Secure Strata Window & Door Installation in Sydney
Strata window and door installation in Sydney requires more than replacement work. It demands compliance, structured coordination, and clear documentation. At ATCO Projects, we manage strata window replacement and strata door upgrades with a governance-led approach that prioritises safety, building performance, and minimal disruption to residents.
From ageing aluminium frames to non-compliant fire doors, we deliver installation solutions aligned with NSW building standards and strata committee requirements.

Why Windows & Doors Fail in Strata Buildings
Strata buildings across Sydney experience recurring window and door failures due to environmental exposure, ageing materials, and outdated installation standards.
Common causes include:
- Water ingress from deteriorated seals
- Corrosion in aluminium or steel frames
- Timber rot in older window systems
- Failed balcony sliding doors
- Non-compliant fire-rated entry doors
- Poor acoustic insulation between units
- Drafts and rising energy costs
In many cases, window replacement in strata buildings becomes necessary after engineering reports, insurance reviews, or committee budget allocations. Early identification and planned upgrades reduce long-term structural risk and liability exposure.
Our Window and Door Installation Process
A structured process ensures compliance, cost control, and clear communication with strata managers and committees.
1. Inspection & Compliance Review
A structured process ensures compliance, cost control, and clear communication with strata managers and committees.
2. Scope of Works & Committee Approval
We prepare a documented scope including:
- Product specifications
- Glazing options (including double glazing for strata)
- Access staging plans
- Installation sequencing
- Budget breakdown
This documentation supports committee approvals and ensures alignment with owners corporation requirements.
3. Removal & Installation
Existing windows or doors are removed in a controlled manner to prevent damage to surrounding finishes. Installation includes:
- Compliant aluminium or timber systems
- Sliding balcony doors
- Fire-rated door replacements
- Energy-efficient glazing upgrades
All work is staged to reduce disruption to residents and common areas.
4. Testing, Certification & Handover
Upon completion, each system is tested for:
- Smooth operation
- Weather-tightness
- Locking function
- Compliance with relevant standards
A documentation pack is provided for strata records and insurers. This structured close-out process reduces future disputes and ensures accountability.
Scope of Our Window Installation Services
For strata property owners, upgrading to double glazed windows can significantly improve energy efficiency, reduce noise, and enhance comfort. However, as windows and doors are typically considered common property, any replacements or upgrades—including the installation of double glazing—require approval from the owners corporation or body corporate. Special approval may also be necessary for heritage buildings to ensure compliance with legal and aesthetic requirements.
Full Window Replacement
Suitable for buildings with aged, damaged, or inconsistent windows.
Features include:
- Choice of single, double, or triple glazing
- Aluminium, timber, or composite frame options
- Improved insulation and durability
- New double glazed windows improve energy efficiency by minimizing heat transfer
- A unified look across the building, with careful attention to painting and matching style to ensure replacements look identical to the original
Our team helps committees select windows that match the property’s character and meet regulatory standards.
Glazing and Sealing
Buildings lose substantial heat through poorly sealed windows. Our glazing and sealing solutions help maintain a comfortable internal environment and reduce noise transfer. Double glazing significantly reduces noise pollution in strata properties, creating a quiet and comfortable environment for residents. Installing double glazing also helps maintain consistent, comfortable temperatures year-round and can enhance indoor air quality by preventing moisture build-up.
We use high-quality sealants and modern glazing systems designed for long service life.
Security and Fire Compliance
Some strata buildings require upgraded fire-rated glass, restricted opening hardware, or added security measures. We offer:
- Fire-rated window solutions (including compliant front doors and hinges, which are critical for maintaining fire safety and security)
- Security screens or bars (where appropriate)
- Hardware compliant with current building regulations
Fire doors, including front doors to individual units and doors leading to public areas, are specifically designed to compartmentalize fire and smoke and must meet strict Australian standards.
Scope of Our Door Installation Services
Doors play a large role in safety, access, and overall building performance. Strata doors refer to the various common property and lot-specific doors within a strata-titled property, such as main entrance, fire, balcony, and individual unit doors. We support strata buildings with a wide range of door types.
Unit Entry Doors
Entry doors need to meet strict standards for durability, fire resistance, and security. We install:
- Solid-core fire-rated doors (front doors to individual units and doors leading to public areas are generally required to be fire-rated and certified to Australian standards, such as AS1905)
- High-performance locking systems
- Designs that complement building aesthetics
In Australia, front entry doors in strata schemes must comply with fire safety standards and building codes. Any modifications to a front door require prior consent from the owners corporation to ensure compliance.
Our team works with committees to choose consistent, compliant options for all units.
Common Area and Access Doors
Shared spaces need doors that can withstand frequent use. In strata properties, common area and access doors—such as main building entry doors, fire doors, and usually the external doors and windows of individual units—are considered common property. These are maintained and repaired by the body corporate or owners corporation, which is also responsible for ensuring regular inspections of fire doors as required by regulations.
We install doors for:
- Hallways
- Stairwells
- Plant rooms
- Storage areas
Each door is fitted with compliant hardware for safe access and reliable performance.
Sliding and Balcony Doors
Suitable for apartments with outdoor spaces. Options include:
- Aluminium sliding doors (a stylish and practical choice for both homeowners and builders)
- Double doors for added elegance and charm, blending classic looks with modern benefits
- Glass panels for improved natural light
- Timber frames for select architectural styles
These options allow you to choose doors and windows that complement your building’s overall style and add a touch of charm. These installations help improve ventilation, visibility, and access to outdoor areas.
