Carbon Monoxide Can Seep From Your Garage Into Your House: What To Do About It

Posted on: February 20th, 2013 by

Although attached garages are extremely convenient, it is important for homeowners to be aware that they can also become a potential threat to your family’s safety. Carbon monoxide (CO) from your vehicle and other sources can find its way into your home when your garage is not properly ventilated. When you are aware of problem areas and take measures to protect your house from carbon monoxide, you can rest assured that your family will be safe.

How can carbon monoxide enter my house?

If you are like many homeowners, it can be tempting to run your car in your garage in order to “warm it up.” When your garage is not ventilated, however, your vehicle’s emissions and a lack of oxygen produce carbon monoxide due to the incomplete combustion process. In fact, it only takes two minutes for the fumes from your car to build up to lethal concentrations in your garage. Even just momentarily starting your car in the garage can produce CO that becomes trapped inside when you close the overhead door. If the sealant around the doorway to your house is inadequate, or if there are porous holes and cracks in the wall between your garage and home, the gas will find its way inside and pose a serious health risk.

How can I prevent it?

There are measures you can take to prevent carbon monoxide from entering your home. One of the simplest and most effective measures is to work with your HVAC contractor to properly seal your door and any areas of your wall that have compromised integrity. Your contractor may also recommend an exhaust vent for your garage. Be sure to equip your home with a carbon monoxide monitor which will provide readouts of the CO levels in your home at any given time. In this way, you will know right away if CO is entering your house after starting your car.
