Your home’s exterior paint does more than keep things looking sharp. It’s your first line of defense against weather, protecting wood from moisture, sun damage, and insects. Neglect it, and a minor maintenance issue can quickly turn into an expensive structural problem.
Why This Matters: The Real Costs of Ignoring It
- Wood rot is costly.
On average, repairing or replacing rotted exterior wood like fascia boards, trim, or siding costs $1,500 to $5,000. Larger sections or hidden structural damage can drive costs even higher. - Insurance usually doesn’t pay for it.
Most homeowners policies treat rot as preventable maintenance, not a sudden accident. That means you’ll pay out of pocket. - Rot is often hidden.
By the time you see peeling paint or soft wood, moisture could have been working its way in for months or even years.
How to Keep Paint Protecting Your Home
1. Inspect at least once a year
Do a walk-around every spring and after major storms. Look for peeling or blistering paint, cracks along seams, or bare wood. These are early signs your paint is failing.
2. Touch up problem areas promptly
If you see small chips or peeling spots, don’t wait. Scrape, prime, and repaint to seal out moisture before it penetrates the wood.
3. Keep surfaces clean
Dirt, mold, and mildew can degrade paint. Rinse siding with a garden hose or wash gently with a soft brush and mild detergent once a year. Avoid harsh pressure washers that can damage paint.
4. Check and replace caulk
Inspect caulk around windows, doors, and joints. Cracked or missing caulk allows water to seep behind paint and into the wood. Re-caulk where needed.
5. Repaint before it’s too late
Most quality exterior paints last 5 to 8 years, depending on your climate and sun exposure. Waiting until large areas are flaking means water is likely already penetrating the wood.
Maintenance vs. Repair: A Look at Real Costs
| Service | Typical Cost |
|---|---|
| Small paint touch-ups | $100 – $300 |
| Full exterior repaint | $3,000 – $8,000 |
| Replacing rotted trim/siding | $1,500 – $5,000+ |
Investing a few hundred dollars in preventative painting and sealing can save you thousands in future wood repairs or replacements.
Bottom Line
Exterior paint is more than just curb appeal. It’s a vital barrier that protects your home’s wood from moisture and rot. Stay ahead of costly repairs by keeping it well-maintained — your wallet and your house will thank you.
