"Loved working with Custom Exteriors. Very responsive to inquiries. Precise in their measurements, estimate and timeframe for completion. Highly recommend them."

"Custom Exteriors provided a great product and good service in replacing 2 sliding glass doors and 2 other windows in my townhouse.  One was a custom window that required extra work in refitting the plantation shutters to the new window.  Although there were some bumps along the way, Jeff and his foreman Ryan excelled at follow up.  I would recommend Custom Exteriors."

"Kevin one of the owners of Custom Exteriors contacted me the following day and immediately tried to make things right. The first thing, I was impressed about was he took my call without hesitation. Many medium sized business will bounce me around to different people before finally being able to talk to the owner. He was an attentive listener and took to the time understand my needs and wants in an exterior entry door.His communication was top notch, sending me estimates the same day or the following day. He gave me choices in fiberglass doors: ProVia and Therma-Tru, hardware: Trilennium vs Emtek, and single point vs multiple point locks. I just ordered a ProVia doors through Kevin. This surprised both to my husband and me. Before contacting Custom Exteriors, we thought we were going to get a Therma-Tru door, but that totally changed once we the information we needed from Kevin. I get the sense that he truly wants to give customers options and information, but respects the customer's final decision. There is not high pressure sale pitch. Kevin wants customers to be informed and happy with the end product."
