About Us

Calders & Grandidge is one of the oldest and most respected names in the UK pressure treated timber sector. From our 46 acre site in Boston, Lincolnshire we have over 100 years experience supplying the finest quality fencing, gates, sleepers and garden products to the UK.

We have been the proud holders of the Royal Warrant for the supply of preserved timber fencing to Her Majesty The Queen for many years now, and our products can be found in situ at The Royal Stud.

All the timber we use in the construction of our products in FSC/PEFC compliant, meaning we only source timber from well managed, sustainable forests to limit our environmental impact as much as possible.
