Tips on how to keep basement warm this winter

It is important that you insulate your basement in order to minimize heat loss. Here are 6 ways that you can increase the insulation in your basement, and also keep the warmth inside.

Find Cold Spots

Finding cold spots is the first step in reducing heat losses in your basement. A thermal camera can be used to scan the entire room, floor to ceiling. If you find areas in your basement that are significantly colder than others, you can begin to seal or add insulation. 

Additional insulation is an option to keep warm air inside and cold air out

The key to your home’s comfort and energy efficiency is a properly insulated basement. While the Earth itself can be great natural insulation, it is not enough to keep your basement warm. There are many types of insulation available for your basement walls.

If your basement is not finished and has stone or concrete walls visible, framing the basement with insulation and drywall will help to retain heat better. For concrete walls, fiberglass insulation is preferred. You may be able to add spray foam insulation to basement walls if you have them. The rim joists and headers in your flooring and roofing systems are what separate your basement from the main floor. They are typically positioned against the outer walls of your house and can be exposed to the outdoors. With no insulation, they allow for the warm air rises from the basement and the cold air coming in from the outside.  Additional spray foam insulation can be added as a sealant.

It is important to remove all trim around basement windows. To add insulation, you could also install a subfloor over the sleeper strip. Your house’s air ducts are responsible to channel air around it. These ducts should be replaced with well-insulated or at the very least, wrapped in no gap insulation.

Seal cracks and leaks in foundations, floors, or walls

Heat loss from your basement can be caused by air leaks around the windows, doors, rim joists, seams, and joints between the floors, walls, and ceiling. Seal any cracks with the correct sealant for your material. Foam sealants are more flexible than silicone and can also be painted. Silicone sealants, on the other hand, are more flexible and can withstand shrinking and expanding wood around your windows. Your existing sealant will eventually wear out so be sure to renew your sealant with your doors, windows, and other edges every five years.

Make basement’s existing windows or walkout doors to be more energy-efficient

Glass windows can lose a lot of heat, especially if they are single-glazed. Double-glazing windows will provide better insulation. To improve insulation, this technique uses two pieces of parallel glass that have air or gas in between them. Double-glazed windows can be fitted with a reflective tint in one direction to increase heat retention.

Add thick floor rugs or carpets

Basements often have tiled or cement floors that are very cold. They also cause heat loss. To reduce heat loss, make sure you cover the entire floor if there are no flooding or moisture problems. You don’t have to buy wall-to-wall carpeting if you are looking for cheap ways to heat your room. However, placing a throw rug on areas that are frequently used will help keep your feet warm. For the best insulation, add floor rugs that has thicker piles and a higher stitch count.

Use heavy curtains or cellular shades

Heating a basement room can be as simple as layering thick curtains on your windows. Cellular shades can be a better option than heavy curtains. They are more effective at reducing heat loss by up to 80%, according to Cellular shades are honeycomb-shaped with air pockets for insulation.

Heating Options to Make your Basement Warmer

Once you have insulated your basement and reduced heat loss, it is time to start heating your basement. This will make your basement more cost-effective and efficient. These heat-adding options will add warmth to your basement at different price points.

Install additional heat vents

As you consider the convenience and future savings, tapping into your home’s existing ductwork to expand your central air system into the basement could be a smart move. Although adding heat vents to your home can be more expensive upfront than purchasing a space heater it will have a lower impact on your monthly electricity bills over the long term. To determine if it is possible to heat your basement, as well as how to install it, consult an HVAC professional.

Install a heated floor

If you don’t mind paying a little more for installation and your electricity bill, a basement floor heating system can be a great choice. There are two options for floor heating: electric radiant heat is where an electric wire is placed beneath the basement floor to supply low-level heat to concrete, stone, or tiled flooring. Hydronic heat is where hot water circulates in pipes underneath the floor to heat it. While both are expensive, they offer great benefits. The heat will rise naturally and fill your basement.

Install a basement heating system

There are two other options for basement heating that homeowners love: electric baseboard heaters or wood pellet stove fireplaces. Baseboard heaters, which are low-to-the-ground convection space heaters, are ideal for heating single rooms. Baseboard heaters are limited in that you cannot place your couch or any other heavy furniture against the heater’s wall. Fireplace stoves that burn wood or pellets can be used to heat larger basements, but they require ventilation through chimneys. This installation is expensive, but the benefits will last for many years.

Use a Space Heater

You can heat your basement with a space heater without spending a lot of money on electricity. Space heaters are easy to install and can be used by anyone. There are two things you should avoid with space heaters. Use it in small rooms or for short periods. Also, pay attention to the manufacturer’s instructions on how to unplug it after you have left the room to avoid fire dangers.


It is smart to move some of your daily activities into basements, especially if you want to maximize space. If you plan to use it as a living space, it is worth researching how to keep your basement warm throughout the entire winter.
