Hay Stone operates a small sandstone quarry in the Black Mountains of England & Wales, from where we hand source and process naturally-riven sheets of grey sandstone. From these we can manufacture bespoke stone hearthstones to virtually any size (within certain natural limits) and shape you require.We specialize in manufacturing large t-shaped hearthstones to fit into existing fireplaces. Front and side edges are hand-dressed to create a rustic appearance and to remove sharp edges. Our hearthstones are sealed with a specialist product to protect against stains and scratches. Feel free to call our helpline number 07773 778118 for further assistance.
