Windows do more than bring in light and fresh air—they shape how we use and care for our homes. Whether you’re a homeowner trying to diagnose a drafty window or a strata manager overseeing a complex with ageing infrastructure, it helps to know exactly what kind of windows you’re dealing with.
This guide breaks down the most common window types found in Australian properties, explains how they work, and flags the signs that something’s gone wrong. From sliding to louvre, we’ll help you identify your windows—and understand when it’s time to call in the pros.
Why Window Type Matters
Each window type opens and seals in its own way, which means its weak points, maintenance needs, and repair solutions are also unique. Misidentifying your window can lead to unnecessary costs, incorrect DIY attempts, or long-term energy loss. That’s why Lock & Roll offers tailored window repair services that match the function and structure of each type.
1. Sliding Windows
How they work: Sliding windows move horizontally on a track, much like a patio door. They’re simple, common, and often found in post-70s suburban builds.
Typical failure points:
- Broken or seized rollers
- Worn track or debris build-up
- Window won’t stay closed or locked
Ease of maintenance: Easy to clean and operate, but rollers can wear out quickly in older builds.
When to call us: If your sliding window feels stiff or you hear grinding sounds, you may need a track clean or a roller replacement.
2. Double-Hung Windows
How they work: Both the top and bottom panels (sashes) can move up and down. Common in older terraces and period homes, these windows rely on spring balances or counterweights.
Typical failure points:
- Stuck sashes due to paint or frame swelling
- Broken spring balances
- Difficulty locking or staying open
Ease of maintenance: Moderate. Cleaning between the sashes can be tricky, and older cords or springs often fail.
When to call us: If one panel slams shut or won’t stay up, the balance system has likely failed.
3. Awning Windows
How they work: Hinged at the top, awning windows open outwards from the bottom using a chain winder. Popular in brick veneer homes and apartment blocks.
Typical failure points:
- Stiff or jammed chain winders
- Worn or broken stays
- Leaks around the frame in storms
Ease of maintenance: Relatively easy. Chain winders require occasional lubrication.
When to call us: If the window resists opening or doesn’t seal fully when shut, it may need new hardware or alignment.
4. Casement Windows
How they work: Side-hinged and crank outwards, much like a door. Found in many mid-century and federation homes.
Typical failure points:
- Broken latches or hinges
- Wind damage if left open
- Frame misalignment over time
Ease of maintenance: High airflow makes them great for ventilation but also prone to wear from movement and weather.
When to call us: If your window bangs in the wind or the latch no longer holds tight, it’s time for service.
5. Louvre Windows
How they work: Operated by a lever, multiple horizontal glass blades tilt open and shut in unison. Common in bathrooms and coastal homes.
Typical failure points:
- Corroded control arms
- Blades not closing flush
- Air leaks and poor thermal seal
Ease of maintenance: Easy to clean blade-by-blade, but mechanisms can corrode in salty or humid areas.
When to call us: If the blades don’t shut fully or rattle in the wind, you may need a full mechanism replacement.
6. Fixed-Pane Windows
How they work: As the name suggests, these windows don’t open. They’re purely for light or views, often seen in stairwells or architectural features.
Typical failure points:
- Frame leaks or seal failures
- Foggy appearance from moisture in double glazing
Ease of maintenance: Low. No moving parts, but problems with the seal or frame often require professional resealing.
When to call us: If you see condensation inside a sealed unit or feel drafts from a fixed pane, the glazing seal may have failed.
Signs You Need a Repair—No Matter the Type
Even the best-built windows show signs of age. Watch for these red flags:
- Stiff or jammed windows that resist opening or closing
- Broken or seized handles, latches, or hinges
- Windows that won’t close or lock, posing safety risks
- Grinding, squeaking, or rattling noises during use
- Frames scraping walls or sills, often from misalignment
- Windows that won’t stay on track—common with sliding types
- Visible moisture or fog between panes of glass
Whether it’s a broken hinge, faulty closer, or simply a window that won’t stay open, Lock & Roll offers fast and reliable window repairs across all styles.
