How to warm up your home and increase its value

Many older homes across Wellington and Kāpiti aren’t equipped for energy efficiency or year-round comfort. Upgrading your windows, insulation, and heating systems can make your home warmer, healthier, and more affordable to run.

How to warm up your home and increase its value

We’ve got the expertise to add the most value to your home

If your home was built prior to the 1990s, chances are you’re living with original single-glazed windows, minimal insulation, and heating systems that just don’t cut it. With the colder months here, many Kiwis are feeling the pinch — both in temperature and in power bills.

At NZ Proud, we’ve seen a growing number of homeowners across Wellington and Kāpiti asking for help to improve the thermal performance and energy efficiency of their homes. Whether you're looking to stay warmer, lower your energy costs, or boost your home's resale value, upgrading your windows and insulation is one of the smartest investments you can make.

Why Thermal Upgrades Are Worth It

Improving your home’s thermal envelope — starting with windows, insulation, and ventilation — has a significant impact on:

  • Heat retention and comfort
  • Energy usage and power bills
  • Indoor air quality
  • Long-term home value

In fact, upgrading to modern aluminium joinery with thermal double glazing can improve window performance by 35–50%, while better insulation and ducted heating systems make a big difference in everyday comfort.

What NZ Proud Offers

We’ve worked hard to ensure our clients have access to affordable, high-quality thermal upgrades that suit both your home and your budget. Here’s how we can help:

1. Window Joinery Upgrades

We offer supply and installation of:

  • Thermal double-glazed aluminium joinery
  • uPVC and timber joinery options for different aesthetic and performance needs
    These options significantly reduce heat loss and drafts, making your home warmer and more efficient.

2. Ducted Heat Pumps & Ventilation

Integrated heating and mechanical ventilation options can help regulate temperature and manage moisture, contributing to a healthier home environment year-round.

3. Insulation Upgrades

We assess and upgrade ceiling, wall, and underfloor insulation to meet current standards and maximise thermal retention.

4. Solar System Options

For homeowners looking to reduce their environmental footprint, solar panels and energy storage systems are a smart addition to your energy-efficient upgrade package.

5. Help With Sustainable Lending (Low-Interest Loans)

Many New Zealand banks now offer sustainable home loans with rates as low as 1% for energy efficiency improvements. We can connect you with our trusted mortgage broker to:

  • Check your eligibility
  • Assist with your application
  • Help secure affordable finance for your upgrades

Why Upgrade Now?

With energy prices rising and sustainable lending options available, now is the ideal time to invest in your home's future. Many homes in Wellington and Kāpiti are overdue for window and insulation upgrades — and even modest improvements can dramatically enhance warmth, health, and value.
