Detailed Report with Photos
- Following our Building Construction Inspections Perth, our independent building inspector perth issue a detailed stage report for each stage that you request along with images relevant to stage we inspect. Our reports are customised for your property and will not be a standard report, after all how can it be?
- Each stage is treated independently as a separate report generated, this staged approach to construction inspections can save a huge amount of money and force builders to comply with NCC or National Construction Codes of Australia and put pressure on the builder to deliver a product fit for a paying and deserving customer. The small investment into Building Construction Inspections Perth always returns a higher quality build which in turn saves you tens of thousands of dollars in maintenance down the track.
- Building Construction Inspections Perth are intended to identify bad workmanship as well as errors in the NCC application to the build, it is NOT an opportunity to pick on the builder, and if the builder is doing the right thing (we all hope they will) the report may come back with a set of images stating that inspection was carried out in a satisfactory manner, giving you ultimate peace of mind.

Danielle and Francesca
So having Russell there with his understanding of the standard code of practices, it really made inspections less stressful , and we werenβt taken for a ride.
Thank you again for your help Russell and will defiantly have you on board next time we intend to build
These guys have been incredibly thorough. We bought a house and our agent recommended a different company who were not as thorough and said the house was fine. We then used WA Building Inspectors after we had some water damage, and a guy called Luke came out and went through everything with us step by step. He uncovered multiple issues and was super articulate on what was required.
The inspector Luke truly distinguished himself during the inspection. His expertise was evident, as he not only proved to be approachable and friendly but also demonstrated remarkable efficiency and thoroughness. Luke meticulously examined every aspect of the property, leaving no stone unturned. His professionalism shone through in his effective communication with the site supervisor, ensuring that any identified issues were clearly understood.
What sets WA Building Inspections apart is their exceptional value for money. In addition to receiving a comprehensive inspection, I was pleasantly surprised to receive a well-organised and easy-to-understand report on the same day. This quick turnaround allowed me to present the findings to my builder without any delay, which was invaluable in moving the project forward smoothly.
A heartfelt thank you is owed to the entire WA Building Inspections Perth team. From start to finish, they made the inspection process a hassle-free experience. Their professionalism and expertise were evident at every step, reflecting their dedication to their work.
Without a doubt, I will be relying on them for all my future inspections. They not only met but exceeded my expectations, providing the peace of mind I needed to proceed with confidence. I highly recommend their services to anyone seeking top-notch inspection services.
Not only did they refund that portion of the bill, they then came out and provided the scan as a complimentary service which was definitely above and beyond service. Thanks team, we'll be recommending you to all our friends and family.
Sarah in the office was always fast to schedule in times to check the key completion stages of the build for checking and Russel was always on point for the right standards and even just the minimum quality finish of works completed by all trades.
They were also flexible with a whole range of payment options.
Apologies for being blunt but if you are building or renovating these days it is a no brainer to have an inspector in your corner.
If I ever build again, I will be budgeting for a building inspector again with no hesitation.
He made time to get to the property before the auction and gave us a very detailed report on the propertyβs overall condition.
As a buyer, itβs given me the confidence to make an informed decision about the property.
Highly recommend Russel and the team.
They even had a drone service down to check roofing.
Highly highly recommended!!!
Thanks Russell & Sarah.
had done the inspection and report, for clarification on a couple of aspects. Russell was generous with his time and highly
knowledgeable. Thank you 😊
Marina
Russell helped identify a few issues with the property. He was super friendly, helpful and knowledgeable.
Thank you Russell

The inspector (Russell in our case) took the time to explain his findings in a manner even a dummy like me can understand!
I appreciated the way Russell and the team made the whole thing easy and would recommend them to anyone on the fence about who to use. Thanks!
Dean's professionalism is second- to-none & his comprehensive, concise, detailed & unbiased report has now been forwarded to my builder to make good some areas identified in my report, particularly with the roof which I am unable to climb & check out for myself.
I was also able to speak with Dean one evening, out of hours, who explained my report in detail in language that I could comprehend.
A huge "Thankyou " to everyone @ WA Building & Pest Inspections for your outstanding customer service.
Russell even took almost an hour during Saturday explain to us on all... all our enquiriesss ...
They have 5stars for a reasons, well informed, patients with us, what an ease dealing with them. No hesitation to refer them and hire them again..!
After he had finished inspecting the home he discussed, both with us and with the Builder appointed Site Supervisor, about the various aspects of the inspection in plain & clear terms. The discussion was a learning experience for us (the clients) as we learnt some essential things about building structures.
Inspection Report was detailed, specific and clear. Also, his T&Cs are acceptably good. Last but not least, his service is reasonably priced and is affordable. If asked I will definitely recommend him to my friends and I am confident they will thank me for recommending Russell & WA Building Inspections.
My report was very comprehensive.
I personally would use WA building inspections again.
Very thoughtful and easy to correspond with.
