TESTIMONIALS

Carlene A. of Potomac, Montgomery County, MD 20854

(Found on CheckBook.org) I cannot say enough positive about Edgar Li, the owner of Crystal Exteriors. I have over many years as a homeowner contracted for many services, and I can say with absolute certainty that Crystal Exteriors is the best -- the BEST -- service provider I have ever used. I had an issue with plantation shutters that were on my old French doors and wanted to use them on my new patio doors. No other door company, large or small, could assure me that my shutters would work. Edgar guaranteed it. His product is beautiful, his prices are more than fair, and he was completely knowledgeable about his product. He called when he said he would and he showed up when he agreed to be here, Installation day was perfect. Edgar and his workers arrived right at the agreed upon time, they were fast and efficient and cleaned up after themselves. All in all, I recommend Edgar and Crystal Exteriors without hesitation or reservation.
