Yarmouth homes face a unique dual threat. In Yarmouth Port, the dense shade and humidity create a breeding ground for wood rot. We frequently find window sills that look fine on the outside but crumble to the touch because the previous installer relied on caulk instead of proper flashing. In South Yarmouth and Bass River, the salt air attacks standard aluminum spacers and lock mechanisms, causing seal failure (foggy glass) and seized hardware.

If a contractor tries to sell you a “simple swap” insert window without checking the rough opening, they are likely trapping moisture inside your walls. This leads to structural decay that is invisible until it is catastrophic.
