Quick answer
Emergency water damage restoration is a same-day response: a crew arrives — typically within one to four hours of the call for a true 24-hour company — extracts standing water, removes materials that cannot be saved (wet carpet pad, saturated drywall), and sets air movers and dehumidifiers so the structure dries over the following three to five days. Before they arrive: shut off the water at the fixture or the main, kill power to any wet circuits, move what you can out of the water, and photograph everything. Speed matters because mold can establish within 24–48 hours of materials getting wet, and because sudden, accidental water damage is usually covered by homeowners insurance while damage left to sit often is not. Emergency service costs more than a scheduled job — after-hours dispatch and extraction are billed at a premium — but for a covered loss the insurer generally pays the mitigation cost, since the policy requires you to act promptly to prevent further damage.
The First 30 Minutes Are Yours
No crew arrives faster than you can walk to the shut-off valve. Before you call anyone:
- 1Stop the water. Fixture valve first (under the sink, behind the toilet, at the washing machine), then the main if that doesn't do it — where to find it and how to turn it. A water heater has its own cold-water inlet valve on top.
- 2Kill power to wet areas at the breaker panel, if you can reach the panel without standing in water. Do not touch outlets, switches or appliances that are wet.
- 3Get things out of the water. Furniture up on foil or blocks, rugs out, boxes off the floor. Wet cardboard and paper start staining and molding within a day.
- 4Document before you move anything else. Photos and video of the source, the standing water, every wet room, every damaged item. This is the record your claim will rest on — how to document water damage for insurance.
Then make the call. Not tomorrow — the reason emergency restoration exists is that the first day is the only day the damage is still reversible.
What "Emergency" Actually Buys You
A scheduled restoration visit and an emergency one do the same work; the emergency one does it before the water has soaked into framing, wicked up drywall and started growing mold. The clock:
| Time since the water | What's happening in the house |
|---|---|
| 0–2 hours | Water spreads across floors, into carpet pad, under baseboards, into the bottom of drywall |
| 2–24 hours | Drywall and wood absorb water; finishes swell; metal starts corroding; odor begins |
| 24–48 hours | Mold can establish on wet drywall paper, wood and carpet pad (EPA/CDC threshold) |
| 3–7 days | Established growth; wet materials become removal rather than drying |
The IICRC S500 standard that restoration crews work to is built around getting materials back below the moisture level that supports growth as quickly as possible. Every hour of standing water adds materials to the "remove" column and takes them out of the "dry" column — and removal is what drives cost.
Hour by Hour: What the Crew Does
The call. A real 24-hour company answers with a person who asks what the source is, whether it's stopped, how many rooms, and what kind of water — clean supply water, grey water from an appliance, or sewage — because that decides the equipment and PPE they bring. They give you an arrival window. One to four hours is normal; the benchmark the national franchises advertise is contact within an hour and a crew on site within four.
Arrival — the first hour. A technician walks the loss with you, confirms the source is stopped (or gets a plumber moving), checks power and safety, and starts moisture mapping with a meter and often a thermal camera to find how far the water travelled behind the surfaces. They photograph everything again, for their file and your claim. You should get a written or emailed scope and an authorization form before work starts; read the pricing basis before signing.
Extraction — hours one to three. Standing water comes out with truck-mounted or portable extractors; carpet is extracted with weighted tools that pull water through the pad. Water that can be extracted today is water that doesn't have to be dried out of the structure over the next week.
Removal of what can't be saved — same visit. Saturated carpet pad almost always comes out (it's cheap and it never dries). Drywall wicks water up from the floor, so a "flood cut" — removing the bottom 12–24 inches — is common when the wall has been wet for more than a few hours or the water was not clean. Baseboards come off so the wall can dry. Wet insulation comes out. With clean water caught fast, carpet, hardwood and drywall are often saved; with grey water or a delay, less is.
Drying setup — end of the first visit. Air movers along the wet walls and floors, dehumidifiers sized to the room, sometimes floor-drying mats for hardwood and injectidry systems for wall cavities. Equipment stays for three to five days on a typical loss; the crew returns daily to take moisture readings and reposition. The full restoration process covers what follows, and how long it takes sets expectations by room and material.
Antimicrobial and odor. Where water was not clean, or drying was delayed, affected surfaces get an antimicrobial application after extraction. This is not a substitute for drying and it is not "mold remediation" — if growth is already established, that is a separate scope that follows the remediation process.

What It Costs, and Who Pays
Emergency work is priced above scheduled work: after-hours dispatch, emergency extraction and the first day of equipment carry a premium, and the per-day equipment charges run until readings come back to dry. Most restoration companies price from the same Xactimate line items insurers use, which is why a covered loss rarely turns into an argument about the mitigation bill. The water damage restoration cost guide has the ranges by job size.
On coverage: sudden and accidental discharge — a burst pipe, a failed supply line, an appliance leak — is covered by most standard homeowners policies, and those policies obligate you to mitigate promptly, which the emergency call satisfies. Damage from long-term leaks, neglected maintenance and rising surface water is generally excluded. The Insurance Information Institute puts the average water damage and freezing claim at roughly $14,000, which is a fair picture of what a typical covered loss ends up costing once repairs are included. Does homeowners insurance cover water damage covers the distinctions, and the claim guide walks the process — call the restoration company first, the insurer second, and do not wait for an adjuster to start drying.
Real 24-Hour Company or a Call Center?
The phone number on a search ad can belong to a local crew or to a lead-routing service. Questions that sort them:
- "What's your arrival window tonight?" A dispatcher for a real crew gives a number. A call center says someone will call you back.
- "Who is coming — your employees or a subcontractor?" Either can be fine; you want to know whose name is on the authorization.
- "Are you IICRC certified for water restoration (WRT), and who is the lead technician?" The certification is the industry baseline.
- "What is the pricing basis, and will I get a scope in writing before equipment goes in?" Yes is the only acceptable answer.
- "Do you bill my insurer directly?" Common and convenient; you still want to see the invoice.
Licensing varies: many states license restoration under general contracting, and Texas and Florida additionally license mold work — relevant if the loss has already grown mold. How to choose a water damage restoration company goes deeper on vetting when you have more than ten minutes.
When It Is Not an Emergency
A small clean-water spill on tile you have already mopped, a slow drip you have caught early and dried with fans — those are not restoration calls. The threshold for calling: water that has reached carpet pad, drywall or a subfloor; any water you couldn't get up within a few hours; any grey or black water (appliances, sewage, outside water); water that has gone under a floor or into a wall cavity where you can't dry it; or a loss you intend to claim, where a professional's moisture log is the evidence. If you are unsure, call and describe the loss — a real restoration dispatcher will tell you whether it needs a crew tonight or a fan and a follow-up.
If You Are Reading This With Wet Floors
Shut the water. Kill the power to the wet rooms. Photograph it. Call. The order matters less than the speed — and the speed matters because the difference between a dried house and a rebuilt one is measured in hours, not days.
