Key Takeaways
- Underlying Moisture Issues: The presence of mushrooms indoors typically indicates significant moisture problems, such as leaks or water intrusion, which can lead to mold growth and potential structural damage.
- Health Implications: Mushroom growth can pose health risks, including respiratory issues and allergic reactions, especially for individuals with sensitivities.
- Dry Rot Concerns: Mushrooms may signify dry rot, a serious condition where wood decays due to fungal activity, compromising the integrity of the structure.
- Immediate Action Required: If mushrooms are found, it’s crucial to address the underlying moisture problem promptly to prevent further damage and health hazards.
- Professional Assessment Recommended: Consulting with a damp surveyor or building professional is advisable to accurately diagnose and rectify the issue.
Causes of Mushroom Growth Indoors
If you have found mushrooms growing in your house, don’t be afraid! The actual mushrooms growing are probably harmless but hiding a deeper problem. Moisture and humidity create an ideal environment for fungi to thrive, leading to mushroom growth.
Excess moisture from leaking pipes, poor ventilation, and water damage contribute to a conducive environment for mushrooms to grow indoors. Most commonly, when a building floods and and is left to dry out on it’s own, fungi thrive. However, so do fungal spores.
The timber in the building provides a food source for fungi, promoting mushroom growth. This is also known as Dry Rot. Dry Rot is named after the condition that the rotten wood is left in once the mushrooms growing inside and on top have sucked out the moisture present.
Identification of Common Indoor Mushrooms
Areas prone to mould growth and mushrooms growing in your home are carpets, corners, walls and basements. This is due to excess moisture inside the fibres of carpets or within the wood because of poor ventilation. There are several different types of mould species that can be found on the mushrooms inside your home.
Common mould species found on mushrooms include
- Aspergillus
- Penicillium
- Cladosporium
The mushrooms growing inside your home are likely to be relatively harmless but left for long enough and severe cases can produce mycotoxins which cause some health risks.
Health Risks Associated with Mushroom Growth
Indoor mushrooms can be a real danger to people due to mycotoxins released by mould spores, causing potential health risks. People may experience health effects from being exposed to , including symptoms like respiratory issues, allergic reactions, and more.
Mould exposure can be particularly harmful to the well being those with allergies and cause serious respiratory problems for those with respiratory conditions such as asthma or emphysema. If you have any underlying health issues, it is important that you find the root cause of the damp, mould and mushrooms growing.
Removing Mushrooms from Your Home
It may be tempting just to remove mushrooms as soon as you see them growing in your home. However, cleaning and disinfecting affected areas is crucial to removing mushrooms and preventing future growth. Removing mushrooms without addressing the underlying issue of moisture and mould growth will not provide a permanent fix.
Professional help and mould removal services may be necessary for extensive or persistent infestations. A damp survey will help identify areas of concern and how to combat persisting damp conditions.
Preventing Future Mushroom Growth
Creating a healthy living environment by controlling moisture and mold growth can prevent mushrooms growing in the first place. There are many preventive measures, from proper ventilation to good maintenance.
- Maintain optimal humidity levels between 30-50%. This is essential to preventing mushroom growth. Often, proper ventilation can be enough to prevent damp from ever developing.
- Mold spores are a precursor to mushroom growth, and their presence indicates a larger issue. Eliminating spores by improving air circulation, fixing leaks, and removing organic materials can prevent future mushroom growth.
- Preventative measures should be taken whether you have noticed damp or mushroom growth or not. Regular inspections are important, particularly in older buildings and basements.
- Another important preventive measure to avoid damp and mushrooms growing inside is to keep humidity in your home at an optimal level. Humid environments are a breeding ground for excess moisture, black mould and fungus. Your home should be at around 40%-55% humidity
If you are struggling to prevent mould or mushroom growth, have excess damp or any type of water damage, it may be necessary to have a professional damp survey to properly assess the problem.
Moisture Control and Ventilation
Mushroom growth is often a symptom of a larger issue, such as water intrusion, poor ventilation, or dry rot. Keeping control of moisture levels in the home is the best prevention technique. For example, kitchens and bathrooms should always be fitted with extractor fans (sometimes known as exhaust fans).
Another cause of moisture is water leaks, it’s important to check the most likely low light places for excess moisture such as basements for damp or attics for a leaky roof. Be sure check dark corners where you may find mushrooms growing.
Proper ventilation is key when moisture build up is an issue and you want to avoid persisting damp, mould or mushrooms appearing. Keeping windows open where possible to allow natural airflow alongside extractor fans in humid rooms will provide great ventilation. But sometimes it isn’t enough. A dehumidifier is great for keeping humidity low and has been shown to have great health benefits too.

Conclusion
Mushroom growth in your home can be a sign of underlying issues, such as dampness or dry rot. An affected area left untreated can cause structural damage, health issues and trigger allergies.
By understanding why mushrooms grow in the home, addressing the underlying issue, and taking preventive measures, you can create a healthy living environment and prevent future mushroom growth.

Frequently Asked Questions
Why are mushrooms growing in my house?
Mushrooms indoors are often a sign of excessive moisture, typically resulting from water leaks, poor ventilation, or high humidity levels. These conditions create an environment conducive to fungal growth.
Are mushrooms in the house dangerous?
While not all mushrooms are toxic, their presence indicates underlying moisture issues that can lead to mold growth. Mold exposure can cause respiratory problems and allergic reactions, posing health risks to occupants.
How can I remove mushrooms growing indoors?
It’s essential to first identify and resolve the source of moisture. Simply removing the mushrooms without addressing the root cause may lead to recurrence. Professional remediation may be necessary to ensure complete removal and prevention.
Can mushrooms cause structural damage?
Yes, mushrooms can be indicative of dry rot, a condition where wood decays due to fungal activity. If left untreated, this can compromise the structural integrity of your home.
Should I consult a professional if I find mushrooms in my home?
Absolutely. A damp surveyor or building professional can assess the situation, identify the underlying cause, and recommend appropriate remediation measures to prevent further issues.
