Why invest in a healthy home?
A healthy home isn’t just comfortable and energy efficient – it’s essential for your family’s wellbeing.
Too many Kiwi homes are cold, damp, and expensive to heat. This can lead to:
- High power bills (usually from heating)
- Respiratory problems like asthma
- Mould and mildew issues
- Structural damage over time
The good news? Most homes can be dramatically improved with the right upgrades, done in the right order.

Top Healthy Home Upgrades
Retrofit Double Glazing
Double-glazing creates an insulating barrier that:
- Keeps warmth in during winter
- Helps keep your home cooler in summer
- Reduces condensation on windows
- Cuts down on outside noise
- Can reduce heating costs by up to 20%
Upgrading to double-glazed windows is one of the most effective ways to improve your home’s comfort and efficiency.
Higher Quality Insulation
- Ceiling insulation
- Underfloor insulation
- Wall insulation
How do you know if you need better insulation?
- Your home feels cold even with heating
- Your power bills are unusually high
- You notice condensation or mould issues
Good insulation doesn’t just save money – it creates a consistently comfortable home year-round.
Repair Drafts & Leaks
Water ingress is bad news. Even small leaks can lead to Rotting timber, structural issues and decreased property value.
Warning signs to watch for:
- Musty smells
- Visible mould patches
- Damp or soft areas on walls or ceilings
- Water stains
Addressing leaks early prevents bigger, more expensive problems down the road.
Heating & Ventilation
Once your home is properly insulated, an efficient heating system can transform your home.
Heating Options:
- Ducted heat pumps are the gold standard for heating
- Log Burners/Pallet Fires are cozy, and cost effective
- Gas Fires are stylish, convenience and controllable
The right heating system not only keeps your family comfortable but can significantly reduce your ongoing energy costs.
