Plastic Window Seals

Our electric bill arrived today. I had heard bad omens from a few friends of mine, but it was still a shock that we owe more than double what we did last month. We resolved to do whatever we could to bring that number down. Tonight's project: sealing up the bedroom windows. Plastic window sealing kits can be found at your local hardware store.

If, like us, your blinds are screwed directly into the window frame, you'll have to remove them. The office and spare room will have to do without blinds for the rest of the winter, as I don't want to screw through my brand new pristine seal. Luckily, the master bedroom's blinds are affixed to the wall above the window.


The kit comes with a big plastic sheet and some double-sided tape.


Tape along each side of the window.


After 15 minutes, remove the protective backing from the tape on the top of the frame. If you're doing multiple windows, tape them all, and by the time you're done with the last, the backing on the first can safely be removed.


Measure out and cut a piece of plastic, making sure there will be a few extra inches on each side.


Stick the plastic to the top of the window, then remove the protective film from the tape on the sides and bottom of the frame, and attach the plastic there. It's okay if there are wrinkles.


Using a blow dryer on the highest setting, heat the plastic, starting with a corner. It will shrink (immediately), forming a tight seal around the window. When you're finished, the plastic will be totally invisible except for reflections. It doesn't look tacky like I thought it might.


Put your blinds back, if you can. Enjoy your draft-free window, but don't touch it!
