At RJ Custom Joinery we blend unmatched craftsmanship with cutting‑edge high‑end timber windows and doors to give your home a timeless, sustainable connection to the outdoors.

Custom Bespoke Timber Windows & Doors

We specialise in custom timber windows and doors that are handcrafted to your exact specifications. By merging traditional joinery techniques with modern design principles, we deliver a perfect balance of durability, functionality, and style.

Energy‑Efficient & Sustainable Solutions

Our energy‑efficient timber frames meet rigorous bush‑fire ratings and high wind‑load standards, making them ideal for coastal and fire‑prone regions. Paired with responsibly sourced timber, they create a regenerative solution that minimises environmental impact.

Tailored Design for Every Space

Whether it’s a timber servery window for the kitchen or an entertainer’s door with integrated screens, we design each opening to suit the room’s orientation, natural light, and ventilation needs. Imagine a panoramic timber garden window that beautifully frames your landscape, or a timber bathroom window that provides superior ventilation and privacy while effortlessly whisking away steam.

Performance‑Driven Features

Each of our windows and doors is meticulously engineered to deliver:

• Low U‑values for superior thermal efficiency

• High‑performance double glazing that maximises insulation and reduces heat loss

• Acoustic optimisation to keep unwanted noise out while preserving indoor tranquillity

• Thoughtful functionality tailored to everyday living

We also consider critical site‑specific factors:

• Room location & directional exposure – ensuring optimal solar gain and shading

• Breathability – allowing fresh airflow without compromising energy performance

• Integrated bug screening – keeping insects out while maintaining ventilation

The result is a product line that not only meets stringent energy standards but also “breathes” harmoniously with your home’s unique environment.

Renovation & Replacement Expertise

When older frames become outdated or under‑performing, our custom timber door and timber window replacement options give you a premium upgrade. While a high‑end timber window carries a higher upfront cost, its superior sealing and insulation deliver long‑term savings on heating and cooling.
