Pre-Purchase Building Inspections

What Are Pre-Purchase Inspections?

Understanding what pre-purchase inspections are, whether you need one and who to trust to deliver it can save you (or cost you) tens of thousands of dollars. At Perth Building Inspector our trusted pre-purchase inspections can be carried our professionally, quickly and will provide you with peace of mind. 

A Pre Purchase Inspection is the primary service we at Perth Building Inspector offer. It is a service that has been refined over 25 years in the industry and has been developed into something we believe to be effective and imperative for any soon-to-be home-owners. In plain English, a property inspection is when our highly qualified inspector visits the property you wish to buy prior to the sale being carried through. The inspector gives the property a thorough assessment and checks to not only see that everything is in structurally sound, but that there are no potential problems that will sneak up on you after purchase. To the untrained eye, potential issues in the structural integrity of your home would be very difficult to pick up on, but through training and our experience as a very successful builder prior to the inspection field, we are well equipped to deal with any sort of situation.

We offer professional advice and provide comprehensive reports which are completed within 24 hours of the home inspection. After the inspection we are available for any questions you might have in relation to the inspection report.

3. Pre Purchase Timber Pest Inspection $175

Before you buy a house in Perth, you will need to have a timber pest inspection report prepared to make sure the property is not infested by termites or other timber pests including fungal decay and borers. 

The purpose of the Pre-purchase Timber Pest Inspection Report is to assist you – the Client – to identify and understand any Timber Pest issues observed at the time of inspection. Our inspector has successfully completed the Timber Pest Inspector course by Rapid Training Solutions and is therefore qualified to inspect for and report on Timber Pests. 

The inspection will include the following:

  • termite activity; past or present
  • past termite treatments where evidence is visible or paperwork is provided
  • areas of possible bridging or breaching of existing termite barrier
  • areas with excessive moisture
  • sub floor ventilation problems
  • areas & conditions conductive to infestation
  • areas where inspection was restricted or not possible
  • evidence of timber fungal decay damage
  • evidence of wood borer activity or damage
  • recommendations to help prevent future termite attack
  • possible safety hazards that may result from damage caused by timber pest

4. Practical Completion Inspection $495

The Practical Completion Inspection Report is the builders final ‘To Do’ list at handover. 

At this stage we will check:

  • Fixtures and fittings have been installed correctly
  • Appropriate sealing has been made to the wet areas
  • External treatments have been completed and the workmanship is acceptable
  • Paint finishes are of a quality standard,
  • All hardware is fitted and works including all doors & windows
  • All plumbing and electrical devices have been completed and functioning correctly
  • All cabinets are operational
  • Signs of poor workmanship
  • Roof structure and tie-down requirements



This inspection report will outline all defects that require attention. Each defect is marked with a coloured sticker for easy identification by the builder and the contractors. We perform a detailed inspection for every facet including the exterior and interior of the home. A sample of this report is available upon request.

5. Defects Liability Period Inspection $395

For contracts that fall within the threshold of $7,500 to $500,000 the builder is liable to make good, without additional cost, defects in the building work that have been notified in writing within 4 months of practical completion. 

The 4 months can be extended if agreed by both parties and it has been specified in the contract. The 4 months defects liability period applies from ‘practical completion’ which means brought to the stage where the home building work is completed except for any omissions or defects which do not prevent the home building work from being reasonably capable of being used for its intended purpose. 

Most new homeowners do not realise that the responsibility is on them to contact the builder in writing within the 4 months. Often this milestone goes past and the inspection never gets done. The inspection report will identify all maintenance issues which can then be sent to the builder. The importance of getting a complete inspection done cannot be emphasised enough. 

Homeowners that fail to get any building defects in writing are essentially responsible whether it was their fault or not. This can easily be avoided by having a proper structural inspection done to identify problematic areas. A sample of this report is available upon request.

6. Roof Frame Inspection $295

In Western Australia the common way to build a roof is by using a ‘conventional’ timber roof structure. It is a different type of construction to timber or steel roof trusses which are engineered and built in a factory. 

A conventional roof is built by a carpenter on site using timber that needs to be cut on site and fitted in its correct position. 

Additional to this are tie-down requirements that actually hold the roof down to the walls and foundations of the house so that the roof does not blow off in a storm or cyclone. So in this type of construction there is more room for mistakes to be made. 

The standards for roof construction are set out in Australian Standard 1684.2 and for new homes there are usually engineering drawings that detail how the roof of your new home will be constructed. 

Our inspector will use these plans to inspect what has been constructed and the report will itemise any area that does not comply with AS 1684.2 and the engineering plans.
