San Antonio summers don't mess around. By late May, we're already seeing triple digits, and that heat takes a real toll on your home's exterior. The good news? A little preparation now can prevent expensive repairs later. Here's what you should be checking as we head into the hot months.
Inspect Your Exterior Paint
Walk around your home and look for signs of paint failure - peeling, cracking, bubbling, or chalking (that white powder that comes off on your hand). These aren't just cosmetic issues. Damaged paint lets moisture into your siding and trim, and that moisture expands and contracts with our temperature swings, making the damage worse fast. Small touch-ups now can prevent a full repaint later.
Check Your Caulking
The caulk around your windows, doors, and trim is your first line of defense against water intrusion. Texas heat dries out and cracks caulk faster than you'd expect. Run your finger along the caulk lines - if it's hard, cracked, or pulling away from the surface, it's time to recaulk. This is one of the most cost-effective maintenance tasks you can do.
Don't Forget the Deck
Wood decks and fences take a beating in our climate. Look for graying wood, splintering, or areas where the stain has worn away. A fresh coat of quality deck stain protects the wood and keeps your outdoor spaces looking sharp. The best time to stain is spring or fall when temperatures are moderate - not during a 105-degree July afternoon.
Consider Light Colors
If you're planning a repaint, remember that lighter colors reflect more heat than dark ones. This isn't just about energy bills (though it does help) - it also reduces thermal stress on your paint and siding. That southwest-facing wall that gets afternoon sun? A dark color there will fade and deteriorate much faster than a lighter shade.
Schedule Your Projects Smart
The ideal painting weather is 50-85 degrees with low humidity. In San Antonio, that means spring and fall are prime painting season. If you're thinking about an exterior project, don't wait until July when it's too hot for paint to cure properly. Plan ahead and get on a painter's schedule early.
