Bob Flake
Ducts of Metro East - Millstadt, IL I was just about to occupy our new “high end” new construction home. Although cleaned, but not quite to our standards regarding dust, debris from plaster, etc. My timeline was limited, yet Shawn adjusted his schedule to accommodate our concerns. He and his co-worker were timely, they worked non-stop for 4 hours and our home was cleaned!! They created little dust themselves, and cleaned up thoroughly. I HIGHLY recommend 👍🏻 without reservation! Bob Flake Waterloo
