Slate window cills

Lasting a lifetime

Slate offers a high end finish to any room and will not expand, contract or become mouldy - all problems associated with natural or engineered timber products.

Internal cills are virtually maintenance free (dusting apart) they are an attractive and practical addition to any property. All cills are bespoke and are produced to your measurements. Various thicknesses are available, the standard being 30mm.

External cills have all the advantages of internal cills, and as they are totally unaffected by weather, they will literally last a lifetime. 

Below are some examples of our work, please feel free to contact us for more information.


We can produce any shape and any size to your specification.
