perfect upgrade for the look of our home. Thank you RBA!"

"Stefan Korn and his crew removed and replaced all of the rotted and ripped screen-panel walls and doors that made up our screened porch with his far superior screen/frame products -- dog-proof screen on the lower panels and regular screen on the top. He and his crew performed the work in an exceptionally professional and timely fashion and somehow managed to keep everything remarkably neat and tidy during the process. We couldn't be more pleased with the finished product. We also truly enjoyed working with Stefan and his men. They have our highest recommendation. Their work is worth every penny."
