Issue |
Defect Cause |
Defect Remedy |
Insufficient roof ventilation |
- Modern airtight building methods trapping moisture
- Inadequate provision of ventilation in original design
- Blocked or covered vents during later modifications
|
- Installation of additional roof vents
- Creation of proper airflow paths
- Ensuring insulation doesn't block eaves ventilation
|
Poorly fitted door frames |
- Rapid construction methods affecting quality
- Settlement of new buildings
- Materials movement with temperature and humidity changes
|
- Adjustment and reseating of frames
- Replacement of inadequate fixings
- Complete replacement in severe cases
|
Jammed or ill-fitting windows |
- Settlement in new builds affecting frame alignment
- Poor quality fitting during construction
- Materials movement with seasonal changes
|
- Adjustment of hinges and mechanisms
- Easing of frames where binding occurs
- Possible replacement of severely affected units
|
Poor ventilation leading to condensation |
- Airtight building design without adequate ventilation
- Residents blocking vents to prevent draughts
- Inadequate extraction in kitchens and bathrooms
|
- Installation of improved extraction systems
- Addition of passive vents or trickle ventilators
- Education on managing household humidity
|
Settlement in new builds |
- Natural settling of foundations in early years
- Poor ground preparation before construction
- Variations in soil conditions
|
- Monitoring of cracks to determine if active
- Repair of cosmetic damage after settlement completes
- Structural repairs if settlement is excessive
