Frozen Pipe Burst Response Checklist — What to Do Right Now

The main shutoff is typically near the water meter — in the basement, crawl space, utility closet, or at the street. Turn the valve clockwise until it stops. If you don't know where yours is, look for a round metal cover in the yard near the sidewalk (street-side shutoff) and use a meter key or adjustable wrench. Every second counts — locating this valve after a burst is too late for minimal damage.

After shutting off the main valve, open the lowest faucets in your home (basement or first-floor sinks) and flush toilets. This drains the water still sitting in the pipes and relieves pressure that could cause additional bursts at other frozen points.

With the water supply off, the water heater can overheat and damage itself. For gas heaters, turn the thermostat to pilot or off. For electric heaters, flip the breaker. This also prevents hot water from adding to the flooding if the hot water line is affected.

If you can reach your electrical panel without walking through standing water, flip the breakers for affected rooms. If the panel is in a flooded area, do not touch it — call an electrician or your utility company to disconnect power remotely. Water conducts electricity through floors, walls, and any metal surface.

Even after turning off breakers, outlets and switches in walls that absorbed water can hold charge in saturated wiring. Use flashlights, not overhead lights. Do not plug in fans or vacuums in affected rooms until an electrician confirms the circuits are safe.

A shop vac is the fastest tool for residential flooding. If you don't own one, mops and towels work for shallow water. Push water toward floor drains if available. For significant flooding (more than an inch of standing water), call a water damage restoration company — they have truck-mounted extractors that remove water 10x faster.

Wet carpet padding is ruined within hours. Solid wood furniture sitting in water will warp and stain permanently. Get items off the wet floor and onto dry surfaces or into unaffected rooms. Prop wet furniture on aluminum foil or wood blocks to prevent staining on dry floors.

Once an electrician confirms circuits are safe — or if you're using outlets in unaffected rooms with extension cords — set up fans and a dehumidifier. Drying must begin within 24 hours to prevent mold. Open windows if outdoor temperature and humidity allow it.

Capture the water level on walls (look for waterlines), the burst pipe location, damaged flooring, and any affected belongings. Record video panning from the burst pipe to each damaged room. Adjusters rely on this evidence — once you clean up, the severity is impossible to prove.

Open a note on your phone: record when you discovered the burst, the outside temperature (screenshot a weather app), where the pipe failed, and every action you took. Insurers look for evidence that you responded promptly to mitigate damage — a timeline demonstrates that.

Most policies require prompt notification. Describe the event, reference your documentation, and ask about coverage for both the pipe repair and the resulting water damage. Emergency mitigation costs (water extraction, fans, dehumidifiers) are typically covered — keep receipts.

An emergency plumber can typically respond within 2–6 hours. The repair involves cutting out the burst section and soldering or crimping a new fitting. Expect to pay $200–$600 for a straightforward burst repair, or more if the pipe is inside a wall and requires opening drywall to access.

If water reached multiple rooms, soaked into subfloor, or saturated drywall more than 2 feet up the wall, professional drying is critical. Restoration companies set up industrial drying equipment and monitor moisture levels over 3–5 days. Starting within 24 hours of the burst significantly reduces mold risk and total remediation cost.

If one pipe burst, others in the same area are at risk. Ask the plumber to check all exposed pipes in unheated spaces — crawl spaces, garages, attics, and exterior walls. Adding pipe insulation or heat tape to vulnerable sections costs $50–$200 and prevents a repeat event.
