Treated Lumber

If you’re shopping for wooden fence posts or deck materials, your local McCoy’s Building Supply is the place to go. Not all treated lumber is created equal but at McCoy’s all 2x6 and greater dimensional treated pine lumber is treated for ground contact, which means it has almost twice the concentration of preservatives as above ground rated lumber. Our full-service lumberyard also has a drive-thru so our crew can load your decking boards or landscape timbers right into your truck helping you get back to building quicker.



What’s one of the quickest ways to refresh your home? By repainting a room! The paint center at McCoy’s can provide ideas for bedroom paint colors, kitchen paint colors or even just share tips on how to paint if you’re a first time DIYer. Plus, McCoy’s carries high quality Glidden® paints in a variety of interior and exterior formulas and sheens.


When repairing your roof, make sure you start the project by going to your local McCoy’s which carries all the roofing supplies you’ll need. McCoy’s carries Owens Corning® roofing shingles in a variety of colors to enhance the look and feel of your home’s exterior along with roofing felt, roofing vents and hip and ridge roof shingles to complete the job.


The right door provides a welcome entrance to your home and enhances curb appeal while also protecting your home’s most valuable possessions. Your local McCoy’s carries a variety of in-stock interiorand exterior doors, and an even wider range of doors are available through special order. McCoy’s also carries storm doors, screen doors and sliding barn doors along with all the hardware needed to correctly install each door type.



Moulding is the unsung hero of home design, quietly tying together ceilings, walls and floors. A house looks unfinished without the proper trim and moulding. McCoy’s carries crown moulding, shoe moulding, baseboard trim and more. Most moulding available at McCoy’s is primed and ready to be painted to match your home but we also carry solid wood moulding that can be stained and pre-finished moulding for times when you need the job to be done a bit quicker.   


Let in the natural light and transform your home with energy efficient aluminum and vinyl Atrium®windows, available at McCoy’s. With several common sizes and styles of windows in stock, and first-class Pella®windows available for Special Order, McCoy’s can help you find the best fit for your home or project.
