Non-Invasive Moisture Inspection (Moisture Scan/Test)
PLEASE READ CAREFULLY
Non-Invasive Internal Moisture Scan/Test is based on non-invasive moisture measurements and performed according to attached Standard Procedure.
Scan/ test results reflect the current condition of the areas/elements tested on the particular day of inspection.
The report is preliminary and superficial only and although it is indicative of the current condition, it should not be used to base any purchase decisions on. A more comprehensive house inspection and report is recommended.
LIMITATIONS OF LIABILITY
The client understands and agrees that any claim against the accuracy of the report, in the form of errors or omissions is limited to the failure on the part of the inspector to follow the 2020 House Inspection Services Standard Procedure.
Because this is a limited inspection, we can make no guarantee, expressed or implied, that our observations and random moisture readings offer conclusive evidence that no installation or moisture problems exist, or that problems found are all-inclusive. It is a no way an assessment of a compliance of any building codes or regulations and is not a guarantee that no moisture issues exist or that issues will not develop in future.
This inspection company, its employees, and any divisions shall not be liable for non-visual defects, unseen defects, unspecified defects or hidden damage and conditions existing on the subject property and hereby disclaims any liability or responsibility thereof. All parties concerned agree to hold harmless and indemnify this inspection company involving any liabilities that may result.
Please note that dry weather can affect a moisture inspection as less moisture will remain in the structure. A wet season or after rain will produce a more accurate result. A non-invasive inspection has the limitation of only being able to read into any timber framed wall to the depth of 5-40 mm depending on the density of the material being tested, construction and the type of meter used (TRAMEX up to 30mm; Trotec 650 up to 40mm* as per Specifications). This does mean that if there is some dampness on the outside of the wall framing and it has not leaked into the wall far enough towards the above dimension then it may not be discovered.
The non-invasive moisture meters will not detect or measure moisture through any electrically conductive materials including but not limited by metal sheeting or cladding, black EPDM roofing, butyl roofing, some rubberised waterproofing, aluminum siding or wet surfaces, aluminium foil.
Decayed timber (dry) is not detected by non-invasive moisture meter, visual inspection with timber strength testing, collecting “shavings” and further investigation is recommended.
In some cases a vendor may disguise a problem by drying affected areas prior the inspection, installing new lining, painting surfaces over or placing the furniture in front of problematic areas. As our inspection is non-invasive and is of a visual nature, we can not move the vendor’s furniture or belongings there are some limitations in inspections and we can’t be held liable for concealed or disguised problems. Obtaining a vendor statement about the house's moisture condition and a final re-inspection before settlement when the house is empty is highly recommended. Immediate notification about any problems to your solicitor and inspector is strongly advised.

TESTING/ SCANNING METHOD
Testing Drywall, Ceramic tiles and other wall and floor covering. Using non-invasive moisture meters on materials other than exposed timber is not a reliable indication of the amount of moisture below the surface. As calibration is not practical because of the variation in composition of these types of construction, tests are carried out on a comparative basis selecting the most appropriate scale, and readings are taken from the 0 to 100 (Tramex); 0-160 (Trotec) comparative scale on the meter dial (not %%). The information gained can only be useful in comparative terms, not in absolute terms – when readings in known dry areas are low but are higher in a suspect location of similar construction, there may be elevated moisture levels.
