BRRRRRR - It's cold - Change or replace those weather strips
Well it's that time of year and the temperature has plumeted. But the concept is the same in any extreme temperatures, either hot or cold. The weather strip on your door will keep cold air out, and your heating inside.
Same in the summer it will keep the heat from the hot scorching summer sun out, and your air conditioning inside. So make sure your weather strip is in good condition and if not change it or replace it. As the photo shows we needed to replace ours this year.
