How to Winterize Your Home for -20°C to -30°C Tempeartures

Winter can be beautiful, but when temperatures drop to -20°C or lower, it’s no joke. Properly winterizing your home can save you money, prevent damage, and keep you cozy no matter how cold it gets. Here’s a friendly guide with practical tips to get your home winter-ready:

1. Seal Those Drafts

• Why: Drafts let in cold air and drive up your heating bills.

• How:

        • Use weatherstripping around windows and doors.

        • Install a door sweep at the bottom of exterior doors.

        • Apply caulking to seal gaps in window frames.

• Pro Tip: If you feel a chill near your front door, try holding a lit candle close to the edges. If the flame flickers, you’ve found a draft! Identifying and sealing all drafts can reduce heat loss and cut heating costs by up to 15%.

2. Insulate, Insulate, Insulate

• Why: Proper insulation keeps the warmth in and the cold out.

• How:

        • Check your attic—if the insulation is thin, add more.

        • Wrap pipes in unheated areas (like basements) with foam insulation to prevent freezing.

        • Use thermal curtains or blinds for added window insulation.

• Pro Tip: Focus on attic insulation—it’s where most heat escapes. Adding an extra layer can make a noticeable difference. Proper insulation ensures consistent indoor temperatures and lowers heating bills.

3. Prepare Your Heating System

• Why: A reliable furnace or heating system is your best friend in extreme cold.

• How:

        • Schedule a furnace tune-up before winter hits.

        • Replace or clean filters monthly.

        • Test your thermostat to ensure it’s working efficiently.

• Pro Tip: While upgrading to a programmable thermostat like Nest or Ecobee can help maintain ideal temperatures and save energy, regular maintenance extends the life of your heating system and ensures efficient performance, reducing unexpected breakdowns.

4. Prevent Frozen Pipes

• Why: Frozen pipes can burst, leading to costly water damage.

• How:

        • Keep cabinet doors under sinks open to allow warm air to circulate.

         • Let faucets drip slightly during extreme cold to prevent pressure buildup.

         • Shut off outdoor water supply and drain hoses.

• Pro Tip: If you’re travelling, set your thermostat to at least 15°C to prevent freezing while you're away and ask a neighbour to check your home. Preventing frozen pipes saves you from expensive repairs and the headache of water damage.

5. Protect Your Roof and Gutters

• Why: Snow and ice buildup can cause leaks or damage.

• How:

        • Clean gutters before the first snowfall to prevent ice dams.

        • Use a roof rake to remove excess snow after heavy storms.

        • Check for loose shingles and repair them.

• Pro Tip: Install gutter guards to reduce debris build up and make cleaning easier.  A well-maintained roof and gutter system prevent leaks, saving you from costly repairs in spring.

6. Create a Cozy Indoor Environment

• Why: A warm home is only as good as how comfortable you feel in it.

• How:

        • Use area rugs to keep floors warm.

        • Add extra blankets and throws on couches and beds.

        • Light candles or use a fireplace for added warmth and ambiance.

• Pro Tip: A weighted blanket not only keeps you warm but also helps you sleep better during long winter nights! Creating a cozy environment makes those cold winter nights something to look forward to!

7. Stock Up on Winter Essentials

• Why: Being prepared can save you from last-minute stress.

• How:

        • Keep salt or sand handy for icy driveways and walkways.

        • Stock up on pantry staples and bottled water for snowstorms.

         • Have a snow shovel and car emergency kit ready.

• Pro Tip: Make it a fun family activity to create a winter emergency kit together! Stocking up can save you from last minute trips to grocery store during a snowstorm only to find out the shelves are empty.

8. Humidify the Air

• Why: Cold, dry air can wreak havoc on your skin and respiratory system.

• How:

        • Use a humidifier to maintain indoor humidity around 30-50%.

        • Place bowls of water near heat sources for a natural alternative.

• Pro Tip: Monitor humidity levels using a hygrometer to avoid over-humidifying, which can lead to condensation on windows. A humidified home feels warmer, reduces static electricity, and protects your skin, hardwood floors and furniture. 

9. Test Your Smoke and Carbon Monoxide Detectors

• Why: Increased use of heating systems and fireplaces can raise the risk of fire or carbon monoxide leaks.

• How:

        • Replace batteries in detectors before winter starts.

         • Test them monthly to ensure they’re working.

• Pro Tip:  Carbon monoxide is odourless and deadly—invest in a high-quality detector for peace of mind. Regular checks protect your family from dangerous, unseen risks—don’t skip this step! 

10. Winterize Outdoor Areas

• Why: Protecting your outdoor spaces prevents damage and makes spring cleanup easier.

• How:

        • Store outdoor furniture and cover items that can’t be brought inside.

        • Drain and store garden hoses.

        • Use salt or sand to keep walkways and driveways safe from ice.

• Pro Tip: Invest in a durable snow shovel or a snowblower to handle heavy snowfalls easily. Properly maintaining outdoor areas ensures safety and reduces cleanup efforts when winter ends.

Winterizing your home doesn’t have to feel overwhelming. By following these steps, you’ll stay warm, safe, and stress-free even when temperatures plummet. Stay cozy this winter, and remember—preparation is the key to surviving those frigid -20°C and below days! Happy Winters!
