If you’re buying a new home in Perth or surrounding areas, one often assumes everything will be perfect. You get new materials, modern standards, and a builder warranty if something goes wrong. However, new doesn’t always mean without defects. This is why an independent building inspection can be a smart move before handover.
A building inspection doesn’t assume your builder is careless. It’s simply an independent quality check before defects become a problem that costs you more money in the long run.
At IQ Construction, we’re comfortable with clients seeking independent inspections. A good inspection can support clearer communication, help prioritise genuine issues, and ensure everyone is aligned on what needs attention before you move in.
Why new homes in Perth can still have issues
Even reputable builders can end up with defects, when subcontractors, weather, supply changes, and scheduling pressure come into play. Here are some areas to look out for:
Reactive soils and site movement: Many Perth suburbs have clay or reactive soil profiles that can influence cracking and movement if site prep, drainage, or slab details aren’t right.
Coastal conditions: Salty air can accelerate corrosion if finishing details or fixings are not done correctly.
Heavy winter rain events: Stormwater management, roof plumbing, and overflow provisions matter as mistakes here can create big water ingress.
Construction sequencing pressure: When builds are pushed to meet deadlines, the risk of missed details increases.
When doing a building inspection, they normally check for:
An inspection is designed to identify visible defects and compliance issues that are accessible at the time of inspection. Commonly inspected items include:
- Roof space: framing, insulation placement, signs of leaks
- External envelope: brickwork, cladding, render, flashing details, weepholes, articulation joints
- Wet areas: bathrooms/laundry/kitchen such as waterproofing and detailing, seals, falls, fittings
- Doors/windows: operation, seals, water entry points
- Walls/ceilings/floors: cracks, finishing quality, unevenness
- Drainage and site works: surface water run-off, downpipes to stormwater, obvious drainage risks
- Safety items: handrails, stair issues, trip hazards (where relevant)
Are there limitations to inspections?
Inspectors can’t see through finished surfaces, so inspection regarding waterproofing behind tiles, internal wall framing, or concealed plumbing/electrical may be limited. The only way to truly inspect these areas is to conduct inspections during construction stages. A building inspection is not the same as a full engineering assessment.
If the home is under warranty, why do an inspection?
Builder warranties are helpful, but they’re not the same as preventing problems. A good inspection can:
- Catch issues early on, before they cause damage
- Provide a clear written record of concerns and evidence
- Reduce disputes
- Save you time and stress chasing fixes after you’ve moved in
The warranty is a safety net; inspection is risk reduction.
If you choose to have a building inspection, when do you do it?
Pre-purchase inspection
If you’re buying a newly built home from a builder/developer, an inspection before final commitment can help you:
- Identify defects before settlement
- Request rectification before you take ownership
- Reduce post-settlement disputes about what’s “new home settling” versus a defect
Pre-handover
This inspection is typically done when the builder says the home is practically complete, and you’re about to do handover.
As mentioned before, it’s much easier to have defects addressed before the handover when trades are still able to implement fixes opposed to needing to hire new trades again.
Stage inspections
For the most control, you can consider stage inspections where multiple inspections are made during specific stages of the building process such as:
- Slab/foundations stage
- Frame stage
- Lock-up stage
- Pre-lining (before plasterboard)
- Pre-handover
How to choose a good building inspector in Perth
It’s recommended that the inspector is:
- Independent: not affiliated with the builder or selling agent
- Experienced with WA construction styles: double brick, cavity brick, coastal detailing
- Provides a clear report: photos, defect descriptions, priority, recommended actions
- Insured: appropriate professional cover
- Willing to talk you through it: the best value often comes from the debrief
What to do if the report finds issues
- Prioritize defects: ask what’s urgent, what’s cosmetic, and what’s a “monitor” item.
- Raise items in writing with your builder/seller, referencing the report clearly.
- Request rectification before handover where possible.
- Re-inspect after rectification if the issues were significant.
- Keep everything documented: emails, photos, and versions of the report.
When working with IQ Construction, do you still need a building inspection?
We build to a high standard and follow a structured quality and compliance process. That said, an independent inspection is your choice, and many clients find it provides peace of mind, especially at pre-handover.
What IQ Construction already does as part of our process
Depending on the project, our typical build process includes:
- early site and design-stage checks to confirm constraints and planning considerations
- coordination with engineers and relevant certification professionals for required documentation and approvals
- structured site supervision and quality checkpoints during construction
- a guided handover process, including a practical walkthrough and completion documentation
Our perspective
If you choose to arrange an independent inspection:
- we encourage you to do it at the right time (often pre-handover, and/or staged if you want deeper checks)
- we prefer items to be raised clearly and early, so we can address legitimate concerns efficiently
Inspections aren’t about distrust, but clarity
A good building inspection is simply an independent snapshot of quality at a point in time. If you’re considering building with IQ Construction and want guidance on when an inspection is most useful for your type of project (custom build, knockdown-rebuild, extension, etc.), we’re happy to talk it through.
