ERMI Mould Testing Cascais
DNA-Based Mould Analysis for Indoor Environments
​ERMI (Environmental Relative Mouldiness Index) testing uses DNA-based analysis to identify specific mould species present in household dust. Unlike a visual inspection or a single air sample, ERMI testing provides a more detailed picture of mould contamination within a property.
​
ERMI mould testing is available for residential and commercial properties in Cascais and the surrounding Lisbon area.
​
Dust samples are collected from the property and analysed in a laboratory to identify mould species and measure their levels.
Why ERMI Testing
Moisture & Mould Assessment
We use moisture mapping to identify underlying moisture sources and conditions that may allow mould to develop.
Scientific Sampling
We collect targeted dust samples from key areas of your property for laboratory DNA analysis
Actionable Results
You receive a detailed report identifying mould species and measuring mould levels within your property.
Frequently Asked Questions- ERMI Mould Testing
What is an ERMI test?
The Environmental Relative Mouldiness Index (ERMI) is a DNA-based surface analysis that identifies specific mould species present in your home. It provides a more detailed, scientific assessment than a simple visual inspection.
Why should I choose ERMI over a standard mould test?
Standard tests often only look for visible growth. ERMI testing uses advanced DNA analysis to detect hidden, dormant or microscopic mould spores, helping identify contamination that a visual inspection might miss.
How does the testing process work?
We take dust samples from specific areas of your property using professional sampling equipment. The samples are analysed in a laboratory to identify mould species and produce an ERMI score that measures the mould burden within your property.
What happens if the results show high mould levels?
Your report provides a clear ERMI score that helps guide remediation recommendations. We combine these results with professional moisture mapping to identify the source of dampness and help prevent future mould growth.
Is this test suitable for all properties?
Yes, ERMI testing is suitable for both residential and commercial properties, particularly when there are concerns about mould contamination, following water damage, or when you want to assess indoor environmental conditions after remediation.
