If you live in the Adelaide Hills - Stirling, Aldgate, Bridgewater, Crafers, Mylor, Heathfield - bushfire gutter preparation is the most important annual maintenance task on your home. The CFS spells out the requirement.
The CFS Bushfire Survival Plan
The South Australian Country Fire Service publishes the Bushfire Survival Plan template with 5 preparation steps. Step 3 is:
Clean leaves and debris from your gutters regularly, especially before and during the fire danger season. Embers can land in dry leaf litter in gutters and start fires on or in your home.
The 1 November deadline
The SA Fire Danger Season runs from 1 November to 30 April typically for the Mount Lofty Ranges and Adelaide Metropolitan districts. Gutters should be cleaned before that date - the CFS is explicit on this.
BAL ratings and what they mean
BAL (Bushfire Attack Level) ratings under AS3959-2018 classify properties by bushfire exposure:
- BAL-12.5: Low exposure. Ember attack risk. Gutter guards recommended.
- BAL-19: Moderate exposure. Ember attack + radiant heat. Ember mesh strongly recommended.
- BAL-29: High exposure. Ember attack + significant radiant heat. Ember mesh + non-combustible gutter recommended for new build.
- BAL-40: Very high exposure. Ember mesh + non-combustible elements required for new construction.
- BAL-FZ: Flame zone. Full bushfire-rated construction required.
Most Adelaide Hills properties sit BAL-12.5 to BAL-29. Some BAL-40 in denser bushland and ridge-top properties.
Ember mesh gutter guards
For BAL-12.5 and above, aluminium ember mesh (1.8mm aperture) is the AS3959-aligned standard. Brands include Leafshield, Gutter-Vac, Gutter Guard Australia ember mesh range, and several Adelaide installers. Plastic mesh is not bushfire-rated and degrades in UV.
Cost: $45-$80 per metre supplied and installed. For a typical Hills cottage with 60-90m of gutter, total is $2,700-$7,200.
The Hills cleaning schedule
- April-May: post-autumn leaf drop full clean
- October (before 1 November): pre-Fire Danger Season clean
- January-February (optional): mid-summer follow-up where heavy gum fall continues
Some Hills households add a fourth visit after a particularly windy spring.
Insurance implications
Many home insurance policies in bushfire-prone areas now include maintenance conditions. Documented twice-yearly (or three-times-yearly) cleaning with photo evidence is becoming a de facto policy requirement. Keep the invoices and photos.
What our network does
Cleaners matched for Hills postcodes are familiar with CFS Bushfire Survival Plan requirements, BAL ratings, and ember mesh installation. We flag Hills properties at the matching stage so you only get quotes from bushfire-aware contractors.
