Duchy Timber

At Duchy Timber, Cornwall's largest sawmill, we use timber sourced from local woodlands to produce premium quality Tanalised® timber for joinery, fencing, landscaping, decking and agricultural use. We are accredited by the Forestry Standards Council (FSC) and the Programme for the Endorsement of Forest Certification (PEFC) which ensures the timber we buy is from sustainable, managed woodland. We use mainly Douglas fir, Larch and Spruce felled within 100 miles of the sawmill. Timber is kiln-dried before our ISO9001 accredited treatment is administered to ensure optimum uptake of the preservative.


We also machine and treat structural timber for the construction industry. We offer a bespoke moulding service to match any profiles of skirting and architraves up to 180mm; a service especially useful for those involved with renovations.

Our skilled team in the Carpenters Shop manufacture a range of quality gates, garden sheds, garden furniture, fence panels and trellis. We can also make the majority of our products to your bespoke design and specification.
