I had heard about United Builders from several of our friends, they were all very happy with their new windows and doors. When we were finally ready to do our home, I knew I had to call Rick. Couldn’t be happier with how my home looks now. I recommend him to everyone!

I received 3 bids for my windows to be replaced. I decided on United Builders Windows & Doors because I believe the estimate was fair and honest. I had also gained additional knowledge of what exactly I would be getting without feeling pressured for any upgrades. The communication with the staff was excellent. They were always prompt and respectful. Upon install I was extremely impressed with the work and care to my home. The installers were trustworthy, helpful and took pride in their work. Overall I would highly recommend United Builders, they are true professionals!

Rick’s team did an amazing job. We had the whole house done (10 windows and 1 slider) I was a little nervous at first but after a few hours I couldn’t stop smiling with joy. I will definitely refer United builders windows and doors to all my Friends and family.

Rick was helpful and informative through the whole process! He had answers for every question we had. His build team was great! They worked efficiently and cleaned up and answered all of our questions as well. The whole thing ran smoothly and we are beyond thrilled with our new Anlin windows, garden box, and sliding door. Right away we've noticed that the house is quieter and the temperature change is far less drastic....no more drafts! Would highly recommend Rick and the United Builders team.

My husband and I did research and sought recommendations before settling on United Builders Windows & Doors to replace all 24 windows and 2 sliding doors in our home. Rick, the owner, came out to give us a quote. We were so impressed with his professionalism and his expertise in helping us choose the best windows for our project. In a timely manner, he sent out his assistant to do the final measurements. When our windows were finished, his crew came out and completed the installation in 2 days. They were courteous and clearly were experts at their job. Our windows are beautiful, work well and we couldn’t be happier with them.
