Emergency Home Services: What to Do When Something Goes Wrong Fast

Home emergencies don't wait for business hours. A burst pipe can release gallons of water per minute. A failed furnace in January is a health risk. A gas smell requires immediate evacuation, not a Google search.

The difference between a manageable problem and a catastrophic one is almost always how fast you respond and what you do first. Most new homeowners don't know what to do in the first five minutes — which is exactly when every decision counts.

This guide covers the most common home emergencies, what to do before a same-day service contractor arrives, and how to avoid the mistakes that turn a bad situation into a much worse one.

Burst Pipe or Major Water Leak

Water damage escalates quickly. What starts as a small burst pipe can soak through floors, walls, and ceilings before a plumber even arrives.

Step 1: Shut off the main water supply. In most US homes the shutoff is in the basement near the front wall, in a utility room, or a crawl space. In warm climates and Australia it's often outside near the meter. If you don't know where yours is, find it today and write it on a sticky note inside a kitchen cabinet.

Step 2: Open the lowest faucet in the house to drain remaining water and relieve pressure.

Step 3: If water is near electrical outlets or the breaker panel, turn off the main electrical breaker — only if you can reach it without walking through standing water.

Step 4: Contain damage. Buckets, towels, and moving electronics away from wet areas all help limit the cost.

Step 5: Call a plumber. Many offer 24-hour emergency service. Save a number before you need it — searching while water pours through your ceiling is not the moment for contractor research.

Do not restore water until the break has been located and repaired.

No Heat in Winter

A furnace failure overnight in cold weather can drop indoor temperatures to dangerous levels within hours, especially in homes with poor insulation or in northern climates.

Check these before calling anyone:

Filter. A clogged air filter is one of the most common causes of furnace shutdowns. The furnace overheats when it can't draw enough air and trips a safety switch. Turn the furnace off, replace the filter, wait five minutes, then try again.

Emergency switch. Most furnaces have an emergency shutoff switch that looks like a standard light switch, often mounted on the wall near the furnace or at the top of the basement stairs. If it was bumped into the off position, that's your problem.

Exhaust and intake pipes. If snow or ice has blocked the PVC pipes that vent your furnace to the outside, the furnace will shut down as a safety measure. These pipes typically protrude from the side of your house near the foundation. Clear any blockage and try the furnace again.

Pilot light (older systems). If your furnace uses a pilot light rather than an electronic igniter, it may have gone out. Your furnace manual has the relighting procedure.

If none of these resolve the problem, call an HVAC company. Many offer 24-hour service during winter. If indoor temperatures are dropping below 55°F and the heat can't be restored quickly, arrange alternative accommodation for anyone vulnerable to cold.

Gas Smell

This is the one emergency where the response is the same regardless of any other circumstances.

Evacuate immediately. Do not open windows, turn lights on or off, use your phone inside the house, or stop to gather belongings. Get everyone — including pets — out of the building.

Do not operate anything electrical or mechanical on your way out. This includes garage door openers.

From outside or from a neighbor's home, call your gas company's emergency line or 911. Do not re-enter the building until the gas company has inspected and cleared it.

Natural gas accumulates at floor level. A single spark from a light switch, phone screen, or thermostat can ignite it. The evacuation protocol exists to eliminate every ignition source before you create one.

Sewer Backup

If water is rising from floor drains, toilets gurgle when you run the sink, or sewage smell is coming from multiple fixtures, you have a sewer backup.

Stop using all water immediately. Every gallon you send down the drain makes the situation worse. Avoid contact with any water that has surfaced — sewage is biohazardous.

This is not a DIY repair. Call a plumber who offers same-day emergency service. If your home has a sewer cleanout access point (a capped pipe at ground level near the foundation), point the plumber to it when they arrive.

Roof Leak During a Storm

Do not access the roof during the storm. Place buckets in the attic under drip points. If ceiling drywall begins to bulge with trapped water, poke a small hole in the center to drain it into a bucket — this prevents the ceiling from collapsing under the accumulated weight.

After the storm, photograph all damage before any repairs begin, then contact your homeowner's insurance company. Most policies cover storm damage, and pre-repair documentation is required for most claims.

Do not hire anyone who approaches you unsolicited after a storm. Post-storm contractor fraud is common. Use a licensed local roofer you've researched in advance.

Power Outage

Check whether the outage is isolated to your home (tripped main breaker) or affects the neighborhood. If your neighbors have power, check your main breaker panel first.

If the neighborhood is out, report it to your utility company. Their outage maps often show estimated restoration times.

Generator safety: Never run a generator indoors or in a garage, even with the door open. Carbon monoxide is colorless and odorless and kills quickly. Position any generator at least 20 feet from the house with the exhaust pointing away from windows and doors.

The Real Emergency Preparation

None of these responses work well if you don't have the basics in place before the emergency happens. That means knowing where your main water shutoff is. Knowing where your gas meter shutoff is. Having a plumber, electrician, and HVAC technician's phone number saved before you need them.

The homeowners who handle emergencies well aren't lucky — they're prepared. Spending 30 minutes walking through your home to locate shutoffs and save contractor numbers costs nothing and is worth thousands the first time something goes wrong at midnight.
