Deck Safety Inspection Checklist Before Summer
A homeowner-friendly walk-through you can do before you invite anyone over.
Why inspect before summer
Winter is hard on decks. Snow load, freeze-thaw, and moisture all show up in spring. A ten-minute inspection now beats a bad surprise in July.
Check the deck boards
Walk the deck slowly. Feel for soft spots. Look for cupping, splitting, or exposed fasteners.
Check railings and stairs
Push on railings. Test each stair. Look for wobble at the posts and gaps at the connection points.
Look for sagging or movement
Sight along the deck edge. A sag can be minor or a sign of joist or beam trouble.
Inspect fasteners and connectors
If you can safely look at the framing from below, check joist hangers and ledger bolts for rust.
Check ledger and flashing
Where the deck meets the house is the highest-risk area on most decks. Water stains and missing flashing deserve a professional look.
Look for water damage
Dark staining, soft wood, and mushrooms are all moisture signs.
When to call a professional
Any structural movement, ledger concern, or loose railing is worth an inspection.
