Cracks, leaks and structural soundness in Mickleham rentals

The structural soundness standard asks for a home that is sound and weatherproof. What that means on Mickleham's basalt clay and how we assess it.

Mickleham 3064 · 2026-09-21

In short: Most Mickleham homes are structurally sound. The standard is failed when movement opens cracks wide enough to matter or when water finds its way in around windows and roofs, so the inspection looks for both.

Sound and weatherproof

The standard asks that the home is structurally sound and weatherproof. That covers the frame, walls and roof holding together, and the outside of the building keeping rain out.

Basalt clay and movement

Residual clay over basalt in Mickleham swells after rain and shrinks in dry summers. Fine cracks at the corners of doors and windows are common; wider or growing cracks, doors falling out of square or floors out of level point to movement that needs an engineer to assess.

Water getting in

Weatherproofing usually fails at windows, at flashings and through the roof. We look for stains and bulging in ceilings and take moisture readings near windows, using the thermal camera where it shows where water is travelling.

What the report says, and what it does not

We record what we see and say whether it points to movement or water entry. We do not certify structure; where cracking needs it, the report recommends a structural engineer.

FAQ

Questions Mickleham owners ask about this

Are hairline cracks a fail?

Not usually. Hairline plaster cracks are common in young homes on reactive clay. We record them, and flag wider or recurring cracking that could mean the home is not structurally sound.

Does a past leak fail the standard?

Staining from a leak that has been fixed is cosmetic. Active moisture, or mould from a leak that keeps happening, is a fail until repaired.

Do you go into the roof space?

Where it is safely accessible. Water stains on the underside of the roof and around penetrations often explain a ceiling stain below.

Is this a full structural report?

No. It checks the structural soundness standard visually. A structural engineer or a defect investigation goes further where needed.
