"John and Jason arrived on time and replaced a very large picture window and a smaller window. I am very happy with the windows . They look beautiful. John and Jason were very professional and did a wonderful job. Now I am kicking myself for not replacing a few more windows!"

"The salesman was very professional and covered all details with me. On the day of the scheduled install they arrived promptly but were unaware they were second floor windows and a third floor repair so he had to cancel. They were able to reschedule another crew the next day and they arrived promptly as well and got right to work. Each member of the team had a responsibility and they worked together perfectly. One of the window openings was not square so the installer had to work longer on that window to make sure it fil just right and slid open without binding. When they completed they did a great job cleaning up."

"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!"

"I own an 90-year old historic colonial high school turned into a bed & breakfast. The windows were neglected over the past 20-30 years and in serious demand of work. Modern day window contractors were not going to understand this job. It's very difficult to find a contractor that will come through on a promise and has the skill to do as they boast. The day that Grady stepped into my 90 year-old home that needed historic window restoration, he became a part of the house. He knew exactly what had to be done. More importantly, he understood my expectations. These windows needed special attention. There was a level of detail required that not any expert would be able to handle. Grady took the time to learn their needs and stayed on the job until it was to my satisfaction. He even reworked an entire window just because I didn't like the way that it looked. Grady truly showed expertise with his ability to work on such a delicate job and even taught me a few things about historic window repair. He replaced broken antique glass with one just as aged and just as historic. If a window had to be completely rebuilt beyond his solid estimate, he did it without any complications to my budget. My windows are not only restored, but they are literally brought back from the past. Any enthusiast will appreciate the lint-seed oil, putty, and antique glass that was all restored to perfection. It was a pleasure having Grady work with us. He even stayed in the house at times to make sure he was available for the job. In fact, we're going to rename the room in which he stayed to "Grady's Den". Thank for bringing character and craftsmanship to my investment!"

"A new doorknob and lockset was ordered and was supposed to be included with the installation but after the door was installed it was discovered that no doorknob was with the new door. The installer had to go buy the doorknob and return to complete the installation which may have caused him to rush the job because the storm door was not replaced properly . I had to wait about almost a week for the installer to return and fix the problem. I then discovered that the entrance door was also sticking but I did not report this to the company because at this point I was just disgusted not only with the installation but also with the flimsy quality of the steel door which is a thin gauge of steel, very lightweight and very easily dented. This was one of Angie's Super deals that I had paid in advance for without ever checking the quality of the door first. I will never pay up front for any service again.

I have had the same company install all mu home's replacement windows about 7 years ago and I was so completely satisfied that I guess my expectations were too high for the same result with a replacement door.
