Toxic Mould Detection
Mould is a naturally occurring organism that feeds on dead organic material such as paper, timber and wood-based products. At low, typical levels it may be harmless, but when conditions allow mould to grow unchecked, it can become allergenic and, in some cases, toxic.
At Bristol Damp Solution, we provide professional toxic mould detection and assessment services to identify mould growth, understand the underlying causes, and advise on appropriate remediation.
Understanding Mould & Health Risks
Not everyone is affected by mould exposure in the same way. Individuals who are considered atopic — estimated to represent between 5% and 40% of the population — may experience more severe reactions.
Potential health effects associated with mould exposure can include:
Respiratory issues, including asthma
Skin irritation and rashes
Eye irritation and infections
Flu-like symptoms
Swelling of lips, throat or eyelids
Persistent sore throats or chest infections
Young children, elderly individuals, and those with weakened immune systems are generally more vulnerable. The severity of symptoms can also depend on exposure levels and duration.
Why Mould Develops in Buildings
Mould growth indoors is always linked to moisture. Common sources include:
Condensation
Rising or penetrating damp
Plumbing leaks or water ingress
Poor insulation
Inadequate or ineffective ventilation
Unless the moisture source is identified and resolved, mould is likely to return even after surface cleaning or treatment.
Can Mould Be Toxic?
Only a small proportion of mould species are capable of producing toxins, but these species can and do occur in buildings. Importantly:
Toxic mould cannot be identified by colour
Not all toxic moulds produce toxins at all times
Dead or dormant mould can still be allergenic or harmful
The use of inappropriate treatments (such as bleach) can sometimes increase toxin release
For these reasons, visual inspection alone is not sufficient to assess risk.
Professional Mould Inspection & Detection
Our mould detection services may include:
A detailed inspection of visible and suspected mould growth
Assessment of moisture sources and environmental conditions
Identification of hidden mould (e.g. behind wallpaper, within cavities or voids)
Mould sampling where appropriate to determine type and risk
Clear reporting on findings, causes and recommended next steps
Even where mould is visible, the true extent of growth is often concealed within the building fabric.
Signs You May Have a Mould Problem
You may wish to arrange a mould inspection if you notice:
Visible mould growth
Water staining or signs of damp
Persistent musty or mould odours
Unexplained health symptoms that improve when away from the property
Ongoing respiratory or skin issues affecting household members
Addressing the Cause, Not Just the Symptoms
Effective mould remediation starts with understanding why mould is present, not just removing what can be seen. Our approach focuses on identifying moisture sources, assessing risk, and providing practical guidance to prevent recurrence.
If you’re concerned about mould within your property, a professional inspection will provide clarity, reassurance, and a clear route forward.
