Look for loose sections

Wind and impact can loosen siding. Address pieces that are no longer properly secured.

Look for cracks or holes

Openings can let water and pests reach areas behind the siding.

Look for warping or buckling

Movement can result from installation issues, heat, moisture, or other problems depending on the material.

Watch for water clues

Interior stains near exterior walls, peeling finishes, or recurring moisture may point to a water-management issue, and the siding itself may or may not be the source.

Look for deterioration

Different siding materials fail differently. Wood may rot; other materials can crack, break, fade, or deform.

Repair or replace?

A localized damaged area may be repairable. Widespread deterioration may justify evaluating replacement. Find Local Siding Help
