Just the other day we were starting to think about winterizing our home for the season, when we got a great tip from one of our favorite home improvement gurus, Lou Manfredini. Lou suggested that as an alternative to covering drafty windows with plastic, caulk them with a temporary and removable sealant such as Zip-A-Way. A removable sealant is a better alternative to unsightly plastic and is great for oversized or irregular windows…We have the issue of windows that are too large for plastic, and honestly we really hate the damage that can be incurred from the tape that adheres the plastic to the walls and windows. A removable sealant solves that problem by applying it only to the cracks, joints and edges of a window frame. The provides a fast drying seal that lasts 3 to 6 months and is clear but can be painted if desired.
One of the downsides, however, is you lose the extra air buffer that you'd typically get between plastic and windows. This air pocket acts as an insulator and can be very beneficial for those with single-glazed windows.
Zip-A-Way can be purchased through Amazon – a 12 pack of 10.1oz runs $51.69, or a similar product, Dap Seal ‘N Peel, can be bought as individual tubes for $6.49. Both products are also readily available at most hardware stores.
