Many original homes in Merrylands, Guildford, Granville and Auburn contain asbestos. This guide covers identification, removal costs, regulations, and safe demolition practices.
Asbestos in Cumberland LGA Homes: Identification and Risk Assessment
A significant proportion of homes across Cumberland LGA suburbs — including Merrylands, Guildford, Granville, Auburn, South Granville, Berala, Regents Park, Greystanes, and Wentworthville — were built between the 1940s and mid-1980s using asbestos-containing materials (ACMs). Asbestos was widely used in Australian residential construction until it was progressively banned, with a total ban taking effect in 2003.
Common asbestos-containing materials in Cumberland LGA homes:
• Fibro sheeting (flat and corrugated): Widely used for wall cladding, eaves, and internal linings in homes built 1940s-1980s. This is the most common ACM in Cumberland homes. • Floor tiles (vinyl): Some vinyl floor tiles manufactured before 1980 contain asbestos fibres in the tile or the adhesive/backing. • Bathroom and kitchen sheeting: Wet area linings behind tiles were often asbestos cement sheet. • Roof sheeting: Corrugated asbestos cement (Super Six) roofing was used extensively. • Fencing: Asbestos cement sheet fencing (flat panels between timber posts) is extremely common in Cumberland LGA backyard fencing. • Pipe lagging and insulation: Older homes may have asbestos insulation around hot water pipes and in ceiling spaces. • Textured coatings: Some decorative textured wall and ceiling coatings contained asbestos.
Asbestos risk levels: • Bonded (non-friable) asbestos: Asbestos fibres are bound within a cement or resin matrix. When intact and undisturbed, bonded asbestos presents low risk. However, when cut, drilled, broken, or weathered, it can release dangerous fibres. • Friable asbestos: Asbestos that can be crumbled or reduced to powder by hand pressure. Found in pipe lagging, sprayed insulation, and some ceiling coatings. Friable asbestos is high-risk and requires specialist removal.
Before any knockdown rebuild or renovation in Cumberland LGA, an asbestos assessment should be conducted by a licensed assessor. Buildana includes asbestos assessment as a standard part of every knockdown rebuild project. Visit /homes/knockdown-rebuilds for our complete KDR approach.
Licensed Asbestos Removal: Process, Costs, and Compliance
Asbestos removal in NSW is strictly regulated under the Work Health and Safety Regulation 2017 and associated Codes of Practice. For knockdown rebuild projects in Cumberland LGA, compliance with these regulations is non-negotiable.
Who can remove asbestos? • Licensed asbestos removalist (Class A): Required for friable asbestos removal. These specialists have advanced training, specialised equipment, and air monitoring capabilities. • Licensed asbestos removalist (Class B): Can remove bonded (non-friable) asbestos exceeding 10sqm. Most residential demolitions require at least Class B licensing. • Unlicensed removal: You can remove up to 10sqm of bonded asbestos from your own residential property, but this carries significant health risks and is not recommended.
Asbestos removal costs in Cumberland LGA: • Asbestos survey and assessment: $400-$800 for a standard residential property • Bonded asbestos removal (fibro home, typical): $8,000-$20,000 depending on quantity • Friable asbestos removal (if present): $15,000-$40,000+ depending on extent and access • Air monitoring during removal: $1,500-$3,000 • Asbestos waste disposal fees: $250-$400 per tonne (licensed facility only) • Clearance certificate: $500-$1,000 (required before demolition can proceed)
The asbestos removal process for a Cumberland LGA knockdown rebuild: 1. Pre-demolition asbestos survey: Licensed assessor identifies all ACMs in the building 2. Asbestos removal plan: Documenting scope, methods, and safety measures 3. Notification: SafeWork NSW must be notified at least 5 days before removal of friable asbestos (bonded asbestos removal over 10sqm also requires notification) 4. Site setup: Plastic sheeting enclosure, warning signs, decontamination facilities, HEPA-filtered negative air units (for friable work) 5. Removal: Licensed removalists carefully remove ACMs, double-bag in labelled asbestos bags 6. Air monitoring: Independent hygienist monitors air quality throughout the process 7. Clearance inspection: Licensed assessor confirms all asbestos has been removed 8. Clearance certificate: Issued once the site is confirmed asbestos-free 9. Disposal: All asbestos waste transported to a licensed facility with tracking documentation
Buildana coordinates all asbestos assessment and removal as part of our knockdown rebuild service. Our fixed-price contracts include asbestos management, so there are no unexpected costs for homeowners.
After Asbestos: Demolition and New Construction on Cleared Cumberland Sites
Once asbestos has been safely removed and a clearance certificate issued, the remainder of the demolition and new construction process can proceed. Here is what Cumberland LGA homeowners can expect:
Demolition phase (after asbestos clearance): • Mechanical demolition of remaining structure: 2-3 days for a standard residential home • Removal of slab/footings (if new design requires different foundation system): 1-2 days • Site clearing (vegetation, debris, remnant services): 1-2 days • Waste disposal: All demolition waste sorted and disposed to licensed facilities • Service disconnections: Water, sewer, gas, electrical, and telecommunications disconnected prior to demolition (arranged during the asbestos removal phase) • Total demolition phase: 1-2 weeks including asbestos removal
Site preparation for new construction: • Survey and set-out: Registered surveyor marks building footprint on cleared site • Geotechnical assessment: Soil bore tests confirm soil classification for slab/foundation design • Slab preparation: Depending on soil classification, this may involve: - Stable sites (Class A/S): Standard waffle raft slab - Reactive clay sites (Class M/H1/H2): Engineered waffle raft with deeper beams and more reinforcement - Highly reactive sites (Class E/P): Pier-and-beam system or site-specific engineering solution • Service connections: Temporary construction power, water for construction use
New construction commences: 1. Slab pour: 1-2 days for concrete placement, 7 days minimum curing 2. Frame erection: 2-3 weeks for timber or steel frame 3. Roof installation: 1-2 weeks 4. Lockup: Windows, external doors, external cladding — 4-6 weeks 5. Internal fit-out: Electrical, plumbing, plastering, tiling, joinery — 8-10 weeks 6. Final finishes: Painting, flooring, fixtures, cleaning — 2-3 weeks 7. Landscaping and external: Driveway, fencing, gardens — 1-2 weeks
Total new construction: 8-12 months from slab to handover
