Wood rot is a silent intruder that can compromise your home’s structural integrity before you even notice a problem. Unlike a leaky faucet or a cracked window, rot doesn’t always announce itself. Instead, it hides beneath paint, behind siding, and under your feet. Catching it early can save you thousands in repairs. Here’s where and how to look.
Start Where Wood Meets Moisture
Moisture is the key ingredient for rot, so the best place to start is anywhere wood and water interact. Take a slow walk around your home and check these critical areas:
- Decking and Porch Supports: Probe beams, joists, and steps with a screwdriver. If the wood is soft or crumbles easily, rot has already set in.
- Window and Door Frames: Even well-painted trim can hide decay. Pay attention to lower corners where rainwater can collect.
- Siding and Fascia Boards: Inspect areas near the roofline, especially where gutters may have overflowed or clogged in the past.
- Basement and Crawl Space Joists: Use a flashlight to check exposed wooden beams for discoloration, warping, or a musty smell—signs of hidden rot.
Check the Unexpected Places
Some of the worst rot damage occurs in places homeowners rarely think to look. Don’t overlook these spots:
- Underneath Sinks: Leaky pipes can quietly feed rot in cabinetry and subfloors.
- Attic Rafters: A past roof leak may have left behind more than just water stains.
- Fences and Gates: If the wood is in direct contact with the ground, rot may already be at work.
- Garage Doors and Frames: These areas often suffer from splash-back water damage.
How to Confirm Wood Rot
Not all discoloration or warping means rot. Here’s how to be sure:
- Press and Probe: Use a screwdriver to gently push into suspected areas. Healthy wood resists; rotting wood sinks in.
- Look for Fungal Growth: White, yellow, or brown patches on wood can be signs of active decay.
- Check for a Musty Odor: Rotting wood often carries a distinct, damp smell.
Next Steps
If you find wood rot, don’t ignore it. Small areas of damage can sometimes be treated with wood hardeners or fillers, but extensive decay requires replacement. More importantly, address the moisture source to prevent future problems.
By staying vigilant, you can protect your home from one of nature’s most persistent threats. A little attention today can prevent major repairs down the road.
