What materials and products Capital Supply carries

The store stocks framing lumber in common sizes and grades, plywood for sheathing and subflooring, and oriented strand board (OSB). Drywall comes in standard thicknesses, and roofing materials include shingles, underlayment, and flashing. You can find fasteners—nails, screws, bolts, and anchors—organized by type and size.

Hand tools include hammers, saws, levels, tape measures, and chisels. Power tools range from basic drills and circular saws to larger equipment depending on current inventory. Paint and stain selection covers interior and exterior finishes in multiple brands and colors. The store also carries caulk, weatherstripping, hinges, locks, and other hardware items that finish a project.

When to buy from Capital Supply versus other retailers

Capital Supply works well when you need to see and touch materials before buying—lumber grade, plywood thickness, and paint color all matter more in person than in a photo. If you need materials cut to length or have questions about which product suits your specific project, staff can help you decide on the spot. This saves a trip back to the store if you buy the wrong thing.

Contractors often choose Capital Supply because they can build an account, order in bulk, and have materials ready for pickup or delivery. If you are a homeowner buying a few items for a weekend project, the store's local location means no shipping wait and no restocking fees if you need to return something. If you know exactly what you need and want the lowest price, online retailers may undercut the store, but you lose the ability to inspect quality and get same-day pickup.

How to prepare before visiting

Bring measurements and a sketch of your project if you have one. Know the dimensions of the space you are working with, the type of finish you want, and any specific requirements—for example, whether you need pressure-treated lumber for outdoor use or fire-rated drywall for certain rooms. If you are matching an existing material, bring a sample or a photo.

If you are buying lumber, understand the difference between nominal size (what it is called) and actual size (what it measures). A "2x4" is actually 1.5 inches by 3.5 inches. Knowing this prevents buying the wrong dimensions. If you are unsure, write down your measurements and ask staff to help you pick the right product before you buy.

Delivery and bulk order options

Capital Supply can arrange delivery for large orders, which matters if you are buying enough materials to fill a truck. Delivery costs vary based on distance and order size. For contractors and builders who order regularly, the store can set up an account that tracks purchases and may offer volume pricing.

If you need materials delivered to a job site, call ahead to discuss timing and any site access requirements. Same-day delivery is sometimes possible for local orders, but this depends on current workload and order size. Asking about delivery options before you finalize your purchase helps you plan your project timeline.

Returns and exchanges

Most building materials can be returned or exchanged if they are unused and in original condition. Lumber and other materials that show wear or damage cannot be returned. If you buy the wrong size or type, bring your receipt and the unused item back to the store. Some items may have restocking fees depending on the store's policy.

Paint and stain are typically final sales once opened or mixed to a custom color. If you buy paint and realize it is the wrong shade, you can exchange it for a different color, but the store will not refund the original purchase. Asking about the return policy before you buy expensive or hard-to-use items protects you if your project plan changes.

Tips for getting the most from your visit

Go early in the day if possible, especially on weekends, to avoid long lines and have better access to staff for questions. Bring a list of everything you need so you do not forget items and have to make a second trip. If you are new to a type of project, tell the staff what you are building—they often have suggestions about materials that work better than the cheapest option.

Ask about sales and promotions on items you need. Building supply stores often run specials on seasonal materials—roofing in spring, heating supplies in fall. If you are planning a project, timing your purchase around these sales can lower your total cost. For large projects, ask whether the store offers contractor pricing or volume discounts even if you are not a regular contractor.

Frequently Asked Questions

Does Capital Supply cut lumber to size?

Many building supply stores offer cutting services for lumber and plywood. Call ahead or ask staff when you arrive to confirm whether this service is available and whether there is a charge. Having materials cut to length at the store saves you time and ensures accuracy, especially if you do not have a saw at home.

Can I order materials online and pick them up at the store?

Some building supply retailers offer online ordering with in-store pickup, but this varies by location and company. Contact Capital Supply directly to learn whether they have an online ordering system and how long pickup takes after you place an order.

What should I do if I buy the wrong material?

Bring the unused item and your receipt back to the store as soon as possible. Most materials can be exchanged for the correct product. Paint and stain mixed to a custom color are usually final sales, so double-check the color code before you leave the store.

Do I need a contractor account to shop at Capital Supply?

No, the store serves walk-in customers and homeowners. You can purchase individual items without an account. If you plan to order regularly or in large quantities, ask staff about setting up a contractor account, which may offer volume pricing and account tracking.

What is the difference between pressure-treated and untreated lumber?

Pressure-treated lumber is chemically treated to resist rot and insects, making it suitable for outdoor use and ground contact. Untreated lumber is less expensive but will decay outdoors over time. Use pressure-treated for decks, fences, and outdoor structures; use untreated for interior framing and projects that stay dry.
