The Trusted Lime Experts

Our Mission

We passionately believe that using the correct breathable materials is crucial for the appropriate care and repair of our built heritage.
Whilst we won’t claim that lime solves all issues when it comes to the conservation and restoration of older buildings, we still believe that it is undisputably the best material available to manage the whole phenomenon of moisture in solid wall construction.

We manufacture a range of products on-site in Cornwall, including Lime Putty, Putty Based Mortars and under the Cornerstone brand, our range of Drymix Mortars and Renders. We work with a number of like minded manufacturers such as St. Astier and Beeck to supply an extensive range of breathable building materials.

Product Categories

With a reputable trade background in the care and repair of old buildings and a 25 year pedigree, Cornish Lime are the largest manufacturer and supplier of Lime products in the country.
