Key takeaways
- Soft spots, stains and peeling paint often mean water is getting in.
- A few damaged areas can usually be repaired.
- Widespread failure suggests it is time to replace.
- An early inspection is an easy way to avoid bigger damage.
What to look for outside
Walk around the house in good light. Look for cracked, warped or buckled panels, gaps at corners and trim, loose or missing pieces, bubbling or peeling paint, dark or green streaks, rust stains, holes from pests and fading that is uneven or chalky. Also check the base of the walls and under windows, where water tends to sit.
What to check inside
Water damage often shows up inside first: stains on walls and ceilings near exterior walls, peeling wallpaper or paint, musty smells, swollen baseboards and higher energy bills. Rising bills can mean air leaks or poor insulation in the wall, not just aging siding.
Repair or replace
If damage is limited to a few spots and the wall behind is sound, repair makes sense. If damage is widespread, the siding is brittle, the color is uneven or repairs keep coming back, replacement is usually the better path. A moisture meter and a look behind a few panels help decide.
Do not wait too long
Water that gets behind siding keeps working. A small gap this season can be a rotted corner next year. Prompt repairs are almost always simpler than waiting.
