What Our Clients Are Saying

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

Brian I.

"We needed to replace 5 windows in our house, and after receiving a couple quotes it was an obvious choice to go with Custom Exteriors. Robert was knowledgable and thorough in his initial visit, and was able to explain the entire process exactly as it played out. Thanks to Toni & Cesar for their follow ups and professionalism as well. Jose and the installation crew did an excellent job, worked very efficiently and left things looking great. The project couldn’t have been smoother from start to finish. Any issues, questions or concerns were promptly answered/cleared up by Robert, and the staff had great customer service attitude all around. Highly recommended for any job!"

Clyde L.

"Love my new double-paned windows.  I was so pleased with the work from this company a few years ago that I had them back.  The workmen arrived on time, did a beautiful job, and left everything in perfect condition.  The windows and door open so easily and the look is amazing.  I should have done this sooner! Thank you for this great job!"
