Our Drones Let You See Your Building from Above

Drones Take Our Services to New Heights

Douglass Colony takes care of every building as if it were our own. With our unmatched blend of people, history, innovation, and quality we take on the jobs that others won’t. From re-roofing and waterproofing that can give a building new life to service and maintenance that can save building owners big money, Douglass Colony delivers nothing but the finest results — every time.

Harnessing our drone capabilities, we can provide you with a bird’s eye view of your building. This way, we can easily pinpoint potential risks before they become a problem, all without needing the manpower to safely get up on your roof and inspect it ourselves.

Check out this video that shows some of our capabilities and how we put our drones to work for you.
