What counts as a deck emergency?
Any sign that the structure — not just the surface — is failing: a gap opening between the ledger and the house, sudden sagging or a new slope, posts that lean or are cracked, railings that move freely or have broken off, stairs that shift or have collapsed, or framing damaged by a storm or fallen tree.
| What you see | What it usually means | Risk |
|---|---|---|
| Gap between ledger board and house | Ledger fasteners failing or rotted rim joist | Deck can pull away from the house — the most serious failure |
| Deck suddenly sags or slopes | Failed joist, beam, post or footing | Progressive collapse under load |
| Railing moves freely or broke off | Post anchoring or post base failed | Falls from elevated decks |
| Stairs shift, crack or separated | Rotted stringers or failed top connection | Collapse while in use |
| Post leaning or cracked | Rot at grade, frost heave or impact | Beam and joist overload |
| Tree or limb on the deck | Hidden framing and connection damage | Unpredictable — treat as unsafe |
What should you do right now if your deck is unsafe?
Get everyone off and out from under the deck, keep it closed, document the damage, and call for a structural evaluation. Call 911 first if anyone is hurt.
- 1Get everyone off the deck immediately, moving toward the house or the nearest solid exit — avoid jumping.
- 2Keep people and pets out from underneath the deck, especially elevated decks.
- 3Close off access: lock the door to the deck and block the stairs from the yard.
- 4Remove heavy loads if it is safe to do so without standing on damaged areas — grills, planters, hot tub water should wait for a professional.
- 5If gas lines, electrical wiring or a hot tub are involved, shut them off at the source if you can do so safely, and call the utility for gas.
- 6Photograph the damage from a safe distance, including the ledger, posts and any storm debris.
- 7Call for a structural evaluation before anyone uses the deck again.
What should you do after storm or fallen-tree damage to a deck?
Treat the whole deck as unsafe until it is inspected, document everything with photos, and contact your homeowner's insurance company before debris is removed if your policy may cover the damage.
Impact from a limb or tree can crack joists, split posts and loosen the ledger even when the surface looks only scratched. High winds can also pull loose railings and lift lightly fastened boards. Whether storm damage is covered depends on your policy, so ask your insurer what documentation they need. A written evaluation of the structural damage is usually helpful for a claim.
What is the difference between a temporary and a permanent deck repair?
Temporary measures make the area safe — blocking access, removing hazards and shoring the structure. Permanent repairs restore the deck to a sound, code-compliant condition and may require a permit.
| Temporary (make it safe) | Permanent (make it right) |
|---|---|
| Close off the deck and stairs | Replace failed ledger fasteners and add flashing |
| Remove fallen limbs and loose railings | Replace rotted posts, footings or joists |
| Install temporary shoring under a sagging beam | Re-anchor railing posts with blocking and bolts |
| Cover exposed house wall from rain | Rebuild stairs with sound stringers and landing |
Structural repairs often need a building permit and inspection. Your local building department decides what applies at your address.
What happens when you call about an unsafe deck?
- 1We confirm your address is in one of our covered ZIP codes.
- 2You describe what you see — which part failed, how high the deck is, and whether anyone has been hurt or utilities are involved.
- 3We arrange an evaluation of the structure and explain what can be made safe immediately and what needs a permanent repair or replacement.
Scheduling depends on location and conditions, so we don't publish guaranteed response times. Keep the deck closed until it has been evaluated.
How can you prevent a deck emergency?
Inspect the deck every spring and after severe storms, with particular attention to the ledger, railing posts, stairs and post bases — the connections where most deck failures begin.
- Probe the ledger, joist ends and post bases for soft wood each year.
- Push firmly on railings; re-anchor any that move.
- Keep gutters clean so overflow doesn't soak the ledger.
- Remove snow from decks in heavy-snow areas and avoid piling it against railings.
- Don't add a hot tub or other heavy load to a deck that wasn't designed for it.
How does deck emergencies differ across the states we serve?
Heavy snow adds load that exposes weak connections, so winter and early-spring failures are more likely in snowy states. The figure varies most between Minnesota (50) and Georgia (1).
| State | Snowfall, in / yr (median) | What it means |
|---|---|---|
| Georgia | 1 | Light snow: occasional ice is the main winter concern for deck emergencies |
| Illinois | 38 | Moderate snow: plan winter use and ice-melt for deck emergencies |
| Kansas | 14 | Light snow: occasional ice is the main winter concern for deck emergencies |
| Maryland | 29 | Moderate snow: plan winter use and ice-melt for deck emergencies |
| Massachusetts | 49 | Heavy snow: load, shoveling and ice drive deck emergencies |
| Minnesota | 50 | Heavy snow: load, shoveling and ice drive deck emergencies |
| North Carolina | 3 | Light snow: occasional ice is the main winter concern for deck emergencies |
| Pennsylvania | 22 | Moderate snow: plan winter use and ice-melt for deck emergencies |
| Tennessee | 3 | Light snow: occasional ice is the main winter concern for deck emergencies |
| Virginia | 19 | Moderate snow: plan winter use and ice-melt for deck emergencies |
| Washington | 4 | Light snow: occasional ice is the main winter concern for deck emergencies |
