Several different factors go into quoting an insulation project. These include square footage, size of your home, what type of insulation material you require, location etc.
For most projects (usually residential), we should be able to provide a ballpark estimate over the phone. We typically require a site visit to provide a quote for complex projects.
Spray foam is our preferred insulation choice for most projects; however, we may recommend alternatives such as blow-in insulation or insulation batts for some jobs.

Yes. Unfortunately, there's a lot of misinformation online about spray foam safety. Most of this can be chalked up to failed DIY jobs and poor-quality foam and equipment, which can damage your home and risk your safety.

R-value is a unit of measurement that indicates a substance's thermal resistance. Generally speaking, a higher value indicates that the substance is a better insulator, however, a range of other factors come into play, such as if it provides an air-tight seal, thickness etc.
It's important to have your insulation checked once installed. Generally speaking, it's good practice to have your home's insulation assessed every ten years to ensure it's working as it should.
Installing your own insulation is definitely not recommended. By law, you need to have your home first assessed by a Licenced Electrician to ensure your insulation isn't risking overheating of electrical elements and causing a potential house fire. DIY spray foam jobs can also lead to damage to building elements.
Not at all. With every project we complete, your home or workspace will be left clean and mess-free once we finish the job.
Mould often returns when the moisture that fed it is still there. Australian site-audit research records frequent regrowth after remediation when the moisture dynamic was not fixed and materials were not fully dried (EV148). Surface treatment without cutting off the source — plumbing leaks, cladding leaks, or unmanaged water vapour and condensation — leaves the conditions that allow mould to re-establish (EV150, EV477).
Indoor mould is a sign of an underlying moisture problem. The Victorian Building Authority scoping work groups that moisture into three sources: water getting in through defective cladding or roofs, plumbing failure, or condensation from unmanaged water vapour (EV150). Excess moisture supports mould growth and can also promote decay of building materials (EV80, EV83).
Industry consensus recorded in the VBA-VU indoor mould scoping study is that water damage or intrusion should be fully rectified within about 48 hours. Outside that window, members said mould often progressed beyond the surface and was not lastingly resolved without removing and replacing affected materials (EV147, EV476).
Not always. Longitudinal monitoring of Australian homes found mould occurrence did not always line up with long-term indoor air temperatures (EV152). Temperature differences between a conditioned room and an unconditioned space such as a subfloor or cavity can still drive mould risk in wall cavities (EV299). Contractors commonly blame ventilation, but the moisture source may sit below the floor (EV564, EV475).
About 40% of Australian residential buildings are estimated to have problems from condensation alone (ABCB 2016, reported in the VBA-VU scoping study) (EV174, EV515). An Australian integrative review also reported a national concern that up to 40% of homes built since 2003/04 may be at risk of excess condensation leading to indoor or interstitial mould (EV300). Household surveys in the same review found indoor mould reported in 27% of homes, with cracks in walls and floors the most commonly reported problem at 40% (EV293).
Yes, as part of occupancy. The Australian integrative review found highly naturally ventilated homes and highly cleaned homes had a decreased risk of indoor mould (EV303). That does not replace finding and stopping the moisture source in the building fabric (EV148, EV150).
Homes Tasmania’s damp, condensation and mould fact sheet puts typical household vapour loads at about 1 litre from a daily shower, 3 litres from daily cooking, and 5.5 litres from drying clothes (EV400). That indoor vapour still needs a cold surface and a pathway before it becomes condensation (EV82).
Homes with suspended timber floors are susceptible to high indoor humidity from moist subfloor spaces, especially if floor vents are blocked (EV82). Water vapour can move with air through leaks in the floor assembly (EV177). In humid climates the vapour drive during the cooling season is from the crawl space toward the cooler, drier indoors (EV193). Floors above vented and open crawl spaces in hot-humid climates can accumulate moisture that leads to mould, mildew and decay in the floor even when the crawl space meets code (EV168).
