All our Douglas Fir logs come from managed plantations certified by the Forestry Stewardship Council (FSC). Once the logs have been delivered to the yard and had their bark removed, they will be treated with Anti-Sapstain spray (Copper-8, EPA-registered, water-based, FDA-approved for food contact) and Baimol anti-mould fungicides, to prevent mould, insects, and blue stain. Whilst logs remain in the yard, during the construction of a handcrafted log home, they will be periodically treated again to keep them in top shape. After the log shell is completed it will be given a final clean and treatment (if needed) then when dry will get a first coat of stain.
