Deck repair and rebuilds
Some decks need a few boards. Others look fine on top but are failing underneath. Here's how a builder sorts out which one you have.
Decks fail slowly, then sometimes all at once. Water that sits on boards, gets behind the ledger, or pools around posts does most of the damage, and freeze-thaw cycles speed it up. A careful look underneath is the only way to know what you're dealing with.
What does a builder check?
- Ledger. Is it bolted, not just nailed, to the house? Is there flashing above it? Is the wood behind it soft?
- Footings and posts. Have footings heaved or tipped? Are posts sitting on loose blocks or rotting at the base?
- Joists and beams. Any sagging, splitting or rot, especially at the ends and under board seams?
- Hardware. Rusted hangers, missing bolts and fasteners that weren't rated for treated lumber.
- Boards, stairs and railings. Soft spots, splits and loose guards.
Repair or rebuild?
If the frame and footings are sound, replacing boards, stair treads or a railing section is usually a straightforward repair. If the ledger is rotted, footings are heaving, or much of the framing is soft, rebuilding is often safer and better value than patching. A full rebuild is also the chance to get footings to the right depth and add features you've wanted. Larger repairs and rebuilds may need a permit, so ask the builder.
Freeze-thaw damage
Older decks around Rapid City were sometimes built with footings that were too shallow or with posts set on blocks. Over a few winters, the ground can lift them unevenly, and the deck starts to slope, rack or pull away from the house. Fixing that usually means new footings dug to the proper depth, not just shimming the posts.
Hail and storm damage
Large hail can split dry wood boards, crack railing caps, and damage pergola tops and deck furniture. If a storm hit, take photos and check with your insurer before repairs begin.
Is my deck dangerous?
A railing that moves, stairs that rock, or a deck that's pulling away from the house are safety problems. Keep people off the affected area until it's been checked, and don't host a crowd on a deck you're unsure about.
The builder prices the job after seeing the site, measuring, and talking through materials and layout with you. We don't quote prices, and a number given over the phone is only a rough starting point.

Common questions
Can you just replace the boards on my deck?
Often, if the framing and footings are sound. A builder should check the ledger, joists and posts first so new boards don't go on a failing frame.
Does homeowners insurance cover hail damage to a deck?
It depends on your policy and deductible. Take photos after the storm and ask your insurer before work starts.
