Underfloor insulation
Warm floors, right through winter.
A huge amount of a home's heat disappears straight through an uninsulated floor. Underfloor insulation keeps that warmth where you want it, so your rooms feel cosier and your heating works less hard.
Why insulate below
The warmth you pay for should stay in the room.
In an uninsulated home, heat pours down through the floor into the cold subfloor and out of the house. Fitting insulation between the joists puts a warm blanket under your living space, so the heat you generate is the heat you keep.
Warmer floors
Insulation between the joists keeps heat in the room instead of losing it to the cold space below.
Lower power bills
A well insulated floor means your heating works less hard to hold a comfortable temperature.
No more cold draughts
Stop the cold air that rises through gaps in an uninsulated timber floor.
Healthier air
Paired with a moisture barrier, insulation helps keep the whole subfloor dry and mould-free.
How we fit it
A tidy job that lasts.
Assess and measure
We check joist spacing, clearance and any damp issues, and recommend the right product and R-value for your home.
Fit the insulation
Insulation is cut and fitted snugly between the floor joists with no gaps or sagging.
Secure and finish
Everything is held in place to last, checked for full coverage, and the site left tidy.
Common questions
Underfloor insulation, answered.
How much warmer will my home feel with underfloor insulation?
Most people notice the difference immediately: floors that are not cold underfoot, fewer draughts, and rooms that hold their heat for longer after the heater goes off. It is one of the most cost-effective comfort upgrades a Wellington home can make.
What R-value do I need in Wellington?
For our climate we fit insulation that meets or exceeds the current New Zealand standard for floors. We confirm the right value for your specific home during the assessment rather than using a one-size number.
Can you insulate under an older villa or bungalow?
Yes. Older Wellington homes are exactly where underfloor insulation makes the biggest difference. As long as there is safe access to the subfloor, we can usually fit it.
