Review on Caulking Cord by M D Building Products: A Reliable Solution for Sealing Gaps and Cracks by Bobby Montoya

I usually have to balance each fall at the top of the stairs to close the plastic windows. No longer! Instead I put it all the way around the inside edge of the storm windows and it's just as warm as the old plastic method. Safer, easier and reusable. We used it on the windows of our old farmhouse as kids and I'm so glad it's still around.
