Treated Lumber

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.

Doors

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.

Windows

We carry a variety of Atrium® aluminum and vinyl windows in stock to meet your building and re-modeling needs. We can also custom order windows to match the look and size of windows already in place. 

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.

STIHL

Looking to take your yard care to the next level? Your San Marcos McCoy’s is proud to carry STIHL® outdoor power equipment.

We also have employees who are specially trained for service, assembly and part replacement of STIHL® equipment.

Farm & Ranch

McCoy’s is a one-stop shop for all your Farm and Ranch needs.

Secure your pastures with Stay-Tuff® fencing and manage your cattle operation with Priefert® calf tables, gates and other livestock equipment. We even have feed and pet supplies!
