"This review is a bit overdue. Had new doors and windows installed in early 2021. I had a very good experience with this company and with Mr. Edward Dunn. He was very prompt in answering all my questions and also patient as he worked with me while I tried to decide among the various options for doors and windows. I felt he offered me very fair and reasonable prices compared to some other quotes I received. Am especially grateful for him even considering my business since my order was quite small, and I have been finding that, esp. during COVID times, many companies won't consider the 'smaller jobs.' There were a few problems during installation (one wrong window size, flaw in a door screen), but Mr. Dunn promptly addressed these and everything was resolved to my satisfaction. I absolutely love my new windows and doors. Oh and the installers were fantastic. Really nice guys. Did outstanding, beautiful work and didn't leave a mess. I am all around very, very happy I chose this company."

"From start to finish it was a great experience. Fred came out and spoke with my husband and myself. He was very sensitive to our needs and budget. I loved the door that we chose. Installation was amazing the crew arrived on time and treated our home as if were theirs. I would definitely use this company again."

"What a great experience. Ronnie helped us with the measurements and came back to install. Delivery was 2 weeks early (which is unheard of during COVID) and the installation was terrific. Shutters look fabulous and we couldn’t be more pleased. Quality is great, pricing competitive and service without flaw. The perfect combination."

"Great experience from start to finish. William was a fantastic sales person. He was not pushy. He took the time to explain and was very good with following up and keeping me in the loop. Also, did not request a 3-4 hour presentation on the windows like some of the big companies. A+ Robbie was very professional and efficient when it came to measuring for the new windows. Took time to explain the process and answer my questions. A+ Ronnie's crew who handled the install were professional and efficient. Very impressed with the job they did to complete the work in one business day. Again, A+ If you need windows, look no further than Apex (call William Powars)."
