PESTY is well equipped to carry out invasive inspections.
The call for an invasive inspection is often referred to in Structural Pest Inspections or Property Inspections, for many whom carry out Pest Inspections this clause has been included in the documented report as a requirement by insurers and the like.
Very few of those who carry out Structural Pest Inspections actually carry out the Invasive Inspections, many simply have recommended further invasive inspection in a given report while not having the ability or the will to carry out such an inspection, quite often I get a call if I am willing to carry out such an inspection on their behalf - essentially this is a very good business practice by them as the responsibility shifts from the one who carried out the original report to the one who carries out the invasive inspection. Due to this apparent palming off of responsibility factor, I will generally not practice carrying out an invasive inspection where another inspector has carried out an inspection unless it is together with the original inspector.
PESTY is willing to carry out invasive inspections if given written permission to do so by the property owner, where we have made recommendation for an invasive inspection we would expect our clients to follow this recommendation and have us carry out an invasive inspection carried out where applicable.
Choosing to use the services of PESTY is a real benefit as we are able to carry out many types of inspections, including invasive inspections, we are licenced builders who can carry out the repairs to the building fabric when needed, we can carry out the necessary pest treatments as deemed necessary and we have some of the most advanced equipment in both the building and pest control industries.
When you consider employing a building & pest inspector it is in you best interest that they are capable of carrying out invasive inspections if needed as these often need to be carried out promptly prior to signing on the dotted line, we hope that our services will be your choice when considering building & pest inspections
PESTY has many years of experience in carrying out invasive inspections and has found that the most effective means of viewing the concealed timber framing is not by use of cameras but rather by removal of internal linings, in years gone by we used to drill openings the size of a 50 cent piece to insert cameras however this had many limitations, as an alternative, where permitted to do so, we would cut a strip of plasterboard out near the base of the internal walls, this type of mass plasterboard removal proved to be a nightmare to repair.
Today I choose to simply drill out 150mm diameter openings in the plasterboard where ever needed, it is quick, 150 mm hole is large enough for me to be able to see framing and/or put in a reasonable sized camera, it is just as easy if not easier to repair than a small hole. It is still messy and takes time to fully repair (as we need three visits to enable correct setting and sanding of repair) but it is considered to be the most efficient means for gaining the information we need as to the concealed structural damage.
* Image provides a view of a typical invasive inspection to view concealed timber wall framing when I drill the 150mm holes in the wall lining, the hole on the left side of the image has 150mm diameter wall section already replaced and ready for setting. The process is relatively neat and tidy, I do use a vacuum while carrying out invasive inspections so dust is absolutely minimal.
* Image shows how clearly the interior of a cavity can be viewed using good digital cameras inserted into a 150mm hole, I can also feel many of the timbers that are in arms reach.
Thermal imaging reveals areas of thermal inconsistencies where concealed termite damage is suspected, these areas once identified need a further, invasive inspection, Ausinspect chooses to use a 150mm hole saw for invasive inspections as this provides an ideal size for inspection of wall cavity and makes the repair easier and more likely to have a smooth finish once completely repaired, I drill the hole some 150mm above floor level, this gives me good vision of the bottom plate and studs.
Termite workings with active termites within the wall cavity are exposed by our invasive inspection techniques, this termite damage would not have been found had thermal imaging camera not been used.
The invasive inspection gives us a visual as to the termite activity, some idea as to the extent of termite damage and entry points, establishing termite entry points is critical, once entry points have been established a more effective control of the termites colony can be undertaken.
This image shows the termite mud trails within the wall cavities, also concerning is the mould and bacteria growth within the wall cavity that can potentially present a health hazard to humans, invasive inspection are very important to determine the true conditions of concealed areas, in this instance, condensation has been the primary moisture source that has attracted the termite activity into the structure.
Having sighted Thermal Inconsistencies at the time of the Pre-Purchase Inspection, the vendor was keen for the invasive inspection to be carried out immediately at his cost, I removed floor coverings, moved the furniture, drilled large holes for the purpose of invasive inspection, found the termite activity and the termite entry points, immediately initiated termite treatment by drilling hardened concrete surfaces at 150mm centres, applied chemical termiticides, sealed the holes, sealed the openings in walls for the purpose of invasive inspection and completed the entire treatment on the day so contracts could comfortably be exchanged without delay. Both the vendor and the prospective purchaser were very content with the service provided. When choosing Ausinspect you know we have the capability of servicing such a demanding job.
Ausinspect works efficiently, drilling of concrete surfaces for the injection of termiticides is accurate, soild areas are vacuumed as we go to minimise dust accumulation to surrounding areas, termiticides are applied immediately and the drilled holes are sealed upon completion of termiticides application to soils under the concrete slab.
The drilling of concrete surfaces for termiticides application is carried out so we penetrate the thickness of the concrete and any other hardened sub grade.
The moisture to the base of walls is minimal termiticides overspill at the time of chemical application, the overspill occurs where the pressure of the liquid termiticides enters the termite workings in the ground and spills out of the termite workings above ground.
The holes in the lined walls are sealed and a base coat of plaster is applied, the area is left tidy, no dust, minimal moisture that dries within a short time after treatment and sealed walls ready for final preparation prior to repainting of surfaces, once the floor coverings are re laid the evidence of the termite treatment can only be observed externally or to tiled surfaces.
Once the termite chemical treatment has been carried out, the property is reinspected some 4 weeks later to confirm the termites have been controlled, in this instance the property suffered a foul odor similar to rotten prawns two and a half weeks after the termite chemical treatment, the rotten prawn smell is the decay of thousands of dead termites. Had Ausinspect not used thermal imaging this termite damage would have been likely to have gone undetected as the only visible telltale signs were concealed by fixed cupboards against the wall.
It is our opinion that PESTY provides value by having the ability to inspect, treat and repair areas with termite damage at short notice.
