Conservatory Roof Cleaning
Glass and polycarbonate conservatory roofs cleaned of algae, moss and grime — including the valley gutters and finials — to let the light back in. Inside-out options available.
Get a quoteuPVC windows, doors, soffits and fascias revived and protected — lifting discolouration and reaching the spots you'd rather not. We also restore sun-damaged, oxidised uPVC where a clean alone won't fully bring the colour back, and clean conservatories inside and out.
We choose the technique to suit the surface — soft washing or chemical-free steam where pressure would do harm, controlled pressure washing where it won't. That's how upvc cleaning gets a lasting result without damage.
Left to spread, moss, algae and lichen trap moisture against your roof, walls and surfaces and shorten their life. Regular cleaning is the cheaper, greener way to stay ahead of remedial building work.
Fully certified to disinfect and prevent regrowth, applied with minimal impact on occupants, pets and wildlife.
Owner-led and fully insured, known across Chichester and West Sussex for careful work and fair pricing — domestic and commercial equally welcome.
uPVC is the first part of a house to show its age. Long before the brickwork looks tired, the window frames, doors, soffits and fascias have gone grey with traffic film, green with algae and streaky with weathering — and because it is all up at eye level and along the roofline, everyone sees it. We bring it back. Our uPVC cleaning lifts the grime and growth off every plastic surface and restores that original bright white finish:
Because it is all cleaned at low pressure with a soft-wash treatment, the seals, gaskets and the plastic itself are never stressed — just lifted clean. While we are up at the roofline it is the natural moment to clear the gutters, soffits and fascias properly too, and many customers bundle it with a window clean so the glass and the frames come up together.

A conservatory only feels light and airy while its roof is clear. Glass and polycarbonate roofs sit flat to the sky and shaded by the house, so they collect algae, moss and grime faster than any other surface — and once the valley gutters and the panels green over, the room below goes dim and the gutters start to back up. We clean them properly: the algae, moss and grime cleared off the glass or polycarbonate, the valley gutters and finials flushed out, and the light let back in. It is all done by gentle reach-and-wash soft washing, never high pressure, so nothing is forced past the roof bars or the seals. Conservatory roof cleaning is the one specialist add-on we offer alongside the uPVC round — see the full conservatory roof cleaning service for glass, polycarbonate, valley gutters and inside-out options.


Not all uPVC dirt is dirt. Grey filming is airborne grime and traffic film; green is algae feeding on the damp, salt-laden air off the sea around West Wittering, Bracklesham and Selsey; and a dull yellow cast is the surface oxidising in sun and salt. Our clean lifts all three — the grime, the algae and the oxidised film — and brings the original bright white back. It is honest cleaning, not a respray: we bring back the finish that is there rather than coating over it, so the result is your own uPVC looking as it did when it went in. On the most exposed coastal frames a regular clean keeps the white bright and stops the green and grey ever taking a real hold.
Some frames, though, have had years of sun and salt and the surface itself has oxidised — gone chalky and yellowed in a way no amount of washing will shift. For those we offer a dedicated uPVC restoration treatment that goes beyond cleaning: it lifts the dead, oxidised layer and brings the depth of colour back, so badly sun-damaged windows, doors and fascias look like new again without the cost of replacing them. If your uPVC is past what a clean can fix, ask us about restoration when we quote.
