Underfloor Insulation Services

Underfloor insulation keeps your home warmer, drier, and more comfortable

Professional underfloor insulation for New Zealand homes

If your home feels cold underfoot or loses heat quickly, underfloor insulation is one of the most effective upgrades you can make.

It helps block cold air from entering your home, improves warmth at ground level, and supports a drier, healthier indoor environment.

We install high-quality underfloor insulation that matches New Zealand building standards and Healthy Homes requirements.

Homes with timber floors benefit the most, but many homes with accessible subfloor spaces can see significant improvements.

Why underfloor insulation matters

Cold floors are a common issue in New Zealand homes, especially those built with suspended timber floors. Without insulation, cold air rises through the floor and spreads through the home, making heating systems work harder.

Underfloor Insulation FAQ’s

  • Older homes with suspended timber floors benefit the most from underfloor insulation. Homes on concrete slabs do not require it. If you’re unsure if your house is compatible, get in touch and we’ll be happy to help with an assessment.

  • Not always. We can often access the subfloor externally. We can assess access during our initial inspection of your property.

  • Yes, older homes with suspended timber flooring will see huge benefit in underfloor insulation. If your home has limited access or space, underfloor may not be an option. Talk to us to find out what other options may be available.

  • The best option depends on your home’s structure, but most NZ timber floor homes perform well with moisture-resistant polyester insulation. It is safe, non-allergenic, and fits securely between joists. Rigid polystyrene panels are another strong choice for reducing draughts and moisture in homes with exposed subfloors. We assess your home and recommend the insulation type that delivers the best long-term warmth and performance.
