Owner
We did work with Bill Nappo and his team last year. He renovated a bathroom in our old house and took care of a few minor things along the way.
We found Bill to be completely responsible and timely. His workmen left virtually no footprint while in the house, and made sure to minimize the disruption. They were timely and careful. When after the job was completed we needed a little touch up to a few things, Bill took care of them without hesitation.
We are anticipating more work next year and we will call Bill. He is not inexpensive, but the work is top quality.
