"We are extremely satisfied with the work that Square Oaks Home Improvements did on our home. From the initial phone call to the follow up to the actual work, the quality of service was top notch. We desperately needed new windows, but put it off, due to all the unknowns. Would we be treated right? Would it cost too much? Would we get quality windows? Rick and company helped answer all our questions and dispelled our reservations. From Day 1 to the final installation, we felt we were treated with the utmost courtesy and respect. We would highly recommend this company for your window and door needs!"

"Jody was up front and extremely easy to work with! We love our new windows as they replaced the original ones from 1961. Nate did our install and he rocked it! Thank you both for a fantastic experience from start to finish. If you need new windows from a professional company, give Jody a call."

"My windows were so inefficient I couldn’t get the temperature above 63° in the winter. I used to put plastic on the windows and the wind would blow the plastic. Lol. Also there was a significant sound improvement living near Highway 441. Installation was bing bang boom and finished within a couple hours. (Installed 5 Slider WINDOWS Fall 2018)"

"Looks great, fast friendly service. Will use again on future windows"

"The installers were great. The salesperson made promises that he did not keep and he missed a window. When the person came to measure he also didn’t catch that I was having all my windows done except one. The windows look great. The response when I notified the co that one window was missed was very fast but added to my cost."
