You’re sitting on your couch in the dead of winter, the heat is on, but you can still feel cold air blowing across the room. You notice your energy bills climbing higher every month. You try turning up the thermostat, but it doesn’t seem to help. Where is all that cold air coming from?
Drafty windows and doors are one of the biggest energy wasters in Indiana homes. They make your heating system work overtime, drive up your bills, and leave certain rooms uncomfortably cold no matter how high you set the thermostat.
At Hoel Roofing & Remodeling, we’ve helped hundreds of homeowners in Rushville, Columbus, and surrounding Indiana communities solve drafty window and door problems over the past eight years. We know exactly where cold air sneaks in and how to stop it, often with simple fixes you can do yourself.
In this article, we’ll explain in plain language why cold air comes through windows and doors, how to find the leaks in your home, and the most effective solutions from quick DIY fixes to permanent upgrades.
By the end, you’ll know exactly how to make your home warmer and cut your heating bills this winter, without needing any special tools or knowledge.
Cold air doesn’t magically appear inside your home. It sneaks in through specific problem areas. Understanding where and why helps you fix it effectively.
Small openings between the window frame and the wall, or between the door and the door frame, can let more air into your home. This happens because:
If the foam, rubber, or vinyl strips attached to door frames and window sashes that create a seal when closed start to fail, you may get more air leaks than usual. They typically fail because:
Windows with just one layer of glass instead of two (double-pane) or three (triple-pane). Using single-pane windows may sound harmless, but they can be problematic because:
The caulk or sealant around the outside of your window or door frame, where it meets your house siding, could be leaking and potentially be causing air leaks. Some likely reasons the caulk or sealant leaks are:
The space between the bottom of your door and the threshold (the piece on the floor) may also be responsible for air leaks. Under-door gaps are typically because:
Even the smallest of gaps under doors adds up.
Before you can fix drafts, you need to find them. Here’s how to locate all the leaks in your home:
On a cold, windy day, slowly move your hand around the edges of windows and doors. Feel for moving air.
Where to check:
You should feel cold air movement, temperature differences, or a breeze on your hand.
Light a candle or incense stick and slowly move it around window and door edges. Watch the flame or smoke.
What to look for:
Important Tip: Keep candles away from curtains and don’t leave them unattended.
A visual inspection can be helpful to find the source of air leaks. Here’s what to look for:
Place your hand flat against the window glass on a cold day.
Check for:
Make a list of every problem area you find. This becomes your action plan.
Most draft problems can be fixed with simple, inexpensive solutions from your local hardware store:
If DIY fixes aren’t enough, these more permanent solutions make a bigger difference:
Why can I feel cold air even when my windows and doors are closed?
Cold air usually comes through small gaps around frames, worn weather stripping, failed caulk, or under-door gaps, and not through the glass itself. Even tiny openings can let in a surprising amount of cold air.
Is it normal to feel cold air near windows in winter?
A slight temperature difference near windows is normal, especially with older or single-pane windows. However, feeling an actual breeze or cold airflow means there’s an air leak that should be sealed.
What’s the fastest DIY fix for cold air coming through doors?
Installing or replacing a door sweep and weather stripping is usually the quickest and most effective fix. These materials are inexpensive and can often be installed in under an hour.
Do plastic window insulation kits actually work?
Yes, for short-term solutions. Plastic window film can significantly reduce drafts and heat loss during winter, but it’s not a permanent fix and needs to be removed each spring.
How long does weather stripping last?
Basic foam weather stripping typically lasts 3–5 years. Higher-quality materials like reinforced silicone or spring bronze can last 10–15 years when installed correctly.
Sometimes fixing old windows and doors is like putting a Band-Aid on a bigger problem. Here’s when replacement makes more sense:
