I hired Pete Sullivan more than three years ago to help replace a small section of siding on my suburban house in New Jersey. Since then, he has not only replaced all the siding and roofing on my house, but completely renovated the entire interior, a multiyear job that included moving many walls, installing new tiles for the entire first floor, completely renovating the kitchen, and building a new gas fireplace and a custom cabinet for a TV lift. He most recently finished renovating a second-floor bathroom. Pete is a pleasure to work with, and all of his work, and the work of his team, is top quality. His design suggestions are always insightful. Our next project is to install updated heated and cooling systems, as well as a solar collector.- Jason F.

As a professional engineer having 33 years of experience in the NYC construction industry, I can be at times over critical when having work performed at home. Issues like scheduling work, attention to detail, and trying to get fair value for the work performed can be troublesome. Well, NOT with P J Sullivan. I was given an initial estimate and schedule and they meet both as promised. Their (and especially Peter and brother Dan Sullivan’s) attention to detail exceeded my expectations! They really do strive for perfection. Having our home renovated by Peter and Co. was effortless. I can’t say enough about how pleased my wife and I are with the work performed by PJS.- John C.
