Home Repair Emergency Guide: What to Do Before Help Arrives

A burst pipe at 2 a.m. A gas smell when you walk through the front door. A tree limb through the roof during a storm. Home emergencies do not wait for business hours, and the actions you take in the first five to fifteen minutes can mean the difference between a manageable repair and tens of thousands of dollars in damage. This guide gives you a clear plan for every major home emergency, so you can act fast and act right.

Always verify contractor licensing and insurance in your state. Cost estimates are averages and may vary by location.

Step-by-Step Emergency Responses

Burst Pipe

Water damage costs American homeowners an average of $13,000 per incident, according to insurance industry data. Speed is everything.

Locate and shut off the main water valve. In most homes, it is near the water meter (basement, crawl space, or near the street). Turn the valve clockwise until it stops.
Open faucets to drain remaining pressure. This reduces the volume of water still in the pipes.
Turn off the water heater. If the hot-water line burst, draining continues from the tank unless you shut it off. For a gas water heater, turn the gas valve to “pilot.” For electric, kill the breaker.
Document the damage. Take photos and video of all affected areas before cleaning up. Your insurance company will need this.
Remove standing water. Use a wet-dry vacuum, mop, or towels. The longer water sits, the more damage it causes to flooring, drywall, and framing.
Call an emergency plumber. Expect after-hours rates of $150-$300/hour. The repair itself depends on the location and severity of the break.
Contact your insurance company. Most homeowner policies cover sudden and accidental water damage (but not gradual leaks or deferred maintenance).

Prevention: Insulate exposed pipes in unheated areas. During extreme cold, let faucets drip at a slow stream and keep cabinet doors under sinks open to allow warm air circulation. Seasonal Home Maintenance: Spring, Summer, Fall, Winter Checklists

Gas Leak

Natural gas leaks are life-threatening. The rotten-egg smell (mercaptan) added to natural gas exists specifically so you can detect leaks. If you smell it, act immediately.

Do NOT flip any electrical switches, light matches, or use your phone inside the home. Any spark can ignite the gas.
Leave the house immediately. Take everyone, including pets, with you.
From outside (at least 100 feet away), call 911 and your gas utility’s emergency line. These numbers should be programmed into your phone before you ever need them.
Do not re-enter the home until the gas company or fire department confirms it is safe.
Once cleared, have a licensed plumber or gas technician locate and repair the leak. Common sources include corroded fittings, damaged flex connectors on appliances, and deteriorating gas supply lines.

Prevention: Schedule a gas line inspection every 5-10 years, especially in homes older than 30 years. Install natural gas detectors in addition to your CO detectors.

Electrical Fire or Sparking

If you see sparks or flames at an outlet or panel, kill the main breaker if you can reach it safely. Do not touch the sparking device or outlet.
Use a Class C (electrical-rated) fire extinguisher. Never use water on an electrical fire.
If the fire is beyond a small, contained spark, call 911 and evacuate. Close doors behind you to slow fire spread.
After the situation is safe, call a licensed electrician for inspection and repair. The underlying cause (overloaded circuit, loose connection, damaged wiring) must be identified and fixed.

Prevention: Replace any outlet or switch that feels warm, buzzes, or shows discoloration. Install AFCI breakers in bedrooms and living areas as code requires. Electrical Safety: When to DIY and When to Call an Electrician

Roof Leak During a Storm

Place buckets or large containers under the drip. If water is running along a ceiling, poke a small hole at the lowest point to direct it into a bucket. This prevents the water from spreading and causing a ceiling collapse.
Move furniture, electronics, and valuables away from the affected area.
If you can safely access the attic, trace the leak to its source. Place a tarp or heavy plastic over the area from the inside, securing it with boards.
Do NOT get on the roof during a storm. Roof tarping from the outside should wait until conditions are safe or be handled by an emergency roofing crew.
Document everything for insurance.
Call a roofing contractor the next business day. Emergency tarping services are available 24/7 in most markets ($200-$500).

Prevention: Inspect your roof twice a year (spring and fall). Replace missing or damaged shingles promptly. Keep gutters clear to prevent ice dams. Seasonal Home Maintenance: Spring, Summer, Fall, Winter Checklists

Sewer Backup

Stop using all water in the house immediately. Do not flush toilets, run sinks, or use the washing machine.
Do not attempt to clean sewage yourself if it is more than a minor amount. Raw sewage contains harmful bacteria and requires proper protective equipment.
Call an emergency plumber or sewer specialist. They will use a camera to diagnose the blockage (tree roots, collapsed line, grease buildup) and clear or repair it.
For significant backups, call a water mitigation company to handle sanitization and drying. Insurance may cover sewer backup if you have the appropriate rider on your policy (check before you need it).

Prevention: Avoid flushing anything other than toilet paper. Schedule a sewer line camera inspection every 3-5 years, especially if you have mature trees near your sewer lateral. Consider a backflow prevention valve if your area is prone to municipal sewer overloads.

HVAC Failure in Extreme Weather

When your furnace dies during a polar vortex or your AC fails during a heat wave, comfort becomes a safety issue.

