Most insulation jobs in Sydney homes are finished in a single day. A roof or underfloor install usually takes a crew of two to three installers a few hours, and roof and underfloor together can be done in around four hours. Wall insulation in existing homes, and homes with very tight access, take longer and can run over two days.
What Changes the Time on Site in a Sydney Home
The biggest factor is the size and access of the space being insulated. A roomy roof space with a standard manhole is quick to work in. A low-pitched roof, a narrow subfloor or a federation home with obstructions under the floor takes more care, and our installers work around cables, ducts and old floorboards rather than rushing through.
What’s already there matters too. If old loose-fill or failing insulation needs to be vacuumed out first, that removal is done before the new product goes in, which adds time to the day. Topping up over sound existing insulation is usually faster than a full removal and replacement.
Wall insulation has more steps. In brick veneer homes we pump INSULBLOC® into the wall cavity from the roof space, then remove and re-mortar a few bricks under windows to reach the sections below them. Timber-framed walls are filled through small holes in the plasterboard, which are patched once the cavities are full.
Before any of this, there’s a free measure and quote at your home. That visit is where our team checks access, confirms the products and gives you a realistic idea of how long the crew will be there. Depending on the schedule, installs can follow soon after, and clean-up at the end is part of the job.
