If a pipe just burst in your home, here is what to do right now: shut off the main water supply, cut power to any affected rooms at the breaker panel, move valuables out of standing water, and call a plumber. Do those four things first. Everything else on this checklist — drying, documentation, mold prevention — comes after the water stops flowing. Keep reading for the full step-by-step breakdown, including the mistakes that turn a manageable repair into a five-figure restoration bill.
Step 1: Stop the Water and the Electricity
Your main shutoff valve is usually located where the water line enters the house — in a utility closet, garage, or crawl space. In many Henderson homes built on slab foundations, it sits near the water meter at the street curb inside a concrete box. Turn the valve clockwise until it stops. Open a faucet on the lowest floor to drain pressure from the lines and confirm the flow has stopped.
Once the water is off, go to your breaker panel and cut power to any room where water is present or suspected. Water and electricity share walls, subfloors, and ceiling cavities in ways you cannot see. Do not assume the water stayed on one side of a wall. If you are unsure which circuits serve the wet area, shut off the main breaker.
What you need at this stage:
- Location of your main shutoff valve (find it before an emergency, not during one)
- A flashlight
- Rubber-soled shoes or rubber boots
- Breaker panel access
Step 2: Protect What You Can in the First 15 Minutes
Standing water spreads faster than most people expect. On a hard floor, a burst supply line can push water under baseboards and into adjacent rooms within minutes. Here is how to limit secondary damage while you wait for a plumber:
- Move furniture and rugs off wet flooring. Wet carpet padding under furniture will stay saturated long after the surface appears dry, and dye from furniture legs can permanently stain carpet.
- Lift draperies off the floor and loop them over the curtain rod so they do not wick moisture upward.
- Place aluminum foil or plastic bags under furniture legs that cannot be moved — this slows the transfer of tannins and stain compounds into wet flooring.
- Photograph everything before you touch it. Walk the perimeter of the affected area and take photos from multiple angles. Your insurance adjuster will want documentation of the pre-cleanup condition.
- Mop or blot standing water with towels if you can do so safely. Do not use a standard household vacuum — only a wet/dry shop vac is safe around water.
If the leak is behind drywall rather than visible, watch for these signs: paint that is bubbling or separating from the wall surface, a soft or spongy feel when you press on drywall, a dark waterline spreading upward from the baseboard, or the sound of dripping inside the wall cavity. Hidden leaks are often worse than visible ones because the water has been traveling through insulation and framing before it shows itself.
Step 3: What NOT to Do
Some well-intentioned responses to a burst pipe make the damage significantly worse. Avoid these:
- Do not run ceiling fans or HVAC to dry the space faster. Forced air circulation before professional moisture mapping can push moisture into unaffected wall cavities and spread contamination. Your HVAC system can also distribute mold spores if colonization has already begun.
- Do not pull up wet carpet yourself unless a restoration professional has advised it. Improper removal can damage the tack strip, subfloor, and transition pieces, and may void certain insurance claims if the carrier requires documentation before materials are removed.
- Do not use electric space heaters in wet rooms. The combination of standing water and an electrical appliance is a shock and fire hazard.
- Do not assume the area is dry because the surface feels dry. Drywall can read dry to the touch while the wood framing behind it holds moisture above 19% — the threshold at which mold growth becomes likely. Only a calibrated moisture meter tells you what is actually happening inside the wall.
- Do not wait to call your insurance company. Most homeowner policies require prompt notification of a loss. Delayed reporting can complicate or reduce your claim, even if the damage itself is covered.
Step 4: When to Call a Water Damage Restoration Professional
A plumber fixes the pipe. A restoration company handles everything the water touched after the pipe broke. These are different scopes of work, and you typically need both.
Call a water damage restoration professional when:
- Water has been standing for more than an hour, or you do not know how long the pipe was leaking
- The affected area is larger than roughly 10 square feet
- Water has reached insulation, subfloor, or wall cavities
- The leak originated from a toilet, dishwasher drain, or any source other than a clean supply line (gray or black water contamination requires specialized handling)
- You smell anything musty within 24–48 hours of the event — mold can begin colonizing cellulose materials like drywall paper and wood framing within 24 to 72 hours under the right temperature and humidity conditions
Restoration crews use equipment that is not available at a hardware store: industrial air movers, refrigerant and desiccant dehumidifiers, thermal imaging cameras, and calibrated moisture meters. The drying process is not just running fans — it is a structured protocol (the IICRC S500 standard governs water damage drying) that tracks moisture readings across multiple days and adjusts equipment placement until all structural materials return to acceptable levels.
Appliance-related leaks — a supply line behind the refrigerator, a washing machine hose, a dishwasher door seal — follow the same response protocol but often involve water that has traveled under cabinets and into the toe-kick space before anyone notices it. That hidden travel distance is why appliance leak cleanup frequently requires more drying time than the visible footprint suggests.
Step 5: The Recovery Timeline — What Comes Next
Understanding what follows the emergency helps you plan and avoid being surprised by the scope of work:
- Days 1–3: Active drying. Industrial equipment runs continuously. Moisture readings are logged each day. Do not remove equipment early — incomplete drying is the leading cause of post-repair mold problems.
- Days 3–5 (or longer for thick assemblies): Final moisture verification. A technician confirms all structural readings are within acceptable ranges before equipment is removed.
- After drying is confirmed: Reconstruction begins — new drywall, insulation, flooring, paint. This phase is separate from mitigation and may involve a different contractor or a restoration company that handles both.
- Throughout the process: Keep records of every conversation with your insurance adjuster, every invoice, and every moisture log the restoration company provides. This documentation protects you if there is a dispute about scope or coverage.
In the Las Vegas Valley, the dry desert climate can create a false sense of security — surfaces dry faster here than in humid regions, which sometimes leads homeowners to underestimate how much moisture is still trapped in building materials. Low ambient humidity accelerates surface evaporation but does not speed the drying of dense materials like engineered hardwood subfloor or thick concrete board. Professional moisture verification matters here just as much as it does anywhere else.
