Decks & Fences
10 Signs Your Deck Needs Repair or Replacement
Soft boards, wobbly railings, rusted hardware, the warning signs that decide whether you need a repair or a full replacement.
What to look for
Decks in Ontario take a beating from snow, ice, UV, and humidity. Most decks last 15-25 years, but warning signs show up much earlier, and catching them early is the difference between a $400 repair and a $15,000 rebuild.
The 10 signs
1. Soft, spongy, or rotted boards, especially near posts and joist hangers.
2. Wobbly or loose railings that move when you lean on them.
3. Rusted nails, screws, joist hangers, or post anchors.
4. Posts that are cracked, leaning, or rotting at ground contact.
5. Ledger board pulling away from the house or missing flashing.
6. Cracked, splintered, or cupped boards across large areas.
7. Mushrooms, moss, or persistent black mildew on the surface.
8. Stair stringers that flex or have cracked treads.
9. Sagging, bouncing, or uneven sections of the deck surface.
10. A deck that is older than 20 years and has never had structural inspection.
Repair or replace?
If the structure (joists, beams, posts, ledger) is sound and the issues are cosmetic or limited to surface boards, you are almost always better off repairing.
If the framing is rotted or the deck was built without modern code-required hardware, replacement is the safer and often cheaper long-term choice.
