The overhead problem in museums and galleries
Track lighting and ceilings over exhibits collect dust that can settle on displays.
What to clean first
Track Lighting Cleaning
Track lighting cleaning removes dust and film from track rails, light heads and lenses used to spotlight merchandise, artwork and dining areas.
Vaulted and Cathedral Ceiling Cleaning
Vaulted ceiling cleaning removes dust and cobwebs from the high, sloped ceilings of sanctuaries, lobbies, venues and showrooms, along with the beams, fixtures and ledges within them.
Skylight Interior Cleaning
Interior skylight cleaning removes dust, insects and film from the inside glazing, diffuser panels and light wells of skylights, restoring natural light.
Crown Molding and Upper Trim Cleaning
Crown molding cleaning removes dust and cobwebs from crown molding, cornices, picture rails and decorative upper trim.
Supply Register and Diffuser Cleaning
Supply register and diffuser cleaning removes the dust, lint and grime that collects on the face and visible fins of the vents that blow conditioned air into a room.
Recommended schedule
