What Causes Heat Loss in a House?

Does it seem as if you just can't seem to keep your house warm enough? If your furnace seems to be running constantly and you're still wearing layers of clothing and snuggling up under blankets to keep warm, there could be something causing heat loss in your home. Here are some different ways that your home can lose heat:

Air Gaps

Windows and doors are the main areas where you could have gaps that cause your home to lose warm air while letting cold air get inside. Caulking older windows can help, as well as using weatherstripping around doors. In extreme cases, you can cover windows with plastic until you are able to repair an air gap.


There are different types of insulation, each with its own quality level and lifespan. Over time, some insulation can deteriorate or become damaged, leaving the interior of your home exposed to the elements. A lack of adequate insulation will let cold air enter your home through the walls, floors, and ceilings.


While some homes might not have basements, there are some that still do — and it’s important to take care of them. Basement walls are typically constructed with concrete blocks, which are very poor insulators. If you have a basement, having the ceiling insulated will stop a lot of heat from escaping the main part of your home. You could even finish the walls, adding a good layer of high-quality insulation to stop further heat loss.


Attics are another area where heat can be lost in your home. Not only do you want to make sure that there is a sufficient amount of insulation in your attic, but you also need to be looking at any vents or windows as well. Look at both the structural integrity and whether or not any critters are able to get inside.
