Inspect It >> provides estimated costings on Building Inspection Reports, however there are few items you need to be familiar with, before your order.
If the Building Inspection Report includes any estimate costings it is important to remember that the costs included within the defect summary are merely opinions of possible costs that could be encountered, remember, this is a visual inspection only. These costs are based on the knowledge and experience of the inspector. The estimated costs are not a guarantee, nor a written quotation of rectification works for that particular defect.
The actual cost of the rectifcation of a given defect is ultimately dependant upon: the materials used, the standard of work carried out, and what a contractor is prepared to do the work for. For example a building inspector may give an estimate of $1,000. to rectify drummy tiles in the bathroom. The inspector only takes into account the rectification of the defect viewable via the visual inspection and will not consider: you using an expensive tile, that you have used a particularly expensive contractor, or that there could be additional damage within the wall cavity. All of which will need to be taken into account when assessing the actual cost of rectification.
It is recommended in all instances that multiple independent quotes be sourced prior to any rectification works being carried out. Prices can vary dramatically.
Have a look at our sample Building Inspection Report with estimated costs of repairs, they are a real advantage as they provide a good idea as to the severity of a defect.

Reasonable access
Recently we have received calls regarding our inspectors and their reasonable access to various sub floor and roof void areas. Below is a guideline to where the inspector, in most cases, will not inspect. Only areas to which reasonable access is available will be inspected. The Australian Standard 4349.1 defines reasonable access as;
“Areas where safe, unobstructed access is provided and the minimum clearances specified are available, or where these clearances are not available, areas within the inspector’s unobstructed line of sight and within arms length. Reasonable access does not include removing screws and bolts to access covers.”
Being a visual inspection, reasonable access does not include the use of destructive or invasive inspection methods nor does it include cutting or making access traps or moving heavy furniture, floor coverings or stored goods. If at the time of inspection we are unable to gain access to particular area, further access can be gained through: making current access holes available, the cutting of access holes, or the movement of furniture. Typically this involves a letter of authority from the vendor allowing us to do so, showing they are aware the damage that may arise as we try to gain access into restricted areas. We recommend further access be gained to all inaccessible areas.
If you would like further information or have your own story on the issue please post a reply, call or email us.

Should you worry about asbestos?
Asbestos is the name for a group of very heat and chemical resistant fibrous minerals that are mixed into building materials. Asbestos can be found in floor and ceiling tiles, coatings, texturing materials and insulation. Only when materials containing asbestos are disturbed or when the fibers separate and become airborne are they a hazard to your health, which leads to the most common form of exposure, breathing in these asbestos fibers.
The body cannot breakdown or eliminate inhaled fibers and a slow buildup of scar-like tissue in the lungs (called asbestosis) can occur. Asbestosis has typically been observed in asbestos workers and asbestos is known to cause cancer. There are no symptoms of exposure such as coughing, sneezing or itching and therefore you cannot tell if asbestos is in the air or if you have inhaled it.
We receive many calls regarding asbestos, what it is, and if it is included in our pre-purchase inspections. The following statement comes directly from one of our reports on a property which contains asbestos;
‘Although we are not qualified in the detection of asbestos material, this item appears to contain asbestos. Asbestos material should not be disturbed or damaged and should only be removed or altered by a licensed asbestos removal contractor. Asbestos is hazardous to health and should be sealed to prevent exposure. Recommend an analysis by a qualified removal expert be conducted of these materials to confirm the amount and importance of the asbestos present, and the cost to seal or remove.’
All of us here recommend any owner or potential purchaser who comes across this statement in a pre-purchase or vendor inspection obtain an asbestos audit.
Essentially asbestos is not a deal breaker however it is important to seek advice from a licensed asbestos auditor, who can tell you: the amount present, if there are immediate concerns and who will put it into perspective. If you have any questions or your own experience, please post a comment or send us an email.

Is dampness a deal destroyer?
Not necessarily, it is important to speak to your consultant and make sure all defects are put in perspective. Most defects are easily rectified, in isolated areas, and may be typical considering the buildings type and age. It is important not to jump to the worst conclusion.
Dampness affects not only aesthetic appeal but also structural integrity. Tell-tale signs of dampness are: mould spots on walls and timber work, blistered or stained paintwork, soft or crumbling plaster, brickwork or stone. Peeling wallpapers and visible salt deposits on wall surfaces are also indicators.
Brick and masonry absorb water, so must be sealed off from contact with moisture and moisture bearing substances like soil. If not, water will rise in the walls causing dampness. When the dampness evaporates it creates cold clammy conditions in solid brick houses and leaves behind the corrosive salts.
There are different types of dampness:
Rising damp - ground moisture being absorbed into masonry walls.
Horizontal penetrating damp - water seeps through defective brick walls or incomplete mortar joints.
Condensation - inadequate ventilation.
Falling damp - defective roofing and plumbing equipment.
Damp-proof courses were originally formed by layers of slate, asphalt or bituminous felt in cement. The location is approximately 150mm above ground level but below floor level. Today the most commonly used materials are bitumen-coated copper or aluminum, heavy-duty polythene is sometimes used. Different types of methods can be used for the cure of damp; installation of a physical damp course has been looked upon as the most effective cure for rising damp. Chemical injection has been used with varying degrees of success as well as chemical impregnation.
We hope this has given you a better understanding of dampness, and as always, please send us a photo or tell us your story if you have one. Call or email us to obtain further information, or a second opinion.

