Fact

About 30% of New Zealand homes are damp, and many houses have mould.

About 30% of New Zealand homes are damp, and many houses have mould. Dehumidifiers and ventilation systems help fix the symptoms of the problem, but don’t always tackle the cause itself. In many cases, dampness is relatively cheap and easy to fix.

Dollar for dollar, installing a ground moisture barrier is one of the best things you can do to improve the health and comfort of your home, without the price tag!

Many Kiwi homes suffer from damp and mould.

Dehumidifiers and ventilation systems help fix the symptoms of the problem, but don’t always tackle the cause itself. In many cases, dampness is relatively cheap and easy to fix.

Ground moisture barriers put a cap on rising damp, lowering the moisture level in your home. This reduces condensation and mould, making the air feel more comfortable and the home easier to heat. 

If you do it yourself, the cost will come in just over one dollar per square metre.

After we’ve assessed your home, we’ll let you know which affordable ground moisture barrier option will suit you.

And you might also be eligible for an insulation subsidy of 90% or more .

How to Check If There’s Excess Moisture in Your Home

If you can get under your floor, check for signs of dampness like mould. Take some dirt and rub it firmly on your hand – if it stains like mud there is too much moisture present.

  • Check for water getting under the floor from drainage, guttering, downpipes or plumbing problems
  • Install vents (if there aren’t any)
  • Uncover any vents blocked by plants, soil or pest barriers and clear the sub-floor area of any obstructions

If you’re not sure about any of these actions, we recommend you talk to one of our home energy assessors.
