Experts advise British Columbians to prepare their homes for winter

As colder weather from strong winds and heavy snow to freezing rain rolls intoBritish Columbia, it's important to winterize homes to be better prepared for the weather, experts say.

Environment Canada has issued extreme cold warnings for most of the province on Christmas Day, with much of Metro Vancouver waking up to snowfall and a "White Christmas".

Temperatures are expected to go down to 30 C in Prince George, with extreme wind chill values making it feel like 50 C in some locations.

The forecaster is warning the province's cold snap is set to last a while, and is telling people to be mindful of pets and keep emergency supplies on hand.

Here is some advice from expertson how best to prepare your home for extended periods of freezing temperatures.

Prepare the basics

For starters, have emergency supplies ready bychargingup devices,says Nicole Kimmitt, the risk and emergency manager with the City of Coquitlam.

You should also have flashlights and extra batteries handy in case there is a power outage.

To prepare for severe weather, people should prepare supplies lasting at least two to seven days, according to Kimmitt.

"Making sure things like prescriptions are refilled with at least aweek's supply, so that you're not having to venture out into the terrible conditions," she said.

Tips for the exterior

Outside yourhome, disconnect any garden hoses from the hose bibs faucets outsideyour house that the hoses attachto.

According to Paul Friesen, a certified home inspector and owner of I Find It Inspections in Vancouver, B.C., any water still inside the hose will freeze in frigid temperatures. As the water expands, it can push backwards through the valve, causing the water line to freeze and pipes to burst.

Friesen says you should also ensure gutters anddownspouts are clean of debris like leaves and working properly to prevent water damage.

"Water will back up next to the house [during periods of snowfall and rain]," he explains.

"It has a high risk of coming through foundation cracks or through any types of holes in the siding and that could lead to wet basement issues, flooded basements, or wet crawl spaces," he explains.

And it's important to make sure there is not a lot of moss build up on the shingles of your roof.

"Not cleaningthe moss off your roof leads to the moss freezing and expanding which allows the shingles to become loose," saidFriesen.

It's also essential to assess surrounding trees and remove branches that could fall on your home or power lines during strong winds, adds Kimmitt.

Inside the home

To keep the cold air out and heat from escaping, check if weatherstripping around your doors needs to be replaced.

Every time you open and close a door, there's a little strip of plastic or nylon or foam around the edge of the door frame, explains Friesen. When you shut the door, the strip prevents the wind from coming in and out.

One way to check your door's weather stripping isby turning off the lights. If any light from outside is still visible around the door, the weather stripping needs to be changed, according to Friesen.

It's also important to check if your furnace filter needs to be replaced so heating can be efficient.The furnace filter collects dust from inside the house, preventing it from going through the furnace.

Friesen says dust build-up makes the furnace work harder, and can lead to premature furnace failure.

"You just take it out, you throw it away ... you should do that every three months, just as a good rule of thumb," he said.

Other steps to prepare for weather emergenciesinclude buying generatorsor other backup heat sources.

If possible, purchase heat sources that are not propane burnersand don't run on electricity in case the power goes out, Kimmitt says.

And if you are using your fireplace, make sure that your smoke alarms and carbon monoxide detectors are up-to-date and working, according to Friesen.

"Light a little match and blow it out right in front of your smoke alarm and let the smoke alarm go off," he advises.

Prepare your vehicle

And if you are heading away from your home, it's also important to have a winter survival kit in your vehicle, says Kimmitt.

This kit should include items like a 'grab-and-go bag' with water, non-perishable food, and first aid supplies. The province says you should also include winter toolslike a windshield scraper, snow brush, a spare wheel, extra clothing and footwear.

For more snowfall, also purchase the essentials like a snow shovel, salt or sand to prevent ice buildup on driveways, saysKimmitt.
