We have proudly retained the Dulwich Picture Gallery as one of our very first clients almost 20 years ago.  

 Today, GSS provides high quality professional cleaning services to art galleries, museums and theatres.  

We offer clients full flexibility on cleaning hours and times – ensuring that venues remain spotless during busy exhibition and show runs.  

We additionally offer regular scheduled deep cleans and if necessary a Covid-19 specialist disinfectant fogging service.
