They're excellent! I'd recommend Premier One Improvements, Inc all day long! My neighbor is going to use them and I think my dad is also going to use them. David's a good guy. His son is also doing a lot of the jobs now and he does good work. I met them at the Orange County Home and Garden show at the OC Fairgrounds and he immediately impressed me as very professional. He wasn't full of $@!#% like some of the other salespeople in the industry. I hired David to replace all of my exterior doors. Then I hired them to do all the interior doors as well. I've had nothing but good results from Premier One Improvements, Inc. His wife is instrumental in the business. She makes David hop and that makes him look good! The word that comes to mind when I think of David and Premier One Improvements, Inc is professional.
