Safely Re-Entering a Damaged Home
The Post-Disaster Recovery chapter puts re-entry safety first, "before" the claims process, since none of that matters if entering the structure itself causes an injury. This guide is the actual walkthrough: what to check outside first, the gas and electrical checks, the structural red flags that mean turn around, and the order to move through the house once it's safe to go in. For the insurance and claims process that comes after, see Filing Claims After a Disaster.

Before you go anywhere near the door: the exterior check
Walk around the outside of the property first. Damage visible from outside is often a sign of a bigger problem inside.
- Downed or damaged power lines. If you see one, don't step in any nearby puddle or standing water, stay well back, and report it to the power company rather than moving it yourself.
- The smell of gas, or a hissing or blowing sound. Don't investigate further, see the gas section below.
- Foundation cracks, walls that are out of plumb, a sagging roofline, or ground fissures.
- After a wildfire specifically: ash pits, charred trees, and hot embers, which can stay dangerously hot for days.
Don't enter if you see floodwaters, significant visible damage and debris, or if a structural inspector or contractor hasn't yet confirmed the building is sound.
Gas: leave immediately if you detect it
- If you smell gas or hear a hissing or blowing sound, don't turn on lights, don't use a phone or anything electrical inside, and don't investigate the source.
- Open a window if you can do so quickly and safely, then leave the property immediately.
- Turn off the gas at the main valve from outside if you can do so safely; the exact shutoff steps are covered in Fire-Starting & Generator Safety.
- Call the gas company or fire department only after you're a safe distance away.
Electrical hazards
If any wiring looks damaged, or anything electrical has been wet, turn off power at the main breaker or fuse box rather than risk it. Have a licensed electrician inspect the system before restoring power to a home that's had any water intrusion or visible wiring damage.
Structural red flags: turn around if you see these
| Sign | Why it matters |
|---|---|
| Any indication of collapse or foundation movement | The structure may not be able to bear its own weight, let alone yours |
| Cracked chimney mortar | A fire and carbon monoxide hazard even if the rest of the home looks fine |
| Cracks in the roofline, structural beams, or foundation | Signs the building's load-bearing capacity has been compromised |
| "Stair-step" cracks in drywall, especially after an earthquake | A classic sign of structural shifting, not just cosmetic damage |
Once it's genuinely safe to go in
- Wear real PPE: sturdy closed-toe boots, work gloves, and an N95 or better respirator; after a house fire specifically, upgrade to a P100 if you have one, ash carries finer particulates and can include heavy metals and chemical off-gassing that an N95 isn't rated to filter.
- Use a battery-powered flashlight, never a candle or open flame, in case of an undetected gas leak.
- Leave children with a relative or friend for this first inspection; the site may genuinely be unsafe for them, and seeing the damage firsthand can be upsetting.
A home built before 1980 may contain asbestos, and damage can turn it into an airborne hazard
Move through the home in this rough order:
- Stairs and banisters: test stability before putting your full weight on them.
- Windows and doors: look for jamming or cracks radiating out from the corners, a sign of structural movement.
- Appliances: check connections; anything that got wet needs to dry out completely before it's powered on.
- Attic: check for smoke or fire damage, especially after a wildfire.
- Basement: inspect for cracks that could indicate a structural problem, not just water damage.
- Stay alert for objects that could fall from cabinets or shelving that shifted during the event.
Water, sewage, and mold
- Turn off the main water valve if any pipes are visibly damaged.
- Don't flush any toilet until you've confirmed the sewage line itself is intact; flushing into a broken line can back up into the house.
- Assume tap water is unsafe to drink until local authorities confirm otherwise, even if it looks clear; see Water Purification if you need to treat it yourself in the meantime.
- Wait until floodwater outside the house has receded before you start pumping, water still standing against the foundation is bracing it against saturated soil pressure from the outside, and removing the inside water first, before the outside water has dropped, is what actually causes the collapse. Once it's safe to start, pump out a flooded basement or crawlspace gradually, roughly one-third of the water per day, rather than all at once, for the same reason.
- Watch for a musty smell in the days after, an early sign of mold growth in wet drywall, carpet, or insulation.
Tip
Race the 24-48 hour window, not just watch for the smell afterward
Document before you clean anything up
Take photos and video of every damaged area before repairs or cleanup begin, and separate debris into yard waste, building materials, and regular trash as you go. This is the exact evidence the claims process depends on; see Filing Claims After a Disaster for what happens next.
