Signs It’s Time to Replace Your Siding

Siding usually fails in predictable places: near the ground, under windows and where the roof meets a wall.

Short answer

Replace siding when problems are spread across several walls: cracked or missing boards, swelling or soft spots, rot near the ground or under windows, paint that keeps peeling in the same places, bubbles or mold, or hail damage over most of the house. Damage on one wall or a few boards is usually a repair.

What to look for

  • Cracked, dented or missing boards
  • Swollen or soft boards near the ground, at corners or under windows
  • Paint peeling over and over in the same spots
  • Bubbles, warping or boards pulling away
  • Gaps at trim, corners and around windows
  • Mold, mildew or water stains behind boards or inside walls
  • Woodpecker holes or termite damage on wood siding

Check the trim and flashing first

Many “siding” failures start at trim and flashing: a rotted window sill, failed caulk, or a roof-to-wall joint without a kickout flashing sends water behind the boards. Press a screwdriver into corner boards and sills; soft wood means water is getting in.

Repair or replace?

If the damage is limited to one wall or a few boards, a repair is usually enough. If problems are spread around the house, replacement often costs less over time. See repair or replace Hardie siding and our siding repair page.

Common questions

How do I know if my siding needs replacing?

Look for damage on several walls: cracked or soft boards, rot near the ground or windows, repeated peeling paint and gaps at trim. Damage in one area is usually a repair.

Can old siding hide water damage?

Yes. Rot in the sheathing behind the siding often only shows once boards come off.
