Q

3 most common resi defects

A
  1. Movement/settlement - caused by subsidence, heave (ground expansion) and ground movement. Causes cracking
  2. Damp - wet rot vs dry rot, rising damp (to 1.5m), condensation, leaks
  3. Defecting materials

Q

Dry vs wet rot

A

Both attack timber

Dry =

Needs 15% moisture. Worse than wet. Identified by brown timber. fungal attack, causing mushroom like fungus, red spores, strong smell and can cause timber to crack. If left untreated the timber will crumble. Can spread through plaster and neighbouring walls. Can cause structural issues

Wet rot =

Needs 25% moisture. damp and timber decay due to damp. Can cause fungal attack.
