Interior Renovation
Repeat CustomerWe worked with Mike and CarrThom Development on a couple of projects… most recently a renovation. The whole project came out really great, and working with Mike and his team was a pleasure. They not only listened, but also helped develop our ideas into a more realistic form and really were great with the execution. Great attention to detail, and I think it all came out great. Throughout the process it was easy to work with them — they were accountable, honest, and we'd highly recommend them to anyone interested.

Design Consultations & Fireplace Renovation
CarrThom did a wonderful job of transforming my outdated fireplace and mantle from the 60's to a contemporary design. It perfectly complemented the home's updated aesthetic and increased its overall appeal. It was truly beautiful and I was very pleased.
