Damp that comes in sideways behaves differently, appears at a different height, and is not fixed by a damp course.
Talk it throughRising Damp Perth assesses and treats damp across the Perth metropolitan area.
Where ground is retained against a wall — a sloping block, a split level, a garage cut into a rise — water in that soil pushes through the wall horizontally. It shows as a patch or a band at the height of the retained soil, not as a tide-mark near the floor.
Lateral damp needs soil held against a wall: a split-level block, a garage cut into a rise, or ground built up behind the house during a renovation. Where any of those exists on a Perth block, rule it out before anyone quotes an injected course.
The work is drainage and tanking rather than injection: relieving the water behind the wall, then applying a barrier on the wet face. A chemical damp course does nothing here, and being quoted one is a sign the diagnosis was rushed.
| Work | Indicative range | What it covers |
|---|---|---|
| Drainage and ground-level correction | $900 - $6,000 | Lowering paving, cutting back garden beds, adding a drain. Where the cause is bridging rather than a failed damp course, this is the fix. |
Every range, and how the figures were set, is on the cost page. A fixed price follows the assessment.
