A musty home is not only unpleasant but can also be concerning. Here are some potential sources of the odor, along with strategies to prevent it from recurring.
Are you wondering why your house smells musty? These unpleasant odors can be caused by a range of issues, from improperly dried linens to dampness and mold. No matter the cause, a musty smell is often worrisome and should always be investigated.
The positive news is that most musty odors do not indicate a serious problem and can often be resolved quickly. However, certain musty scents may signal more troubling issues, such as dampness and mold, which should be addressed promptly.
Here, experts outline seven potential reasons for a musty odor in your home and provide effective solutions to restore a pleasant ambiance.
What Causes a Musty Odor in My Home?
1. Mold and mildew
The most prevalent reason for a sudden musty odor in a home, particularly during winter, is the growth of mold and mildew, typically arising from high humidity and condensation. A musty scent, especially when paired with dark discoloration on walls, furnishings, ceilings, or carpets, may be the initial indication of spore development.
‘Mold typically produces a strong, musty odor due to the release of specific chemicals known as microbial volatile organic compounds (mVOCs) during its growth and decomposition of materials,” explains Michael Rubino, an expert in mold and air quality, as well as an environmental wellness advocate and founder of HomeCleanse. He elaborates, “For instance, when mold feeds on damp wood, paper, or fabric, it generates byproducts that contribute to that characteristic scent.
‘Various types of mold, such as Aspergillus, Penicillium, and Cladosporium, can emit distinct odors, which is why you may detect variations in scent based on the specific mold present. Generally speaking, however, the odor is commonly characterized as earthy, musty, and reminiscent of a cigar.’
If you detect this odor in your home, it indicates an active mold colony releasing gases; generally, the more significant the issue, the stronger the scent.
Fortunately, eliminating black mold yourself is quite manageable if you catch it early. However, be aware that it will likely return unless you enhance ventilation and address condensation on windows. One effective solution is investing in a quality dehumidifier; for instance, we recommend the GE Energy Star Portable Dehumidifier, available on Amazon, as our top choice.
Vinegar is an excellent home remedy for killing mold. Simply fill a spray bottle, such as the Equate 8 oz Plastic Spray Bottle available at Walmart, with vinegar, apply it directly to the affected areas, and rinse with very hot water, taking care not to scrub too aggressively. We suggest using Great Value Distilled White Vinegar from Walmart, which boasts a 5% acidity level strong enough to eliminate mold spores and inhibit their return.
For more stubborn patches of mold, consider purchasing a commercial mold spray.
2. Accumulation of dust and grime
If no sources of mold are evident in your home, the origin of the musty odor may be less concerning. “Musty smells are frequently the result of an accumulation of dirt and grime, leading to a persistent, unpleasant scent,” explains Amanda Lewis of Elbow Grease. “To eliminate these odors, it is essential to address the issue with a thorough cleaning of the affected areas.”
Fortunately, there are numerous cleaning tips that can assist you in maintaining a pristine home with minimal effort.
‘Whilst products such as air fresheners will help mask the smell, they won’t eliminate the cause,’ Amanda continues. ‘A product such as Elbow Grease’s All-Purpose Degreaser available at Amazon is designed to break down a build-up of dirt, including grease and oil, to eliminate the problem and to leave the home smelling fresh.’ You may also want to make dusting a regular part of your achievable cleaning routine, wiping surfaces with microfiber cloths, such as the HOMEXCEL Microfiber Cleaning Cloths available at Amazon.
3. Inadequately dried clothing and linens
While knowing how to dry clothes quickly is advantageous, failing to allow clothing and linens ample time to dry can result in a musty odor, potentially leading to a persistent scent in your home.
“Ensure your clothes have enough breathing room,” advises Matt Connelly, founder and CEO of the renowned NYC laundry service Ihateironing. “Crowding your items together in the closet can cause them to wear out more quickly due to friction, lint formation, and wrinkles. Moreover, this lack of proper air circulation can lead to a stale or musty smell on your garments.”
There are numerous benefits to air-drying laundry; however, if that isn’t feasible, consider using an indoor clothes airer, such as the Joseph Joseph Eclipse, which is ideal for compact spaces.
4. Home humidity levels surpassing 60%
Determining the ideal humidity levels for your home during winter can be challenging. However, humidity exceeding 60% can trap odors and contribute to a musty, damp smell lingering throughout your space, according to mold and air quality expert Michael Rubino.
Furthermore, elevated humidity can promote the growth of mold and mildew, exacerbating the odor and posing potential health risks.
To reduce humidity, a dehumidifier can be effective; alternatively, simply opening your windows for half an hour each morning upon waking can help lower moisture levels.
You can measure your home’s humidity using a hygrometer.
5. Inadequate ventilation
During winter, we tend to keep our windows and doors closed for extended periods, resulting in reduced airflow and inadequate ventilation within our homes. Consequently, moisture from our breath and odors from daily activities such as cooking, exercising, and cleaning can linger without proper outlets.
Effective ventilation is the simplest and most efficient means of preventing mold and musty odors. Even in the colder months, it’s essential to open windows to allow fresh air into your home. Curious about how often to open your windows in winter? Despite the chill, doing so can benefit both your health and your home, and it may even enhance your sleep quality.
In addition to opening windows, ensure that fans and ventilation systems are functioning optimally.
6. Worn or soiled carpets and rugs
A frequent source of musty odors in homes is carpets and rugs that are either aged or inadequately cleaned. It’s easy to assume that using one of the best vacuum cleaners a few times a week is sufficient to keep them fresh; however, it cannot replace the importance of knowing how to deep clean a carpet and doing so periodically.
“You should vacuum and use cleaning sprays weekly to maintain their cleanliness. Additionally, consider renting a carpet cleaning machine every three months,” advises Ivan Ivanov of End of Tenancy Cleaning.
“Don’t hesitate to vacuum more than once a week, especially if you have pets. Our furry companions bring in germs and bacteria from outdoors, so increasing your vacuuming frequency is advisable.”
Investing in a high-quality vacuum specifically designed for pet hair will help reduce pet dander and the lingering odors in your home.
7. Poorly installed insulation
Ultimately, poorly installed insulation could be contributing to musty odors in your home.
“Insufficient insulation can result in condensation within the walls,” explains mold and air quality expert Michael Rubino. There are various types of attic insulation, including foam board, blanket, and glass wool insulation, all of which can be utilized throughout the home.
You can explore how to insulate a garage door or a crawl space, but if you’re uncertain about handling the installation yourself, it may be wise to hire a professional handyman. This approach can help mitigate potential issues and avoid greater expenses in the future.

Is it possible for a house to have a musty odor without the presence of mold?
While a musty odor in a home is frequently indicative of mold and mildew, it can also stem from inadequate ventilation and an accumulation of dust and grime. If you cannot identify any signs of mold, dampness, or mildew (be sure to inspect deep corners and behind furniture), a thorough spring cleaning combined with opening the windows may help refresh your home and eliminate the unpleasant scent.
Can a musty odor lead to health issues?
Whether a musty odor can adversely affect your health depends on its source. If the scent arises from dampness and mold, inhaling spores could lead to negative health effects.
