    "We met with several builders about an addition we wanted to add to our home. Once we met Sean we were confident he was the right person. Sean has met all of our expectations and kept in contact with us through the entire process. If you are looking for a stress free construction project then Conniff Construction is the builder you should chose."

    "Conniff Construction is by far one of the best contractors in ocean county!!! It's very rare to see the owner on site guiding his workings but that's exactly what Sean did. The worksite was always clean , he was always in contact and open to mid-project changes. The project complete date was even pulled in to accommodate my children starting school. Highly Recommended! Excellent work !"


    Joe B.

    "My husband are I are considering a large home renovation, We contacted Conniff Construction and Sean was unbelievably helpful in helping us to making one of our biggest decisions yet! We had a thorough phone conversation discussing all of our expectations and booked time to visit the property, take measurements and plan out our project. We have spoken to a few contractors and feel undoubtedly confident in Conniff to deliver us an outstanding finished product! Cannot recommend Sean and Conniff enough!"
