Health and Mould

Is Your Home Making You Sick?

Understand how mould and 30 different contaminants can similarly affect your health

Modern buildings can look clean and functional but still contain invisible health hazards.

Many people live with building-related illnesses without realising their health may be affected by hidden mould, moisture damage, or any of 30 other indoor contaminants.
When symptoms persist or treatments fail to help, ongoing exposure is often the missing factor.

At Building Forensics, we identify these risks through data-driven investigation, medical collaboration, and proven decontamination methods, reducing hazards, supporting recovery, and preventing recurrence.

Potential symptoms

Mould exposure does not always present as a visible problem in a building. In many cases, individuals experience a variety of health symptoms without making the connection to their indoor environment. Understanding what to look for can be the first step toward identifying a hidden cause.

Conditions Explained

When symptoms persist or recur without clear medical explanation, it can be valuable to consider environmental contributors.

Certain chronic and inflammatory conditions are now recognised to be linked to indoor mould exposure. Below, we outline a few of the more commonly documented health impacts to help clarify what might be at play.

CIRS (Chronic Inflammatory Response Syndrome)

A complex condition triggered by exposure to biotoxins from mould and other sources, leading to immune system dysregulation.

PANS and
PANDAS

Childhood onset disorders often linked to inflammation and environmental triggers, including mould exposure.

Neurological
Impact

Memory issues, difficulty concentrating, and mood disturbances can arise dueto mould-related neurotoxins.

Gut/Immune
Disruption

Mould can interfere with gut health, inflammation, and immune function, particularly in those with underlying conditions.

Gynacological
Issues

Missed periods, early menopause, Miscarriage

Endocrine
Dysfunction

Mould can interfere with liver, heart and kidney health, as well as your thyroid, cortisol levels and estrogen or testosterone levels

There is a link

The connection between indoor environmental quality and chronic illness is increasingly acknowledged by leading medical bodies. Below are a selection of references that highlight the clinical importance of proper investigation and remediation

British Society for Ecological Medicine (BSEM)

“Physicians must be aware of the adverse effects of indoor dampness and mould exposure on respiratory health, particularly in patients with existing sensitivities or underlying conditions. Accurate diagnosis depends on environmental context as well as clinical symptoms.”

International Society for Environmentally Acquired Illness (ISEAI)

“Environmentally Acquired Illnesses such as CIRS often go undiagnosed due to a lack of awareness and testing. A collaborative approach involving both environmental assessment and clinical interpretation is essential for effective care.”

CIRSx Certification Training Manual

“For individuals with a known genetic susceptibility, exposure to biotoxins released by water-damaged buildings can lead to chronic systemic inflammation. Environmental remediation is not optional – it is medically necessary.”

World Health Organization (WHO)

“Exposure to indoor dampness and mould has been associated with increased risk of asthma, respiratory infections, and other adverse health effects. Public health responses should prioritise identifying and correcting these environmental risk factors, especially for vulnerable groups.”
