We Deliver

McCoy’s is proud to offer same or next day delivery.

Treated Lumber

McCoy’s carries high quality, pressure treated lumber that has been treated with an environmentally preferred MCA (Micronized Copper Azole) preservative. That means that if you’re building a deck or replacing a fence, you can find exactly the right treated lumber for your project to hold up to the elements.


Farm and Ranch

Whether you operate a small hobby farm or a large ranch, your local McCoy’s carries supplies for your operation’s needs including cattle panels, fencing, gates, pet supplies and much more. McCoy’s Building Supply is also proud to carry top-of-the-line Priefert® Ranch Equipment.


A fresh coat of paint is an affordable way to transform your home. Whether you’re searching for the perfect exterior paint color for your house or needing a high-gloss formula for your kitchen cabinets, McCoy’s and Glidden® can help. The paint department at your local McCoy’s can even color match samples you bring in. Plus, we have paint brushes, drop clothes, painter’s tape and other painting accessories in stock so you can purchase everything you need in one convenient trip.


If your home needs new windows, stop by and see the folks at your Duncan McCoy’s. Whether you need aluminum clad wood windows or double hung replacement windows, McCoy’s can help. Our in-store displays showcase the features of many windows and styles from brands like Pella®, Atrium® and Krestmark® so you can have a variety of window price points to choose from.  



Increase your homes curb appeal when you shop McCoy’s for interior or exterior doors. We carry a variety of exterior doors ranging from secure steel doors to stylish solid wood doors. Along with standard interior door styles, McCoy’s also stocks pantry, closet and pocket doors to maximize space in your home.


Both professional roofers and homeowners can find the roofing material they need at McCoy’s. Your Duncan store carries laminate architectural roofing shingles from Owens Corning® along with hip roof shingles that provide a more uniform ridgeline. Our roofing starter strips eliminate the need to cut regular 3-tab shingles, resulting in a faster and more cost-effective project.
