Cleaning the Outside of Your Greenhouse or Conservatory

Greenhouse and conservatory glass accumulates algae, lichen, and mineral deposits over time, significantly reducing the amount of light transmitted. For a greenhouse, this reduction in light affects plant growth; for a conservatory, it makes the room darker and less pleasant. Professional cleaning of glass panels and frames restores light transmission and dramatically improves appearance.

The external frames of greenhouses and conservatories — whether aluminium, uPVC, or timber — also accumulate algae and grime. These are cleaned using appropriate low pressure and specialist UPVC or metal cleaners as appropriate. Care is taken around sealing strips, opening mechanisms, and any vulnerable areas.

Conservatories attached to houses should be cleaned carefully to avoid forcing water into the joint between the conservatory roof and the house wall. This junction is a common area for water ingress if not properly sealed, and high-pressure washing can make any existing vulnerability worse. A careful, low-pressure approach with attention to the roof-wall junction is the right method.
