Green, grimy glass and a dull roof ruin the view. We clean the roof, frames and glass so your conservatory feels bright again.
Conservatory cleaning in Milton Keynes usually comes down to one thing — algae on the roof and green film on the glass, worst on north-facing or tree-shaded builds. We clean the roof, bars, finials, frames and glass externally as standard, using soft brushes and low-pressure pure water so seals and gaskets are never blasted. Stubborn green growth is treated with a biodegradable cleaner that's safe around plants and pets, then rinsed clear. Your conservatory ends the day brighter, warmer in use, and far less slippery on the roof — exactly what it was built for.
Conservatories across Milton Keynes go green and dull within a year or two because algae takes hold on north-facing and tree-shaded roofs — and a regular clean restores the light, removes the slip risk and extends the life of the roof and frames.
The problem isn’t just cosmetic. Algae on a polycarbonate or glass roof makes the surface slippery and, in winter, dangerously so. It blocks light, so the room stays cold and you spend more heating it. And left long enough, algae and moss can work into the seals and gaskets, causing the kind of damage that’s expensive to put right.
A regular conservatory clean restores the light, removes the slip risk and extends the life of the roof and frames. Across Newport Pagnell, Bletchley, Wolverton, Stony Stratford and Woburn Sands, it’s one of the most transformative jobs we do — a dull, green roof becomes a bright, clear one in a single visit.
Every clean covers the roof, the bars, the finials, the frames and the glass — externally as standard — using soft brushes and low-pressure pure water so seals and gaskets are never blasted. We can also quote for an internal clean and a gutter clear while we’re there.
Every surface that’s gone green or dull gets attention, because cleaning only the glass leaves a clean pane sitting in a filthy frame. We use soft brushes and low-pressure pure water on the roof and glass, so seals and gaskets are never blasted.
High pressure is the enemy of a conservatory — it forces water past seals, degrades the silicone and can crack polycarbonate — so we don’t use it. For stubborn green growth we treat with a biodegradable cleaner that’s safe around plants and pets, then rinse it clear.
We can also quote for cleaning the inside of your conservatory, including roof glass and frames, and for clearing the conservatory’s own gutters while we’re there. Just mention what you’d like when you request your quote and we’ll build it into the price.
A green, dull roof, cloudy streaky glass, algae-stained uPVC frames and a slippery roof are the four problems we fix most — and all four are sorted in a single visit with soft brushes and the right treatment.
Algae and moss build up on polycarbonate and glass roofs, worst on north-facing or tree-shaded builds. Soft brushes and the right treatment lift it without damaging the surface, and the difference in light is immediate.
Cloudy, streaky glass is usually down to hard water and dust that’s been left to bake on. Pure-water rinsing lifts the mineral deposits and leaves the glass clear and streak-free. Green and black staining on uPVC frames is algae and mould that’s taken hold in the shaded corners and silicone — a soft brush and pure water lift it cleanly before it can stain the plastic permanently.
A slippery roof is a genuine safety issue in winter — algae on polycarbonate is like ice when it’s wet. A clean roof is a safe roof, and we can advise on how often yours needs doing based on its aspect and the trees around it.
A professional clean reaches the roof safely, uses the right pressure to protect seals and finishes in a few hours, while a DIY clean risks cracked polycarbonate, blown seals and a roof that’s still green at the top. For most Milton Keynes conservatories, a professional clean is safer and more thorough.
Cleaning a conservatory yourself usually means a hose, a long brush and a set of ladders up against the roof bars. It’s doable for the lower glass and frames, but reaching the roof safely is genuinely difficult — and the temptation is to lean a ladder on the bars, which can bend or crack them, or to blast the roof with a pressure washer, which forces water past the seals and can crack polycarbonate.
A professional clean uses telescopic, water-fed poles and harnesses where needed, so the roof, bars and finials are reached safely without a ladder resting on the structure. We use soft brushes and low-pressure pure water on the glass and a biodegradable treatment on stubborn algae, so seals, gaskets and polycarbonate are never put at risk.
The main trade-off is cost — a professional clean isn’t free, where a DIY scrub is. But a single cracked polycarbonate panel or a blown seal costs far more than the clean that would have prevented it, and the finish lasts longer because the whole roof, not just the bits you can reach, is done properly.
