What we look for in Fremantle, and why it differs from the suburb next door. 14.8 km from the CBD, on the coast, postcode 6160.
Fremantle has the best preserved nineteenth century port streetscape anywhere in the world, and the whole West End is heritage listed. More than 250 buildings. That is the backdrop, but the thing that actually governs an inspection here is what the buildings are made of. Early regulations pushed builders toward limestone to stop the sand drifting, and the stone was quarried locally, so the typical old Fremantle house is solid limestone laid in lime mortar.
Solid limestone walls have no cavity and no damp proof course. Damp at the base of a wall is therefore normal. It is not automatically a defect, and a buyer who panics at the first sign of it will walk away from perfectly good buildings. What we look for is whether the damp is being managed or made worse.
Cement is what makes it worse. Someone renders a limestone wall in cement, or repoints it in cement, and the moisture that used to breathe out through the mortar now has nowhere to go except through the face of the stone. The stone frets. It crumbles back in layers. We flag cement render on limestone as a finding in its own right, because well meant repairs here cost more than neglect ever did.
Suspended timber floors and limestone cellars come with the territory, so subfloor access matters. Add airborne salt from the port working on metalwork and fixings, and heritage listing that limits what you are allowed to change, and the picture is complete. Check the listing before you plan anything.
Old Fremantle houses give termites two things they want. Timber, and damp. The floors sit on stumps over ground that holds moisture against unventilated walls, and the subfloor is where colonies establish long before anything shows upstairs. Blocked or built-over vents are the single most common contributor we see.
Much of the original structural timber is jarrah, which resists termites well. It does not stop them. After a hundred and forty years the softer replacement timbers, the pine used in later additions and the framing inside converted commercial spaces are all fair game. Cellars complicate access. So do rear laneways and buildings that sit hard against their boundaries, because a perimeter you cannot walk is a perimeter you cannot properly assess, and the report has to say so.
In Fremantle the two inspections answer the same underlying question, which is how water is moving through an old building. Damp feeding a termite colony under the floor is usually the same damp fretting the stone above it. Running the building and timber pest inspections as one job means one attendance, one set of access arrangements for a tenanted or awkward property, and one coherent story about the place. The building side is reported to AS 4349.1 and the pest side to AS 4349.3.
Fremantle is not only old houses. The West End and the harbour edge hold apartments and converted warehouses, and strata inspections there are a different job again. Concrete, membranes, facades and the question of what the scheme has spent versus what it has deferred. A special levy for facade repairs on a salt exposed building is a real number and it belongs in your calculations before you buy.
We also do pre-settlement inspections, which matter more here than in a new suburb because vendors of old buildings sometimes do quick cosmetic work between offer and settlement. Where a neighbouring site is being redeveloped, and in the West End that happens often, a dilapidation report records the state of your walls before the excavator starts. On heritage buildings that record is worth having.
Fremantle sits on the Quindalup dune system — young calcareous sand, still mobile in places, and thin over the water table near the front. Sand this young has low bearing capacity but very little reactivity, so footing movement is uncommon and drainage problems are not. What the ground gives you here it takes back in the air.
What that means in practice, on a house in Fremantle:
Landform is assigned from the suburb's position on the Swan Coastal Plain rather than from a site soil test. It tells you what to expect, not what you have. A site classification to AS 2870 is a different exercise and a different report.
Fremantle Arts Centre is the fixed point most people in Fremantle navigate by. Buildings like it are useful to an inspector for a duller reason: they date the area. Whatever era put that up is usually the era that put up the houses around it, and the construction methods of that decade are what we expect to find in the roof.
White Gum Valley, South Fremantle, Beaconsfield, East Fremantle and North Fremantle sit on the same ground as Fremantle, so the footing behaviour and the drainage problems tend to repeat across all of them. If you are comparing houses across those suburbs, you are largely comparing the same site conditions.
Palmyra is 2.5 km away but sits on the Spearwood dune system. That is the useful thing about this part of Perth: the ground can change inside a few kilometres, and with it what an inspection is looking for.
On site classification: any soil zone quoted for a suburb is indicative, inferred from geography rather than surveyed. A real AS 2870 classification comes from geotechnical work on your actual block and can differ from the one next door. We report what we observe; we do not read your soil class off a map.
The inspection is visual and non-invasive, over the readily accessible areas, reported to AS 4349.1. Our inspectors physically enter the roof space, as long as there is sufficient access. Report within 24 hours of the inspection.

Right on the coast in Fremantle — the band where coastal salt drives the defects. The fee concentrates on delignified battens, corroded ties and fixings, and the salt staining that starts inside the masonry, with the roof space taking the longest on a tiled roof past its first decade.

Yes. Our inspectors physically enter and inspect the roof space, as long as there is sufficient access to do so safely. Where access is restricted, the report says so plainly rather than implying we saw more than we did.
Fremantle is on the coast, inside the band where delignification should be expected in tile battens. On a tiled roof more than about ten years old it is one of the first things we look at.
Within 24 hours of the inspection itself, not 24 hours from booking. On a pre-purchase or pre-settlement job that timing is the whole point, because your leverage disappears once you are committed.
