What to Do Immediately After a Pipe Bursts

Burst Pipes Are a Time-Critical Emergency

In Austin, burst pipes most commonly occur in two situations: during the rare but severe winter freezes that drop temperatures below 20°F, and as the result of aging galvanized or CPVC supply lines that suddenly fail without warning. When a half-inch supply line ruptures at normal household water pressure, it can release more than 50 gallons per minute — flooding an entire room in minutes and reaching multiple floors if the break is in an upper-level bathroom or laundry room.

What you do in the first 15-30 minutes after a burst pipe determines whether you are dealing with a manageable restoration project or a catastrophic structural loss. Here is the exact sequence of steps our IICRC-certified technicians recommend.

Step 1: Shut Off the Main Water Supply — Immediately

Every minute you delay costs gallons of additional flooding. Your home's main water shut-off valve is typically located where the water line enters the home — in Austin homes, this is often in the garage, a utility closet, or near the water heater. Turn the valve clockwise (right) until it stops. If you have a ball valve, rotate the handle 90 degrees until it is perpendicular to the pipe.

If you do not know where your main shut-off is, locate and test it before an emergency happens. For older Austin homes in areas like Hyde Park or Brentwood that may have original plumbing, consider having a plumber install a newer ball-style shut-off that is easier to operate under stress.

Step 2: Kill the Electricity to Affected Areas

Water and electricity create a lethal combination. Before entering any flooded area, go to your breaker panel and switch off the circuits for any rooms that have standing water. In a severe flood, consider shutting off the main breaker entirely. Do not enter a room with standing water if you cannot confirm the power is off, and if water is near your electrical panel itself, call 911 and exit the building — do not touch the panel.

Step 3: Document Everything Before You Move Anything

Your insurance claim depends on thorough documentation. Before you move furniture, throw away damaged items, or begin any drying efforts, take a complete video walkthrough of every affected room. Capture ceiling staining, standing water depth (use a ruler for reference), damaged contents, and any visible pipe damage. This documentation is critical if there is any dispute about the extent of damage.

Step 4: Remove Standing Water If It Is Safe to Do So

If you have a wet/dry shop vacuum, use it to remove standing water from hard floors. Soak up water from carpet with large towels. Open windows and doors to improve air circulation if outdoor humidity is below 60% (check your weather app). However, do not use standard household fans to blow air over flooded areas — circulating warm, humid air can actually accelerate mold growth by spreading moisture into dry areas of the home.

Step 5: Call a Professional Water Damage Restoration Company

By this point, you've stopped the source and taken basic safety measures. Now you need professionals. Even if the standing water appears to be mostly gone, the structural materials — subfloor, framing, drywall, insulation — have absorbed significant moisture that is invisible to the naked eye. Without industrial drying equipment (high-capacity dehumidifiers and air movers) operating for 3-5 days, this residual moisture will generate mold growth within 24-72 hours.
