At the start of 2017, Taranaki House Inspections became part of TelferYoung (Taranaki) Limited. We have two qualified building surveyors offering services including building inspections, moisture testing and thermal imaging, meth testing and insulation reporting to meet Tenancy Act requirements.

Our Team

Nigel Purdie was the Managing Director of Taranaki House Inspections and is an Accredited Building Surveyor of the Building Officials Institute of New Zealand (BOINZ), plus a Certified Infrared Thermographer.  He now works for TelferYoung (Taranaki) Limited.

Nigel served his carpentry and joiner apprenticeship at Jones and Sandford in New Plymouth and then became self-employed as a Building Contractor in 1970.

After the construction of the Rarotongan Sunset Motel in 1986 he stayed on in the Cook Islands to manage the property until its sale in 1996.  Shortly after his return to New Zealand he became a private Building Inspector in the Auckland area.  Nigel’s return to Taranaki brings a wealth of building knowledge and experience in both the residential and commercial construction areas.

Taranaki House Inspections (now TelferYoung) has a combination of building and construction experience developed over 45 years in the industry.  This includes the latest technology with a thermal imaging camera.

Born and bred in Taranaki, Adam Boon has been with TelferYoung since 2005, after beginning his valuing career in Auckland, providing residential and commercial valuation services throughout Central and South Taranaki.  In more recent times Adam has become an Accredited Building Surveyor with BOINZ.

Adam served his carpentry apprenticeship at Ted Riddick Limited in New Plymouth and qualified in 1986, gaining Trade Certification the following year.  Adam spent nearly 20 years in the building industry gaining experience both here and overseas before embarking on a valuation career.  Being dual qualified has its advantages; and being part of the team here at TelferYoung we believe we can offer the very best in professional services Taranaki wide.

Our Inspections

+ Pre-purchase

Buying a home is possibly the biggest single transaction you will ever make. If you are contemplating this, it is wise to engage experts in their respective fields to help you through this process.

A building report investigates the structural integrity of the dwelling and advise you if there are any issues or defects with the dwelling. You can then negotiate with the vendor to have the defects rectified, accept the property with the defects known or cancel the agreement. It will also give you an idea of any renovation or upcoming maintenance required.
A pre-purchase inspection may also be a pre-requisite by insurance companies and banks. This is becoming more common due to changes in lending criteria and as a result of the Christchurch earthquake. These changes may have an impact on the type, age and condition of property that they will allow you to purchase. We recommend that you discuss these issues with your lender and insurance company prior to searching for your dream home.

+ Pre-sale

If the property you are selling is constructed with materials that may have potential issues, your agent may recommend that you obtain a building inspection report on the property. This helps to satisfy potential buyers of transparency between all parties and give you time to carry out any remedial work before listing your property.
An inspection may also be required by insurance companies and banks when you are considering changes to your contracts with either institution. This is becoming more common due to changes in banks’ lending criteria and insurance companies criteria.

+ Moisture Testing and Thermal Imaging

Moisture Testing
Moisture Testing uses either a capacitance and/or resistance moisture meter. These meters have a thin probe which is inserted into (usually) the Gib board of areas where the inspector suspects moisture ingress. Although the probe is thin, it will leave a small hole but is virtually undetectable afterwards. Readings of up to 18% are considered acceptable. However, if readings are higher than 18%, the inspector may recommend upgrading to a Thermal Imaging Report.

Thermal Imaging
TelferYoung (Taranaki) Limited has Taranaki’s only thermal imaging cameras.
Thermal imaging cameras indicate changes of temperature in the building materials. A decrease in temperature generally indicates retention of moisture in the material scanned.
Thermal imaging inspections will use this technology in areas prone to moisture ingress such as under windows, around doors or where a moisture meter has indicated high readings to highlight those areas to investigate further.

+ Cladding

This inspection/report looks only at the cladding to assess potential for moisture ingress and overall cladding integrity.

+ Unauthorised Works

Unauthorised work is work that has been undertaken without a Building Permit (Prior to 1992) or a Building Consent after 1992.
If a property looks to have unpermitted or unauthorised work, you have three options:

  • pull down the work (which requires a building consent) and rebuild;
  • for work carried out prior to 1992, engage Taranaki House Inspections to carry out an inspection and produce a report for Council. The report will discuss if the property is safe for occupancy, if it is sanitary (ie not offensive or likely to cause any health issues), any weather tightness issues, and has adequate drinkable water and sanitary services;
  • for work carried out after 1992, you can apply to Council for a Certificate of Acceptance of Unauthorised Work.
