TESTIMONIALS

Edward K. of Bethesda, Montgomery County, MD 20817

(Found on CheckBook.org) We had an excellent experience with Crystal Exteriors. Edgar Li, the president, was always available and checked on the work every day. His advice and suggestions were excellent. We were notified when each section of the job (siding, roofing, gutters, doors) would be started and completed. All the crews were very experienced, worked hard and tidied up when finished. There was not a moment's worry on our part. Edgar also did extras that were much appreciated (relocated backdoor light, added a porch outlet, changed the garage frame). He recommended and used the highest quality materials. The price was very reasonable, but the value was superior. Highly recommended. First, the best professional advice (from Edgar Li) that we have encountered. He is a graduate engineer, very smart, very experienced, very dependable, always reachable, very quality conscious, very responsible for the quality of the work performed. Could not ask for more. The workers have been with him for years and we watched them in admiration. The work was performed sooner than anticipated. The quality of materials chosen was tops. We were very glad to have "discovered" Crystal Exteriors. We were frustrated in finding an excellent contractor. We had had offers that ranged from one-half to twice as much as what we paid. Most importantly, we had zero confidence in the people that were making those offers. Edgar Li is top notch. We had not met anyone like him.
