If a pipe bursts, do these three things first: shut off the water, shut off power to any wet areas, and get drying started fast. This stops the damage from spreading into floors, walls, cabinets, and insulation.
Step 1: Shut off the main water supply
Turn off the main shutoff valve to stop the flow. If you cannot find it, look in these common spots:
- Basement wall facing the street
- Crawlspace near the front foundation wall
- Utility room near the water heater
- Garage wall near the front of the house
- Near the water meter (sometimes outside)
Step 2: Shut off electricity to wet areas
If water is near outlets, lights, appliances, or your breaker panel path, shut off power to the affected rooms at the breaker. Do not walk through standing water to reach the panel.
Step 3: Stop active dripping and contain spread
- Put buckets or pans under active leaks
- Use towels to dam water at doorways
- Move rugs, paper goods, and anything that can stain or swell off wet floors
- Pull curtains up and away from wet carpet
Step 4: Open faucets to drain remaining water and relieve pressure
After the main is off, open the lowest faucet in the home and a few higher faucets. This helps drain lines and reduces pressure in the plumbing system.
Step 5: If freezing caused it, thaw safely
If a faucet is only dripping or not running, a pipe may be frozen. Keep the faucet open while you thaw. Use gentle heat:
- Hair dryer
- Heating pad
- Warm towels
- Space heater placed safely, aimed toward the area
Do not use open flame.
Step 6: Call the right help
A plumber fixes the broken pipe. A water mitigation team removes water and dries the structure so damage does not keep growing behind walls and under floors.
If you only repair the pipe but do not dry the building materials, you can end up with swelling, warped floors, and mold conditions.
Step 7: Start drying within 24 to 48 hours
Moisture left in place is what drives mold. The goal is fast water removal and professional drying so hidden spaces do not stay wet.
Step 8: Document damage for insurance
Take photos and short videos of:
- The pipe area and nearby water
- Wet drywall and ceilings
- Flooring damage
- Water lines on baseboards
- Damaged belongings
Write down the time you discovered it and what you did to stop the water.
Step 9: Watch for hidden-water zones that get expensive
These spots often hold moisture after a burst:
- Behind baseboards and trim
- Under cabinets and vanities
- Drywall and insulation on exterior walls
- Subfloor under tile, LVP, and hardwood
- Ceiling cavities when the leak was upstairs
If those areas stay wet, damage keeps spreading even when the surface looks dry.
Why frozen pipes burst, and when it often happens
Frozen pipe damage is often a pressure problem. Ice forms a blockage, pressure builds in the trapped water between that blockage and a closed faucet or valve, and the pipe fails at a weak point. Many people discover the worst damage during a warm-up, when water starts moving again and finds the break.
FAQ
Who do I call when a pipe bursts?
Call an emergency plumber to repair the line, and call First Call Restoration to extract water and dry the structure. Fist Call rebuilds after mitigation so you only have to work with one contractor from start to finish.
How fast can mold start after a burst pipe?
The risk rises fast when wet materials stay wet longer than 24 to 48 hours. Drying quickly is the goal.
What should I do right after I shut off the water?
Shut off power to wet areas if needed, contain spread, and get drying started immediately. Then schedule plumbing repair and professional drying.
Will a burst pipe ruin my floors and cabinets?
It can. Water can wick under flooring, into subfloors, and behind cabinets quickly. Fast extraction and drying are what prevent the expensive version of this problem.
