Underfloor Insulation
Warm floors, no more draughts.
Suspended timber floors lose heat straight down into the subfloor. We fit insulation snugly between the joists so warmth stays in your rooms and cold air stays out.
On Site
The process of underfloor insulation.
An explanation of how we work under the floor — quote, access, prep and fitting each roll between the joists and stapling to secure the polyester.
How It Works
Our process, step by step.
Subfloor inspection
We check joist spacing, clearance, ventilation and moisture before quoting.
Product selection
We match the right R-value and product type to your subfloor and climate.
Stapled between joists
Polyester rolls are fitted between the joists and then stapled with air compressed staple guns to the side of the joists.
Clean finish
We ensure that there are no gaps throughout the install, tidy the site and walk you through the completed work.

Pricing
What does it cost?
The cost of underfloor insulation depends on your subfloor, so we give you a fixed price after checking under the house. The main things that affect the price are:
- The size of the floor area
- How much crawl space there is under the house
- The type of insulation chosen
- Joist spacing and subfloor layout
- Pipes, wiring and ducting to work around
