Underfloor
What underfloor insulation does
If your floors feel cold underfoot, the space beneath them is usually the reason. Underfloor insulation slows heat moving down through the floor, which helps keep your home warmer in winter and helps keep the floor surface warmer.
We install Mammoth underfloor insulation in homes with raised timber floors. It can make a noticeable difference in older homes, where there is often little or nothing under the boards.
We can fit a ground moisture barrier at the same time. It helps reduce damp rising from the soil, and it pairs well with underfloor insulation.
Quality products. Quick, tidy installs.

Underfloor insulation: common questions
Can't see your question? Give us a call.
How much does underfloor insulation cost?
As a guide, underfloor insulation is $2,200 to $2,500 for a 100m² home. Your quote depends on access and materials, such as how easy it is to get under the floor.
Will underfloor insulation work with my floor type?
It is for homes with a raised timber floor and space underneath. If your home sits on a concrete slab, there is no underfloor space to insulate, so ceiling insulation is the place to look.
Do I need a ground moisture barrier as well?
Often it makes sense to do both together. We look at the subfloor at the assessment and tell you whether a barrier is worth fitting with your insulation.
Do you install underfloor insulation in Gisborne and the Coromandel?
Yes. We started in Gisborne and still do plenty of work there, and we also install across the Bay of Plenty, the Coromandel and Hauraki, and Rotorua.
