The Callver Cleaning Co was born in 2005 in Watford, Hertfordshire. The company name was created from the names of two special boys, Callum and Oliver, our owner’s godson and nephew. The company, and everything we stand for, is dedicated to them.

The company started because we ourselves couldn’t find a high quality, reliable and affordable cleaning service. We tried to many but were so often let down or left disappointed.

We started by offering a regular domestic cleaning service to local people in and around Watford, and the business took off very quickly from there, with requests to help local offices, schools, and apartment buildings.

We now offer a variety of cleaning services throughout Watford and Hertfordshire, as well as across Greater London, Essex, and Buckinghamshire. We look after a variety of offices, local and national house builders, those in need of tenancy cleaning, as well as over 40 residential developments, taking care of their shared entrances, hallways, lifts and bin stores.

Our fully trained, uniformed, and insured staff have a fleet of vehicles, all of which are sign-written, stocked, and fully equipped to tackle whatever the day brings.

We hope we can help you with your cleaning requirements, so please get in touch to discuss anything; we’re here to help.

Callver is committed to providing the best, most trusted cleaning service possible, using the very best staff around, with the best materials available at a reasonable and fair price... It’s as simple as that.
