Doors and windows contribute significantly to building security and protection from the elements. Defective frames and hardware can impact the performance of a property and can cause deterioration of other building elements.

We are mindful of the condition of the existing components and the nature of the defects and take a practical approach to restoring their functionality. We are able to provide repair and maintenance services for doors and windows, as well as replace faulty hardware components. We also provide planned preventative door and window maintenance for commercial buildings. We would welcome the opportunity to speak with you regarding your requirements.

Our Door and Window Specialisations
There are variations in door and window requirements for homes, units, commercial buildings and other shared buildings. Our services can be adapted for the particular needs of the property, use of the building and state of the components.
Residential Door Repairs and Installation
Residential doors need to provide security and be in regular use. Damaged and worn door components can restrict operation of the door and may need to be replaced or repaired. The appropriate solution depends on the door's construction, the condition of its frame and hardware, and any specific security or fire-safety requirements that apply.

- Internal door repairs and replacement
- Door hardware repair and replacement
- Hinge and alignment adjustments
- Door installation for selected renovation or replacement projects
- Maintenance of accessible door components
Commercial Door Repairs and Maintenance
Doors that provide access or security to the commercial premises can be critical to the daily business operations. Door frames or hardware failing can result in irritating and occasionally embarrassing situations and should be corrected as they occur. For commercial premises, the intended function of each door should be considered when developing the building maintenance plan. Repairs and replacement of doors that form part of a regulated assembly should be done by a qualified person to ensure the performance of the door assembly is not compromised.

- Inspection of accessible hinges, handles and locks
- Adjustment of doors that stick or do not align correctly
- Replacement of unsuitable or deteriorated hardware
- Maintenance of office, retail and shared-area doors
- Assessment of door replacement requirements
Window Repairs, Replacement and Commercial Window Maintenance
Apart from the aesthetics of a building, well-maintained windows enhance the functioning of the building by providing adequate ventilation and natural lighting. Seals around the window frames should be intact to prevent water and air from passing through. If a window failure has resulted in water penetration and subsequent deterioration of the building facade or surrounding materials, this may require further investigation. Replacement of the window component may not remedy the problem if the building elements adjacent to the window are also deteriorated.
- Assessment of damaged window components
- Repair or replacement of suitable hardware
- Inspection of accessible frames and fittings
- Investigation of difficult-to-operate windows
- Window replacement where repairs are unsuitable
- Maintenance recommendations for shared and commercial facilities
Door and Window Replacement and Urgent Repairs
The minor repair of doors and windows may be necessary to address an operating problem. However, there are some problems for which replacement may be more appropriate. This may be the case if the door or window components are severely deteriorated or damaged, or the door or window is badly operated or unsuitable for the application. Emergency door repairs or emergency window repairs may also be necessary when damage affects access, security or protection from the weather. The immediate response depends on the nature of the damage, the risks involved and service availability. If a broken window or damaged door presents an immediate safety hazard, keep people away from the affected area and arrange suitable assistance. Any temporary securing measures should be appropriate to the situation and should not compromise required fire exits or building safety provisions.

- Recommendations for repair or replacement
