How to Get Rid of Damp Smell: Effective Solutions and Tips

Damp smells in the home are an all-too-common problem, especially during the colder months or in areas with high humidity. The musty odour is often caused by mould, mildew, or trapped moisture, which can lead to uncomfortable living conditions and even health issues if not properly addressed. 

Whether it’s a lingering scent in the basement, bathroom, or other damp-prone areas of the home, getting rid of the smell requires a multi-faceted approach. This article will explore various techniques for eliminating damp odours, while subtly introducing effective solutions like Sassy Scents’ products to help freshen and deodorise your space.

What Causes a Musty, Damp Smell?

Damp smells are typically caused by excess moisture trapped in your home, creating an environment conducive to the growth of mould, mildew, and bacteria. When moisture accumulates and isn’t properly ventilated or removed, it leads to a musty, unpleasant odour that can linger in affected areas. Here's a breakdown of the primary causes of damp smells:

1. Mould and Mildew Growth

Mould and mildew thrive in damp, humid environments. When moisture accumulates on surfaces like walls, ceilings, floors, or fabrics, these fungi can grow, releasing spores into the air. These spores emit a characteristic musty smell that’s often associated with damp environments. Mould and mildew not only cause odours but can also pose health risks, especially for individuals with respiratory issues or allergies.

2. Excess Moisture or Humidity

Humidity is one of the primary causes of damp smells. When the air is excessively humid, it can condense on cold surfaces like windows, walls, or pipes, creating pockets of moisture. If the moisture isn't properly ventilated, it can lead to a build-up of dampness, encouraging mould and mildew growth. High humidity in areas such as basements, bathrooms, and kitchens, where moisture levels are higher, can make the smell more pronounced.

3. Leaks and Water Damage

Leaks in plumbing, roofs, or windows allow water to enter walls, floors, and ceilings, where it can become trapped. Water damage can cause structural elements of the building to absorb moisture, leading to both physical damage (like wood rot) and the development of damp smells. Over time, standing water or prolonged wet conditions encourage the growth of mould and bacteria, which release odour-causing compounds into the air.

4. Poor Ventilation

Inadequate airflow can contribute to the persistence of damp smells. Areas such as basements, attics, and bathrooms, which are often poorly ventilated, trap moisture in the air. Without proper airflow to allow the moisture to escape, the dampness becomes trapped and stagnant, which fosters the growth of mould and mildew, making the smell worse.

5. Flooding and Storm Damage

Flooding caused by heavy rain, burst pipes, or other water sources can introduce large amounts of moisture into your home. If water isn't properly removed or dried out, it can seep into walls, carpets, and furniture, leaving behind a lingering damp smell. In addition to mould growth, bacteria from floodwater can further contribute to unpleasant odours.

6. Damp Building Materials

Some building materials, such as wood, concrete, or drywall, can absorb moisture from the environment. Over time, these materials can start to break down or degrade due to prolonged exposure to moisture, releasing musty smells into the air. This can happen especially in places that are prone to water exposure, such as basements or rooms with poor insulation.

7. Sewage or Drainage Problems

Clogged or broken drains can cause stagnant water to collect in sinks, bathtubs, or pipes. If sewage systems aren’t working properly, the smell of dampness can be exacerbated by the growth of bacteria and other organisms in standing water. This issue is common in basements, where drains can get blocked or back up, leading to both foul smells and moisture build-up.

8. Fabric Absorption

Furniture, curtains, cushions, and carpets are absorbent materials that can trap moisture and smells. Damp fabrics not only hold onto moisture but also encourage the growth of mildew and bacteria. The result is that your upholstered furniture and soft furnishings will develop a musty smell, contributing to the overall damp odour in your home.

9. Bacteria and Decomposing Organic Matter

In some cases, the damp smell can also be a result of decomposing organic matter, such as pet urine, food, or dead insects trapped in moisture. When these materials break down, they can release foul-smelling gases, adding to the overall damp odour in your home.

Getting Rid of Damp Smells

The primary cause of damp smells is the presence of excess moisture in the air and on surfaces, which promotes the growth of mould, mildew, and bacteria. It is essential to address the source of the moisture, such as leaks, poor ventilation, or humidity, and to properly clean and dry affected areas. Regular maintenance and the use of moisture-absorbing products can help keep damp smells at bay and maintain a fresh environment in your home: 

Step 1: Identify and Eliminate the Source of Moisture

The first and most important step in eliminating damp smells is identifying the source of moisture. Damp odour is typically a result of excessive moisture in a room, which allows mould and mildew to thrive. To prevent further odour issues, it’s essential to address the source of moisture directly. For leaks, repair the issue immediately. For condensation, consider improving ventilation, using dehumidifiers, or insulating walls and windows. For poor ventilation, use extractor fans or open windows regularly to allow air to circulate. Once the source of moisture has been controlled, you can focus on eliminating the damp smell.

