Why is my timber cladding coming away from the wall?

There are several factors which could result in timber cladding disengaging itself and/or coming away from its supporting structure.

The most common culprits are:

  1. the board is not designed to withstand external environments (has too small a tongue and/or board is too wide and can't accommodate seasonal movement);
  2. bad installation - no movement gaps incorporated;
  3. incorrect fixings and/or fixing placement. 

Points 1 & 2: read our blog which explains why size, species and movement matter when it comes to external board profiles.

Point 3: read more about cladding fixings
