New Home with horrible roof detailing – haven’t learnt the leaky building lesson

New Home with horrible roof detailing – the industry hasn’t learnt the leaky building lesson

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).

Looks like good timber above, rotten on the inside

Looks like good timber above, but it is rotten on the inside

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.

10 year old house and new house have same damage

10 year old house and new house have same damage

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

Repairs monitored and Peace of Mind found

Repairs monitored and Peace of Mind found

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. Regards Barry Gray

House gains CCC after long battle

House finally gains CCC after long battle

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.

Dear MDC Just a note to say thank you for the service provided to me by your company. As you are aware I had an application in to the Auckland City Council for code of compliance on my house. One of the requirements of the application being to provide a weather tightness report. Subsequent to having your probes inserted through the dwelling and the analyses of moisture I am pleased to advise you that I have been back to the Council and had my Code of Compliance Certificate issued. Obviously there is more to compliance than moisture reports, but I am sure being able to present the facts made the compliance process easier for council while they carried out their own inspections and investigation. I would recomment to anyone constructing a new house or purchasing an existing dwelling with a monolithic style cladding system to install the Mdu Probe System. The information in the report presented will (as in my case) put the owners mind at rest as to the integrity of their home or identify areas of concern that should or could be addressed. Once again, thank you for your service. Kind regards STEVEN D BROWN

House gains CCC despite having non-acceptable solutions

House gains CCC despite having “non-acceptable” solutions

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

Dear Moisture Detection Thankyou for your moisture detection report provided to us late last year. We have now forwarded this report to council and our code of compliance certificate is in the process of being issued. We were totally distraught upon having our council final inspection to learn that the council was not going to approve the cladding component of our dream home. We also believed councils stance that the house may fall into the ‘leaky home’ category to be unjustified. The report we received from Moisture Detection Company Limited both confirmed our belief that our home was well constructed and waterproof, and also demonstrated this to council. Upon receipt of the report council passed the cladding component of our home within two weeks. We are also grateful for the peace of mind we now have knowing that our home is water-tight. The Mdu Probe System has given us the means to address any water-tightness issues that may arise as our home gets older before any significant damage or deterioration occurs. Your system enabled us to achieve a mutually beneficial compromise with the council, with minimal cost and anxiety. Many thanks for all your assistance. Kind regards, Tarsha Hazleman
