Quick Cleaning Enquiry

Passionate about providing the very best quality window cleaning services across Greater London and West Hertfordshire, including Watford, Stanmore, Rickmansworth, Denham, and Bushey.

  • Trained, uniformed, insured, and fully equipped staff.
  • During the day, or out of hours – whenever suits! Our team will be flexible around your needs, providing daily, weekly, or one-off services as required.
  • We are SafeContractor accredited, meaning you can trust us to provide rigorous standards of health and safety at all times.

It’s where we started. The Callver Cleaning Co started in Watford in April 2005, offering domestic carpet cleaning services to private people in the Watford area. We’ve grown substantially since then but we’re still very proud to offer a carpet cleaning service to domestic customers, as well as commercial premises, offices, schools, communal stairwells, and hotels.The service is available either on its own or in conjunction with a Spring Clean or Tenancy Clean.

Our professional carpet cleaners have expert knowledge in stain and spot removal, the ability to deal with high traffic areas and specialist knowledge to remove specific marks such as blood, paint, bodily fluid and beverage stains. 

We only use the best materials and equipment, the majority of which is sourced from Prochem, Europe’s leading carpet cleaning product supplier. 

We’re based in Watford which makes us perfectly situated to help everyone throughout Hertfordshire and London as well as those in our own town.

Thank you Jess, it was brilliant.
