From the beginning of a project until the end, MCS Building Supply has the materials contractors, builders and homeowners need. Our products include roofing, insulation, drywall, siding, flashing, rebar, lumber, doors and windows. With a location in Hattiesburg, Mississippi, our materials are available via pickup or a free delivery.

NO JOB TOO BIG. NO JOB TOO SMALL!

Construction is just one of the things we do well

We want your building process to go as smoothly as possible. Our range of building materials includes roofing, insulation, drywall, siding, flashing, lumber, rebar, doors and windows. While materials in our full-line building supply yard are available for pick up, we are happy to arrange a hassle-free delivery — allowing you to focus on your projects, not logistics. Looking for a particular item? We can also arrange a custom order to ensure you receive what you want when you want it.
