Mould-in-Rushcutters Bay: Causes, Rectification & Health Risks
Mould is a serious issue that can plague many older homes in Rushcutters Bay, particularly those with brick or stone foundations. This insidious problem occurs when moisture from the ground travels upwards through the walls, causing significant damage and posing health risks to occupants.
Causes of Mould in Rushcutters Bay
Lack of Damp-Proof Course: Older homes may lack a proper damp-proof course, a barrier installed at ground level to prevent moisture penetration.
Breached Damp-Proof Course: Even if a damp-proof course exists, it can become breached due to:
Soil movement: Shifting soil can crack or dislodge the damp-proof course.
Poor construction: Incorrect installation or inadequate materials can weaken the barrier.
Physical damage: Roots, excavations, or even minor impacts can compromise the course.
Ground Water Levels: High groundwater levels can exert significant pressure on the base of the walls, forcing moisture upwards.
Poor Sub-floor Ventilation: Inadequate ventilation under the floor allows moisture to accumulate, creating a damp environment that encourages rising damp.
Blocked Drains: Blocked drains can cause groundwater to back up and increase the risk of rising damp.
The Impact of Mould
Mould can have a devastating impact on a property and its occupants:
Structural Damage:
Deterioration of plaster and paint: Moisture weakens plaster, causing it to crumble and peel. Paint can also blister and peel.
Rotting timber: Damp conditions encourage the growth of fungi and bacteria, leading to timber rot. This can affect floorboards, joists, and even structural beams.
Salt damage: Salts in the ground can be drawn up with moisture, causing efflorescence (white powdery deposits) on walls and damaging bricks.
Health Risks:
Respiratory problems: Damp conditions can trigger or exacerbate respiratory issues like asthma, allergies, and bronchitis.
Mold growth: Mold thrives in damp environments, releasing spores that can cause respiratory problems, skin irritations, and even more serious health issues.
Pests and insects: Damp conditions attract pests like silverfish, woodlice, and termites, which can further damage the property.
Reduced Property Value: Rising damp significantly diminishes the value of a property. Potential buyers will be wary of the associated costs and health risks.
Rectification of Mould in Rushcutters Bay
Professional Assessment: The first step is to engage a qualified Mould specialist to conduct a thorough assessment. They will identify the source of the damp and recommend the most appropriate course of action.
Installing a New Damp-Proof Course: This involves excavating around the base of the property and installing a new, robust damp-proof course. This may require underpinning the foundations in some cases.
Improving Sub-floor Ventilation: Enhancing sub-floor ventilation is crucial. This can be achieved by installing new vents, improving existing vents, and ensuring adequate airflow under the floor.
Treating and Replacing Affected Materials: Damaged plaster, timber, and other materials will need to be treated or replaced. This may involve removing and replacing sections of walls, flooring, and even joists.
Addressing Ground Water Issues: If high groundwater levels are a contributing factor, measures may be necessary to lower the water table or divert groundwater away from the property.
