What Our Customers Say

We take pride in expertly fitting YOUR custom window into YOUR home.

Crew was fast efficient and clean. They wasted no time and where pleasant and helpful to explain how the units functioned and if I had questions they did their best to see I was supplied with answers.

Except for the lock on the screen door, I LOVE my new windows!! With the screen door locked, the screen still opens!! Why have such an inexpensive lock on a screen door that is part of such expensive windows???

Very please with the appearance and function of the five large windows installed. Easy to clean. Incredible sun and cold protection!

The new patio sliding door is both beautiful and functional. Your crew was able to install the door within the existing wood frame. The person you recommended for staining the wood was able to match the existing wood perfectly. Thank you!

We had some windows installed two years ago. We were very pleased with the windows. We decided to get three more windows completed this time. We are very pleased with the product and the installation.

We are incredibly impressed by the quality of our new windows, and all the employees that we worked with have been tremendous! Extremely satisfied! Thank you!

The whole project was exceptional. The windows are terrific and the crew that installed them were highly efficient and professional. We couldn't be happier.

My new patio door is very energy efficient and much stronger than the original unit installed when our house was built 15 years ago. The sales rep, the technician who measured the door opening and the installers were great people to work with.

Very pleased with the workmen that came to install the windows. They brought in tarps to keep my wood floors from being damaged. They also explained what they were doing and why it was being done. Thanks for the great experience.

Great job, wonderful product, excellent service. We will continue to upgrade the rest of our windows as our budget allows.

Completely amazed by the difference these Windows have made. Looking forward to completing the remaining windows in our project.

The initial intro was very helpful and informative. The 'measurer' was good. The installation crew were great. We had difficult oversized windows and they took their time and efficiently completed the job.

I knew I would have to paint , but anticipated the trim wood would have been sanded prior to installation . Nail holes weren't filled either .

These windows truly are beautiful. So much so that I will be getting new window treatments that don't cover them up so much like my previous wood blinds. I want to show them off.

The installation crew was very courteous, prompt, and professional. They worked with me on the design of the trim and accommodated minor design changes. We are extremely pleased with the outcome and have had many positive comments from visitors.

Your windows are great. You're installer were very professional and very pleasant to deal with.

It was a pleasure to watch two guys who were knowledgeable, pleasant, thorough and efficient - and worked well together!

Completed job in less than estimated time. Very professional work. Very friendly Answered questions freely.

We had to wait for one window to be installed because it was damaged, re-ordered, second one was damaged and re-ordered again.

Great product- worth the price because it will last. Installation process (and personnel) did a superb job.

The timeline ended up being later than we were initially quoted. We had to call and check in when the timeframe had passed in order to get a date on the books for the following month.

Installers were great. Pride in what they were doing reflected in thier great attention to detail. Could not be more happy with my experience with the product and installation.

RBA is a complete business. They are very careful while they work. They knew what was going on with all the workers and salesmen on the job.

All the people I worked with were so friendly, informative, and professional from the scheduler through the installers. My next door neighbor noticed the improvement and I gave her my booklets along with my recommendation. Thank you.

The reps, the communication, and the installation process were all first-rate. Love my new windows!
