Owner
Bill has been our go-to contractor for over 10 years. He has remodeled a covered deck into a room, remodeled a kitchen and finished it after we had to relocate to another state and is currently assisting us in our on-going efforts to update what had been a very neglected house.
Bill is reliable, dependable and his permitted work has been complimented by our town inspectors as well as suppliers.
He works independently primarily, calling in help only when a job requires it. For some who have a tight time frame, this might be a drawback. We appreciate the high standards, finished work and integrity Bill has always provided us in each of the jobs we've hired him to do.
