When planning an outdoor project, it’s important to make sure the lumber you choose can withstand the elements.
That’s why your San Marcos McCoy’s carries YellaWood® pressure treated lumber treated with environmentally preferred Micronized Copper Azole (MCA) preservative. MCA protects the lumber from rot, fungal decay and termite attacks.
McCoy’s stocks doors in several common styles and standard sizes, allowing you to get in, get out and get building.
Doors special ordered through McCoy’s Millwork division are made to order which means we can personalize both interior and exterior doors to meet the needs of your project, whether it’s a single door or an entire house package.
Looking for something more unique? Pella® windows are beautiful, energy-efficient windows which truly reflect the style of your home and are available through Special Order.
Located just off of Interstate 35, McCoy’s Building Supply is proud to be a part of the San Marcos Community. Manager Randy Haas has been part of the McCoy’s team for over 30 years. He and his staff are dedicated to providing the best customer service for professional contractors, do-it-yourselfers and everyone else in between.
