"Rick did removed cabinets for us in the kitchen and put in new lighting. He also did a lot of work finishing our basement. He put up a ceiling, a wall, built us a custom wet bar and finished all the basement trim. His quality of work is excellent, he is so easy to work with and is very flexible. His prices are great too. We will be calling Rick again for all of our future projects!"
