Dust sample test

Our analysis of settled dust is ideal for screening for concealed mould.

Customers collect dust from a flat surface such as a door frame using a swab. The sample is then shipped to HouseTest's laboratory for analysis.

Taking a sample is a simple process that requires no specialist training or equipment.

This is the most frequently used of HouseTest's DNA analyses and is used for screening a building for concealed mould growth. The dust test can be used by specialists and private individuals alike.

Air sample test

HouseTest can also analyse air samples when screening a building for concealed mould. Air samples can either be taken using the activated air sampling method or using passive air sampling.

Activated air sampling involves mechanically disturbing the air before taking the sample. HouseTest rates the results of activated air samples on their A-F scale. HouseTest does not rate passive air samples, which also require an outdoor reference sample.

Air samples can only be taken by specialists.

Surface test for visible mould

HouseTest's surface test identifies the species composition of visible mould growth on the basis of swabs taken directly from a microbiological growth. We only offer this kind of test to professionals.

Clean-up test

HouseTest has also developed a clean-up test.

The clean-up test evaluates whether a final clean-up following mould remediation work has been successful. Please note that it is the final clean-up - and not the mould remediation itself - that HouseTest evaluates. We evaluate the data on the basis of predetermined criteria, which means that we can objectively assess the success or otherwise of the cleaning work.

The clean-up test uses activated air samples, which can only be taken by professionals.

How dangerous are moulds?

Certain types of mould release toxins known as mycotoxins, which make mould-infested homes a health hazard.
