How Damp Can Affect Your Health and What to Do About It

Quick Summary: Damp in homes can lead to serious health issues, especially for children, the elderly, and those with existing respiratory conditions. Mould spores, bacteria, and increased humidity can trigger asthma, allergies, and infections. Professional damp proofing in South London is essential to prevent these damp-related health risks and create a safe living environment.

Why Damp in Your Home Should Never Be Ignored

When left untreated, damp doesn’t just damage your property—it can severely impact your health. From mould growth to airborne allergens, the health effects of damp are far-reaching. If you live in South London, where older homes and high humidity levels are common, getting professional damp proofing in South London is not just a matter of property maintenance—it’s a health safeguard.

The Most Common Damp Problems in Homes

Rising Damp

This occurs when moisture from the ground travels up through the brickwork. It typically causes tide marks, peeling wallpaper, and musty smells.

Penetrating Damp

Caused by water seeping through walls due to defective brickwork, gutters, or roofs. It often results in damp patches, black mould, and crumbling plaster.

Condensation

The most common form of damp, especially in winter, condensation occurs when warm, moist air meets cold surfaces. It leads to surface mould and water droplets on windows and walls.

Damp problems in homes often start small but quickly escalate if not addressed early. Each type of damp carries unique risks that can affect your family’s well-being.

Health Effects of Damp You Should Know

Living in a damp environment can cause or aggravate a range of health problems. The NHS and WHO both recognise damp and mould as significant contributors to respiratory and skin conditions.

1. Respiratory Illnesses

Mould spores in the air can trigger asthma, bronchitis, and chronic coughing. Individuals with existing respiratory conditions are especially at risk.

2. Skin Conditions

Eczema and rashes are common health effects of damp, particularly in young children and those with sensitive skin.

3. Allergies

Dust mites thrive in humid, damp environments, making allergic reactions like sneezing, watery eyes, and sinus issues more likely.

4. Immune Suppression

Long-term exposure to damp and mould has been linked to reduced immune function, especially in the elderly and very young.

Real-Life Example:

A 2022 Public Health England report highlighted that children in homes with mould were 40% more likely to develop asthma-like symptoms compared to those in dry environments.
