Renovation Glass Clean of Palm House – Kew Gardens


The Grade I listed Palm House at Kew Gardens had very low light transmission to the specimens due to years of biological growth on the glass.  

To improve the visitor experience and help plants to thrive, it was necessary to formulate a sympathetic cleaning plan.


Working closely with the conservation team, site stakeholders and FM main contractors; we devised a schedule of works to renovate the interior and exterior glazing.

A multi-disciplinary approach was required with abseilers, MEWP operators and Reach&Wash specialists on site. 

Work Summary 

The cleaning of the conservatory took over two months, working in restricted hours to achieve an invisible service delivery. 

With much media attention from newspapers and the BBC, this was a high profile clean working safely around visitors and staff.
