Rising Damp Perth assesses damp in Leederville, WA 6007, and we meter the wall before we quote.
Leederville's older cottages are surrounded by hard surfaces built up over the decades, and those surfaces can shed water toward the older walls. A wet wall here can be surface water rather than rising damp, and the two need different work.
Where hard surfaces surround an older house, stormwater that once soaked away now runs off them and ponds against the walls in its path. The wall gets wet from the outside, repeatedly, and the tide-mark looks like rising damp. Establishing which it is comes before anyone injects anything, because an injected course does nothing about water arriving at the surface.
On the sand ridges water normally moves down and away, so damp here is more likely to be about something interrupting that rather than about the water table. A slab, a paved area, a compacted layer of fill or a buried footing can all hold water against a wall that would otherwise have drained. That makes the diagnosis a question of what has been built, and when — which is answerable, and worth answering before any treatment is quoted.
| Ground level within 250 m | 17 to 27 m above sea level (approx.) |
|---|---|
| Ground level at the centre | about 19 m |
| Indian Ocean coast (salt air) | about 8.2 km from the centre, straight line |
| Nearest river | Swan River, about 3.4 km from the centre, straight line |
| Perth CBD | about 2.8 km, straight line |
| Streets inside the suburb | Oxford Street, Vincent Street, Newcastle Street and Loftus Street |
| Parks and reserves | Keith Frame Reserve, Brittania Reserve and William Traylen Gardens |
The detail above points to surface water: run-off from paving and roofs that collects against a wall. Check whether the mark gets worse after heavy rain, not only through the winter months. At 8.2 km from the coast and 3.4 km from the Swan River, neither sea salt nor the river is the first suspect.
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.
