Termite
Inspections
Environpest termite inspections (both for pre-purchase and annual inspections) are in accordance with Australian Standard 4349.3, and include visual inspection of all accessible timbers, including accessible roof void timbers. A moisture meter is used, and if an area of high moisture that cannot be readily explained is discovered, the area is checked with Termatrac. (Termatrac allows us to look inside the wall by microwave to see if there is any movement) Our inspections are carried out by Mark or suitably qualified technicians under Mark's guidance.
If movement is discovered, then a more invasive inspection
(borescope) is usually recommended (Owner's permission required). If no movement
is found, then the moisture can be as a result of poor damp course installation
in a low brick sill, or a leaking shower. We'll typically refer you to the
appropriate people for advice on these issues if required. Thermographic
survey or thermal imaging
is also an
option. If a timber pest
inspector doesn’t use a moisture meter, or is reluctant to enter an accessible
roof
void,
please don't hesitate to find yourself another inspector.
Environpest
inspections also include
assessment of the expected protection periods of the termite protection
installed to the home, and further treatment recommendations are
only
reached on the basis of termite activity to the home, or significant risk.
Termites in a fence separated from the home, or in the yard next door are no
indicators that the termite barriers of the home have been breached.
In the course of an inspection, something else we try to advise on is how the home is constructed, and if the home is constructed of termite resistant or termite susceptible framing. Earlier homes (including most weatherboard homes) were usually built using hardwood framing, and most hardwoods are regarded as being termite resistant. Most modern homes are framed in radiata pine, which is termite susceptible framing. Brick homes can be a concern, with most people not realising that with most modern brick homes, the bricks the bricks serve no structural purpose. They are only a wall cladding and could just as readily be weatherboards or fibro. The structural integrity of most modern brick homes is the timber framing behind. The consequences of termite resistant and termite susceptible framing is that with termite resistant framed homes, if termites occur, damage will normally (not always) be confined to trim timbers which are comparatively easy to replace, before structural damage occurs. With termite susceptible framed homes, if termites occur, they can attack the structural framing of the home as readily as they can attack the trims, and serious structural damage can occur. Termite resistant framing also includes cypress pine, and LOSP treated timber.
With
an average home, an inspection will take about 1 to 1½ hours, and a full written
report is provided of our inspections
Termite inspections are generally carried out on an annual basis, but more frequent inspections can be recommended by the Australian Standards where conducive conditions are found. With termites widely regarded as requiring 12 months to do serious economic damage, the annual inspections are a balance between inspecting too often for our clients' hip pockets, and inspecting not often enough that serious structural damage can occur between inspections.
Current charges for most homes in the Brisbane metropolitan area are $220.00 for an initial inspection on a home owner's own home, and $198.00 for the repeat inspections. Our charge for a pre-purchase inspection is $264.00 for a normal sized home. If you look at what we include within our inspections without seeking additional monies partway through our inspection (some are starting inspections, and when moisture is found, suggesting you spend $60.00 extra to have it checked by Termatrac), and how we reach our treatment conclusions, we're extremely good value for money in the long term. Where larger or commercial properties are involved, our charges rise, but we tend to work on the basis of being fair and reasonable.
Weep holes can be an issue to some, and for more information on this issue, please visit our weep holes page.
It
is also extremely important to note that as of the 1st of January, 2001,
all timber pest inspectors, or their companies must be registered with the
Building Services Authority. You can do an on-line licence check at www.bsa.qld.gov.au, and Environpest hold BSA licence # 714223.
In 2004, the BSA has upgraded the licence check pretty substantially, and it's
well worth checking out if you're looking for an inspector, or a builder. A tip
is that once you've gotten to a licensee's particulars, there is a button that
says "Create
Licensee's Full History". Click on that (even
though it doesn't react to the mouse over the button), and it'll take you to
another page with a lot more information.
Public liability and professional indemnity insurances are an important part of professional inspection, providing security for the consumer. The Building Services Authority is apparently removing the insurance requirement for pre-purchase timber pest and building inspection services. For more information, visit our Insurance page.
If you are buying a home, it is very important that you have a building inspection as well as a timber pest inspection. There are some who provide both services, but to our view, building and timber pest inspections are two separate entities, and few seem to be able to do both properly. There are a few building inspectors we have found to be thorough, and we have no hesitation in recommending them. If you're looking for a building inspector, please visit our Preferred Building Inspectors page.
In some inspections there can be issues found that should be referred to the Building Services Authority for adjudication. We are experienced in this area, and for more information, please visit our BSA Case Histories Page. Where additional reporting is required say for litigation or Building Services Authority investigation, additional charges apply, and include digital video reporting.
Another inspection technique we have found extremely useful is thermographic survey or thermal imaging. These are carried out using an infra red camera from Termicam. Charges are typically $400.00 for a home, and this inspection technique is especially effective in establishing termite entry points, or inspecting large areas or buildings quickly. Most homes can be adequately and appropriately inspected by a competent timber pest inspector using the techniques described above, but in some instances where termites are particularly persistent, or if the termite entry point needs to be specifically found, then thermal imaging can be a useful tool.
