Flooded basement? Your first 10 minutes decide the bill.
Water mitigation crews say the difference between a $500 dry-out and a $25,000 gut-job is usually the first hour.
Follow this exact order and you'll cut your losses — sometimes by thousands — and never hand your insurer a reason to deny the claim.
These are the steps mitigation crews themselves run; the math behind the cleanup bill is in our cost guide, linked below.
The 10-minute plan (do them in this order)
- Kill the power to the basement. Don't wade in until the breaker for that circuit is off — water + electricity is the one truly dangerous thing in this room. If the panel itself is wet or underwater, skip the basement and call the utility.
- Find and stop the source. Burst supply pipe → main shutoff (know yours before the next one). Sump pump failed → check the breaker / battery backup first. Sewage backup → stop running water in the house entirely. Rainwater through the floor → nothing to stop it yet; move to protecting belongings.
- Photograph everything before you touch anything. Wide shots of each flooded room, close-ups of damaged items with the waterline visible, video walk-through. Insurers accept photos; they dispute memories.
- Move what you can, raise it off the floor. Electronics, wooden furniture legs, documents, rugs. Don't carry anything heavy through water you can't see the bottom of.
- Call for professional extraction within the hour. Mold colonizes wet drywall and carpet padding within 24–48 hours — the sooner fans and dehumidifiers run, the smaller the job. See our emergency matching page for how to get someone out today.
What NOT to do
- Don't mop your way out of a Category 2/3 (grey/sewage) flood with bare hands — that water carries bacteria; it's a PPE job, not a towel job.
- Don't rip out wet drywall yourself before the adjuster sees it — document first, demo second.
- Don't run a normal household shop-vac on inches of water; it's rated for puddles, not events.
- Don't wait for the "slow" insurer callback to start drying — mitigation can't wait for paperwork. Photograph, then get crews started.
"What does cleanup actually cost?"
Straight answer: $500 to $10,000+ depending on area affected, water category, and what got soaked — and most of it is insurance-recoverable when the cause was sudden and internal. Full breakdown with the calculator: flooded basement cleanup cost →

Is a flooded basement the basement's fault or the house's?
Rainwater seepage and failing drains are maintenance issues (often not covered). Sudden internal failures — burst supply lines, failed sump pump discharge, appliance hoses — are covered events on most policies. The cause on your report is what decides. Full coverage explainer →
How fast can a restoration company realistically get to me?
Nightly and weekend emergencies, 1–4 hours is common in metros; small towns can be longer. When you need extraction tonight, that response time is worth more than comparing quotes — get one crew started, then compare the estimate against ours.
