Rising Damp Repairs in Perth
Federation Tuckpointing® provides rising damp inspections and repairs across Perth. We identify whether moisture is caused by a failed damp course, blocked wall cavity or external ground levels before recommending the right repair.
Rising damp is common in older double-brick Perth homes. Left untreated, it often leads to fretting mortar, damaged plaster, bubbling paint and deteriorating brickwork.
Signs Your Brick Wall May Have Rising Damp
Common signs of rising damp include:
- Bubbling or flaking paint,
- Bubbling render or plaster,
- Mould or moss growth,
- A damp odor or musty smell,
- Rotting skirting or flooring,
- Crumbling or fretting bricks
- Deteriorating mortar
- Tuckpointing coming away from the wall
These signs do not always confirm rising damp. Plumbing leaks, poor drainage and water entry from outside often create similar damage, which is why the source needs to be assessed before repairs begin.
What Causes Rising Damp in Brick Walls?
Rising damp occurs when moisture moves upward through porous brickwork and mortar from ground level. This often happens when the original damp course has failed, wall cavities are blocked with building rubble or external paving and garden beds sit above the damp barrier.
Older Perth homes are more vulnerable because many were built with ageing damp-course materials, double-brick cavities and lime-based mortar that absorbs moisture easily.

Our Rising Damp Repair Process
We begin by inspecting the affected wall and testing moisture levels. We also assess the condition of the mortar, bricks, damp course, cavity and surrounding ground levels to identify the likely source of the moisture.
From there, we recommend the right repair method for your home. In most Perth homes, we use a mechanical damp-course system. This involves removing the lowest course of bricks, clearing the cavity of rubble, installing a new damp-proof barrier, and re-laying the bricks. This solution is long-lasting and guaranteed.
Is It Rising Damp or Another Moisture Problem?
Not every damp wall has rising damp. Similar damage often comes from leaking pipes, blocked gutters, poor drainage, cracked render, garden beds against the wall or paving above the damp course.
Rising damp normally starts close to ground level and affects the lower section of the wall. A proper inspection helps identify the likely cause before repair work begins.
Rising Damp Repair Methods Used in Perth Homes
There are different damp proofing treatments available depending on what is required to solve the rising damp issue. Perth buildings have different types of brick walls that require different repair approaches. We assess the condition of the damp course and cavity before recommending the most appropriate solution.
- Silicone injection method
Small holes are drilled along the mortar joint or brickwork before a water-repellent chemical is injected into the wall. This creates a new barrier intended to reduce moisture movement.
Injection treatments often cost less than mechanical replacement. Their effectiveness depends on the wall type, condition of the masonry and whether debris remains inside the cavity. The drilled holes also remain visible unless repaired carefully.
- Mechanical damp-course replacement
The lowest course of bricks is removed in manageable sections. The wall cavity is cleared of rubble, a new physical damp-proof membrane is installed and the bricks are relaid.
For internal walls, damaged plaster is removed and replaced where included in the scope of work. This method restores a physical damp barrier and allows the cavity to be cleaned at the same time.
Federation Tuckpointing® generally recommends mechanical damp-course replacement for suitable double-brick homes because it addresses both the failed barrier and cavity debris.
