A good percent of the air that is circulated through your home is lost due to leaks and holes in your door and window casings. Proper sealing (and waterproofing) can help save money on heating and cooling, and keep your home’s building envelope free from moisture. Poor installation of doors and windows, in addition to poor quality materials, is the biggest cause of water infiltration and structural rot.
