Window Leaks, Mold, Weathering

Basement Window Replacement

Basement windows present a particular challenge when it comes to window replacement. They include all the features of a regular window in a smaller space, usually with a thin profile frame to maximize sunlight exposure. Most homeowners choose to go with either a slider window or a full glass window for their basement windows although they are available in other varieties such as awning basement windows, bay basement windows etc.

Window Well Installation

Windows and window wells that are rusted and corroded can allow leakage from rain and snow, which can cause mold, mildew and other problems. Leaves, dirt and other debris can also clog the window well, causing flooding in the basement. Replacing your windows and window wells can prevent basement water problems caused by leaky basement windows.
