Factory Skylight Cleaning

If your factory, warehouse, or workshop has skylights, there’s a good chance they’re doing far less than they should. Dust, dirt, mould, and lichen accumulate quickly — and over time block out a significant portion of the natural light the skylights were installed to provide.

The result is artificial lighting working harder than it needs to, running longer hours to compensate for light your skylights should be delivering for free. That’s a direct and ongoing cost to your energy bill.

A professional clean restores full light transmission in a single visit — better natural light, lower power costs, and a brighter working environment without changing a thing about the facility.

Skylight cleaning on industrial roofs requires the right access, equipment, and technique. Our vehicles are custom-built for this work — pressure cleaning systems powered directly from the vehicle engine, onboard water tanks with boiler units for hot water delivery, and up to 100 metres of hose reel keeping all heavy equipment on the ground where it belongs.

Safe roof access
Our technicians work on the roof wearing fall arrest harnesses throughout. Access is assessed and arranged before work begins — your facility and your staff are not at risk.

Downpipe and stormwater protection
Downpipes are redirected before cleaning begins to prevent wastewater, debris, and cleaning solution from entering stormwater drains or rainwater tanks. Specialist filters capture any debris runoff into gutters.

Chemical pre-treatment where required
For skylights with heavy lichen, mould, or ingrained grime on fibreglass or polycarbonate panels, a cleaning solution treatment is applied first to soften the contamination before pressure washing. This protects the skylight surface from excessive pressure while ensuring a thorough result.

Pressure washing
Water pressure is carefully calibrated to the skylight material — enough to restore full clarity without causing crazing, cracking, or surface damage to fibreglass or polycarbonate panels. The result is maximum light transmission restored across the full skylight area.

We specialise in industrial and commercial skylights on factories, warehouses, and workshops — we don’t clean small residential skylights.

• Polycarbonate roof panels
• Translucent roof sheeting
• Ridge and hip skylights on industrial roofs
• Continuous skylight runs on warehouse and factory roofs

Most facility managers don’t think about skylights until they’re obviously dark or damaged. But the impact of gradual soiling is cumulative — light levels drop incrementally, artificial lighting compensates automatically, and the energy cost accumulates quietly in the background.

A professional skylight clean typically restores light transmission significantly — in heavily soiled cases, the difference inside the facility is immediately obvious. For large warehouses and factories with extensive skylight coverage, the reduction in artificial lighting hours can represent a meaningful and ongoing saving on energy costs.

Combining skylight cleaning with a scheduled maintenance agreement means the light levels — and the savings — are maintained consistently rather than recovering from a long period of neglect each time.
