Termites that attack houses are almost exclusively subterranean species that need to maintain very specific environmental requirements. Termites, after entering a dwelling rapidly humidify the galleries they inhabit and actively regulate the temperature. Higher quality thermal imaging cameras are used to detect this temperature differential. The TESTO 885-2, for example, has suitable resolution and thermal range to detect even very minor temperature differences.

Depending on atmospheric conditions, termite infestations can appear as hot in winter or cold in summer, spring and autumn. Termites can go undetected on the concealed wall framing for months, causing significant structural damage. Australians spend millions of dollars each year treating termites and repairing the resultant damage. Detecting a termite infestation before serious damage is caused can potentially save homeowners thousands of dollars.

We use the thermal imaging camera to detect small temperature differences caused by termites, leaks, moisture issues, rodents or insulation anomalies. Thermal imaging cameras can find low levels of termite infestations, often much earlier than their presence can be detected using conventional methods such as tapping tools and moisture meters.

Our services also include pre-purchase building inspections and diagnosing building faults such as leaking showers and roofs, moisture and waterproofing issues, and insulation irregularities.

Used properly in conjunction with other tools, and most importantly with a thorough visual inspection, we can detect far more using thermal imaging than can be found by visual inspection alone, however the following pre-inspection preparation will dramatically enhance what can be detected.

  • Remove other heat sources from the house – dogs, cats and other pets will cause heat deviations.
  • Turn off any unnecessary appliances – even a personal computer running will cause a heat deviation in a nearby wall. Appliances in standby also create heat deviations.
  • Turn off any air conditioners or heaters. We want a stable ambient temperature in the building.
  • Make access to all the walls – (as full and free as possible) the more of the walls we can see the more we can detect.
  • Provide any previous inspection reports carried out on the house or any history of previous treatments, or previous termite activity, where possible.
  • Ensure access to the property is arranged for a part of the day that is not too hot. During summer the morning is best, however in cooler weather termites may not be active early in the morning, so the afternoon may be better.
