Why Does my House Smell like Gasoline

Why does my house smell like gasoline. If your home smells like gasoline, you may be breathing in fumes from gas-powered tools. Gasoline has a very distinct odour that can linger for days or weeks if not resolved quickly.

If the smell is noticeable indoors, it’s time to take action and find out what is causing it. You may wonder about why does my house smell like gasoline.

The following are some tips on how to identify the source of the smell and make sure your home is safe for living.

Gasoline has an unmistakable scent that can cling to everything in its path. This includes carpets, furniture, clothing, hair – anything exposed to gasoline will carry this aroma with them into your home.

Gasoline also contains volatile organic compounds (VOCs), which contribute even more odours when interacting with other chemicals in your home.

Gasoline smells can appear when you use gasoline-powered tools such as leaf blowers, string trimmers and chainsaws in or around the house. A gas leak from a car, lawnmower or snow blower can also cause lingering odours indoors.

Depending on location in your house, gasoline smells may originate in one room or multiple rooms at different concentrations. This means there may be more than one source for gasoline odours.

So it will take time to try and pinpoint which areas need immediate attention first.

Check Around All Appliances

Gasoline odours could mean an oil burner issue with your furnace, wood-burning stove or even water heater. This could mean a gas leak, and it needs attention right away if you want to avoid dangerous consequences.

Check Laundry Rooms

If your washing machine has been acting up lately and making strange noises, the source of the gasoline smell may be due to oil seeping into your laundry water.

Sometimes it can be hard to pinpoint where oil smells like this are coming from, but other signs such as black stains on clothes or residue on laundry tubs may indicate an oil problem.

Check Around Garbage Cans

A garbage disposal issue might cause gasoline odours if there is a blockage in the line. Ensure that this appliance is not leaking or broken by checking underneath sinks for any sign of wetness.

Another possible source of gasoline odours near your garbage can could be the collection of trash outside. If there is no lid on your trash can, gasoline vapours may be leaking in from outside and making their way inside your home.

Check Kitchen Appliances

Do you notice gasoline smells around your oven or stove? There could be a problem with your gas line, which has caused oil to leak and is now coming into contact with the hot burners and oven.

Check Around Dryer Vents

Make sure there are no holes or tears in the vent hose that connects your dryer to the outside of your home. If you notice that the hose has become detached, gasoline odours may be entering your home because there is a possible oil leak outside.

Check Around the Dishwasher

If you notice gasoline odours in your kitchen and they only linger when the dishwasher runs, there could be a problem with the appliance itself.

This is another case where it might also cause oil to drip into the water and cause similar wetness and stains.

Check Around Furnaces or Boilers

If you have gas heat or an oil-fired water heater that uses vents, then take a good look at these appliances for any sign of damage or leaks. Check underneath nearby sinks for standing water where there shouldn’t be any. Also, check outside nearby garages for gas can vapours escaping inside these are possible sources for this dangerous leak.

Check Basements

check the basement

Some people store gasoline fumes in their basements instead of their garages for lawn mowers, weed eaters or other gas-powered equipment.

If you store gasoline fumes in this area of your house, it’s wise to check inside for standing water and oil stains to ensure no indoor sources of gas leaks.

Check Gardens

Petroleum issues can be caused by gardening if you use garden chemicals or fertilizers that contain gasoline-like solvents like benzene.

Make sure not to store these hazardous substances near your home’s foundation. Check outside near basement walls, doors or windows for any sign that these chemicals might have spilled during application or storage.

Check Around Pools

Some problems could come from petroleum products being released into the air from pool chemicals if you have an above-ground pool.

Check all of your pool chemicals to make sure they have not gone wrong or been mislabeled so you can try and determine which chemical is causing the odours.

Check Water Heaters

Both electric and gas-powered water heaters can cause problems with petroleum issues if there are any leaks in the pipes, valves or electrical wiring.

Gas issues could also come from a pilot light that has gone out in a faulty unit caused by a dirty thermocouple or broken thermopile; in some cases.

Check Winterizing Equipment

If you use gasoline-powered lawnmowers, weed eaters, snow blowers etc., then check these pieces of equipment for leaks after each use.

Petroleum vapours will not only smell terrible and make you sick, but they could also cause an explosion if the fumes contact any electrical equipment.

In addition to checking outside your house for sources of these common petroleum leaks, take a look at some other possible causes of gasoline smells indoors:

Check Storage Spaces

Any storage space under your home’s deck or porch could be a source of gasoline odours entering your home from underneath, where this storage holds gas cans or gas-powered tools.

Look around any crawl spaces or places that might have been enclosed while new construction on your home where vapours can get trapped and enter inside.

Check Air Conditioners

The coils in some window units could accumulate dust and become a source of odours that enter inside from the outside. Check air conditioner coils, outdoor exhaust fans and any other small area where dirt can accumulate.

Check Under the Sink in Your Laundry Room

If you see patches in your laundry room, then check behind it for wetness or smell anything unusual when doing laundry in your home with these possible sources of gasoline emitting harmful vapours inside.

Check Your Building’s Ventilation System

If you are in a condo, apartment complex, etc., check with your landlord about this possible source of gasoline odours coming inside.

The ventilation system can pull exhaust air from gas-fired appliances like furnaces where hazardous substances escape poorly installed or designed.

Necessary Measures to Get Rid of Gasoline Smell Indoor

  • If there is a slight smell when you turn on certain appliances, don’t assume it means there’s something seriously wrong with these systems. Cleaning them should help get rid of the smell.
  • Unfortunately, some odours can linger, such as gasoline ones, so professionals should look at long-term problems. Turn off anything using natural gas
  • Natural gas appliances that are not in use should have the pilot light turned off to prevent fumes from entering your home.
  • See chimneys for possible damage every year. A crack or hole in a masonry fireplace flue can emit harmful carbon monoxide into your home.
  • Use only fuel-burning appliances adequately installed by professionals to heat your home.
  • Do not attempt to burn anything other than what you are told is safe. Do not attempt to test, troubleshoot, or make repairs on any heating appliance yourself unless manufacturers approve it for self-maintenance.
  • Operate kitchen and bathroom exhaust fans while cooking or taking hot showers.
  • If there’s something wrong with ventilation systems themselves, these fans can help remove some of the fumes from inside your home if they’re connected to a central system.
