Rock and co is based in Hertford, Hertfordshire. We are manufacturers and suppliers of Luxury Granite and Quartz Kitchen Worktops to both Domestic and Commercial customers. Founded in 2007 we have grown at a substantial pace through the economical struggles, owing to the Quality and Service we deliver day in-day out. We have invested over £1m in machinery and equipment ensuring we continue to push forward and meet the demand for our amazing products. Rock and Co boasts a factory of the latest state of the art Cad Cam, CNC precision machinery and Laser Templating tech which not only allows us to work from Architectural drawings (including DXF or traditionally where required) but is very fast and accurate to 1/10th of a millimetre, ensuring perfect fitting every time. We source our quality products directly from a select panel of manufacturers, producing a comprehensive variety to suit all tastes and requirements. These are readily available to be viewed at our in store showroom in Hertford. We have just completed (March 16) a manufacture, supply and fitting of 180 worktops project with Western Homes successfully and are currently working on a project with Higgins Group. Our valued team of people, including an array of industry experts, from the tea maker to the MD all working together for a common outcome is why Rock and co is such a great, innovative company to work for and to work with.
