Jeff Williams Mobile Pressure Washing was started in 2003 by Jeff Williams with one main aim, which was to provide a first class cleaning service, which all of his customers could depend, rely on, and be more than happy to refer to new customers. Since we started we have grown from strength to strength and from our base in Devon we service clients all over the UK 24 Hours a day. We are pleased to have recently renewed our SMAS Worksafe certificate. This means that we have met the SSIP core criteria recognised by the HSE and other SSIP accreditation schemes.
