Serving Herndon
Two People You Will Actually Know
Home Exteriors Energy Consultants is a father-and-son business serving Herndon and the rest of Fairfax County. Mark Horner, who founded the company in 2007, meets every homeowner personally and writes every estimate. You will not be passed to a new salesperson or a scheduler you have never met.
His son Hadley runs operations, customer service, scheduling and production. Once your project is installed, Hadley visits to make sure everything is exactly right. If you want to know more about us first, our about page tells the story.
