When it comes to looking for spots to save in your home, gaps and cracks around windows and doors may not be the first things that come to mind. But they should be! Sealing up those sneaky spots can help keep the warm air in during the winter and out during the summer, improving your home’s energy efficiency. The best part: you can do it yourself! And we promise, it won’t be a Pinterest fail.

If this is your first time attempting DIY fixes around your home, you might be wondering where to get draft-proofing supplies. Most home hardware stores carry v-seal and foam weather stripping, as well as foam insulator pads for your outlets and light switches that are on external walls.

Foam weather stripping step-by-step:

1. Once you’ve identified the area you want to seal, make sure it’s nice and clean before you start.

2. Measure out the length of the area you’re looking to seal. For example, if you’re sealing around your door, measure the door from top to bottom.

3. Cut your foam weather stripping to measured length, and peel off the plastic from the adhesive side.

4. Stick the adhesive side of the foam weather stripping to the area you want to seal. Double check the adhesive is applied properly all the way from the top to the bottom.

Viola! Foam weather stripping installed in just four steps. For the full DIY videos on v-seal, foam insulator pads, thermal heat detectors and more, check out our DIY playlist on YouTube.
