Rising Damp Specialists · Bardon
Salt tide-marks, peeling paint and that musty smell along the skirting boards? We diagnose and permanently treat rising damp in Bardon's older Queenslanders and brick homes — with a proper diagnosis and a permanent fix, not a paint-over.
Tell us what you're seeing — or what your building report said — and we'll arrange a no-obligation on-site inspection and written quote.
We connect you with QBCC-licensed damp specialists servicing inner Brisbane. No obligation. The specialist's assessment fee is $450 plus GST. That includes up to two hours on site diagnosis, that may include camera inspection of the stormwater drains.
Why Bardon homes are prone to damp: Bardon sits in the Mt Coot-tha foothills — ridges split by steep gullies, with some of Brisbane's steepest streets and Ithaca Creek running through. In February 2022, up to 1000mm of rain filled the Enoggera catchment and Ithaca, Fish and Enoggera Creeks flooded streets including Lorward Avenue and Carwoola Street. Steep cut-in blocks and creek flats give Bardon a real subfloor-moisture and rising-damp catchment.
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.
Local knowledge
Bardon (4065) is almost all stand-alone houses — a large share of them pre-1946 Queenslanders and interwar homes, protected by character controls. It sits in the foothills on the eastern side of Mt Coot-tha: ridges separated by steep gullies, with the main streets on the ridgelines and some of Brisbane's steepest side streets dropping into the gullies. Ithaca Creek runs through the suburb.
That shape funnels water. In the February 2022 deluge, up to 1000mm of rain fell across the Enoggera catchment over six days, Enoggera Reservoir peaked at 244% of capacity, and Ithaca, Fish and Enoggera Creeks flooded — with Bardon streets including Lorward Avenue, Simpson Road and Carwoola Street affected. Homes on the gully sides and creek flats take overland flow and flash creek rises, and a flooded subfloor stays wet for a long time. Check your address on Brisbane City Council's Flood Awareness Map.
On the steep blocks, homes are cut into the slope, so soil moisture presses against the lower walls and the subfloor drains poorly — on top of any creek exposure. We check rising, lateral and subfloor damp at the assessment and treat the source: usually subfloor drainage and ventilation with a chemical DPC.

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. It’s the same rising damp treatment in Brisbane we bring to every inner-suburb Queenslander.
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 2-year warranty. If it's needed, we'll advise on subfloor ventilation too.

Rising damp treatment is usually priced by the linear metre of affected wall, so the size of the problem drives the cost. As a 2026 guide across Australia: a specialist damp assessment typically runs $500–$1,500 (ours is free), a chemical damp-proof course from a few thousand dollars up to around $15,000 on larger double-brick homes, subfloor ventilation about $1,500–$5,000, and re-rendering salt-damaged plaster roughly $3,000–$10,000 per wall.
Most single-room Bardon jobs land in the low-to-mid thousands
Your home may need only one of these or a combination — the only way to know for your home is a free call.
Indicative figures only — 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 on site, because the three need completely different fixes.
That's one of the most common reasons Bardon 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 2-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 Bardon. 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.
Related. In February 2022 the Enoggera catchment took up to 1000mm of rain and Ithaca, Fish and Enoggera Creeks flooded Bardon streets like Lorward Avenue and Carwoola Street. Floodwater keeps a subfloor damp for years afterwards, feeding rising and subfloor damp. We check for residual flood moisture, true rising damp, or both.
Bardon's ridge-and-gully blocks are cut into the slope, so the uphill subfloor is dug into the hill and overland flow runs down onto the house. Soil moisture presses on the lower walls and the subfloor can't dry. The fix is usually subfloor drainage/ventilation plus a chemical DPC.
Yes — the work is carried out by QBCC-licensed damp and waterproofing specialists, fully insured, to Australian standards.
