Dirty skylights let in less light and attract moss that causes permanent damage. We restore your skylights to full clarity — no streaks, no residue.
Get Your QuoteNeglected skylights don't just look bad — they degrade faster and cost more to fix.
Skylights are installed to bring natural light into your home. A layer of grime, algae and pollen dramatically reduces how much light passes through — and because the buildup is gradual, most homeowners don't notice until the skylight is cleaned and the difference is obvious.
Skylights sit flat or at a low pitch, which means moisture and debris collect on them far more readily than on vertical windows. Moss and lichen are particularly aggressive — their root structures work into micro-cracks in the glass or acrylic surface and the frame, causing damage that can't be reversed by cleaning alone.
Mineral deposits from hard water and organic tannins from leaf debris create stubborn staining that etches into skylight surfaces over time. The longer it's left, the harder it becomes to remove. Caught early with regular cleaning, water staining stays on the surface — left too long, it becomes a permanent mark.
A professional clean every six months removes the organic matter that causes degradation before it can take hold. Keeping the glass and frame clear of moss, lichen and debris protects the seals, prevents frame corrosion and keeps your skylights performing exactly as they should — clear, bright and watertight.
A thorough exterior clean that restores clarity and protects your skylights from damage.
We clean the full exterior surface of your skylights — glass or acrylic, flat or pitched. Moss, lichen, algae, bird droppings, pollen and water staining are removed using the right tools for the surface type. We take care around frames and seals to avoid causing damage, and finish with a streak-free rinse so your skylights are crystal clear.
Already up on the roof? We can also clean your gutters and solar panels while we're there.
We recommend getting your skylights cleaned at least every 6 months, similar to windows. In Melbourne's eastern suburbs, skylights are particularly prone to moss and lichen growth due to the combination of moisture and shade from surrounding trees — especially in leafy suburbs like Kew, Balwyn, Camberwell and Doncaster. Moss and grime don't just block light — they hold moisture against the glass and frame, which accelerates deterioration over time. A twice-yearly clean in autumn and spring prevents buildup from taking hold and keeps your skylights letting in maximum natural light all year round. If you notice moss beginning to develop between cleans, it's worth booking sooner rather than waiting — the longer it's left, the harder it is to remove without risk of surface damage.
Skylight cleaning costs depend on how many skylights you have, how dirty they are, and how accessible they are on the roof. A single flat skylight on a single-storey home is priced differently to several steeply pitched skylights on a double-storey property with heavy moss or lichen buildup. Additional services like gutter cleaning or solar panel cleaning can often be bundled at the same time since we're already on the roof, which can make the overall job more cost-effective. Every job is different, so we don't quote a flat rate — instead we assess your property and provide a tailored quote. Get in touch for a free fast quote and we'll get back to you promptly — most quotes are turned around the same day.

"Lachie was a lovely, polite young man who did a great job cleaning my top-level exterior windows and skylights. As a bonus, he also cleaned the ground-level windows and doors at no extra charge, which was greatly appreciated."
"Thank you to Lachie for cleaning my skylights! Respectful and even offered to clean some additional skylights without changing his price."
"Wonderful window clean by Lachie, who also noticed our gutters, sky light and solar panel needed attending and offered to do them too. Agile and safe on the roof."
"Lachie did a professional job. Two story home, hence, top windows are difficult to get too which Lachie managed with ease and safety. He was on time, professional and SMS reminders leading up to the appointment were helpful. I would highly recommend Lime Window Cleaning."
