Edgar and Crystal Exteriors are truly exceptional. He brings to mind the quality craftsmanship of yesteryear, where expertly trained carpenters really care about the quality and appearance of their work. We had two exterior doors replaced, and the installation was both efficient and very surprisingly clean - one of the crew members spent considerable time just cleaning up, sweeping, removing old woodwork and hardware, etc. We couldn't be happier with the job, and heartily recommend Crystal Exteriors to anyone needing their services.
