Mould & Damp Surveying

When you notice the first signs of damp in your home or workplace, it’s time to seek the expert advice of a damp surveyor. Ignoring these signs can lead to mould growth and damage to the building’s structure. At Hydro-X we offer professional mould and damp surveying to help identify issues and provide recommendations.

Dangers of Mould & Damp

Mould and damp pose a significant risk to people’s health, whether encountered in the workplace or at home. When left unchecked, mould can release harmful spores into the air, causing reactions such as coughing, sneezing, and irritation to the eyes, nose, and throat. For individuals with respiratory conditions like asthma, mould spores could make their conditions much worse.

Apart from health concerns, mould and dampness can weaken the structure of a building. Mould growth on walls, ceilings, and floors can gradually degrade the materials, leading to structural damage and deterioration. Dampness can also cause wooden structures to rot, compromising their strength and stability. Moreover, mould and mildew can infiltrate insulation and ductwork, reducing their effectiveness and potentially causing costly damage.

Addressing mould and damp issues promptly through remedial works, proper ventilation, moisture control, and regular maintenance is crucial to safeguarding both the health of occupants and the integrity of the building.

What is Penetrating Damp?

Penetrating damp is a type of moisture issue that occurs when water infiltrates a building through external walls or roofs, subsequently seeping into the internal spaces. It often occurs due to defects in the building’s structure, such as cracks in walls, gaps around windows, or damaged roof coverings. Factors like heavy rain or faulty guttering worsen the issue. Once inside, the water can cause visible damp patches on walls or ceilings, as well as potential damage to plaster, paint, or other finishes. If left untreated, penetrating damp can lead to more severe issues like mould growth, decay of timber structures, and degradation of building materials.

What is Rising Damp?

Rising damp is the upward movement of moisture from the ground through porous building materials, causing dampness in lower sections of buildings. It’s identified by tide marks or damp patches on interior walls, often accompanied by peeling paint or crumbling plaster. Factors like inadequate damp-proof courses or high ground levels worsen the issue. Left untreated, rising damp can lead to structural damage and mould growth.

Why Should You Get a Damp and Mould Survey?

Getting a damp and mould survey is essential to identify and address potential issues early on. It helps prevent further damage to your property, protects your health by addressing mould growth, and ensures a safe and comfortable environment for occupants. Early detection through a professional survey can save you time, money, and hassle in the long run, as it allows for targeted remediation measures tailored to your specific needs.

The Homes (Fitness for Human Habitation) Act 2018 has also now been in force for over 5 years, meaning landlords must ensure their properties provide “freedom from damp” to tenants.
