Garage doors in Cranbourne.

Two distinct property types.

The growth-corridor estates (Cranbourne East, West, North, Park — Eliston, Avena, Brompton, The Avenue, Aspire, Riverdale and similar releases) are double-storey homes on 350–500m² blocks with double garages and a bedroom or home office directly above. The most common job here is a same-day spring repair on an 8–14 year-old builder-grade door, often paired with a quiet belt-drive motor upgrade because the original chain-drive is waking the upstairs bedrooms.

Established Cranbourne (around the township, along South Gippsland Highway, Stawell Street, Berwick-Cranbourne Road) has plenty of 1980s–2000s single-garage brick veneer homes with tilt doors or first-generation sectionals on the way out. These are usually full-replacement jobs — new insulated sectional with a smart belt-drive opener, ~$2.5K–$5K supplied and installed.

Class M reactive-clay slab movement.

Cranbourne sits on Class M reactive clay. Garage slabs shift 5–15mm seasonally on most blocks — over 10 years that adds up to noticeable track misalignment. Symptoms: door binding on one side, rubber bottom-seal not touching the slab, opener struggling at the same point of the lift each cycle. A 45-minute re-track-alignment ($180–$280) usually fixes it for another 5–7 years.
