Don't let your home lose valuable thermal energy when temperatures drop. Find your insulation weak spots and plan a few hours to shore them up! Take a look at the complete list of which parts of your house need insulation, and why it's important to get the project done before winter.
When temperatures start to drop below freezing, your plumbing may be in danger. Pipes where water tends to linger, unprotected by the insulation that guards the rest of your home, can freeze on particularly cold nights. The expanding ice can even crack pipes and flood homes. Make sure that pipes in cold areas are properly insulated and protected when you expect the temperature to drop below freezing.
Heat rises, and to keep it inside your house, you need to make sure your attic space is properly insulated. That means taking care of empty corners and shallow areas where blown insulation may not have settled correctly. Smaller cracks can also be treated with foam insulation.
Remember your attic always needs an appropriate amount of ventilation. Otherwise, condensation builds up and can cause many problems. Don't close up any vents without first consulting an expert.
If your garage has a more active role in your life, then insulation is a good idea. Basic batt insulation and garage door insulation can go a long way here, and it's a good excuse to clean up the garage while you're at it.
Doors and Windows
Weatherstripping around doors and windows keeps cold air out and warm air in. Without weatherstripping, small spaces will leak air and cost you on monthly heating bills. Check the weatherstripping around your house. If it's worn or missing, then it's time for a replacement.
Like your unprotected pipes, you don't want outdoor faucets to suffer from ice expansion. Fortunately, installing a frost-proof outdoor faucet is a pretty quick project, and always remember to disconnect your hose before the cold comes.
Vents and Ductwork
Vents, especially old ones, may open your house up to outside temperatures if they're not properly protected. The good news is that there are plenty of ways to protect your ductwork. If you live in a colder-than-usual climate, consider fully insulating your ducts.
Air Leakage Points
Outlets, switches and light fixtures can allow air pass through. Over time, these small gaps and leaks can lose a lot of heat. Fortunately it is an easy insulation project to properly seal them will prevent that problem. Use minimally expanding foam to seal any gaps.
