The short answer
Somerset is the most house-dominated council in South East Queensland — 96.8% of occupied homes were separate houses at the 2021 Census — and much of it is acreage along the Brisbane Valley. Older country homes in Esk, Toogoolawah and Kilcoy, and river-flat properties around Fernvale and Lowood, are where most mould questions start.

Older country homes
Many of the towns’ houses are timber, high-set or on stumps, with long ownership histories and additions from different decades. Typical findings are a back verandah enclosed as a bathroom or laundry without waterproofing, a roof that has been patched rather than replaced, and gutters that overflow onto the walls. Mould shows on the enclosed verandah ceiling, on the inside of external walls and in wardrobes.
Moisture readings around each addition separate an old, dry stain from a current leak, which matters for what a buyer or owner needs to fix first.
River flats and valley fog
Around Fernvale, Lowood and Wivenhoe Pocket, cold air and fog settle along the river on winter mornings. Homes on low ground stay damp longer, and enclosed subfloors and lower-level rooms are slow to dry. Some river-flat properties have also been through floods. An inspection looks at the subfloor, the lower walls and the drainage around the house.
Acreage: name every building
On a rural block, the granny flat, the converted shed and the caravan someone lives in are as important as the main house. Each needs to be listed when booking. Rooms used for sleeping get the same moisture and surface checks as the house; storage sheds can be checked at representative points where belongings are kept.

Local questions
Is a stain on an old ceiling still a problem?
Not always. Moisture readings show whether the area is still wet. A dry, old stain may only need repainting; a damp one means a current leak to find.
Can a caravan or granny flat be included in the inspection?
Yes. Any structure used for living or storage on the property can be added to the scope.
