Frequently Asked Questions

Can you clean all types of conservatory roof?

Yes — we clean polycarbonate, glass, and solid roof conservatories. Polycarbonate roofs are the most common and often the most affected by green algae. Each material needs different techniques and pressure, and we select the right approach to avoid damage.

How do you remove the black or green marks from a conservatory roof?

Black and green marks are almost always algae or lichen. We apply a specialist biocide solution that kills the growth at the root, then gently rinse the panels. The result is a bright, clear roof with much better light transmission — often noticeably brighter inside.

How often should I have my conservatory cleaned?

We recommend annual cleaning to prevent algae buildup and maintain light levels. Properties in Hampshire with overhanging trees — common in areas like Farnborough, Fleet and Alton — may benefit from twice-yearly cleaning.

Will conservatory cleaning damage my UPVC frames or seals?

No. We use gentle, non-abrasive methods specifically suited to UPVC and rubber seals. Our cleaning solutions are pH-balanced and safe for all conservatory materials. We also inspect your seals during the service and flag any that need attention.

Do you clean inside the conservatory too?

Our standard service covers the exterior roof, frames, gutters and outside glass. Interior glass cleaning can be added to your booking — just mention it when you enquire and we'll include it in your quote.
