The Window Nerd has been serving the southeastern Pennsylvania and central Jersey areas for more than three decades. Take a drive with our owner (whose been in the industry for more than 40 years), and it's hard to find a neighborhood that doesn't house at least one of his customers. Over our history, we've seen every window and door configuration and managed every construction hoop imaginable. We know what works, what doesn't, and how to get the job done right the first time.
