Winterizing Your House - What Should You Prioritize?

As the crisp fall air begins to settle in, it’s never too early to start preparing for wintertime. If the trees in your neck of the woods have already started shedding their leaves, then the time has come for you to start winter-proofing your house. 

Are you hoping to enjoy a hassle-free winter and skip over any unforeseen circumstances due to bone-chilling temperatures? In that case, a thorough interior and exterior home inspection is recommended to uncover any potential problems.

Besides sparing you any last-minute worries, winterization preparations allow you to achieve significant energy savings while optimizing your comfort.

How to Winter Proof Your House in Canada—7 Tips & Steps for Winterizing

1- How to winterize your windows and doors

Air and water leaks are more common during winter, especially in older houses. A thorough door and window edge inspection will allow you to ascertain whether your home is subject to this sort of problem. Make sure these openings are sealed shut in every room of your house. Otherwise, your home will, without a doubt, experience significant heat loss, which will have a dramatic repercussion on your electricity bill.

Caulking around your windows and doors is, bar none, the best option to protect your home from cold air leaks. If the sealant bead is particularly dry or fading, then it’s time to strip it and re-caulk. Using a caulking gun, you can use a removable sealant on window and door frames.

2- Install window and door weather stripping

Before winter rears its ugly nose, you’ll soon notice that home improvement and hardware store shelves are overflowing with dozens of window and door sealants. Weather strippers keep the warm air in, preventing the cold air from seeping into your home. In doing so, you’re ensuring your comfort and you’ll automatically cut back on your energy usage.

This product is a clear plastic film that’s stretched over windows. Such a protective film comes with double-sided tape, allowing you to stick the film to the window frame. You’ll need to use a hair dryer to ensure the film adheres to the glazing properly.

In a house, it’s not uncommon to feel a cold draft sweep in from the bottom of doors. To fix such an issue, installing door sweeps is recommended, especially for your front door. There are several types of door sweeps retailed:

• Adhesive or not

• Screw-on

• Slide-on

• Staple-on

Product selection hinges on your needs and the type of door on which you’re looking to use it.

3- Remove your screens

Whether your screens are installed on the inside or outside face of your windows, removing them for winter is highly recommended. Since insects aren’t as present during that time of year, and you’re less likely to open your windows compared to summertime, why keep them?

By removing your screens, daylight will filter inside your home more easily and the sun’s rays will readily heat parts of your dwelling from outside. Doing so extends the screens’ lifetime and prevents weather-related damage. Before storing your screens, clean them thoroughly with soapy water and a damp rag. Wipe them dry and then store them in a safe area all winter long.

4) Home interior winterization

There’s a lot to look over when winterizing a home inside out, such as cleaning space or baseboard heaters to prevent foul odours and spreading dust when powered on.

Little did you know, but air also seeps in through your electrical outlets. To fix this sort of issue, you can easily purchase dedicated accessories at a hardware store to fit your outlets during winter. There are little foam plugs sold just for that. They’re placed inside every outlet to prevent cold air drafts. You can also use safety covers for outlets you barely or don’t use at all. 

Is a room in your house equipped with a portable window air conditioner? Might be best to remove it and board up the window accordingly. If you wish to leave it where it sits, make sure the part sitting outside is covered with a cover, ensuring it’s insulated all around.

Besides, if you feel your house is becoming humid as the cold front sets it, it’s best to invest in a dehumidifier instead. Retailed for $180–$420, this sort of air conditioning electrical device is designed to lower humidity levels and fix condensation problems surfacing on windows and walls.

5) Winterize your home, inside out

During winter, especially during really cold spurts, avoid airing out your home by opening windows and doors. Instead, make sure your exhaust vents are working properly. The latter is all the more real when it comes to your dryer or range hood exhaust vents.

Clean your air exchanger’s filters that have, without a doubt, accumulated dirt during periods of inactivity. Also, check the air exchanger’s drain. It has to be perfectly hooked up and should never, under any circumstances, be dragging on the floor to prevent water from dripping out on account of the defrost cycle. 

Before it’s too cold to carry out the necessary work, take some time to inspect your home’s masonry walls, pointing, and foundation. Check the foundation and the surrounding area, including air intakes and exhausts. In case you spot minor cracks in the foundation, you can caulk them yourself or hire a foundation contractor to carry out the work, sealing and repairing all cracks. 

Pick up leaves and dead branches scattered around your yard or balcony. Doing so prevents sheltering ants and rodents. Ants can survive the colder months by hiding deep in the ground. If you see ants in your home during the winter, then it’s highly likely that they’ve built a nest in there.

6) Inspect your roof and chimney

Before the first snowfall, climb on top of your house to check the state of your roof. If need be, take care of any pressing repairs to limit damages and hire a chimney sweep to clean your chimney. Moreover, check the caulk around your chimney to make sure it’s sealed and there are no risks of water leaks.

Also, clean the gutters all around the edge of your roof by clearing the build-up of dead leaves and branches. That way, your gutters aren’t at risk of overflowing nor will your roof suffer from ice dams. Don’t forget to remove any hoses hooked up to the gutters, leaving them in place could mean rainwater won’t drain in case freeze sets in.

7) Prepare your yard and car shelter

Winterizing your backyard is just as important: 

• Put away your outdoor furniture and BBQ

• Empty garden hoses and store them

• Shut the exterior water valve to prevent water from freezing

• Shield your bushes and shrubs with wrap-around covers, cut tree branches that are likely to be hazardous over winter

• Use solid anchors for your car shelter

• Mow your lawn before winter

You can keep mowing your lawn up until October or November. Continuing to water your lawn will promote rooting over the wintertime. Also, fertilize your grass in September or October. That way, your grass can start storing fertilizer for springtime.
