    The entire experience was truly great............and I have a wonderful window now to show off. Everything was done above my expectations -- a rare occurrence in today's world. Thank you for being customer oriented as well as providing a high quality product and workmanship.

    Love the windows. Significant noise reduction and house much warmer and electric bill much lower-all a plus!

    We had had two patio door units installed in 2014. We were so happy with the results, that we added 14 picture windows this year, along with a patio door unit in another room and a custom "half-round" window in a third. We do not have any more windows to replace, but if we did, we would contact RbA first.

    The installation crew were both professional and clean. We are extremely pleased with the double hung windows and sliding patio door. Looking forward to replacing more windows....

    We love the windows and patio doors. You can definitely see the quality, and we are proud to show everyone our Andersen windows and sliding doors. The screens are awesome (can't tell there are screens!) and the windows work with ease. We are ready to do the next phase!!
