Overview
Replacement is right when: slab damage compromises the timber core; frame is beyond re-fixing; U-value is dated (pre-2010); security spec is unfixable; aesthetics are past restoration; or repair cost exceeds 60% of replacement.

- Water damage into the timber core.
- Cracked or crushed slab.
- Frame beyond re-fixing.
- Pre-2010 U-values.
- Persistent security failures.
Common causes