For heating failure: Close off unused rooms to concentrate warmth. Use portable electric space heaters (one per room, never near curtains or bedding). Layer clothing and blankets. Open blinds on sun-facing windows during the day.
For cooling failure: Close blinds to block solar heat. Use portable fans and window units. Stay hydrated. If indoor temperatures exceed 95 degrees F and you have vulnerable household members (elderly, infants, people with medical conditions), relocate to a cooled environment.
Call an HVAC contractor. Many offer emergency service with same-day response. After-hours service calls typically add $100-$200 to the base visit fee.
Common quick fixes: Check the thermostat batteries, make sure the breaker has not tripped, and verify the furnace filter is not completely clogged (a severely blocked filter can trigger a safety shutdown).

Prevention: Schedule professional HVAC maintenance twice a year (heating in fall, cooling in spring). Replace filters every 1-3 months. Seasonal Home Maintenance: Spring, Summer, Fall, Winter Checklists

Broken Window

If the window is shattered, wear heavy gloves and eye protection to remove loose glass shards.
Cover the opening with plywood, heavy cardboard, or heavy-duty plastic sheeting. Secure with screws (plywood) or strong tape (plastic). This keeps weather, insects, and intruders out.
If the window is cracked but intact, apply clear packing tape over the crack to prevent further spreading until it can be replaced.
Call a glass repair service or window company. Standard single-pane replacement is often same-day. Double-pane insulated glass units may need to be ordered (1-2 weeks).

Flooded Basement

Do NOT enter standing water if there is any possibility of contact with electrical outlets, appliances, or wiring. Go to your panel and kill the breaker for all basement circuits first.
If the water is deeper than a few inches, call a water mitigation company. They have commercial pumps and dehumidification equipment.
For minor flooding (less than an inch), use a wet-dry vacuum to remove water, then run dehumidifiers and fans continuously for 48-72 hours.
Remove wet carpeting, drywall (cut 12 inches above the waterline), and insulation. Mold can begin growing within 24-48 hours in damp conditions.
Document everything for your insurance claim before discarding damaged materials.

Prevention: Install a battery-backup sump pump. Grade the soil around your foundation so it slopes away from the house. Keep gutters and downspouts clear and extend downspouts at least 4 feet from the foundation. Seasonal Home Maintenance: Spring, Summer, Fall, Winter Checklists

Emergency Numbers Every Homeowner Should Have

Keep this list in your phone and posted in a visible location.

Contact	Number / How to Find
Fire / Police / Medical	911
Gas company emergency line	On your gas bill or utility website
Electric utility emergency line	On your electric bill or utility website
Water utility emergency line	On your water bill or utility website
Poison control	1-800-222-1222
Trusted plumber (24/7)	Research and save before you need it
Trusted electrician (24/7)	Research and save before you need it
Water mitigation company	Research and save before you need it
Insurance company claims line	On your policy documents or insurance card
Neighbor with a spare key	Arrange this in advance

When to Call 911 vs. a Contractor

Call 911 if:

There is a fire of any size
You smell gas
There is risk of structural collapse
Someone is injured
Flooding involves electrical hazard you cannot safely isolate

Call a contractor when:

The immediate danger has been addressed or eliminated
You need a repair but no one is in danger
The situation can wait hours (not minutes) for professional attention

When in doubt, call 911. Fire departments and paramedics would rather respond to a false alarm than arrive too late.

Insurance Claims for Home Emergencies

Contact your insurer within 24 hours. Most policies require prompt notification.
Document everything. Photos, video, receipts, and a written timeline of events.
Make temporary repairs to prevent further damage. Your policy requires you to mitigate damage; keep all receipts for reimbursement.
Do not make permanent repairs before the adjuster visits unless the insurer authorizes it.
Get your own estimate. Do not rely solely on the insurance company’s preferred contractor. An independent estimate from a contractor you trust gives you leverage. How to Get Multiple Quotes and Compare Contractors
Know your deductible. If the damage is close to your deductible amount, filing a claim may not be worth the potential premium increase.

Prevention: The Best Emergency Plan

Most home emergencies are preventable with regular maintenance. A structured seasonal approach catches small problems before they become urgent ones.

Inspect your roof, gutters, and downspouts every spring and fall.
Test your sump pump quarterly by pouring a bucket of water into the pit.
Service your HVAC twice a year.
Know where your shutoffs are (water main, gas valve, electrical panel) and make sure every adult in the household knows too.
Insulate pipes in unheated areas before winter.
Test smoke detectors, CO detectors, and fire extinguishers twice a year.

Seasonal Home Maintenance: Spring, Summer, Fall, Winter Checklists

Key Takeaways

The first five minutes matter most. Knowing where your water shutoff, gas valve, and electrical panel are located saves critical time during an emergency.
Gas leaks and electrical fires require evacuation first, repairs second. Never prioritize property over personal safety.
Document everything before you clean up. Photos and video are essential for insurance claims.
After-hours emergency rates are higher, but waiting can cost far more. A $300 emergency plumber call prevents $13,000 in water damage.
Prevention is cheaper than repair. Regular seasonal maintenance eliminates most emergency scenarios before they start.
