    About Us | Conniff Construction in Mantoloking, NJ

    Residential and Commercial Construction Company in Mantoloking, NJ

    The father and son team at Conniff Construction has over 50 years of experience in the construction industry. We specialize in delivering unique projects using high quality craftsmanship along with an unmatched level of customer service. John Conniff founded the company in 1976 and established a distinguished track record of unparalleled honesty, integrity, trust, and excellent craftsmanship. His son, Sean, learned these skills and values; nearly being raised in work boots and a tool belt, surrounded by his father’s core beliefs and unsurpassed work ethic. To expand on his knowledge, Sean continued working full time while earning a Bachelor’s Degree in Construction Management from Drexel University and becoming one of the youngest NARI Certified Remodeling Project Managers (CRPM) in the state of NJ. Today, Sean continues building the legacy of fine craftsmanship and superior service in construction after being awarded Best of Houzz for Service 7 years in a row and bringing in the 2018 NARI Contractor of The Year award.

    “Sean Conniff of Conniff Construction is amazing!!! From the time we had our 1st consultation, I knew we were in good hands with our kitchen renovation. Our kitchen in Spring Lake looks awesome- what a transformation!!! Sean is professional, innovative and well skilled. He was always on time and met our expectations in completing the project when promised. No small feat during COVID! He coordinated all the subcontracting seamlessly. We were not onsite during the renovation and Sean kept in frequent communication with us including texting us multiple photos of the progress. We are extremely happy with our new kitchen and will definitely be hiring Conniff Construction for our next project!”



    “Conniff Construction is the BEST! Sean and his team are professional, kind and hardworking. I will definitely use Conniff Construction again. As well as recommend to my family and friends. Thanks again Sean!”
