Door and Window Replacement for Apartment Balconies – Northern Beaches Experts

Replacing old or damaged balcony doors and windows is one of the most important — and often overlooked — steps in upgrading multi-residential buildings. On the Northern Beaches of Sydney, coastal exposure, aging materials, and poor original installation can lead to leaks, corrosion, draughts, and even structural concerns.

At Plan A Builders, we specialise in door and window replacement for multi-unit apartments and strata buildings, particularly where balconies are substandard or being upgraded. Whether you're dealing with leaky sliding doors, rotted window frames, or non-compliant access points, we provide expert, code-compliant replacements built for durability and performance.

🪟 Why Replacing Balcony Doors and Windows Matters

Older balcony windows and doors often suffer from:

• Timber frame rot due to water ingress

• Corrosion of aluminium components from salt air

• Failing seals and glass units that let in moisture

• Poor energy performance and noise insulation

• Non-compliance with current NCC/BCA standards

For many Northern Beaches apartments, these elements were never built to last in a harsh coastal environment. As balconies are upgraded or made compliant, door and window replacement is often required to ensure watertightness, energy efficiency, and safe access.

🔨 Our Door & Window Replacement Services Include:

• Removal of old doors, frames, and windows

• Custom replacement of sliding or hinged balcony doors

• New aluminium or uPVC framed window installations

• Double glazing upgrades for energy and noise control

• Sealing and flashing to prevent future water ingress

• Compliance with Australian Standards and NCC requirements

We work with trusted suppliers to source high-quality, corrosion-resistant products suitable for strata buildings near the coast.

🏙️ Focused on Multi-Residential & Strata Buildings

We’re not a retail window company. We’re licensed builders who work with:

• Strata Committees

• Building Managers

• Engineers & Certifiers

If you're undertaking balcony remedial works, waterproofing upgrades, or façade improvements, we integrate door and window replacement into your project plan — with all work documented and compliant with council and strata requirements.
