Martin Supply: What to Know Before You Shop for Building Materials in South Carolina

Martin Supply carries lumber, hardware, and tools across South Carolina with locations in the Lowcountry and Midlands

Martin Supply is a regional retailer with multiple locations throughout South Carolina, primarily serving contractors, builders, and homeowners who need lumber, fasteners, hand tools, power tools, and general hardware. The company operates as an independent business rather than a national chain, which means inventory and pricing can vary between locations. If you are planning a renovation, repair, or construction project, knowing what Martin Supply stocks and how their locations are organized will help you plan your shopping trip and budget accordingly.

The company has been part of South Carolina's building supply landscape for decades, with a reputation for stocking both common materials and harder-to-find items. Their staff typically includes people familiar with local building codes and regional construction practices, which can be useful if you have questions about what materials work best for Lowcountry humidity or Midlands weather conditions.

Finding the Martin Supply location nearest you

Martin Supply operates stores in different regions of South Carolina, with concentrations in the Lowcountry (around Charleston and surrounding counties) and the Midlands (around Columbia). The easiest way to find your nearest location is to call their main number or check their website for a store locator. Having the address and phone number before you go saves time, especially if you are looking for a specific item and want to confirm stock.

Each location has its own hours, which may differ from other stores in the chain. Some locations close earlier on Saturdays or may have different weekday hours depending on local demand. Calling ahead also lets you ask whether they have a particular size, grade, or brand in stock before you make the drive.

What Martin Supply typically stocks

Martin Supply carries the core materials most building projects require: dimensional lumber (2x4s, 2x6s, and other common sizes), plywood, oriented strand board (OSB), fasteners (nails, screws, bolts), and hardware (hinges, handles, brackets). They stock both pressure-treated lumber for outdoor projects and standard lumber for interior framing. Pricing on lumber fluctuates with market conditions, so the cost of a 2x4 or sheet of plywood today may differ from last month.

Beyond lumber, Martin Supply carries hand tools (hammers, saws, levels, tape measures), power tools from common brands, and general hardware like electrical boxes, conduit, and plumbing fittings. Paint and stain are usually available, though the color selection may be smaller than at a national big-box store. If you need something specialized or in a quantity they do not regularly stock, staff can often order it for you, though delivery time varies.

Pricing and payment options

Martin Supply's prices are generally competitive with national chains for standard items, though regional independent retailers sometimes offer better pricing on bulk orders or specialty materials. Because Martin Supply is not a national chain, they may negotiate on price for larger projects—it is worth asking if you are buying materials for a significant renovation or new construction.

Most Martin Supply locations accept cash and major credit cards. Some stores offer contractor accounts or volume discounts for regular customers, so if you are planning multiple projects, ask whether you may have access to. Return policies are typically posted at the register or available by phone; most stores accept returns of unused, unopened merchandise within a set timeframe with a receipt.

When to call ahead versus walking in

For small, common items (a box of nails, a single 2x4, a hammer), walking in works fine. For anything larger—multiple sheets of plywood, a specific grade of lumber, specialty fasteners, or power tools—calling ahead saves frustration. Staff can tell you whether the item is in stock, what sizes are available, and sometimes hold items for you if you are coming later that day.

If you are working from a contractor's list or a detailed project plan, bring that list with you or read it over the phone. Martin Supply staff can often suggest alternatives if an exact item is out of stock, or they can order what you need if the timeline allows.

Delivery options and large purchases

For large orders—truckloads of lumber, bulk fasteners, or materials for a major construction project—ask about delivery. Not all locations offer delivery, and fees vary. Some contractors arrange their own delivery or rent a truck, which may be cheaper than the store's delivery fee depending on distance and order size. Confirm delivery costs and timing before you commit to an order.

If you are buying enough material to fill a truck bed or trailer, Martin Supply staff can help you load, and they can often advise on how to secure and transport materials safely. For very large orders, getting a quote in writing (including delivery cost, if applicable) protects you from surprises at checkout.

Building supply alternatives in South Carolina

South Carolina also has national chains like Lowe's and Home Depot, as well as other regional suppliers. National chains typically have larger selections and more consistent pricing across locations, but they may have less local knowledge. Specialty suppliers focus on specific materials—roofing suppliers, electrical distributors, plumbing wholesalers—and often have deeper inventory in their category.

For a small repair, a national chain may be more convenient; for a large project or specialized materials, comparing Martin Supply with other regional suppliers can reveal better pricing or selection. Understanding what each type of supplier does well helps you choose the right place for your particular project and budget.

Frequently Asked Questions

Does Martin Supply deliver to my home?

Some Martin Supply locations offer delivery, but not all. Call your nearest store to ask about delivery availability, minimum order amounts, and fees. For small orders, you may find it cheaper to pick up yourself or rent a truck.

Can I return lumber if it warps or splits after I buy it?

Return policies vary by location, but most stores accept returns of unused, unopened merchandise with a receipt within a set timeframe. Lumber that has been cut, stained, or installed is typically not returnable. Ask about the return window and what condition items must be in when you purchase.

Does Martin Supply stock pressure-treated lumber?

Yes, most Martin Supply locations carry pressure-treated lumber for outdoor decks, fences, and other projects exposed to weather. Availability of specific sizes and grades may vary by location, so call ahead if you need a particular dimension or treatment type.

What should I bring when I visit Martin Supply?

Bring your project plan or a detailed list of materials, your measurements, and any samples (paint chips, hardware styles) that show what you are looking for. If you have a contractor's estimate or specification sheet, bring that too—it helps staff find exact matches or suggest alternatives.

Do I need a contractor license to shop at Martin Supply?

No. Martin Supply serves both professional contractors and homeowners. You do not need a license to purchase materials. Some locations offer contractor accounts with volume discounts, but these are optional.
