A home is a haven where people spend quality life with their loved ones. But what if your beautiful abode is filled with unpleasant, stale and musty odours? No matter how well you spruce up walls, windows and floors, lingering smells can ruin the entire feel and ambience of your residential space.

As a responsible Sydney tenant, it is imperative to identify the potential source of the musty smell and combat it using the best methods. It could be due to poor ventilation, mould and mildew infestation, unattended pet stains, plumbing issues and bathroom condensation.

Make sure you refer to your property condition report, complete repair work beyond fair wear and tear, conduct a guaranteed end of lease cleaning Sydney and neutralise bad smells to pass your final rental inspection. Here is a comprehensive guide on causes and key solutions of unfamiliar musty odours in a rental home. Follow this guide to create a fresh smelling, pleasant indoor environment.

1. What are the Common Causes of Musty Smell in a Home?

The stubborn stench is often the aftermath of lingering dampness, condensation and other issues that gradually increase over time. Here are some of the common causes that you must address for better outcomes:

High Humidity Levels:

Humidity above 50 per cent can breed mould and lethal bacteria, leading to a persistent bad smell. Excess moisture inside your home, especially in carpets, furniture coverings, and curtains, can harbour bacteria that cause musty odours.

Plumbing Issues or Leaky Roofs:

Believe it or not! Minor leaks under sinks, wash basins, and around taps can cause water damage, leading to dampness and musty odours. Even leaky roofs lead to moisture buildup that can weaken the property’s structure.

Poor Ventilation or Condensation:

Enclosed bathrooms, basements, tucked away lofts and chamber like rooms don’t have proper ventilation systems. Stagnant air can breed harmful germs and cause musty smells.

Inefficient HVAC Systems or Dirty Filters:

Air filters and ducts tend to capture dust and grime and can circulate musty smells throughout your abode. This not only harbours germs and bacteria but can also trigger respiratory problems, such as coughing, breathing difficulties, sneezing, and wheezing.

Humidity Absorbing Materials:

Bricks, wood framing, carpets, insulation and wallpaper can sometimes absorb excess moisture and release unpleasant, musty odours. If the smell persists after cleaning, then replace materials with mould resistant items.

Unnoticed Mould and Mildew Stains:

Musty odours are often triggered by mould infestation. Mould and mildew are common fungi that often grow in dark and humid conditions. So, all are interlinked. Make sure you ensure proper ventilation, control humidity and address plumbing issues and condensation to prevent moisture buildup.

2. How to Remove Mould Stains Naturally Before Banishing Musty Smell?

It is essential to check dark and humid areas in your rental home. This includes a bathroom, tile grout lines, the area under the kitchen sink, the shower area, curtains, the area around washbasins, basement walls, and carpets.

To remove mould stains from non porous surfaces like window glasses, plastic, metal, etc, spray white vinegar solution. Leave it for a few minutes and achieve spotless results.

For tile grouts and other delicate surfaces, apply 3 per cent of hydrogen peroxide and leave it for a few minutes until you scrub with a soft bristled brush.

Make sure you wipe and dry the surface to prevent regrowth. Also, regularly clean your home to keep mould and mildew at bay.

3. Banish Musty Odours with Baking Soda

Apart from rising your cakes and cookies, baking soda can do wonders in neutralising musty smells from your home. Whether it is due to humidity or poor ventilation, all you need to do is to place a bowl of baking soda in corners and closets. It will naturally absorb bad smells without releasing strong fumes.

You can also pour a generous amount of baking soda on your carpets and upholstery furniture. Make sure you vacuum the delicate surface the next day. If the smell still lingers or encountering with dust and debris when vacating your home, book professionals for an expert end of lease cleaning Sydney and prevent bond deductions.

4. How to Combat Musty Smell using Activated Charcoal

Activated charcoal naturally captures odours instead of masking them. It removes moisture, gases, and toxins from the air, reducing the sources of smell. You can place charcoal bags near vents, enclosed bathrooms, inside cupboards, and other areas with stagnant air to banish musty odours.

5. Essential Oils Can Do Wonders

Replace chemically laden room fresheners with natural essential oils. You can use tea tree oil, eucalyptus, lavender and lemon in a white vinegar solution and spray it in the room. You can also use citrus peels and herbs that simmer away on your stovetop. This will freshen up your home like never before.

6. Promote Fresh Air

Whether it’s a high rise apartment or a studio apartment, you should bring in natural light and fresh air to banish lingering odours. It is good to open doors, windows and curtains for a few minutes to freshen up the indoor air. You can also install indoor plants, such as peace lilies, English ivy and spider plants, to refresh the indoor air quality. These plants tend to pull in humidity and filter some airborne pollutants, promoting a fresh and breathable home environment.

7. Control Humidity Levels

Humidity is one of the major causes of musty odours. So, it is good to maintain indoor levels between 30 and 50 per cent by installing dehumidifiers and energy efficient ERVs. This will help remove excess moisture while improving indoor air quality.

8. Clean or Replace Air Vents

Make sure you deep clean air vents to remove dust mites, debris, and pollen using a vacuum cleaner. You can also soak the filters in hot, soapy water to banish stuck grime and gunk. If required, replace the dirty air filters with a new one to prevent bond deductions. For a budget end of lease cleaning Sydney, choose the most reliable company and pass your rental inspection.