Delay over dampness??
Without a doubt one of the most commonly asked questions we receive is…
“should we purchase a home with rising damp?”
Yes the situation can be rectified, and no you don't necessarily need to delay or pullout of a purchase. In tomorrows post we will explain the cause and various rectification methods, we will also try to include some photos. Of course the severity of the dampness and the solutions required are individual to the home you wish to purchase. It’s a good idea to talk to the consultant and see if it is minor, typical or major for a building of its type and age.
Keep a look-out for tomorrows post. As always you can ask us a question by calling or emailing us.

Anobium Borers
Anobium borers; also called Furniture Beetles or, Anobium punctatum are often sighted while conducting our Pre-purchase Pest Inspections, we receive many calls from people wondering just what they are, and the kind of damage they cause. Here is some information that may assist you.
Assuming the report was commissioned as a pre-purchase inspection, you can expect to see wording along the lines of: Yes - Anobium borer damage was noted to the following timber(s)/area(s). Without destruction of the timbers it is not possible to determine whether activity exists or the extent of timber damage within.
The report should then list the areas and the severity of the timber damage. Depending on the location it may not be possible to chemically treat the timbers. If borer activity is present or if the level of damage is considered significant, timber replacement may be necessary.
The borer is a major pest species and attacks the sapwood of softwood species of timber particularly in older houses with damp flooring timbers. The beetle is also often found in furniture of various timbers.
The tell tale signs are the small exit holes and dust emitted from the exit holes in the timber. Severely infested timber has a honeycombed appearance and the frass is fine and gritty. The larva cause most of the damage.
Increasingly in most minor cases Permethrin insecticide is used to treat the beetle due to its low toxicity and its ability to penetrate into the timber grain. The Permethrin insecticide application will kill the adult beetle as it emerges from the timber, provided the beetle has contact with the treated surface. In moderate infestations, the application of a registered insecticide to the underside of the flooring on an annual basis over a three year period to cover the life cycle of the Anobium borer. In severe cases, replacement of all damaged and infested timber with highly resistant or chemically treated timber is recommended. Improvements in subfloor ventilation may also be recommended.
We hope this has given you a better understanding of the Anobium Borer, as always you can call or email us to obtain further information.

Description of Delignification
For purchasers of older homes, typically around areas of either high salt air areas or high industrial fallout areas (eg. motor vehicle gases) this post is a MUST READ!
Delignification or Defibration or it can also be known as Chemical Delignification damage, is most commonly found, but not limited to timber used as roof tile battens of buildings that are located in close proximity to the sea, large chemical factories or major roads. The term describes deterioration in which the lignin in timber is damaged by airborne chemicals. Lignin is the natural glue that holds the fibres of wood together. When the lignin is broken down or damaged the fibres then detach from each other creating a visible hairy surface, the delignification progresses causes the timber section to become weakened. Chemical Delignification is regarded as a structural pest of timber in service.
Chemical delignification generally will not occur to timbers in service that are sealed, painted or well oiled as the lignin is protected. In advanced cases of chemical delignification then replacement of the timbers is needed. The cost of repair of the chemical delignification damage would need to be taken into account upon inspection.
Chemical Delignification may only occur after timbers have been exposed to airborne substances for a relatively long period of time. Upon reading an Inspection Report which contains evidence of delignification, apart from the costs involved, also consider the possibility that the air quality in the proposed area may be affected by chemicals. Health hazards may be present that could cause long term damage to a resident’s health.

Spalling Concrete
We often receive calls regarding Spalling Concrete when the defect appears in Building Inspection Reports. Below is a brief explanation of the causes, effects and rectification needed to overcome the problem.
Spalling concrete, most commonly referred to as concrete cancer and is largely due to a natural deterioration process called carbonation. Carbon dioxide in the air diffuses into the concrete and reacts with the alkalis in it. The concrete becomes carbonated and this allows the embedded steel bars to corrode. The bulging and cracking of the surrounding concrete is caused by the force exerted due to the expanding steel bars. The spalling concrete should be repaired as soon as possible before the steel bars corrode further and damage larger areas. The early treatment of spalling concrete will not only cause less damage to your building, but will be less expensive to repair.
Spalling concrete is rectified by, removing the Spalled Concrete areas to expose the steel bars, ensuring that all surfaces of the steel bars are exposed and can be treated, then cleaning, de-scaling and the application of a primer/sealer as a rust inhibitor to the exposed Steel Bars. The aim is to prevent oxygen and moisture diffusion, a good coating of the correct primer/sealer will slow down the carbonation process and minimise the ingress of oxygen and moisture into the concrete, helping to prevent the corrosion. Immediately sealing any cracks in the building as well as having the building painted regularly can reduce the occurrence of this problem.
