Why You Should Winterize Your House

It’s important to winterize your house each year to save on heating costs and prevent potential damage to your furnace, plumbing and roof. Plus, you can keep your house safe by preventing falling ice or falls on ice.

When to Winterize Your House

Winterizing your home is a process, but you should wrap up any outdoor work in the fall before it gets too cold and dangerous to work outside. Start checking your snow removal equipment as you winterize your lawn. You can tackle the indoor projects last.

Furnace Tune-Up

This one’s easy. All you have to do is call to your HVAC professional and schedule a time for them to come out. An annual tune-up keeps your furnace running efficiently. If you’re handy, you can do some furnace maintenance yourself.

Check Your Plumbing

Do you have any plumbing in a cold basement or unheated crawlspace? This might not be top-of-mind when you consider how to winterize your home, but it is important as the temperature drops. Wrap these pipes with pipe insulation, including heat cable under the insulation, to avoid frozen or burst pipes.

Check for Air Leaks

If your house feels drafty, check the weather-stripping around doors. It might be time to replace it.

Prevent Ice Dams

Making sure attic vents are clear and install heat cable on the roof to help keep ice dams from forming. Ice dams can cause a large amount of damage if left unchecked.

Check Your Roof

Loose or missing shingles invite roof leaks due to melting snow. This can be done with a quick visual inspection. Repairing issues is something best left to the pros.

Add Insulation

An extra layer of insulation in attics or crawl spaces can pay huge dividends in energy savings. Blown-in insulation is the best bet here. You can hire a company to do it for you or you can rent the equipment from some home improvement stores.

Clean Gutters

Leaves and debris in gutters and downspouts restricts the flow of water from melting snow. This leads to ice build-up in the gutters and eventually ice dams. It’s good to get these cleaned out before winter hits. Just make sure to do it after most leaves have fallen from your trees, otherwise you’ll have to do it again.

Get Your Snow Blower Ready

The first blizzard is not the time to make sure your snow blower is in good working order. A warmer fall day is a great time to start up your snowblower, make sure it has gas and the engine oil is good to go. Air up the tires if your model has pneumatic ones.

Stock up on Salt and Sand

When thinking about how to winterize your home, consider the safety of the people using your sidewalks. Be ready with salt or a DIY ice melting compound and sand for traction.

Sprinkler systems need the water blown out of them before winter freeze-up. If you have an air compressor you can DIY and save on the service fee. Save big bucks by blowing out the sprinkler system yourself.

Have you flushed your water heater lately? This important chore should be done at least once a year to remove sediment that accumulates on the bottom of the tank. That’s especially true if you live in a hard-water area.

The task is easy to ignore because it’s out of sight, but built-up sediment reduces the heating efficiency of your water heater and costs you money. Learn how to drain water heater fluid and get your water heater running like new.
