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.

My wife and I are pleased to provide the following information relating to PJ Sullivan Construction. The company recently completed a substantial project at our home, in a thoroughly professional and efficient manner. The work progressed on schedule as outlined at the commencement of the project without interruption or delay. The quality of the work, as well as the conduct of the staff, was of the highest standards. The property was kept safe, clean, and secure throughout the project. We were made aware of any changes and/or offered suggestions, without any pressure to spend additional sums, and always adhered to our ultimate decision. We had been involved with construction projects on many previous occasions but this was our first time working with PJ Sullivan Construction. We were very pleasantly surprised in both, our dealings and the final results.- Adolfo L.
