"Darryl and his nephew did great work again, even as we added more to the remodel he made time to do the work. He replaced some of the sub flooring where I had weak spots, all new flooring and baseboard with accent. He also ripped out my old sliding glass door and replaced it with French doors that I bought which he also picked up for me. He will be doing my guest bathroom shower next."

"Amanda was really very good! At first I was very skeptical, thinking why did I pay money to just speak with someone on the phone about my kitchen remodel project... but after just a few minutes of her addressing some of the issues/questions I emailed to her earlier, I knew it was worth it. It was very clear that she knew her business and she gave me several ideas that I had not even thought about. I told her that I would definitely recommend her to friends and I will very likely use her again myself for my next home project!
