(BPT) – With winter comes the holiday season, a time that’s supposed to be associated with comfort and joy. How joyful can it be if pests invade your house or if your home is cold and drafty?

Stay warm all winter long by addressing air leaks from gaps and cracks that make your home feel uncomfortable.

“Drafts and heat loss are common problems in the winter, and they affect homes of every age, size and construction,” says Gary Parsons, fellow at The Dow Chemical Company. “Those factors can seriously affect your home’s energy efficiency and how comfortable it feels. Fortunately, it’s not difficult to deal with issues like air leaks and insulation, and doing so can significantly improve your home’s function and livability.”

Parsons suggests the following steps to help ensure a draft-free, pest-free and comfy home this winter season!

warm house prep tips

Seal cracks and gaps

They’re everywhere!

Gaps and cracks throughout the home allow hot air to escape and cold air and pests to enter. Energy Star estimates that homes can have a half mile or more of cracks around doors, windows and sill plates alone!

Those aren’t the only places in a home where gaps can exist. Air duct joints, points where piping enters a home, and anywhere wood meets concrete (such as around the foundation) are locations where cracks and gaps can occur.

Sealing cracks can help prevent air leakage, improve a home’s overall energy efficiency and block out pests and insects. In fact, homeowners can save an average of 15% on heating and cooling by air sealing their homes and adding insulation, according to Energy Star.

How to fix it!

Even do-it-yourself novices can easily and quickly seal cracks and gaps in their homes.

Check out products like GREAT STUFF(R) Gaps & Cracks and GREAT STUFF(R) Pestblock Insulating Foam Sealants.

They are specially formulated to seal gaps and cracks, blocking out air, moisture and even pests. The ready-to-use insulating foam sealants can fill gaps up to 1 inch. When using the product, be sure to follow safety guidelines, including covering all skin, using gloves and safety goggles, and keeping the work area well ventilated.

Check insulation

Insulation is like a blanket that your home wears to help keep everyone inside warm and cozy. If your home doesn’t have the right amount or type of insulation for your climate, it can lose heat, energy efficiency and comfort. About 90 percent of existing homes don’t have enough insulation, according to the North American Insulation Manufacturers Association.

Follow Energy Star’s guidelines for more information on how to check your insulation to see if your home could benefit from adding more.

Take care of the HVAC system

If your hvac systems aren’t working as well as they could, you’re sacrificing comfort and your energy bills!

Make sure to check the cooling system in the spring and the heating system in the fall to ensure they are operating efficiently.

Have the ducts inspected and seal any leaks. Be sure to change air filters regularly, per the system manufacturer’s recommendation for filter type and frequency. According to the U.S. Department of Energy, dirty air filters restrict airflow, making HVAC systems work harder and consume more energy to heat your home.

Don’t overlook little things

Things as simple as a forgotten window left cracked in summer months or neglecting to close the flue in your wood-burning fireplace can all affect the amount of heat and comfort that escape your home in the winter.

Before the weather turns very cold, make a sweep through your home and check for these minor but important points:


  • Are all your windows closed? If you’ve recently sealed around windows, you probably opened them for ventilation. Double check to be sure you remembered to close them.


  • Is yours properly programmed to optimize energy use by adjusting the temperature when you’re out of the house? Proper use of a programmable thermostat can cut energy bills by nearly $200 per year, according to Energy Star.

Ceiling fans

  • You can use ceiling fans to supplement your furnace during the winter. Just remember to reverse the air flow!
  • Most ceiling fans have a switch that allows you to reverse the direction of the fan blades to spin clockwise. This pushes warm air down from the ceiling during winter.
