Replacing a Garage Door on an Older Adelaide Home

Older Adelaide homes — typically 1950s-1990s builds — often carry their original or first-replacement garage doors. By the time we get a call, the door is 25-50 years old, the springs are tired, the panels are tired, and the homeowner has been living with a slow, noisy door for a few years too many.

Here’s how the replacement project actually unfolds.

What’s typically there now

Three common door types we see in older Adelaide homes:

1. One-piece tilt door (1950s-1980s)

Single-panel timber or steel door that tilts outward and up, on side springs. Most common in 1970s-1980s builds across Modbury, Salisbury, Reynella, Plympton.

State at year 30+: timber rot at bottom rail; rusted steel panel; tired side springs; pivot points wearing out of the door frame; manual operation common.

2. Single-skin steel roller door (1980s-1990s)

Corrugated steel coil door, motorised. Common in 1980s-1990s suburban builds.

State at year 25+: coil corrosion (especially coastal); spring fatigue; motor on its last legs; bottom slat damage from vehicles; manual lock seized.

3. Early sectional door (1990s)

Sectional panel doors became common in newer builds from the mid-1990s. Less commonly seen at end-of-life unless the home is in the older newer-suburb belt.

State at year 25+: panel rust at bottom; hinge wear; original motor failed; safety beam/sensors out-of-date with current standards.

What you’re typically replacing

The replacement project usually covers:

1. The old door itself — removed, disposed of (concrete-and-steel weight; typical removal $80-$220).
2. The tracks — replaced wholesale because alignment, age, and corrosion mean re-use is rarely sensible.
3. The springs — new torsion or extension springs to match the new door.
4. The motor — almost always replaced. Old motors are often EOL and incompatible with modern remote/safety standards.
5. The remotes and keypad — new, paired to new motor.
6. The bottom and side weatherseals — new.
7. Sometimes the structural opening — older openings may be slightly out of square, needing minor framing adjustment.

What can surprise you

The opening is out of square

Older Adelaide homes often have garage openings that have settled 5-15mm out of square over the decades. A new sectional door needs a square opening; minor framing adjustment or compensating shimming is sometimes needed. Usually $200-$500 added cost.

The header is timber and tired

Timber lintels above the opening (common in 1960s-1970s builds) sometimes have spring-bracket bolts pulling out under load. New brackets need fresh fixing; sometimes a steel reinforcement plate goes in.

The wiring is original

Old garages often have a single power point at the back of the garage — fine for a 1980s motor, marginal for a modern smart opener that may need network connectivity. An electrician visit is sometimes needed for power and data ($250-$600).

Asbestos in older garage walls

Pre-1990 builds occasionally have asbestos-cement sheet walls. If the install needs to drill or fix into the wall, asbestos identification and licensed removal procedures kick in ($500-$2,000+ depending on extent).

A reputable installer will flag this on the measure.

The door is wider/taller than current standard

Older builds sometimes have non-standard openings (2,250mm wide, 2,200mm tall — close to but not matching current 2,400mm standards). Custom-size doors are 4-6 weeks lead time vs 1-3 weeks for stock sizes.

Heritage and council considerations

For genuinely heritage homes (pre-1940 in some Adelaide council areas), planning consent may apply for any front-of-house change. Your installer should check local council heritage zones before quoting. This can add 4-8 weeks to the project.

Cost ranges for older-home replacements

Scenario	Typical range
Tilt → roller, single, builder-spec	$1,800-$2,800
Tilt → sectional, single, R3 insulated	$3,400-$4,800
Tilt → custom timber sectional (heritage match)	$5,800-$11,000
Single-skin roller → R3 sectional	$3,200-$4,800
Original sectional → modern smart sectional	$3,400-$5,200

These ranges include door, motor, install, removal, basic commissioning. Add for surprises (framing, wiring, heritage consent, asbestos).
