How to Insulate Your Home

Brrr! Cold weather is on the way. For some northern and Midwestern states, the frigid temperatures have already arrived. The good news is there are several repairs, chores and upgrades homeowners can complete to improve insulation and improve energy efficiency during colder months. And, it’s not late to get them done!

The repairs and home improvement opportunities below will help to create a comfortable and cozier living space for your family and you to enjoy when the weather outside is too freezing and frightful.



The first area of your home to insulate before the winter weather arrives is the attic. The average homeowner spends almost no time in their attic. I would recommend at least one trip up there each year to inspect the condition of the insulation on the floor. Be aware of areas of the attic floor that need more insulation installed. Be sure to review the roof above too. Look out for gaps and crack where cold win and air could come through. Attic insulation can be purchased from a local hardware store.


I recommend a trip to a local hardware store or retailer to purchase plastic window sealant. The cost is very low and will ultimately save you money in heating and electric bills during the winter. The project requires about 1-2 hours of time depending on the number of windows in your home. Place the plastic across each window and then seal it to the window frame with tape. One or two rolls of the sealant should be enough to complete the job.


The best type of flooring for cold weather is carpet. I would recommend carpet for living rooms and bedrooms in homes in cold weather areas of the United States. Carpet is warm and provides insulation on the ground. For homes with hardwood or laminate flooring, consider placing large area rugs in order to insulate high-traffic areas throughout the house.


Don’t forget to replace the furnace filter in the furnace in your home before winter. A fresh filter is much more efficient than a dirty one and will help reduce energy and heating costs in your home during cold months. This is an easy job. A quality furnace filter typically costs around $10-20 at a local hardware store and can be installed in 1-2 minutes or less. Refer to for tips on replacing a furnace filter.


You can add heat in a room with the strategic placement of space heaters. You can purchase a quality space heater for around $60-100 from a hardware store. Be careful to remember to turn off and unplug space heaters before leaving your home or going to bed for the night. Depending on how cold the weather is outside, you might consider just running a space heater and curling up beneath a blanket instead of turning up the heat in your home as it will be much cheaper.

I hope the tips above are helpful for keeping your home warm this upcoming winter. A cold home is not comfortable or inviting for friends and holiday guests. Most of the projects above can be completed in a weekend and will be beneficial in preventing cold air from the outdoors from entering inside your home.
