Why It Matters

Why We Publish Before-and-After Photos

Adjectives are cheap; photographs aren't. Every image in this gallery comes from an actual Service-Tech project, organized by service line below. The "before" shots also serve a purpose for facility managers: they show what deferred maintenance actually looks like inside systems you rarely open — the grease depth in a duct that hasn't seen NFPA 96 service, the sediment in a tower basin, the dust load on rafters forty feet up. If any of these befores looks familiar, that's your sign to book the after.

Combustible Dust

Industrial Cleaning

Dry ice blasting, combustible dust removal, plant deep cleans, and high dusting. See the industrial cleaning service line.
