The first hard frost is weeks away in most of Canada, and the cheapest time to fix a draft is before the furnace starts running full time. None of the upgrades below need a contractor, most take less than an hour, and each one usually costs under $50 at Canadian stores.

We focused on fixes that matter in a Canadian winter: stopping drafts, protecting pipes, managing dry indoor air, and dealing with salt, snow and block heaters. Where a tip comes from Natural Resources Canada or Health Canada, we say so.

Why start with drafts

According to Natural Resources Canada, windows, doors and skylights can account for up to 35% of a home’s total heat loss, and sealing air leaks is the single most important energy upgrade to do first. The good news is that sealing leaks is also the cheapest work on this list.

The list at a glance

1. V-strip weatherstripping for doors and windows
2. A door sweep or door-bottom seal
3. A window insulation film kit
4. A fabric draft stopper
5. Foam gaskets for outlets and switches on outside walls
6. Paintable indoor caulk and a caulking gun
7. Foam pipe insulation
8. An outdoor faucet cover
9. An outdoor timer for your car’s block heater
10. A carbon monoxide alarm
11. A digital humidity monitor (hygrometer)
12. A small cool-mist humidifier
13. A boot tray and a salt-resistant entry mat
14. ENERGY STAR LED bulbs
15. A good snow brush and ice scraper

1. V-strip weatherstripping for doors and windows

Natural Resources Canada says a good-quality V-shaped vinyl strip is the easiest and most effective weatherstripping for a door frame, because it keeps sealing even as the door warps with the seasons. It works on the sides of hung windows too.

Tip: Hold a lit incense stick near the door edge on a windy day. If the smoke flickers, you have a leak worth sealing.

2. A door sweep or door-bottom seal

The gap under an exterior door is one of the biggest draft sources in most homes. A sweep screws or sticks to the bottom of the door and closes it. Pick one with slotted holes so you can adjust it as the door shifts.

Tip: Measure the door width before you buy. Most sweeps can be cut to length with a hacksaw.

3. A window insulation film kit

Natural Resources Canada says windows, doors and skylights can account for up to 35% of a home’s heat loss. Heat-shrink film kits add a layer of still air over the glass: you tape the film to the trim and tighten it with a hair dryer. It is the cheapest fix for old or single-pane windows.

Tip: The tape can lift paint when you remove it in spring. Test a small spot first.

4. A fabric draft stopper

For interior doors, basement doors and doors you can’t easily fit a sweep to, a weighted fabric stopper blocks the gap in seconds. No tools needed, which also makes it a good fix for renters.

Tip: Look for a double-sided type that slides onto the door, so it moves with it when you open and close it.

5. Foam gaskets for outlets and switches on outside walls

Electrical boxes on exterior walls are small holes in your insulation. Foam gaskets sit behind the cover plate and stop the cold air you can often feel on your hand. A pack does a whole house.

Tip: Turn off the breaker before you take off the cover plates.

6. Paintable indoor caulk and a caulking gun

Natural Resources Canada calls air leakage control the single most important upgrade to do first, and caulking is how most of it gets done. Run a bead where window and door trim meets the wall and along baseboards on outside walls.

Tip: Use caulk labelled for indoor use on the inside. Exterior caulk is for the outside.

7. Foam pipe insulation

Pipes in unheated spaces, like a garage wall, crawl space or near an exterior wall in the basement, are the ones that freeze and burst. Slit foam sleeves snap on without tools.

Tip: Start with any pipe that has frozen before and the line to the outdoor tap.

8. An outdoor faucet cover

After you shut off and drain the outdoor tap from inside, an insulated cover gives the fixture extra protection against a hard freeze.

Tip: Disconnect the garden hose first. A hose left attached traps water in the tap.

9. An outdoor timer for your car’s block heater

A block heater does not need to run all night. A heavy-duty outdoor timer switches it on a few hours before you leave, so the engine is warm and you are not paying to heat it while you sleep.

Tip: Buy one rated for outdoor use and for the wattage of your block heater.

10. A carbon monoxide alarm

Furnaces, fireplaces and attached garages all run harder in winter. Health Canada recommends at least one CO alarm near bedrooms, and preferably one on each floor. Plug-in models with battery backup are easy to add.

Tip: Check the date on the back of any alarm you already own. CO alarms have a limited life, often around 7 to 10 years.

11. A digital humidity monitor (hygrometer)

Canada.ca advises keeping indoor humidity around 30% in winter to limit mould. Too dry, and you get dry skin and static; too humid, and you get condensation on windows. A small monitor tells you which one you have before you buy anything else.

Tip: Put it in a bedroom, away from the kitchen and bathroom, for a fair reading.

12. A small cool-mist humidifier

If your monitor reads well below 30%, a small humidifier in the bedroom helps with dry skin and sinuses. Health Canada advises emptying and cleaning cool-mist humidifiers often so germs do not build up in the tank.

Tip: Buy only if you need it. Too much humidity causes condensation and mould.

13. A boot tray and a salt-resistant entry mat

Road salt and slush wreck hardwood and baseboards. A raised-edge tray at each door keeps melting snow off the floor, and a rubber-backed mat catches grit before it spreads through the house.

Tip: Put a tray at every door you use in winter, including the one from the garage.

14. ENERGY STAR LED bulbs

Winter means the lights are on for more hours a day. Swapping the bulbs you use most for LEDs cuts that part of your bill, and they last for years.

Tip: Pick 2700K (warm white) for living spaces so they match the light of older bulbs.

15. A good snow brush and ice scraper

A long-handled brush with a pivoting head makes clearing an SUV or truck roof far easier, and a solid scraper saves your wiper blades from doing the work.

Tip: Keep a second scraper in the car and one by the door for the first surprise frost.

Do it all in one Saturday

1. Walk the house on a windy day with an incense stick and mark every draft with painter’s tape.
2. Weatherstrip and fit sweeps on exterior doors first. They are usually the biggest leaks.
3. Caulk trim and add outlet gaskets on outside walls.
4. Put film on the draftiest windows, especially older single-pane ones.
5. Shut off and drain the outdoor tap, fit the cover, and insulate exposed pipes.
6. Test or replace your CO alarms, and check humidity with a monitor before buying a humidifier.
7. Set up boot trays, the block heater timer and the car scraper before the first snow.

Frequently asked questions

Is window film worth it on newer windows?

Usually not. Film helps most on old, drafty or single-pane windows. On modern double-glazed windows, check the weatherstripping and caulk first.

What humidity should my home be in winter?

Canada.ca recommends around 30% in winter to limit mould. If your windows run with condensation, humidity is too high, not too low.

Are there government rebates for these?

Small DIY items like these usually are not covered, but bigger upgrades such as insulation, windows and heat pumps often are. Check your province and your utility’s current programs before you plan larger work.
