MOISTURETESTS
Interior moisture levels were tested usinga Trotec® T650 moisture tester. It is an indicative test which directs moreinvasive testing should elevated or wet readings be returned. The only certain way to determine amoisture problem is through invasive inspection.
The reading scale is an exponential onefrom one to 200; with readings less than 50 considered dry, readings over 80considered wet and readings between 50 and 80 considered elevated. Wet andelevated readings require further investigation.
A total of 27 locations were chosen to takemoisture readings. The readings are typically taken about 100mm from the floor – the assumption being that if the wall isdamp the moisture will be near the bottom of the wall. Readings were also takenin the bottom of the vanity units, laundry tub cabinet, kitchen under sink andadjacent the toilet. The moisture readings were between 17.1 and 48.2 – these are in the dry range.
EXTERIOR
WallCladding (Minor defects)
The exterior cladding has had multiplecrack repairs completed down sheet joints of the substrate board. These are allnoticeable as the plaster finish differs, and the vertical lines show indifferent lights. There are also mitre join repairs around a window trim. Avertical sheet join crack remains in the exterior plaster on the back ofbedroom three.
There is a chip in the exterior plasternear the garage door & four exterior plaster cracks above window heads alsoremain.
Framing

Follow-up on the Leaky Homeproblem (我的想法)
Keywords:
face-fixedmonolithic claddings over untreated timber
Leaky Homecontributing factors (possibly) present at house:
· Plasterboard or Eterpan Cladding System
· (possibly) face-fixed (no cavity betweencladding and wooden frame)
· Claddingover (possibly) untreated timber
· Built between 1995-2004
Leaky Homecontributing factors not present at house:
· Mediterranean-Style Building: Flat roof, narroweaves, internal balcony
· Townhouse or apartment
Mitigating factors:
· Dry moisture reading
Aggravating factors:
· Inspection discovered existing wall claddingrepairs and minor cracks
Questions:
· Should I do further inspection, e.g. invasiveinspection to identify moisture problem?
· What’s the likelihoodof Leaky Home, or moisture problem in the future, compared to a typicalPrebbleton home built around the same time but with different types ofexterior? Will you feel safe to buy the home?
· Given the risk factors, what should be theprice adjustment from a typical Prebbleton home built around the same time butwith different types of exterior if I decide to buy the home anyways?
