Rising Damp Subiaco WA | Treatment & Advice

Rising Damp Perth assesses damp in Subiaco, WA 6008, and we meter the wall before we quote.

What Subiaco's building stock does to a damp wall

Paint and render failing on the rendered base of an older outside wall, with white salt on it and stone footings below.

Subiaco is Federation brick and tuckpointed limestone, and two different damp problems can sit on the same street. Where soil has been built up against a back wall over the years, water can come through the wall sideways: lateral damp. Where a raised garden bed was added above the original damp course, it is true rising damp over a bridged course. Where renovation put non-breathable render over old limestone, that render traps the moisture in the wall.

Where soil is built up, the damp can come sideways

Where soil sits higher against one side of a house, water can enter through the wall itself rather than up from the footing. That is lateral damp, and it is a different problem with a different fix — drainage and tanking rather than an injected course. The two look similar on a stripped wall and are easy to confuse. Two houses on the same street can have different diagnoses, which is why a diagnosis from the street is worth nothing.

Also relevant to Subiaco, and written once for every suburb it affects: cement render over old masonry.

What the Subiaco numbers mean for a damp wall

Subiaco is 6.6 km from the coast, far enough that salt off the wind is unlikely to be the main source of salt in a wall. So the first things to check are what has been built against the walls: raised beds, paving and back-garden fill. The Swan River is 2.8 km from the centre, so a high winter water table is a question for a specific address, not a given for the suburb.

What to check first in Subiaco

The outside ground level against the floor inside, wall by wall. Where soil in a Subiaco garden sits higher than the floor, the damp on that wall may be lateral.

Prices and next steps for Subiaco

The six signs are on the inspection page, the order of the work on how it works, prices on the cost page and the measuring method on the about page.

If the water comes through the wall sideways, the drainage and ground-level row applies, not the injection row.
