'Stop annoying chills' and save money – draft proofing your living room will slash energy bills by a third

Draft proofing a living room is essential for improving comfort, reducing energy bills, and creating a cozy space, especially during colder months. Families often spend the most time in living rooms, making them a priority for effectively sealing drafts.

In this article, I'll reveal to you exactly how and why you should draft proof your living room, based on my many years of experience as a heating, ventilation and air conditioning (HVAC) technician. I'll also tell you the common mistakes to avoid, plus recommend some top products us experts love.

Knowing how to run and clean your HVAC system, as well as how to draft proof your living room, is key to managing your home climate efficiently.

Why you should draft proof your living room

We know that families typically spend a lot of time in the living room – some estimates say about 40% of indoor relaxation hours are spent there. I know better than most as founder of Air Conditioner Lab that a drafty living room can make it much less inviting, and lead to higher energy bills because your heating and cooling system has to work harder.

The good news is that just a few simple draft reduction measures can cut heating and cooling costs by 10% to 30%, depending on how leaky the room is. Reducing these drafts helps keep the temperature more consistent indoors and stops that annoying chill around the ankles on winter evenings. Check out the 'goldilocks' temperature for your thermostat.

Additionally, draft-proofing prevents external pollutants like dust and allergens from entering your home.

How to draft proof a living room

When I start draft proofing, I check the windows and doors. If you're not so confident, try using a candle. A flickering flame reveals a draft.

I add weatherstripping around window frames and door edges to block cold or hot air from getting in. This M-D White Vinyl/Foam Door Weatherstrip from Lowe's is easy to install, but my top tip is Frost King M13WH V-Shape Weatherstrip, available from Walmart. I like this product because it's flexible, easy to measure and cut, and sticks well. It helps close those window gaps without much hassle and can handle regular window opening and closing without wearing out too fast.

I sometimes apply insulation film to windows and use a draft stopper at door thresholds to seal any gaps. This Duck Brand Rolled Insulation Film Window Kit from Walmart is my preferred choice. This transparent film is easy to apply and works well for holding in warmth during winter months. While triple pane windows are worth the investment, they're not always a viable option, so I like that this solution is affordable, doesn't block your view, and can help reduce energy loss through old or single-pane windows.

Next, I inspect electrical outlets and light switches on external walls – small foam gaskets behind the plates can seal minor leaks. If there's a fireplace, I ensure the damper is properly sealed when not used. Lastly, I fill any cracks around skirting boards or where pipes and wires enter the room with caulk for extra sealing. This multi-use GE Silicone All Purpose Caulk from Lowe's is great for sealing around windows, doors and electrical outlets.

Adding area rugs or using underlay insulation beneath carpets can also help reduce drafts through flooring. Check out Homes & Gardens' guide to the 15 best rugs to shop right now.

What to avoid when draft proofing a living room

When it comes to common mistakes, the first thing you want to avoid is a quick patch job that won't last, such as low-quality tapes that start peeling after a few weeks.

I also pay attention to selecting the right material for each area. For example, some weatherstrips work better on doors than windows, and not all sealants hold up well in humid conditions. Check out a good dehumidifier below, plus these six things you need to know before buying a dehumidifier.

Another thing I'm careful about is maintaining proper ventilation – it's never good to seal off necessary airflow or ignore proper humidity control. Check out Homes & Gardens' brilliant guide to whether you should close vents in unused rooms, in which I feature.

Can I draft proof my living room on my own?

Yes. Many steps are easy, such as adding a draft stopper or applying weatherstrips. If you still feel cold spots after your best efforts, or if you encounter structural issues, consider a professional's help.

Are thermal curtains worth it for draft proofing a living room?

How often should I check my draft proofing?

It's a good idea to inspect your living room for drafts at least once a year. Over time, caulking and weatherstripping can wear out and need replacement.
