Our Story

Custom Exteriors was founded in 2018 by John Kinyon and Mike O’Brien, each bringing decades of industry experience. Mike has an extensive background in roofing and gutters, and John comes with unmatched skills in the window and siding world. They joined forces to create a single exterior remodeling company able to deliver a full suite of exterior services, all under one roof. 

Their shared vision was clear from the beginning: to change exterior remodeling in their community. They want to do this by making it not only easier but also better. This vision is part of the core values that define Custom Exteriors today.
