Weatherization and Insulation Technicians
Where the insulation meets the cold!
Sealing the envelope of your home—outer walls, foundation, doors, ceiling, windows and floors—from air leaks is one of the simplest and most cost-effective ways to increase comfort and energy efficiency. Air sealing reduces drafts, controls moisture, keeps out pollutants and improves overall comfort. It also provides a more healthful living space and provides a quick payback in investment. Efficiency Maine provides rebates of up to $600. for such work.
Caulk is a flexible material used to seal air leaks through cracks, gaps, or joints less than 1-quarter-inch wide between stationary building components and materials. For components that move -- doors and operable windows, for example -- weatherstripping is the appropriate material.
Before caulking air leaks in an existing home, you will need to detect the leaks and assess your ventilation needs to ensure adequate indoor air quality. In addition to sealing air leaks, caulking can also prevent water damage inside and outside of the home when applied around faucets, ceiling fixtures, water pipes, drains, bathtubs, and other plumbing fixtures.
