Caulk is easy to install and one of the most cost-effective energy efficiency improvements. Caulk window frames and door frames inside the home to reduce drafts. Use long-lasting exterior caulk outside the home where a window or door frame meets brick, wood or siding. To ensure proper adherence and curing, the ideal condition for exterior caulking is the second or third dry day in a row with a temperature between 50 and 90 degrees Fahrenheit.

Any hole that leads from a basement or crawlspace to an attic is an energy waster. Heated air rises and can escape into the attic through attic doors, pull-down stairways, ceiling openings, plumbing vents or pipes, air ducts, open wall tops or electrical runs. Seal holes with caulk or spray foam where pipes, wires and vents enter or exit a home. Be sure to check behind and under sinks.
