How to Get Rid of Winter Dampness and Mould for Good

Written by Bettina Diaz | Sep 4, 2025 6:30:00 AM

As winter winds down in Australia and spring rolls in, most of us are ready to fling open the windows, shake off the chill, and enjoy the sunshine. But there’s one winter souvenir many homes carry into spring: dampness and mould.

If you’ve noticed condensation on your windows, damp patches on walls, or those stubborn black spots in bathrooms and bedrooms, you’re not alone. Winter creates the perfect conditions for mould to thrive, and unless you deal with the cause, it won’t just disappear with the warmer weather.

Spring is the perfect time to tackle the issue head-on. Think of it as part of your spring cleaning—only instead of decluttering cupboards, you’re protecting your home (and your health) from something far more damaging. Here’s how to get rid of winter dampness and mould for good.

1. Understand Why Winter Leaves Dampness Behind

Cold air in winter can’t hold much moisture, which means condensation builds up on windows, walls, and ceilings. Add daily habits like hot showers, cooking, or drying clothes indoors, and you’ve probably had months of moisture hanging around your home.

Now that spring has arrived, the dampness left behind gives mould the perfect start to grow. That’s why acting now is key—cleaning up visible mould is good, but dealing with the underlying dampness is how you stop it from returning.

2. Refresh Your Ventilation for Spring

Warmer days mean you can throw open your windows and let fresh air in. Ventilation is the best friend of a dry, mould-free home. Get into the habit of opening windows for at least 15 minutes each day, especially after showers or while cooking.

If your home struggled with airflow through winter, it might be time to check your exhaust fans or even upgrade your ventilation system. Tradies can test whether your fans are working properly or install new ones so you’re ready for the year ahead.

3. Tackle Leftover Condensation

Condensation won’t be as big a problem in spring as it is in winter, but it can still happen in cool mornings and evenings. Instead of wiping it away each day, look at longer-term fixes.

  • Try a dehumidifier in rooms that stay damp.

  • Use your bathroom fan well into spring to keep moisture moving.

  • Dry laundry outside in the sunshine whenever you can—spring is perfect for it.

Persistent condensation is often a sign of poor insulation or draughts, which are worth having a professional look at before next winter rolls around.

4. Give Mould a Proper Spring Clean

If mould has built up over winter, now is the time to deal with it properly. Remember, scrubbing it away isn’t enough—it needs to be killed at the root.

  • Vinegar spray: A natural, effective solution for most small areas.

  • Commercial mould treatments: Quick results, but many don’t prevent regrowth.

  • Professional removal: The best choice if mould has spread or keeps returning.

Spring cleaning isn’t just about wiping cupboards and dusting blinds—add mould removal to your list and your home will feel genuinely fresher.

5. Insulation and Heating Prep for Next Winter

Here’s the thing: spring is the best time to think about your insulation and heating, because you’re not relying on them daily. Poor insulation and draughts are what caused much of that winter dampness in the first place.

Tradies can:

  • Upgrade insulation in walls, ceilings, or floors.

  • Draught-proof doors and windows.

  • Help you plan efficient heating for next winter.

Do it now and you’ll avoid repeating the same mould issues when cold weather returns. Plus, your home will be cooler in summer and warmer in winter—a win all round.

6. Don’t Ignore Leaks

Spring showers might still bring unwanted water into your home if you’ve got hidden leaks. Mould patches near ceilings, skirting boards, or plumbing often point to leaky roofs, gutters, or pipes.

This is where tradies are worth their weight in gold. They can inspect, detect, and repair leaks before they cause lasting damage. A small fix now saves you a massive repair bill later.

7. Know When It’s Time to Call a Pro

A little mould on your shower tiles is a DIY job. But mould that keeps coming back—or spreads across walls, ceilings, and carpets—means the problem is bigger than you can scrub away.

Professionals don’t just remove mould; they:

  • Identify if it’s surface-level or structural.

  • Use treatments that prevent it regrowing.

  • Fix the cause, whether it’s leaks, poor airflow, or insulation gaps.

Spring is the ideal time to bring in experts. Your home gets a reset, and you’re set up for a healthier, drier year ahead.

9. Keep Dampness Away All Year

Once you’ve tackled winter’s leftovers, stay on top of prevention. In spring and summer, that means keeping up with airflow, using fans when needed, and checking for leaks after heavy rain. The goal is to make dampness and mould unwelcome guests in every season.

By staying proactive, you’ll not only protect your home but also make it a healthier place for your family. No more coughing fits from hidden mould, no more musty smells—just a fresher, cleaner space to enjoy as the weather warms up.

Final Word

Spring is all about fresh starts—and what better way to start than by getting rid of the winter dampness and mould that’s been hanging around? While sprays and quick cleans help short-term, the only real solution is dealing with the cause: leaks, poor ventilation, or insulation problems.
