Frequent boiler pressure loss and regular refilling are strong indicators of mains-related leaks.

Professionals first identify all root causes. They then use biocides or fungicides and apply solutions with cloths rather than spraying, which prevents spore dispersal.

Bleach does not eliminate the root system. It leaves mould dormant, allowing it to regenerate quickly. For more advice, read our expert guide on cleaning mould with bleach.

Mould on walls can be caused by condensation, water leaks, penetrating damp or a combination of moisture-related problems.

Condensation commonly occurs on cold surfaces and in areas with restricted airflow, such as behind furniture, around windows and in external wall corners.

Water leaks may cause localised dampness, staining, peeling paint or damage to plaster, although these symptoms are not always present.

The location and appearance of mould can provide useful clues, but they cannot reliably confirm the cause on their own.

At Cornerstone, our independent damp and mould surveys use moisture assessment, atmospheric measurements and other investigative methods to determine the likely source of the problem. Book a survey today!

Living in a property affected by damp and mould can increase the risk of respiratory symptoms, allergic reactions and irritation of the eyes and skin.

People with asthma, allergies or existing respiratory conditions may be particularly vulnerable. Babies, children, older people and those with weakened immune systems can also be at greater risk. The health effects depend on individual circumstances, and visible mould colour alone does not establish the level of risk.

Identifying and addressing the source of moisture is essential to reducing further mould growth.

At Cornerstone, we provide damp and mould investigations to help homeowners and housing providers understand the causes of moisture problems and identify appropriate corrective action.

Most lack proper biocidal or fungicidal agents. They clean the surface but leave the root system intact, giving a false sense of resolution.

Black mould is not necessarily more dangerous than other types of mould simply because of its colour. Different mould species can affect people differently, and the risks depend on factors including the extent of contamination, exposure and individual health conditions.

Black-coloured mould cannot be reliably identified by appearance alone. Any persistent indoor mould should be investigated, particularly where occupants have respiratory conditions or other vulnerabilities.

The most effective approach is to identify the moisture source, address the underlying cause and remediate affected materials appropriately.

At Cornerstone, our damp and mould reporting services help establish the building-related conditions contributing to mould growth.

The appearance of damp or mould does not always reveal whether the problem is superficial or caused by an underlying building defect.

Surface condensation can encourage mould growth on cold walls and in poorly ventilated areas. However, leaking pipes, damaged roofing, defective external walls or other sources of water ingress can cause moisture to accumulate within the building fabric.

Signs such as repeated staining, deteriorating plaster, persistent wet patches or mould returning after treatment may justify further investigation.

At Cornerstone, we provide root cause analysis to investigate recurring property defects and identify the factors responsible before remedial works are recommended. Get in touch with us today!

Mould often returns after cleaning because the moisture conditions responsible for its growth have not been resolved.

Common causes include condensation, inadequate ventilation, cold surfaces, water ingress and hidden plumbing leaks. Cleaning visible mould without dealing with the underlying moisture problem may only provide a temporary improvement.

If mould repeatedly appears in the same area, a professional mould investigation can help determine whether the cause is environmental, structural or related to a leak.

At Cornerstone, we offer a comprehensive damp and mould investigation service that focuses on identifying the underlying cause and recommending suitable corrective action. Discuss your concerns with our mould experts today!

Many people assume evacuation is the only response. In commercial settings, proper extinguisher placement and staff training can sometimes prevent major damage.

Smoke penetrates deep into building structures. Even after visible restoration, lingering odours may remain if the fabric of the building has not been properly treated.

This is common in homes, where people instinctively use water without identifying the fire source. Using the wrong method can spread damage and increase risk.
