When Is It Time to Replace Your Windows?
Windows don't last forever. Over time, seals break down, frames deteriorate, and energy efficiency drops. If your home has windows that are 15–20 years old, replacement can dramatically improve comfort, reduce energy costs, and boost your home's value.
At Cosello Construction, we specialize in both full-frame and insert window replacements. Full-frame replacement removes the entire window including the frame — ideal when there's structural damage or you want to change the window size. Insert replacement fits a new window into the existing frame — faster, less disruptive, and more affordable when frames are in good condition.
