What Causes Wood Rot? (And How to Stop It)
What Exactly is Wood Rot?
How wood rot takes hold wood rot is basically what happens when your exterior wood stays damp for too long. When old paint cracks or caulking pulls away, rain and moisture seep into the wood. In San Antonio, our humid summers and wet springs make it easy for moisture to get trapped, causing the wood to soften and eventually fall apart.
We most commonly find rot in these "hot spots":
-
Windows: The sills and the trim around the glass.
-
Doors: The very bottom of door frames where water pools.
-
Roofline: The flat boards (fascia) behind your gutters.
-
Siding: Where boards overlap or meet at the corners.
-
Porches: Posts and railings that sit out in the rain.
The tricky part? Rot is often a "hidden" problem. It hides under a layer of peeling paint or old caulk, and you might not even know it's there until we take a closer look during your inspection.
Early Warning Signs of Wood Rot Damage
Common Signs Your Wood Needs Attention Catching rot early can save you thousands in repairs. Keep an eye out for:
-
Soft Spots: Wood that feels "mushy" instead of solid.
-
Flaking Paint: Especially paint that seems to "pop" off the wood shortly after being painted.
-
Separating Seams: Visible gaps forming where two boards meet (like at the corners of your house).
-
Warping or Swelling: Siding boards that look like they are bulging or pulling away from the wall.
-
Stained Surfaces: Discoloration that looks like water-soaking, even when it hasn't rained recently.
Pro Tip: If you notice a "soft spot" near your window or door, don't just caulk it! Trapping that moisture inside will only make the rot spread faster.
Why Wood Rot is a Common Problem in San Antonio
Wood rot is a slow process that happens when your home’s "seal" starts to wear out. In San Antonio, our intense sun can bake your paint and caulk until it cracks, leaving the wood underneath unprotected. Once moisture gets in, it stays there.
The most common causes we see are:
-
Old, Dried-Out Caulk: When caulking gets brittle and pulls away from the house.
-
Unsealed Gaps: Small openings around windows and doors that act like a funnel for rain.
-
"Tired" Paint: When paint has thinned or flaked, it no longer sheds water.
-
Bad Drainage: Gutters that overflow or water that pools near the foundation.
-
Wrong Sprinkler Aim: Grass-watering systems that accidentally "power wash" your siding every morning.
-
Waiting Too Long: Putting off small touch-ups until they become big repair bills.
Why You Shouldn’t Ignore Wood Rot
The Cost of Waiting Yes—wood rot is one of those problems that only gets more expensive with time. What looks like a tiny soft spot today can quickly turn into a major project.
If left alone, rot can:
-
Creep Under the Surface: It often spreads behind your siding where you can't see it, damaging the "bones" of your home.
-
Make Windows & Doors Stick: Rotting frames can shift, making it hard to open your windows or lock your doors properly.
-
Invite Unwanted Guests: Soft, damp wood is a neon sign for termites and pests—a common headache here in San Antonio.
-
Stall a Home Sale: Wood rot is one of the first things a home inspector will flag, which can move a "sold" sign back to "for sale" very quickly.
-
Multiply the Repair Bill: Replacing a single trim board is affordable; replacing a wall stud or a window frame is a different story.

Should You Fix It Yourself? DIY vs. Pro Wood Repair
While a handy homeowner can fill a small nail hole, true wood rot is a different beast. In San Antonio, surface patches often fail because they trap moisture inside. We recommend calling in a professional when:
-
The Location is Critical: Rot around window sills or door frames can quickly leak into your home’s interior walls.
-
The "Hollow" Sound: If the wood sounds empty when tapped or gives way under light pressure, the damage is deep.
-
It's a "Repeat Offender": If you’ve painted that spot before and it’s already peeling again, there’s an underlying moisture issue.
-
Height is a Factor: For second-story trim or fascia boards, it’s safer and faster to let a pro with the right ladders handle it.
-
You Want a Permanent Fix: If you’re looking for a solution that lasts years—not just until the next rainy season.
Exterior Wood We Frequently Replace
Full Siding Panels
Expert siding panel replacement. Full-size siding panels—commonly 4x8, 4x9, or 4x10 sheets—come in a wide variety of textures and materials. Finding the exact match for your home is often difficult at big-box stores, but with over a decade of experience in San Antonio, we have the local sources to find the right material for a seamless match.
We don’t just swap out the wood; we do it right. This includes installing a high-quality vapor barrier, a critical protection step that many contractors skip. This barrier is what keeps the Texas humidity from reaching your home’s interior framing.
You can count on us for an honest assessment. We’ll never pressure you into a full replacement if a targeted repair will do the job.
Horizontal Lap Siding
Mastering Lap Siding Repair & Sourcing Lap siding comes in a vast range of materials and profiles—from modern engineered wood (available in single, double 5, and triple 4 styles) to classic beveled cedar and smooth board finishes. Because some older siding profiles are no longer in production, finding a match for a repair can be a major hurdle for most homeowners.
With over a decade of experience in San Antonio, we’ve built the local knowledge and sourcing network needed to find even the most difficult-to-match siding. We don’t just focus on the look; we focus on the "bones." This includes using high-quality OSB sheathing and installing a proper vapor barrier—essential steps for protecting your home from the South Texas humidity that many other companies skip.
At Home Pros Painting, our reputation is built on honesty. We’ll provide a dependable assessment of your siding and will never pressure you into a full replacement if a targeted, high-quality repair is the better solution.
Window & Door Trim Replacement
The trim around your doors (often called brickmold) and windows is your home's first line of defense against moisture. We offer a variety of replacement options including pine, cedar, engineered wood, and PVC to match your home's style and durability needs.
Why Material Choice Matters:
-
PVC: Perfect for "wet zones" near the ground or under leaky gutters because it will never rot.
-
Cedar & Engineered Wood: Great for matching the natural look and texture of your existing siding.
-
The Painting Factor: We know which materials take paint beautifully and which ones (like pressure-treated wood) should be avoided for a high-quality finish.
After 12 years of restoring San Antonio exteriors, we have the expertise to do the job right the first time. You can trust Home Pros Painting for top-notch craftsmanship and an honest, no-pressure assessment of your home’s trim.
Pricing Factors: What Goes Into Your Wood Repair Quote?
What Determines the Cost of Your Repair? Every home in San Antonio is different, and wood rot can be unpredictable. To give you an accurate and fair estimate, we look at four main factors:
-
Extent of the Damage: Is it a small surface spot or deep-seated rot that has reached the structural "bones" of the wall?
-
Repair vs. Replace: Can the area be expertly restored, or is the damage severe enough that a full material replacement is the only way to guarantee a long-lasting fix?
-
Location & Accessibility: Ground-level trim is a quick fix, while high-reaching fascia boards or chimney siding require specialized ladders and safety equipment.
-
The "Hidden" Factor: Wood rot is often like an iceberg—most of it is hidden under the paint. We assess how much "unseen" moisture damage might be lurking behind the surface.
While a minor fix is straightforward, widespread rot requires a more involved solution. The best way to get a clear picture of your investment is through a professional on-site inspection.
