Moisture and Mould Assessment
The Key to Mould is Moisture!
Mould’s favourite food are water-damaged cellulose materials such as timber, MDF, plywood, chipboard, paper products like cardboard and books, plasterboard, clothes, furnishings, insulation, wallpaper, glues and dust...
However, without water (moisture) mould spores, which are present on all surfaces, may remain dormant for many years and will thrive when they are given water.
Moisture events such as floods, plumbing leaks, roof leaks as well as subfloor moisture, condensation and inadequate ventilation may all result in water-damage to building materials and eventually lead to mould growth and material decay accompanied by visible or non-detectable signs and odours. Once a building material is wet for 48 hours, microbes may begin to proliferate and the risk of mould growth is elevated.
People living in water-damaged homes have been known to experience a variety of allergic and inflammatory reactions including skin irritations and eczema, lung problems like asthma, bronchitis, cold and flu-like symptoms, hayfever and pneumonia (Antova et al 2008; Fisk et al 2010; Mendell et al 2011).
Water-damaged homes typically not only have mould and their by-products, but also elevated bacterial loads, microbial chemicals, particulates, house dust mites as well as pests like cockroaches, rodents and termites, all of which in their own accord, can contribute to adverse health effects (Bijlsma 2018).
Those who are more environmentally sensitive will react to this complex stew of inflammagens and toxins and may experience a variety of symptoms including headaches, brain fog, fatigue, muscle aches and persistent joint pains, sleep disturbances, sensitivity to chemicals and many others. Do you suspect that your home is water-damaged or affected by mould?
What does it involve?
The aim of this assessment is to identify the source(s) of moisture, determine the extent of moisture ingress that supports microbial growth, and to establish the spread of fungal particulate from a source of active growth throughout the home.
To fully determine the extent of water damage and microbial contamination we use a range of investigative tools including thermal imaging cameras, thermo-hygrometers, moisture meters, indoor air quality meters and boroscopes.
Types of sampling that can be carried out:
Air Sampling (Mould Count/Culture and Identification to Genus)
Surface Sampling (Tape lifts, Bacteria swabs, Air-O-Cells, ATP)
Dust Sampling (ERMI Swiffer/ Vacuum and HERTSMI-2)
Destructive Sampling (bulk and cavity air)
What will you get?
An initial interview over the phone and an online questionnaire to be completed before site visit to determine goals of the assessment.
A comprehensive visual investigation of the site and building including moisture mapping and sampling (if determined necessary by scope and purpose of assessment).
A written report based on the findings of the assessment outlining observations, moisture mapping, interpretation of testing/ sampling results as well as conclusions on the state of the property and recommendations on how to remediate and address water-damaged building materials as well as prevent future issues associated with water-damaged building.
