Edgar Li has completed work on my house for over 20 years. I trust him completely. He has always given me a excellent job and a very fair price. My wife and I always recommend Edgar and his company to our neighbors, friends and family.”

Like many of you, you employ some contractors that are decent but you have a select few contractors that you would recommend to anyone without hesitation. Crystal Exteriors is one of the latter for me. You get to deal with the owner, Edgar, directly. He communicates very well and is responsive. It was no problem for Edgar to give me an estimate on short notice, and the project was completed exactly as promised without a hitch. If you want a smooth job with personal attention and no drama, go with Crystal Exteriors.
