We do not pre-drill beams, as fixing positions must align precisely with your wall structure.

Customers should ensure compliance with relevant fire-safety and building regulations before installation.

If you are unsure which beam style (Contemporary, Lightly Worked or Heavily Worked) best suits your home, we recommend watching our guidance video:

Our character grade beams may contain natural splits and checks which can continue to develop as the timber acclimatises.

Although air-dried, oak may continue to shrink slightly as it adjusts to your property's temperature and humidity.

If installing above a fire or log burner, we recommend gradually increasing heat exposure over the first week.

These characteristics are not faults — they are part of the beauty of real solid oak.
