DIY Ways to Keep Your Home Warm This Winter

Winter in South Africa brings crisp mornings, chilly evenings and that constant search for warmth at home. The good news? You don’t need to rely only on heaters or high electricity bills to stay cosy. With a few simple DIY upgrades, you can make your space warmer, more comfortable and energy-efficient.

Here are some practical, budget-friendly ways to keep the cold out and the warmth in this winter.

Seal Up Draughts

One of the biggest reasons homes feel cold is because warm air escapes through small gaps around doors and windows.

Easy fixes:

  • Use weather stripping around doors and window frames
  • Install door seals or make your own draught stoppers using fabric and filling
  • Seal visible cracks with silicone or filler from DIY Depot


This is one of the quickest and most effective improvements you can make.

Upgrade Your Curtains

Windows are a major source of heat loss, especially at night.

What you can do:

  • Swap out thin curtains for thicker, heavier ones
  • Use thermal or blackout curtains if possible
  • Keep curtains open during the day to let sunlight warm the room, then close them before it gets dark

Insulate Where You Can

Proper insulation can make a huge difference, but even small DIY steps help.

Try this:

  • Add insulation strips around windows
  • Use rugs or carpets on tiled floors to reduce cold underfoot
  • Place furniture strategically against walls to reduce exposure to cold surfaces

Fix Cracks and Gaps

Cold air sneaks in through more places than you’d expect.

Check for:

  • Cracks in walls
  • Gaps around skirting boards
  • Openings where pipes enter the home

Seal these areas with the right fillers or sealants to instantly improve warmth.

Use Rugs and Soft Furnishings

Hard floors can make a room feel colder than it actually is.

Simple upgrades:

  • Add rugs to living areas and bedrooms
  • Layer blankets and throws on couches
  • Use cushions to create a more insulated, cosy feel

These small touches not only keep you warm but also make your space feel inviting.

Switch to Warm Lighting

Lighting can impact how warm a room feels.

  • Use warm-toned bulbs instead of cool white
  • Add lamps for a softer, cosier atmosphere
  •  

It’s a subtle change, but it makes a noticeable difference in winter.

Don’t Forget Maintenance

Keeping your home in good condition helps it retain heat.

  • Check for leaks or damp areas
  • Clear gutters to prevent moisture build-up
  • Ensure doors and windows close properly
