Tri-County Building Supplies was founded in 1964 and has been serving the needs of Southern New Jersey contractors for over 50 years. Tri-County was built on our first hand knowledge of the products we carry, pride in service, and personal contact with our customers.


The motto at Tri-County Building Supplies is

“Buy Where The Builders Buy”


While outlets and big box stores can offer some of the products we carry, we are set ahead of the pack by our experience and commitment to customer service and education. Many members of our team have experience working in the construction industry, and most of our employees have worked with us for decades. If you are not sure on the exact product you need, you can rest assured that someone on our floor is. Even if you are just looking for some general information while considering a job, pay us a visit and get some great ideas from the brightest minds in the business. We take pride in our community, and our success has allowed us to support and give back in many ways. We offer support to many schools, clubs, churches, and many more worthwhile causes. From material estimates and charge accounts, to load-sequenced deliveries – we’re with you every step of the way! Count on Tri-County Building Supply.


We carry all types of millwork, windows, doors, lumber, roofing, siding, drywall, and the list goes on. Give us a call to discuss your next project. Check our Locations tab to find a store near you.
