Many Wasatch Front homes still have the wood deck that came with the house. After 15 to 25 years of Utah sun and snow, it may need more than a coat of stain. Here’s the same checklist we use on a site visit.
The 7-Point Deck Check
- Ledger board: where the deck attaches to the house. Look for rot, missing flashing and proper bolts, not just nails. This is the most common failure point.
- Posts and footings: posts should sit on concrete footings, not in soil, with no rot at the base.
- Joists and beams: push a screwdriver into the wood from below. If it sinks in easily, the wood is rotting.
- Hangers and fasteners: rust, missing nails or loose connectors weaken the whole frame.
- Railings: push hard. A railing should not move. Gaps between balusters should be under 4 inches.
- Stairs: loose treads, wobbly stringers or a missing handrail.
- Deck boards: soft spots, cracks, splinters and raised nails.
Repair, Resurface or Replace?
| What you found | Usually the right fix |
|---|---|
| Worn or splintered boards, solid frame | Resurface: new boards (wood or composite) on the existing frame |
| A few soft boards or loose railings | Repair those parts, then stain or seal |
| Rot in joists, beams, posts or the ledger | Replace the deck; the frame is the expensive part to trust |
| Frame not built for composite spacing | Add joists, or rebuild if the frame is also aging |
Safety first: if the ledger or posts are rotting, or railings move, stop using the deck until it’s checked.
What It Costs

Deck Repair FAQ
How do I know if my deck is safe?
Check the ledger board where the deck meets the house, the posts and footings, joists and railings. Soft wood, rust on hangers and fasteners, or railings that move when pushed are warning signs. When in doubt, have it inspected.
Can I put new composite boards on my old deck frame?
Only if the frame is sound and built to current spacing for composite boards. Many older frames need extra joists or repairs first.
How long does a wood deck last in Utah?
Usually 10 to 20 years for pressure-treated wood, depending on sun exposure, maintenance and drainage.
