Weatherization Buyer's Guide

Why "weatherize" my house? Tightening up a home can dramatically lower your heating and cooling bills by as much as 30%, and simply help you feel more comfortable in your home year-round. A typical house, regardless of age, has countless nooks, crannies, and corners through which air escapes or comes drafting in — around doors, window panels, chimneys, around AC & ventilation covers, even between and at the edges of floorboards. Fortunately the tools at your disposal to fix the problem are just as varied, from caulk (for smaller gaps), to foam (for larger gaps), to tape, to weatherstripping. For more information on how to locate and seal your home's hidden air leaks, consult the Do-It-Yourself Guide to ENERGY STAR® Home Sealing from the U.S. Environmental Protection Agency .
