Black damp mould

Do you have black damp mould?

Mould growth can often begin with a subtle appearance—just a small, dark black patch that, if left unattended, can expand rapidly into a much larger issue. Initially, this small spot may seem harmless, but it serves as a warning sign of underlying moisture problems that can deteriorate the integrity of your home. If the mold is allowed to proliferate, it can cover vast areas, leading to significant structural damage and potential health risks for occupants. Therefore, it’s crucial to address mold growth immediately upon detection and to investigate the cause of the moisture that is allowing it to thrive. Proper remediation and prevention measures will not only restore the aesthetic quality of your environment but also ensure a safe and healthy living space.

Rising damp

Condensation & Black Mould

Penetrating Damp

Rising damp occurs when moisture travels up through walls from the ground due to a damaged or missing damp-proof course. Common signs include tide marks, flaky paint, salt deposits, or peeling wallpaper near the skirting. If ignored, it can cause serious structural and cosmetic damage to your home. Our solution involves removing affected plaster, injecting a chemical damp-proof course, and re-plastering with specialised materials that resist further moisture. This service is ideal for older properties and guarantees a clean, dry finish. With proper treatment, rising damp can be permanently resolved, keeping your walls strong, breathable, and looking like new.

Condensation is a leading cause of black mould in UK homes, often found in bathrooms, kitchens, and bedrooms with poor ventilation. It forms when moist air hits cold surfaces, creating damp patches where mould can thrive. Black mould is not just unsightly—it can trigger respiratory issues and worsen asthma. We assess airflow, identify moisture sources, and provide ventilation improvements, anti-mould treatments, and breathable plastering. Our service ensures affected areas are cleaned, treated, and protected long-term. Stopping condensation at the source helps safeguard your health and property. We leave your home cleaner, fresher, and more resistant to mould re-growth.

Penetrating damp happens when rainwater enters your home through defects in external walls, such as cracked brickwork, failing render, or damaged pointing. It can cause visible damp patches, mould growth, and even damage internal finishes. This type of damp doesn’t rise from the ground—it enters horizontally, often during heavy rain. We identify and fix the root cause, whether it's faulty gutters or worn-out mortar, then dry the area and re-plaster where necessary. Our approach prevents further water ingress and restores your home to its original condition. Effective penetrating damp treatment also helps improve energy efficiency and indoor air quality.