Often they do not. US Building America guidance is that cross-ventilation does not work well in crawlspaces (EV9). Hill’s Ball State work found venting cannot be relied on to remove moisture from crawl spaces and can deposit extra moisture when warm, humid outdoor air enters a cool space and reaches saturation (EV151). Louisiana field houses showed outdoor-air ventilation may raise or lower wood moisture content depending on outdoor vapour pressure, crawlspace vapour pressure and wood surface temperature (EV222). BRANZ-linked New Zealand work recorded metals near subfloor vents corroding faster than metals in the middle of the space (EV95).
BRANZ work cited by McNeil and colleagues established that up to 40 litres of water vapour a day can evaporate from exposed ground into the subfloor air. If that load is not controlled it can affect insulation performance, corrosion, timber moisture and the occupants above (EV93, EV96).
Field guidance used in the Louisiana raised-floor study is that mould growth on wood can occur above about 15–18% moisture content (EV221). Decay fungi are commonly held to need moisture above fibre saturation (~30% MC) to start, while propagation is inhibited below about 20% MC (EV220, EV169). Closed-cell foam floors in that same study stayed below 16% MC in plywood and 18% MC in solid wood in the cases reported (EV214).
The US EPA’s commonly cited indoor range is 30–50% relative humidity, with higher humidity associated with dust mites and mould (EV20, EV502, EV426). That is a humidity-management target, not a diagnosis on its own.
Guidance on wood floor assemblies reports that vented crawl spaces can run considerably cooler than outdoors and indoors, with higher RH, condensation and wood moisture than an open crawl space (EV170). Building an unvented crawl space is described as a way to control RH and prevent moisture accumulation in the floor (EV171). Australian housing is also described as highly susceptible to outdoor humidity partly because many houses have subfloor ventilation and naturally ventilated roof spaces (EV291).
Air moves through fibre insulation, which reduces its R-value and can carry airborne moisture into the material (EV1, EV225). Building America notes that fibreglass batts in a vented crawlspace ceiling sit cool on the underside; if those surfaces drop below dew point, condensation forms, damp batts insulate poorly and mould can grow (EV8, EV7). The Louisiana twelve-house study found seasonal moisture trends and subfloor readings above 20% MC with open-cell foam and kraft-faced glass fibre batts, and concluded those types do not reliably protect subfloors from seasonal moisture accumulation (EV219, EV215, EV591). Closed-cell spray foam is moisture-resistant and does not behave like fibreglass, which can retain water (EV45, EV371).
Water vapour carried in moving air through floor leaks is controlled with effective air barriers and air sealing (EV177, EV268). Research in hot-humid climates found subfloor moisture content generally decreased with less vapour-permeable under-floor insulation (EV393). Closed-cell foam in the Louisiana houses kept plywood and solid wood below the moisture contents associated with those seasonal spikes (EV214, EV215). That is moisture-and-air-path management, not a guarantee that mould cannot occur if another leak remains (EV150).
Yes. Physical removal of contamination is the primary means of remediation in the VBA-VU scoping material; attempts that only kill or encapsulate without dealing with moisture are not treated as sufficient on their own (EV153 source position). IICRC-aligned practice and the same VBA material both put discovering and removing the root moisture source first, including concealed growth in interstitial spaces (EV156, EV480). Spray Foam TAS’s mould work is framed around identifying that source and then changing the floor and perimeter conditions that keep feeding it — not a 100% health or eradication guarantee.
The VBA-VU scoping study noted there has been no solid precedent of authoritative Australian guidelines around unhealthy buildings arising from mould (EV155, EV479). That is why source-control and documented building-science practice matter more than a single treatment product claim.
Not reliably. Kempton and colleagues found rising damp mentioned in initial reports of four properties but identified as a possible problem in only one inspection, and not named as the main underlying cause (EV175, EV516). A University of Wollongong-linked reading of contractor practice in the claims sheet records exhaust fans installed in 63% of properties and ‘poor ventilation’ blamed in 71% of cases, with subfloor moisture often left out of the remediation story (EV564).
