Sealing Air Leaks Outside The House – 3

Yesterday we found and repaired air leaks around both the plastic encasement for the electrical cabling entering our home as well as what we think was either telephone or TV cabling.

Today, two more air leaks are discovered.

First, when we moved into this house two years ago we had a satellite dish installed for our television. Well, look at this.

Less than two years since that time and we can see the caulking used for the satellite dish is not properly sealing the cabling. It has not shrunk; rather, it was simply not properly applied in the first place.

So, we remedy that by applying more of the caulking we have been using in the past two articles to seal air leaks outside the house.

Now, here is the bay window for our dining room.

You cannot see it in the above picture, but you can see the cracked original caulking in the close up below.

The air leak is not at the window part of the Bay window; rahter it is at either side of the part which is below the window. So, remedy that by applying new caulking to seal all of those air leaks.

I would have liked to have removed all of the old caulking but time was running out on me as I had an errand to run, so I simply filled in the cracking original caulking. When I have more time next year I will do a more proper job. However, this will do fine for this winter.

So, we found in our slow examination of the outside of our home air leaks around a water pipe, the plastic casement for the electrictal cable, the old TV cable, the new satallite dish cable and around the bay window.

What different air leaks can you find, have you found and fixed in your own home?

Start looking now. Winter is coming.

    As I noted in the first installment of this article, fresh-air makeup vents for your furnace is a potential leakage point. Many newer furnaces & homes have this type of arrangement, so it’s a good idea to check the point where it punches through the wall. It’s also a good idea to find where the cold air makup leads to (it should be very close to your furnace so as to supply combustion air for your furnace). Ideally, you will have this the end of this vent & your furnace in a sort-of closed off room so that in the Winter, this cold air vent doesn’t freeze your basement.

    Also, drier vents are a biggie. They can become clogged with lint which causes the check-valve to not close, thereby letting in cold air via your drier. The flaps inside can also crack or break. You can tell if this is an issue in your home when you open up your clothes drier during very cold weather – if the inside of the drier is colder than the interior of your house … you have a problem.

    Keep the flaps clear of lint, use a thermal air vent line instead of the standard white plastic vent, and use the expanding foam + caulking trick around the vent-hole in the wall.
