We hired Peter to renovate our basement. Our basement looks fantastic and we spend so much time in it.- Patty D.

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.

We are very satisfied with all the planning and work done by PJ Sullivan Construction Company on our home. They exceeded our expectations and are very happy we went with them for our project. Peter, the owner, provided all of the construction and cost details, professional suggestions, and explanations that we needed to make informed decisions. The project management and workmanship were excellent! The guys who worked on our home were very skilled (and VERY nice!) and we really appreciated the constant presence of the Project Manager, Dan, from start to finish. We would definitely go back to PJ Sullivan for all our future home projects too.- Mike R.
