Water Damage Technicians and Building Inspectors


Who we are and what we do

Building Science Ltd have been conducting inspections for Insurance Companies, Building Companies and Architects since 2013.

The Director has been involved in the insurance industry since 1990.

Building Science Ltd are Consulting Water Damage Technicians—and are internationally certified for this work.

The team comprises of members who have been / are certified builders, insurance assessors and water damage technicians.

The team have all worked together on different claims over the years, and we wanted to continue our professional association together in an environment where we could add value to people, looking to bring building science, and building skills to the purchase of their next homes.

Our mission is to inspect homes and detect building issues—then put those issues into context, so that buyers and sellers can understand what they need to do next, plus provide surety to banks by providing verifiable data for them to base their lending decisions on.

      What Building Science do differently is they:

  1. Test to insurance industry standards

  2. Test to IICRC S500

  3. Include Thermal Imaging and Moisture Survey as standard in each inspection

  4. Carry technician level quality testing equipment to perform moisture surveys on each inspection

  5. Use qualified Water Damage Technicians to comment on moisture issues

  6. Have the training and experience to create effective remediation plans for water-damaged buildings.


Building Science Research & Development


While it's all very well to go and make comments, on building issues, as impartial assessor's, we made a decision a few years back to get our hands wet, and get involved in developing solutions to solve some of the problems our clients face.

Research and Development projects completed and to market


1. Immunodiagnostic Onsite Test Kit for Brown Rot

Building Science is partnering with the microbiologist developer to bring this patented product to themarket. It's an onsite test, that allows a building inspector to test wood samples on site, and determine the   presence of incipient brown rot, at a stage, before it's even present to the eye.

Billions of dollars are spent annually to replace wood products destroyed by wood decay fungi.  Early detection  of wood destroying fungi is the key to:

  •  prolong the service life of wood

  •  prevent unnecessary replacement

  •  ensure that all infected wood is replaced or remedially treated to prevent recurrence of decay

    The immunodiagnostic wood decay test is a rapid, inexpensive, and accurate way to determine if fungal decay is present in wood. The test can be used by inspectors, mill companies, structural engineers and woodworkers in a variety of applications:

  •  Building inspections

  •  Historical restorations

  •  Utility pole inspections

  •  Structural maintenance programs (e.g. bridge decks, piers, railway ties, wooden aircraft  frames)

  •  Response to warranty inquiries

  •  Testing the efficacy of new preservatives

  •  Check that repairs are complete, thorough, and necessary

  •  Ensure that the grade and quality of wood have not been compromised by decay fungi

    This immunodiagnostic wood decay test is a one-step test that uses two antibodies to test for decay fungi. One antibody is conjugated with latex particles and another fungal specific antibody is immobilised on a test strip.

    Wood shavings are soaked in an extraction fluid for 2 hours. The extracted sample is added to the sample window of a test cassette. If fungal antigen is present in the extracted sample, the antigen will bind to the latex conjugate and form a fungal antigen conjugate complex. As the complex migrates forward on the test strip, the immobilised fungal specific antibody will bind the conjugate complex. If fungal antigen is present in the sample, a blue band will remain in the test cassette window, indicating a positive result.

2. CodeMarked Survey Standard for Monolithic Buildings for Moisture Intrusion

The test standard is currently being peer reviewed as part of the CodeMark process.  It has been designed to bring a clearly defined set of test standards to home and moisture inspections.  

The CodeMark will be made freely available to all building inspectors, building consultants, building surveyors in NZ and Australia, in the interests of bringing one standard that all parties can test to.  

This CodeMarked Survey Standard will make it easier for homeowners, and real estate agents to understand the actual condition of buildings they are bringing to the market, and provide a common language and standard for inspectors to test to.

The CodeMarked Standard is developed from the principles and standards recommended in IICRC / ANSI Standard S500, which has been the document the international insurance industry has used as the Reference Guide for Professional Water Damage Restoration since the 1970's.

Status:  CodeMark Achieved - In the market.

3. Codemarked System for the Testing, Remediation, Protection and verification of PLaster Buildings.

Building Science Ltd, has been involved in the creation of the Liquid Cladding System.  Many individual homes and multi-storey apartments have already used the system to restore and protect their external membranes.

Status:  In the market / CodeMark Achieved


4. IN wall Cavity wi-fi moisture sensor system

Taking the technology and experience from the insurance focused water restoration industry, Building Science have worked with a Silicon Valley tech company to bring to the market, wi-fi based, in wall, moisture sensors, that use proprietary algorithms to calculate and monitor:

  • Moisture entry

  • Expected lifespan of interior framing

  • Potential for mould growth

  • Equilibrium Moisture Content of internal framing

Status: In the market / installed in dozens of buildings throughout NZ
