Dedicated to customers

M & M Building Supplies has been locally owned and operated since the doors were opened in August of 1986. The owner, Larry Mardell, is usually the first person you see when you walk in the door and is typically the one to answer the phones. It's not too often you see the owner of a buisness have as much communication with their customers as Larry does. Being an independent retailer in a big-box community sounds intimidating but it really has its advantages. We are not in the "rush" that big-box stores are in. We have the time to listen to you and your needs and we really want to get to know all of our customers.

M & M Building Supplies is a building supply dealer for contractors, new construction, renovators, do-it-yourselfers or hobbyists. Browse our catalogue, call us, or stop in and visit. The choice is yours. We are ready to help you with your dreams, your materials list and the details of your project.

Being a member of Castle Building Centers since 2001 means that we buy factory direct and our pricing is competitive with big box stores. Can't find what you're looking for?

Just ask us and we can get it for you!
