Owner finds damage in the timber post-remediation after the re-installation of the Mdu Probes

This property is an absolute classic of how NOT to design, a property that could easily have wonderful large eaves, instead has almost complete internal gutter system right the way around the perimeter, and a cladding installer has been asked to quote for the job of installing it (2009).

This is a classic example of why the Mdu Probe System is so helpful in determining damage. An Mdu Probe was installed into the bottom plate of a wall, and damage was found inside it as well as an elevated moisture content. The gib was then removed and the surface of the timber shows no evidence of the decay inside the timber. Had the Mdu Probe not been installed in this area, then a ‘visual inspection’ by removing gib and examining the timber surface would have given the impression that the area was perfectly ok when in fact it was hiding damage and high moisture.
This phenomenon is often repeated in many instances and gives insight as why many structural issues are missed by structural and moisture inspections carried out internally, through the gib or non-invasively.

1998 plaster house repainted in 2006?, has bands around windows, rain heads, parapets capped, decks, metal roof, gutter stop ends resealed 2006?, louver aluminum windows. VCR report – control probe ‘C’, one only ‘D’, many ‘C’ with only 2 worse than control. MC reading March 2009, 2 red, many in yellow and orange, bulk upstairs green. Predict that many of VCR ‘C’ are historically construction or delivery sapstain or if early decay may have abated and done no further damage. Consider this to ID 971 which is a new home (Sept 2008) with construction moisture and worse VCR gradings. Perhaps ID 971 will dry out and resemble ID 1139 in 10 years time? Perhaps winter construction features in VCR – which may later be misconstrued by weathertightness experts. Interestingly the Timber Strength of ID 1139 is around 30\% on average stronger than ID 971. This may show timber naturally seasoning and becoming stiffer over time. This may alleviate concerns about low strength graded timber finding its way into homes – and not immediately showing up as deformations etc#971 , #1139
John installed the Mdu Probe System into their new home as a means to speed their Code of Compliance process

Barry Gray came to Moisture Detection after first using other methods of house inspection. Using Mdu Probes he was able to accurately track the progress and ascertain the success of repairs he has made on the back of a WHRS report.
Dear MDC, Please find attached the latest moisture readings for our house. The probes marked with * are in areas where I have carried out further repairs, i.e. cutting away the plaster below where the Hardibacker finishes. You will notice that there has been an average 34\% reduction in the moisture readings for the repaired areas versus 5\% for areas that had been repaired prior to the insertion of the probes or areas yet to be repaired. Also, I was a bit disappointed with Anne Gibson’s article of the 18/1/05. I felt it lacked any input from the people that have installed the MDU probes and the reasons why they chose to do so. This may have been because nobody wanted to talk to her or they all wanted to remain anonymous. She certainly didn’t approach me for comment. Anyway, I have e-mailed the above figures to her along with my opinions on her article. In summary, I outlined my disappointment with the WHRS and the industry that has been created around the pursuit and defense of claims that in many instances have no chance of success. I disputed the comments of ……………. who I consider a hired gun, who changes his opinion depending on whether he is being paid by a homeowner pursuing a claim or a builder defending one. I also took issue with ……………’s comment that the probes were not calibrated. In our case the readings obtained from the probes are consistent with my own readings and those of WHRS. I explained that I considered that the MDU probes were cost effective and as far as I was concerned, offered the most constructive method of determining if my repairs were effective or not.

Steven Brown approached Moisture Detection because of trouble gaining a Code of Compliance Certificate from the Auckland City Council. MDC installed the Mdu System and after submitting the Mdu House Report to Auckland City Council, Steven gain his sought-after compliance. He has undertaken an agreement to have on-going monitoring of his home, and is rewarded with peace of mind about the condition of his house.
Tarsha needed a Code of Compliance for her home and was told she may have to reclad. The Mdu System assisted Council to re-assess the house and the house was granted a CCC
