What We Do

Safe Conservatory Roof & Frame Cleaning

Conservatory cleaning requires a different approach to general jet washing. Polycarbonate panels, sealed glass units and uPVC frames need low-pressure, detergent-led cleaning that removes algae and grime without risking structural damage. We have the right equipment and the right chemicals for the job.

Common Questions

Conservatory Cleaning FAQ

Is it safe to jet wash a conservatory roof?

Direct high-pressure jet washing on polycarbonate or glass conservatory panels is not recommended — it risks cracking panels, forcing water into seals and damaging flashings. We use a soft wash technique with specialist detergents and a low-pressure rinse, which is far safer and more effective for conservatory roofs.

What is causing the green patches on my conservatory roof?

Green patches are algae colonies that take hold in shaded, damp areas — typically north-facing conservatories or those under overhanging trees. Algae degrades polycarbonate over time and reduces light transmission. Our biocide treatment kills the algae at the root and slows regrowth.

Can you clean both the inside and outside of conservatory glass?

We specialise in external cleaning. Internal glass cleaning can be arranged by separate agreement — let us know when you book and we will advise on what is possible.

Will cleaning improve the light inside my conservatory?

Yes, noticeably. Heavy algae and dirt coverage on polycarbonate roofing can reduce light transmission by 30–50%. After cleaning, most customers immediately notice how much brighter the space is.

How long will the clean last?

With our biocide anti-algae treatment, most conservatory roofs stay clean for 2–3 years. North-facing roofs or those under trees will see regrowth faster. We recommend an annual check and retreatment every 2–3 years.
