Conservatory roofs quietly collect green algae and grime that block the light and leave the room feeling dingy. We clean the whole thing — roof panels, frames, finials, ridge and glass, plus the often-forgotten box gutters — and bring the brightness back.
Across Chelmsford and Essex we clean conservatories of every age and style, from older glass-roofed Victorians to modern polycarbonate lean-tos and the smart solid-roof conversions going into homes around Springfield, Great Baddow and Writtle. If the light coming through has dulled and the frames have gone grey and streaked, a proper clean makes a striking difference.
It's the parts you can't easily reach that cause the trouble. Polycarbonate and glass roofs face the sky all day, so they're the first thing to go green — algae and moss spread across the panels and along the glazing bars, cutting the light long before anything else looks dirty. Cleaning the roof is what makes a conservatory feel bright again.
The bigger hidden problem is the box gutter (or valley gutter) that runs along the top of the conservatory where it joins the house. It fills with leaves, moss and debris, blocks, and then overflows — and because it sits behind the roofline, the water often finds its way inside, causing leaks and damp on the wall and ceiling below. It's a job many window cleaners skip entirely. We clear and clean these as standard, so the conservatory stays watertight as well as bright.
Conservatories need a gentle touch, not brute force. We clean the panels and frames using a pure water-fed pole and soft brushing, which lifts away algae and grime and leaves the glass and uPVC spotless without leaving streaks behind. There's no harsh pressure that could disturb the seals between panels or damage the polycarbonate. The finials, ridge and trickier detailing are cleaned by hand so nothing is rushed or missed.
We clean every common conservatory style — Victorian and Edwardian designs, lean-to and gable-front conservatories, and orangeries. That covers both polycarbonate and glass roofs, as well as the frames and cladding of solid and tiled-roof conversions where the roof itself no longer needs cleaning but the frames and windows still do. If you're not sure which roof you have, send a photo and we'll tell you — and price it.
Conservatory cleaning starts from £80 for a small lean-to exterior. A typical clean including the roof and box gutters is usually £100–£180, depending on the size and style of the conservatory and how easy it is to reach. Interior glass cleaning is available as an extra. Full breakdown on our pricing page — or send a photo and your postcode for an exact figure, usually the same day.
Yes — the roof is where most of the difference is made. We clean the roof panels, whether glass or polycarbonate, along with the ridge, finials and frames. The roof collects green algae and grime that block the light, so cleaning it is what really brings the brightness back into the room. We clean the exterior glass too, with interior glass available as an option.
Yes. We clear and clean the box and valley gutters where the conservatory meets the house. These often-forgotten gutters block with leaves and debris and overflow, which can cause leaks and damp inside — and they're a job many window cleaners skip. Clearing them is included as part of a full conservatory clean.
We don't use harsh pressure on conservatories. High pressure can disturb the seals and joints between panels and damage polycarbonate. Instead we use a pure water-fed pole with soft brushing for the panels and frames, and detail the finials and ridge by hand. It's a careful, gentle clean that protects the structure.