Step 2: Use Absorbent Materials to Dry Out Damp Areas

Once you've addressed the root cause of the damp, the next step is to dry out the affected areas. Various materials can help absorb moisture and reduce the damp odour in your home:

1. Baking Soda: Baking soda is a well-known moisture absorber. Simply place open boxes or bowls of baking soda in damp areas to absorb excess moisture. You can also sprinkle baking soda directly on carpets, upholstery, or fabrics that have absorbed moisture, then vacuum it up after several hours.

2. Activated Charcoal: Activated charcoal is another effective moisture absorber. It works by attracting and trapping moisture particles, preventing them from causing odours. Place bags or containers of activated charcoal in damp areas to help eliminate the smell of dampness.

3. Desiccants: Desiccants, like silica gel, are commonly used in damp-prone areas to absorb moisture. They can be placed in areas such as closets, drawers, or cabinets to reduce humidity levels and prevent the development of damp smells.

4. Dehumidifiers: A dehumidifier is an essential tool for reducing moisture in the air. By drawing excess moisture from the room, it helps to prevent the growth of mould and mildew while also reducing the damp smell.

While these methods are effective for absorbing moisture, they do not directly eliminate the odour itself. This is where additional odour-eliminating steps are necessary.

Step 3: Clean Affected Surfaces

Dampness and moisture can cause mould and mildew to grow on surfaces such as walls, ceilings, floors, and furniture. To fully tackle the damp odour, it’s essential to clean these surfaces thoroughly:

1. Clean Mould and Mildew: If you find mould or mildew on walls, floors, or other surfaces, you need to clean it with a mould-killing solution. A mixture of equal parts water and white vinegar is a natural and effective way to kill mould and mildew without harsh chemicals. Alternatively, commercial mould cleaners can be used for more stubborn infestations.

2. Wash Fabrics: Fabrics, such as curtains, upholstery, bedding, and carpets, are notorious for absorbing damp smells. Wash any washable fabrics in hot water with a detergent designed for removing odours. For non-washable items, such as cushions or mattresses, try sprinkling them with an odour-eliminating powder (more on this later) or vacuuming with a strong vacuum cleaner that has a good filtration system.

3. Steam Clean: Steam cleaning is a great option for sanitising fabrics and carpets that have absorbed moisture. The heat from the steam not only kills bacteria and mould but also helps lift the damp particles that are trapped in the fibres.

Step 4: Use Natural Deodorisers

After cleaning the affected surfaces, it’s time to tackle the damp smell in the air. Natural deodorisers can help neutralise musty odours, leaving your home smelling fresh and clean. Some options include:

1. White Vinegar: White vinegar is a versatile deodoriser that can be used to eliminate damp smells. To use vinegar as a deodoriser, place bowls of white vinegar around the room or use a spray bottle to mist the affected areas. The vinegar will absorb the damp smell and leave your space smelling fresh.

2. Essential Oils: Essential oils such as tea tree oil, eucalyptus, or lavender can help eliminate damp smells while also adding a pleasant fragrance to the air. Simply add a few drops of essential oil to a bowl of water and let it evaporate in the room. You can also add essential oils to a diffuser to create a fresh-smelling atmosphere.

3. Baking Soda: As mentioned earlier, baking soda is not only effective at absorbing moisture, but it also neutralises odours. You can place bowls of baking soda around the room or sprinkle it on carpets and upholstery, allowing it to sit for a few hours before vacuuming it up.

1. Use a Dehumidifier: Invest in a dehumidifier to keep the humidity levels in your home under control. This will help prevent the growth of mould and mildew, and keep the air fresh and dry.

2. Ensure Proper Ventilation: Regularly open windows to allow fresh air to circulate and reduce humidity levels. Install extractor fans in damp-prone areas like bathrooms and kitchens to help moisture escape.

3. Regular Cleaning: Keep your home clean and dry by regularly vacuuming carpets, wiping down surfaces, and washing fabrics that are prone to absorbing moisture. This will help prevent the build-up of moisture and damp odour.
