Licensed and insured contracting company with promising work and beautiful results. No job is too big or too small.

"I have been using Done-Rite Contracting for more than 7 years now. They have doing various jobs for me from small ones like mounting a tv or ceiling fan to large ones such as a new gazebo install and a complete bath gut tub to shower renovation. The quality of their work and attention to detail is what sets them apart from other contractors. They include you in all aspects of the project insuring that you completely satisfied when they are finished. The Dans, as I call them, are very respectful of you and your home and take extreme care during the construction project to contain the mess and clean up daily. Many people are concerned at who they allow in their home, but these men are very trustworthy and professional and have such pleasant personalities that you will look forward to the next project and want them return."
