Underfloor insulation = toasty toes

More than 10% of the heat from your home can be lost through the floor. It's so important that all rental properties must have underfloor insulation and EECA has subsidies to encourage homeowners to insulate their subfloors too.

Underfloor insulation can reduce draughts as well as dampness as it can limit moisture from rising into the house from a wet or damp crawl space below. Limiting rising damp will create a warmer, drier room, and that's where a ground moisture barrier can also help. If you already have foil insulation, we can also help if it is torn or damaged.

80-100% underfloor insulation Subsidies.

Michelle, Whakatane

I'm really pleased with the work that was done and the house is much warmer and drier now. Thanks very much to all the team for a very good job. It was such a pleasure to have your guys here and hardly be aware that they were at work, they were polite, tidy and just quietly got on with it.

Alison, Northland

The sales person knew the information but there was no pressure. The installer was excellent and did a careful and tidy job and was very helpful with explaining the operation.
