I've been in my remodeled kitchen for a couple months now, so it's time for my honest review. Long story short we had a small kitchen fire that became an absolute nightmare for my family and I. Our house is from 1957, so we needed to remodel anyway but not like that! Insurance paid for our hotels, our kitchen was gutted, and we had multiple contractors over promise and under deliver. By the 4th month, we were miserable! We found Ray on Facebook and I couldn't believe how easy he made everything!!! Ray always responded to my text/calls, came to every appointment on time, gave us no nonsense answers, and was reasonably priced. We just wanted someone to come in, get it done, and do it right. By some miracle, thats exactly what happened with Ray and his team! The day they finished I was literally crying because I honestly thought we wouldn't be in our house by Thanksgiving (let alone be able to host it!). So because of Ray and his team, he saved our Halloween, Thanksgiving, AND Christmas!! Thanks Ray, for coming to do your job, doing it well, and without issues. I truly appreciate you guys so much. And get ready because we're saving for you guys to come and do the rest of the house!
