Everything you want to know Frequently Asked Questions

Rain can wash away loose dust, but it rarely removes salt residue, bird droppings or stubborn grime properly. In many Perth homes, panels can still look dull or streaked after rain, which is why professional cleaning is often needed.

Many homeowners choose to clean panels before peak summer and again after dustier or wetter periods. The best time is usually when buildup becomes visible or when your solar output starts to drop without another obvious reason.

Common signs include visible dust, patchy buildup, bird droppings that do not wash away, streaks after rain or a drop in daily production. If your property is near the coast or in a dusty area, buildup can happen faster.

Over time, grime can become baked onto the glass and reduce the amount of sunlight reaching the cells. This can lower output, reduce efficiency and make the panels harder to clean properly later on. Regular maintenance helps avoid long-term buildup.

DIY cleaning can be risky, especially on double-storey homes or steep roofs. There are also risks around scratching the glass or using the wrong cleaning method. Many property owners choose professional cleaning for safety and peace of mind.

Professional cleaning uses PV-safe tools and methods designed to lift dirt without abrasive contact. The aim is to remove buildup thoroughly while protecting the panel glass and surface coatings from damage.

Yes, flyscreens and window tracks are included as part of a standard clean, not just the glass itself. Removing built-up dust and grit from tracks also helps windows open and close more smoothly.

In most cases, yes. Once the glass is cleaned we can apply a nanocoating treatment in the same visit, giving windows a protective finish that sheds dirt and water more easily between cleans.

A one-off clean is a great starting point, but most Perth homes benefit from a regular schedule to keep pace with dust, pollen and coastal salt. We can recommend a frequency based on your property's location and exposure once we've seen it.

We adjust pressure and technique to suit the surface, using gentler settings on older or more fragile brickwork and mortar joints. If you are unsure whether your property's brickwork can handle a full pressure clean, we can assess it on an initial visit.

Yes, pressure cleaning is one of the most effective ways to remove mould and moss from paths, driveways and building exteriors rather than just surface staining. Left untreated, mould can also make paved areas slippery and unsafe underfoot.

Yes, and it's a combination we recommend for surfaces prone to repeat staining. A nanocoating application straight after a pressure clean helps repel dirt, oil and moisture, so the surface stays cleaner for longer between visits.

Yes, larger accounts are managed through a consistent point of contact who understands your sites, access requirements and preferred scheduling. This keeps communication simple as work scales across multiple properties.

A service agreement sets a recurring schedule and locked-in pricing for ongoing work, while a one-off clean is a single visit with no ongoing commitment. Most commercial and strata clients move to an agreement once they have seen the results of an initial clean.

At minimum, ask for proof of public liability insurance and a Safe Work Method Statement for site access. We provide both as standard for every commercial and strata job, along with before and after documentation on request.
