The overhead problem in warehouses and distribution
Dust settles on joists and falls onto inventory and packaging.
Access requires lifts, so cleaning is often deferred for years.
What to clean first
Joist and Truss Cleaning
Joist and truss cleaning removes dust and cobwebs from steel bar joists, web members and roof trusses.
Beam and Rafter Cleaning
Beam and rafter cleaning removes the dust, cobwebs and grease that collect on top of exposed wood and steel structural members.
High-Bay Light Cleaning
High-bay light cleaning removes the heavy dust that coats fixtures hung 20 to 40 feet or more above warehouses, gyms, manufacturing floors and big-box stores.
HVLS Big Fan Cleaning
HVLS fan cleaning removes the heavy dust that coats the large airfoils and hubs of high-volume low-speed fans in warehouses, gyms, hangars and event venues.
Exposed Ductwork Exterior Cleaning
Exposed ductwork exterior cleaning removes the dust, cobwebs and grease film that settle on top of and along visible ducts in open-ceiling buildings.
Ceiling-Mounted Unit Heater Exterior Cleaning
Unit heater exterior cleaning removes dust and debris from the outside cabinet, louvers and fan guard of ceiling-hung heaters in warehouses, shops and service bays.
Hanging Sign and Banner Cleaning
Hanging sign cleaning removes dust and cobwebs from suspended aisle markers, department and wayfinding signs, and hanging banners.
Recommended schedule
