Insulation Removal Perth: Old Batts Out, Bradford Gold In
Whether you're cooling a new home or an existing one…
Insulation removal in Perth means safely taking out old, damp, contaminated or collapsed insulation, vacuuming the roof space and installing new insulation in its place. EIS does this across the Perth metro area, usually in a single visit, and reinstalls Bradford Gold batts at R4.1 to R5.0 (the NCC 2022 minimum for Perth ceilings is R4.0). A free roof space assessment tells you whether you need removal or a simple top up.
When Old Insulation Stops Doing Its Job
A Perth roof space can reach 60°C in summer, and insulation that is wet, chewed, collapsed or simply worn out lets that heat push straight into your living areas. If your home was built before 2003, there is a good chance the insulation is either below current NCC standards or has degraded over time.
Topping up does not fix material that has already failed, and new batts laid over damaged insulation lock the problem in. That is why our first step is always an honest look at what is up there, before we recommend removal or a top up.
Remove and Replace, or Top Up?
The answer depends on the condition of your existing insulation, not just its age. This is the checklist our team works through in every roof space.
Removal is needed if you have
- Water or storm damage. Wet insulation loses its thermal value and promotes mould.
- Animal contamination. Rodent or bird droppings, bacteria and parasites.
- Mould or deterioration. Compacted, torn or blackened batts.
- Hazardous or outdated pre-2000 material. Products no longer considered safe.
- Collapsed batts. Compressed insulation delivers a fraction of its rated R-value.
A top up is fine if all of these are true
- Existing batts are dry and fully intact
- No contamination, mould or animal activity
- Existing R-value is R2.0 or above
- The insulation is less than 20 years old
- No evidence of roof leaks in the cavity

What Affects the Cost of Insulation Removal in Perth?
No two roof spaces are the same, which is why we quote after we have seen yours. The main things that move the price are:
- Size of the roof space. More ceiling area means more material to remove and more to reinstall.
- Type of insulation. Batts are generally quicker to remove than blown-in loose fill.
- Condition. Wet, mouldy or contaminated material takes more care and more time.
- Access. A tight hatch or low, cramped roof space slows the job down.
- What goes back in. Removal only is cheaper than removal plus new Bradford Gold batts, but a roof left bare costs you in comfort and energy every summer.
According to the Australian Government's energy.gov.au, quality insulation reduces heating and cooling costs by around 30%. Ready for a number?
Can You Remove Insulation Yourself?
Yes, plenty of homeowners do, usually by hiring an insulation vacuum. Here is an honest comparison so you can decide.
| Product | Supply & Install (per unit) | Best for |
|---|---|---|
| Best for | A small area of dry, uncontaminated batts | Contaminated material, blown-in loose fill, or a whole roof |
| Conditions | Hot, dusty work in a roof space that can reach 60°C, so early mornings or cooler months are best | Handled by a trained team with the right equipment |
| Access and safety | You can only stand on the joists, and you work around wiring and downlights | Experienced in moving safely through Perth roof spaces |
| Disposal | You bag, transport and dispose of it yourself | Bagged and disposed of for you |
| New insulation | A separate job to organise afterwards | Bradford Gold reinstalled in the same visit |

FAQ - Insulation Removal Perth
Answers to the most common questions about insulation removal in Perth.
How much does insulation removal cost in Perth?
The cost depends on the size of your roof space, the type of insulation being removed (batts are generally quicker to remove than blown-in loose fill), how contaminated or damaged it is, how easy the roof space is to access, and whether new insulation is going in afterwards. EIS assesses your roof space first and gives you a free quote, so you know the cost before any work starts.
Should I remove old insulation or just top it up?
Top up only if all of these are true: the existing batts are dry and intact, there is no contamination, mould or animal activity, the existing R-value is R2.0 or above, the insulation is less than 20 years old, and there are no signs of roof leaks. If any one of those fails, removal comes first. EIS checks this at the free roof space assessment before recommending either option.
Can I remove insulation myself?
Yes, many homeowners do, usually with a hired insulation vacuum. It is hot, dusty work in a roof space that can reach 60°C in a Perth summer, you can only stand on the joists, and you need to work around wiring and downlights and dispose of the material properly. DIY suits a small area of dry, uncontaminated batts. For contaminated material, blown-in loose fill or a whole roof, most people prefer a professional team.
How long does insulation removal take, and is new insulation installed the same day?
It depends on the size of the roof space and the type of insulation, but EIS removes the old material, vacuums the roof cavity and installs the new Bradford Gold batts usually in a single visit, so your home is not left without insulation.
What happens to the old insulation?
It is safely removed, bagged and disposed of, and the roof cavity is vacuumed clean before the new insulation goes in.
Does my Perth home have hazardous old insulation?
Possibly, if it was built before 2000. Some older Perth homes have insulation that has degraded, been contaminated by rodent droppings or bird mites, or was made from products no longer considered safe. EIS includes a roof cavity inspection with every assessment, identifies any contaminated or compromised material, and advises whether it should be removed before new batts go in. If removal is needed, we handle it safely in the same visit.
