Replace or Repair? 7 Signs Your Siding Is Past Its Prime

Most siding failures start within 3 feet of the ground or near a roof-wall junction. Splash-back, sprinkler overspray, and missed kickout flashing all dump water exactly where the siding is most vulnerable.

If your damage is concentrated in one area, you're often looking at a localized repair plus a flashing fix — not a full replacement.

1. Paint peeling in sheets, not flakes — moisture is coming from behind the board.

2. Soft spots when you press with a screwdriver.

3. Visible gaps where caulk has failed at trim, windows, or butt joints.

4. Warped or cupped boards — common on engineered wood that wasn't sealed on the cut ends.

5. Mold or staining that returns within months of cleaning.

6. Interior signs: blistered drywall paint, musty smells, or stained baseboards on exterior walls.

7. A siding system that's simply at the end of its life — most masonite, T1-11, and early-generation vinyl is well past 25 years now.

Spot repairs run $400–$1,800 depending on access and finish matching. A full re-side on a typical Upstate home is $18,000–$45,000.

If your damage is in more than two areas, or you're hitting age-related failure across the whole house, repairs become a losing game — you'll spend $5K patching a house that needs $25K of work.
