What Happens During a Building Inspection in Canberra? Your Step-by-Step Walkthrough

You’ve found a property you love in Canberra, had your offer accepted, and now the agent is asking if you want a building inspection. But what actually happens during those few hours? Will the inspector lift carpets? Check inside the roof? Tell you about that small crack in the wall?

A professional building inspection is thorough, methodical, and designed to uncover the true condition of a home beyond the fresh paint and polished floorboards. At Straight Up Inspections, we believe every buyer should understand the process before they invest. This guide walks you through exactly what takes place, area by area, so you can attend with confidence – or simply interpret your report like a pro.

Before the Inspection: What We Need From You

Once you book, we’ll confirm the property address, access arrangements, and any specific concerns you already have (e.g. a visible crack, recent renovation, or damp smell). We’ll also ask about the property type – detached house, townhouse, or apartment – as this dictates the scope.

If you’re buying, we strongly suggest attending the last 30–40 minutes of the inspection so we can walk you through our findings in person. But if you can’t make it, don’t worry – your report will be detailed and photo-rich.

Step 1: The Exterior – First Impressions Count

The inspection starts outside, because many structural issues begin where the building meets the ground and weather. Our licensed inspector will walk around the entire property, checking:

Roof Exterior

Condition of tiles, metal sheets, or colourbond
Gutters, downpipes, and flashings for rust, leaks, or blockages
Pointing and ridge capping on tiled roofs
Chimney condition and any visible sagging

Walls & Cladding

Brickwork for cracking (especially stepped cracking that may indicate foundation movement), mortar deterioration, and dampness
Rendered surfaces for delamination or cracking
Weatherboard or fibre cement for rot, warping, and paint failure
Expansion joints and articulation points

Balconies, Decks & Verandahs

Structural soundness, fastening, and any sign of movement
Balustrades and handrails – height, gap compliance, stability (safety hazard if non-compliant)
Water drainage and evidence of ponding

Site & Drainage

Surface water drainage away from the house (ponding water against footings is a defect red flag)
Retaining walls – leaning, cracking, or inadequate drainage
Paths, driveways, and steps for trip hazards

If we spot external issues like cracked brickwork or poor drainage, we’ll already be forming a mental map of what to check inside and underneath the house.

Step 2: The Subfloor – Going Under the House

In Canberra, many homes – especially older ones and those built on sloping blocks – have accessible subfloor areas. The inspector will enter the subfloor (wearing protective gear) and examine:

Stumps and piers – Are they sound, vertical, and free from rot or movement?
Bearers and joists – Any sagging, splitting, or evidence of previous repairs?
Timber condition – While we’re not pest inspectors, we note obvious timber pest damage, rot, or borers and flag it as a defect or risk observation so you can seek specialist advice.
Ventilation – Inadequate airflow causes condensation, mould, and timber decay. We’ll measure and note whether subfloor vents are sufficient.
Moisture – Damp soil, pooling water, or leaking pipes under the house are major contributors to structural issues over time.

This step alone can reveal the difference between a well-maintained home and a ticking time bomb. If the subfloor is inaccessible (concrete slab), we’ll note it and focus on related internal signs like floor unevenness.

Step 3: The Roof Void – What’s Above the Ceiling

Just like the subfloor, the roof void tells a story. Using a ladder, torch, and moisture meter, the inspector will access the manhole and check:

Roof framing (timber or steel) – Sagging, cracked rafters, cut or altered timbers (a sign of unapproved works), and rusted metal components.
Sarking and insulation – Presence, condition, and whether it’s correctly installed.
Water ingress – Stains on timbers or sarking that indicate a past or active roof leak.
Vermin or pest evidence – Rodent droppings, possum activity, or termite mud leads (noted as a risk, not a pest diagnosis).
Electrical hazards – Exposed wiring or DIY electrical work that could be dangerous.

In Canberra’s variable climate – hot summers, frosty winters, and occasional heavy storms – roof spaces take a battering. Many defects we find up here are invisible from ground level.

Step 4: The Interior – Room by Room

Once the exterior, subfloor, and roof void are done, we move inside. This is the part most buyers are familiar with, but a professional inspector sees beyond the cosmetic.

Walls & Ceilings

Cracking (hairline vs. structural – we differentiate)
Damp patches, mould, or bubbling paint (signs of moisture ingress)
Plasterboard nail pops, cornice separation, movement indicators

Floors

Unevenness or springiness (indicates subfloor issues)
Timber floor condition – cupping, gaps, rot
Tiles – drummy sounds (hollow beneath, indicating loose adhesion)

Doors & Windows

Alignment and operation (sticking doors can mean foundation movement)
Glass cracks or failed double glazing seals
Window flashings and any sign of water entry around frames

Wet Areas: Kitchen, Bathroom, Laundry

Visible plumbing leaks under sinks
Shower recess – we’ll check for cracked tiles, missing grout, and test for water leakage if possible
Exhaust fan operation (crucial for moisture control)
Toilet stability and flush function
Waterproofing defects (a common major defect in Canberra homes under 20 years old)

Safety Checks

Smoke alarms – presence, location, and operation test
Safety switches (RCDs) in the electrical switchboard
Staircase handrails, balustrades, and step consistency

We don’t move furniture or lift fixed carpets, but we’ll inspect all accessible surfaces thoroughly and note anything suspicious that may require further invasive investigation.

Step 5: The Report – Your Action Plan

Within 24 hours (often same day), you’ll receive a digital building inspection report. Here’s what it contains:

Summary of major defects – clear, plain-English descriptions of issues that affect safety or require significant repair
Minor defects – maintenance items and general wear and tear
Safety hazards – immediate risks flagged for attention
Photographic evidence – every defect is captured so you can see it, even if you didn’t attend
Recommendations – where applicable, advice to seek specialist quotes (e.g. structural engineer, plumber, pest inspector)

Importantly, we don’t use alarmist language or vague statements. You’ll know exactly what’s wrong, what caused it, and what you should do next.

Step 6: Your Next Move – Proceed, Negotiate, or Withdraw

Armed with the report, you’re in a strong position:

Proceed with confidence – If defects are minor, you can buy knowing you’re not inheriting a money pit.
Negotiate – Present the report to the seller and request a price reduction or repair of major defects. In private treaty sales, this is standard.
Walk away – If the property has major structural problems that aren’t feasible to fix, you can withdraw and continue your search. In Canberra’s market, another opportunity will come.

For new builds, the process is similar but has its own focus—see our recent post:

How Long Does It All Take?

For a typical 3–4 bedroom detached house in Canberra, the full inspection takes 1.5 to 2.5 hours. Apartments and townhouses may be quicker. Add more time if there are multiple decks, granny flats, or complex roof designs. We don’t rush—thoroughness is everything.

Straight Up Inspections is open 7 days, 9am–5pm, so we can schedule around your availability—even weekends.
