“Our 1920s weatherboard was impossible to heat. Pro Insulation re-did the ceiling and underfloor in a day - our first gas bill dropped by $340. Can't believe I lived with it the old way for so long.”

Is this your house?
Period homes on stumps lose heat straight into the subfloor. These are the signs it is yours.
- 01
Socks on, still cold feet
Timber floors over an open subfloor sit close to outside temperature all winter. Batts under the boards stop the cold-plate effect you feel through socks.
- 02
Draughts up through the floorboards
Gaps between boards pull air from the subfloor every time the heater runs. Batts between the joists block the path, and we flag the gaps that need sealing.
- 03
A weatherboard or brick home on stumps
The classic Melbourne house. Underfloor is the second upgrade after the ceiling, and the two together are the package most homeowners choose, from $5,090.
- 04
Ceiling done, floors still cold
An insulated ceiling with an uninsulated floor still loses about 18% of its heat downwards. The floor is the next layer.
What goes in
Earthwool R2.5 between the joists, held with breathable mesh.
Friction fit alone sags within a few winters. Mesh on every joist bay keeps the batts where we put them.
- Knauf Earthwool underfloor batts
What that means on the day
- Batts cut to the joist spacing, so there is no sag and no gap at the bearers.
- Breathable mesh holds every batt so nothing drops in 10 or 20 years.
- Plumbing, wiring and damp flagged before we start, in writing, not covered up.
- Photos from under the floor at hand-over, so you see the finished bays without crawling under.
How it works
From a written quote to warm floors. Five steps.
Floor area comes from your plans or aerial imagery. The subfloor is inspected before any batt goes under.

About the VEU rebate
The VEU rebate applies to ceiling insulation only.
Victorian Energy Upgrades activity 48 covers ceiling insulation in existing homes. It does not cover this service. If your ceiling also needs work, that line of the quote may qualify and the rebate comes off it before you pay.

What homeowners say after the install
Why Pro vs the rest
Under the house, nobody is watching. That is where the jobs differ.
Underfloor batts are only as good as what holds them up. Here is what to ask any installer.

Comparison reflects common practice. Ask any installer how the batts are held up and whether you get photos.
