"Jim went thru our options for replacement doors and we got exactly what we wanted. The two gentlemen who installed the door was courteous and asked me questions about glass on top and bottom for storm door without assuming. I really appreciate that. Door is beautiful!"

"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!"

"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."

"The whole process went smoothly. Product was available within estimate dates. Scheduling occurred per our needs. The removal of exiting tub/shower and installation of new shower was completed in one day. Shower looks great. Everyone involved was extremely friendly. Installation team installed all accessories after consulting with us on locations. Great Job all around. We are now engaged with the company to replace our upper floor windows later this year."