The VBA-VU indoor mould scoping study states that allocation of responsibility for condensation management would largely fall on homeowners without recourse (EV164, EV482). The National Construction Code revisions require water vapour and condensation risks to be managed to minimise impact on occupant health (EV166, EV484) — that is a design and construction duty, not a defect-warranty assumption.
Yes. CSIRO describes condensation as a major cause of moisture accumulation, leading to mould and to cosmetic and structural damage, including decay that can threaten structural integrity (EV80, EV83). Straube notes condensation in walls can cause puddles and, in extreme cases, rot framing; an air barrier is one way to help prevent that pathway (EV267). Exposed floor joists can rot, and the floor above a crawlspace can be damaged by airborne moisture (EV30, EV32).
No honest page should say that. Closed-cell underfloor foam can keep timber moisture contents lower and block air-carried vapour through the floor when it is installed as a continuous layer (EV214, EV177, EV393). Mould still needs a remaining moisture source to be removed — a roof leak, a wet garden bed against the wall, a high water table, or indoor vapour hitting a cold surface (EV81, EV150). Spray Foam TAS treats mould work as source control plus insulation and air sealing, not as a steriliser or a medical treatment.
Find the moisture source first (cladding, plumbing, or condensation / subfloor vapour) (EV150, EV156). Dry or remove what cannot be saved after the 48-hour window has passed (EV147). Then change the conditions that keep feeding the problem: air-seal floor leaks and the subfloor perimeter, and use a less vapour-permeable underfloor insulation where the floor is the pathway (EV177, EV393, EV207). Indoor habits still matter — showers, cooking and clothes drying add litres of vapour a day (EV400) — but they are not a substitute for fixing the fabric.
The Climate Council's 2022 report states the potential savings from insulation could be massive. Any home built before 2003 in Hobart is poorly energy efficient and losing almost $1,300/year without a proper insulation solution.
In most instances, every home can benefit from spray foam insulation; however, there's a range of factors that come into play when assessing suitability. Once our team has completed a thermal inspection of your home, we can let you know if spray foam is the best option for you.
Depending on where the foam is applied, spray foam can improve indoor air quality by creating a vapour barrier and regulating internal humidity levels. This can reduce the instance of mould growth and enhance the quality of air.
100%. Spray foam forms an airtight seal that completely blocks draughts from entering via your underfloor or walls, making it especially suitable for cold and draughty homes.
That's no problem. All of our projects start with a thermal assessment so we can provide you with a holistic solution that will get you the best possible results; then it's up to you to decide. We are more than happy to only address a specific section of your home, depending on your needs and budget.
Once we've completed the job, we run a second thermal assessment to confirm all draught spots and problematic areas have been fully addressed.
Leave that to us. Every home is different, and a range of essential factors come into play. Once we’ve completed a site visit, we’ll suggest an option we know will get you the results you need to improve your home's energy efficiency and comfort.
There’s a range of amazing benefits that come with insulating your commercial space with spray foam. These include:
- Reduced energy bills
- Improve the comfort of your employees
- Lower CO2 emissions
- Improved strength of building elements
- Increasing the longevity of your workspace
- Weather proofing
- Pest control
- Mould resistance
Every project is different, and the length of time can differ on a case-by-case basis. Typically, once we’ve performed a thermal assessment on your space, we’ll have a better idea of the length of time to completion. For most projects, we’re able to complete your insulation solution within a day.
Very minimally. Most projects are completed within a day and you should be able to resume typical business operations the next day.
We’ve completed a range of commercial projects, including SALCO Live Lobster Farm, Bass Strait Removals and more. To see a few commercial projects our team has completed, visit our project page.
Yes. Insulation provides your employees with a thermally stable, clean, pest-free environment.
Insulation has been shown to drastically reduce heating and cooling energy costs which is a major contributor to carbon emissions. Improving your business's insulation means reducing energy usage, equaling lower emissions.
