This time of year can be just great here in Pennsylvania. However, you won’t get much fireside snuggling done if your chimney clogs or your roof springs a leak. And while prepping your home for winter weather isn’t much fun, once you do it, your peace of mind can last all season long.

Here’s a handy checklist to make sure the weather stays outside where it ought to be.

Furnace Follies
If you have a forced-air furnace, visually inspect the outside of your system, the ducts, and other points attached to the unit. Repairing potential air leaks is easy to do with a little duct tape. It’s also a great time to clean or replace the filter according to the manufacturer’s instructions. If you can reach them, vacuum off the blower blades while you’re in there.

Winter Weather Stripping
A common source of heat loss and drafty spaces is faulty door or window weather-stripping. Check for drafts by holding a lit candle a couple of inches from the seam. If the flame moves (and you’re sure it’s not the dog breathing over your shoulder) you could have a leak. Typically these are easier to replace entirely than “spot repairing” and kits for doing so may be found at any hardware store.

Chim Chim Cher-ee
Creosote is the black, scaly deposit left behind in wood-burning chimneys. It slows airflow and is an enormous fire hazard. While the chimney is cool, take a flashlight and look for build-up past the damper (at the mouth of the flue near the base of the chimney). If you burn a lot of wood during the season–or very resinous wood like pine–cleaning the chimney is an annual must-do. This is one repair where hiring qualified professionals is best because they have the proper tools and experience to make sure it’s done right.

Stormin’ the Doors
Operational storm doors and windows prevent additional drafts and save energy costs. Make sure the hinges are lubricated and adjusted so they close properly. If you have interchangeable glass panels, make sure to install them instead of leaving the screens over winter.

Rain Gutter Braining
Clean gutters help prevent many cold weather problems from arising, such as basement flooding, siding damage, and door and window leaks. Clean gutters also help keep your foundation dry and repair-free. Plus, if your gutters are holding too much water they can pull free of eaves and fall off at any time, posing a hazard to your noggin.

Show Your Best Siding
In some cases you’ll need to hire a professional to make siding (or paint) repairs, but you can easily inspect for cracks and separations, peeling paint, or other damage that’s not difficult to repair yourself. Usually, a little caulk and some paint do the trick. But don’t leave it to chance–or leave it too long–because when water gets behind siding it’s expensive to repair as well as a health hazard.

Put a Lid On It
If possible, check your roof close up. You can use binoculars to inspect safely from the ground. Look for missing tiles, cracked shingles, and “bald spots”. If you have a composition roof past its warranty, make sure to check for brittleness, a sure sign it needs replacing. Also, if you notice lots of asphalt granules in your newly spotless rain gutters, it’s a sign your roof is eroding and needs replacing soon. Lastly, make sure to check the flashing around the edges of the roof for damage.

Taking just a few minutes this time of year to inspect your home for these common cold weather entry points and it will prevent more costly repairs, reward you with a lower energy bill, and help you have a relaxing holiday season.
