"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!

"Mr. Smith was able to remove the base of the light fixture. While he was doing this he found a loose wire that was live, so he reattached all my wires properly. He was then able to reattach my pull chain and put the light back up. I was relieved that he fixed the wiring problem to prevent future safety issues. Wonderful work and thoughtful demeanor."
