10 Best Ways to Keep Older Aussie Homes Warm This Winter

Written by Bettina Diaz | Jun 22, 2026 6:45:00 AM

There’s a lot to love about older Australian homes. Whether it’s a charming weatherboard cottage, a classic Californian bungalow, or a Federation-era beauty, these homes have character that’s hard to find in modern builds.

The downside? Many older homes were built before energy efficiency became a priority. As winter settles in, homeowners often discover that their house feels more like a wind tunnel than a cosy retreat.

The good news is that you don’t necessarily need a complete renovation to stay comfortable. With a few smart improvements, you can significantly reduce heat loss, lower energy bills, and make your home much warmer throughout the colder months.

Here are some of the best ways to keep older Aussie homes warm this winter.

1. Seal Gaps and Draughts

One of the biggest culprits behind a cold home is uncontrolled airflow. Older homes often develop gaps around doors, windows, skirting boards, floorboards, and even wall cavities.

These tiny openings allow warm air to escape and cold air to enter, forcing your heating system to work much harder.

Common draught-proofing solutions include:

  • Door seals
  • Weather strips
  • Window seals
  • Gap fillers
  • Door snakes

Many homeowners are surprised by how much difference simple draught sealing can make. A professional handyman or carpenter can quickly identify hidden gaps that are easy to miss.

2. Upgrade Your Insulation

Insulation is often the most effective long-term solution for keeping an older home warm.

Many homes built decades ago either have minimal insulation or none at all. Without proper insulation, heat escapes through the roof, walls, and floors.

Key areas to insulate include:

  • Roof and ceiling spaces
  • External walls
  • Underfloor areas
  • Attached garages

According to energy efficiency experts, a significant portion of a home's heat loss occurs through the ceiling. Upgrading roof insulation can therefore deliver immediate comfort improvements.

A qualified insulation installer can recommend the most suitable materials for your property and ensure they’re installed correctly.

3. Repair or Replace Old Windows

Windows are another major source of heat loss in older homes. Single-pane glass and ageing timber frames often allow warmth to escape rapidly during winter.

Depending on your budget, you could consider:

  • Repairing damaged frames
  • Replacing worn seals
  • Installing secondary glazing
  • Upgrading to double glazing
  • Adding thermal curtains

Double glazing is particularly effective in colder parts of Australia, but even simpler upgrades can make a noticeable difference.

A local window glazier can assess your existing windows and recommend practical solutions without necessarily requiring full replacement.

4. Install Heavy Curtains and Blinds

Many homeowners focus on heating but overlook the role of window coverings.

Thick curtains create an additional barrier between your living space and the cold air outside.

For the best results:

  • Choose thermal-backed curtains
  • Ensure curtains extend below the window frame
  • Close curtains as soon as the sun goes down
  • Use pelmets where possible

This simple upgrade can help retain warmth and reduce heating costs throughout winter.

5. Improve Underfloor Insulation

Older raised homes are particularly vulnerable to cold air entering from underneath.

If your home sits on stumps or has significant clearance beneath the floor, you'll often notice chilly floors during winter mornings.

Installing underfloor insulation can:

  • Reduce heat loss
  • Improve indoor comfort
  • Lower energy consumption
  • Eliminate cold spots

This upgrade is especially beneficial for weatherboard homes and older Queenslanders found across many parts of Australia.

6. Service Your Heating System

A heating system that hasn’t been serviced for years may not be performing efficiently. Dust, wear and tear, blocked filters, and faulty components can all reduce effectiveness.

Regular maintenance can help:

  • Improve heating performance
  • Reduce energy use
  • Extend equipment lifespan
  • Identify potential safety issues

Whether you use ducted heating, split systems, gas heaters, or reverse-cycle air conditioning, a licensed technician can ensure everything is operating as intended before winter reaches its coldest point.

7. Add Rugs to Timber Floors

Many older homes feature beautiful timber flooring. While these floors look fantastic, they can feel icy underfoot during winter.

Large rugs provide an extra layer of insulation and help retain warmth within living areas.

Consider placing rugs in:

  • Living rooms
  • Bedrooms
  • Hallways
  • Dining areas

This is one of the easiest and most affordable ways to improve comfort without major renovations.

8. Upgrade Exterior Doors

Older exterior doors often develop warping, gaps, and poor seals over time.

Even small openings can allow substantial heat loss.

Potential improvements include:

  • Replacing damaged doors
  • Installing weather seals
  • Upgrading door frames
  • Adding insulated doors

A professional carpenter can inspect existing doors and recommend cost-effective improvements that suit the style of your home.

9. Make the Most of Natural Sunlight

Australia may experience cold winters, but we’re fortunate to enjoy plenty of sunshine in many regions.

Taking advantage of passive solar heating can help warm your home naturally.

Simple strategies include:

  • Opening curtains during sunny periods
  • Keeping north-facing windows unobstructed
  • Trimming vegetation that blocks winter sunlight
  • Arranging furniture to maximise solar gain

This approach costs nothing but can contribute noticeably to indoor comfort.

10. Consider Energy-Efficient Home Improvements

If you're planning larger upgrades, winter can be the perfect time to improve your home's overall energy performance.

Popular options include:

  • Wall insulation upgrades
  • Double-glazed windows
  • Roof restoration
  • Ventilation improvements
  • Energy-efficient heating systems

While these projects require a larger investment, they often deliver long-term savings through reduced energy bills and improved comfort year after year.

Experienced tradies can help prioritise upgrades based on your home's specific needs and your available budget.

Why Professional Help Makes a Difference

Many homeowners attempt quick DIY fixes when winter arrives. While some improvements are suitable for DIY, larger projects often benefit from professional expertise.

Qualified tradies can:

  • Identify hidden sources of heat loss
  • Recommend cost-effective upgrades
  • Ensure compliance with building standards
  • Complete work safely and efficiently
  • Deliver longer-lasting results

Most importantly, professional assessments help avoid spending money on improvements that may not address the real problem.

Finding the Right Tradie for the Job

Every older home is different. What works for one property may not be the best solution for another.
