Rising Damp Specialists · Auchenflower
Salt tide-marks, peeling paint and that musty smell along the skirting boards? We diagnose and permanently treat rising damp in Auchenflower's older Queenslanders and brick homes — with a proper chemical damp-proof course, not a paint-over.
Why Auchenflower homes are prone to rising damp: Auchenflower's river-facing slopes flooded in both 2011 and 2022, and its dense stock of Federation-era homes is among the oldest in Brisbane's inner west. Many were built with Federation-era Queenslanders and early masonry homes — often with no damp-proof course at all, or one that failed decades ago. Combined with the Brisbane River nearby, humid summers and clay soils, moisture wicks up through the brick piers and masonry and shows up as salt staining a metre up the wall.
Know the signs
Rising damp only affects ground-floor walls, because the moisture comes from the soil. If you're seeing these signs low on the wall, it's worth a proper look before it damages the timber and brickwork.
SIGN 01
A horizontal stain about a metre up the wall, where the rising moisture peaks and evaporates.
SIGN 02
Efflorescence — ground salts crystallising on the brick or plaster surface.
SIGN 03
Finishes lifting and crumbling near the base of the wall.
SIGN 04
Soft, damp or warped skirting boards, architraves and floor timbers.
SIGN 05
A persistent damp, earthy odour, often strongest in closed rooms and low cupboards.
SIGN 06
In bad cases, the face of the brick crumbles away as the salts destroy the mortar.
How we fix it
Rising damp is often misdiagnosed as condensation or a leak, which need completely different fixes. We diagnose the actual cause first, then treat the source — not just the stain.
We inspect with moisture meters, confirm it's genuinely rising damp, and rule out condensation or lateral damp.
We inject a new DPC into the mortar course — a water-repellent barrier that stops moisture rising, without removing bricks.
We strip salt-damaged plaster and apply a salt-retarding render so the damage doesn't return through the new surface.
We make good the wall and back the work with a 20-year warranty. If it's needed, we'll advise on subfloor ventilation too.

Most rising damp work is priced by the linear metre of affected wall.
Chemical DPC injection: roughly $200–$400 per linear metre
A typical single-room job runs into the low thousands; a whole-house Queenslander with salt-damaged plaster and re-rendering can be more. The only way to know for your home is a free on-site assessment.
Every home differs — wall length, damp height and salt damage all change the price. We quote fixed, in writing, after the assessment.Common questions
Rising damp only affects ground-floor walls and peaks at a fairly even height — about a metre up — often with a salt tide-mark. Condensation usually shows higher and in corners or on cold surfaces; a leak is more localised. We confirm which one it is with moisture meters during the free assessment, because the three need completely different fixes.
That's one of the most common reasons Auchenflower owners call us. A building inspector flags the problem but doesn't fix it. We come out, confirm the extent, and give you a written quote you can use to negotiate on the purchase or plan the repair. Send us a photo of the report finding and we'll talk you through it.
If it's treated properly — a correctly installed chemical DPC plus salt-retarding render — it shouldn't. The 20-year warranty covers the workmanship. Paint-overs and quick fixes are what come back, because they don't stop the moisture at the source.
Yes — that's the bulk of the work in Auchenflower. Older Queenslanders often have no damp-proof course and poor subfloor airflow, so we frequently pair the DPC treatment with subfloor ventilation to keep the underfloor space dry.
Most residential jobs take one to a few days depending on wall length and how much plaster needs replacing. In most cases you can stay in the home; if a room needs to be closed off during treatment we'll let you know in advance.
