Paul Despenas: The home was built in the late 1970’s and the windows had seen better days. At some point wood just stops holding paint and the exterior sills and casings start to deteriorate. Those are the easy fix. It’s when the window sashes start to deteriorate, it is past the time to start looking for new windows. When you can see wood rot on the sills, casings and sashes it is allowing water and air to infiltrate into the rough opening of the home causing structural damage and mold. This also allows plenty of the energy to go right out the windows!! EcoSmart Windows are custom built to fit into the existing opening like a glove.
