Black Mould Can Devalue Your Home By £50,000

As a homeowner, one of the most concerning issues you can face is black mould. It’s not just an unsightly problem; it can also pose serious health risks if left unchecked. Identifying the signs of black mould early and knowing when to seek professional help can protect your health and your home. Here’s what to look for and when to take action, according to expert Alison Graves from Hyperion Tiles.

Visible Mould Growth

The most obvious sign of black mould is visible growth. Black mould often appears as dark, slimy spots on walls, ceilings, or other surfaces. It can be black, dark green, or even dark brown. If you see mould growing in your home, it’s a clear indication that there’s a moisture problem that needs addressing.

Musty Odours

Black mould emits a distinctive musty smell. If you notice a persistent musty odour in certain areas of your home, especially in bathrooms, basements, or areas prone to moisture, it could indicate hidden mould growth.

Water Damage

Signs of water damage, such as discoloured walls, peeling paint, or water stains, can indicate the presence of mould. Mould thrives in damp environments, so any area that has experienced water damage is at risk.

Health Symptoms

Exposure to black mould can cause various health issues. If you or your family members experience unexplained allergic reactions, respiratory problems, headaches, or skin irritation, mould could be the culprit. Pay attention to symptoms that worsen when you’re at home and improve when you’re away.

Condensation and Humidity

Condensation on windows, pipes, or walls, as well as consistently high humidity levels, create ideal conditions for mould growth. Use a hygrometer to monitor indoor humidity and keep it below 50% to prevent mould from thriving.

Cracked or Peeling Paint

Cracked or peeling paint, especially in areas prone to moisture, can be a sign of hidden mould growth. As mould grows, it can cause paint to lift and bubble.

Warped Walls or Flooring

Warped or bulging walls and flooring can indicate a serious moisture problem, which can lead to mould growth. If you notice these signs, investigate the source of the moisture immediately.

The Financial Impact of Untreated Mould

Untreated mould can significantly devalue your home. On average, the presence of mould can reduce a property’s value by 20%, which translates to thousands of pounds. For instance, if your home is valued at £250,000, the presence of untreated mould could decrease its value by as much as £50,000. This devaluation is due to the perceived health risks and the costs associated with mould remediation that potential buyers factor in when considering a purchase.

When to Seek Professional Help

While some mould issues can be handled with DIY solutions, certain situations require professional intervention. Here are scenarios where you should call in the experts:

Large Affected Areas

If the mould covers an area larger than 10 square feet, it’s best to seek professional help. Large infestations often indicate a significant underlying problem that needs professional expertise to resolve.

Hidden Mould

If you suspect mould growth but can’t see it (due to musty odours or health symptoms), professionals can use specialised equipment to detect and remediate hidden mould.

Health Concerns

If anyone in your household has health issues related to mould exposure, such as severe allergies or asthma, it’s crucial to have professionals handle the mould removal to ensure thorough and safe remediation.

Recurrent Mould Problems

If mould keeps returning despite your efforts to clean and prevent it, this indicates a persistent moisture problem that needs professional assessment and correction.

Alison Graves of Hyperion Tiles says:

“Mould is not just a cosmetic issue but a potential health hazard. Early detection and proper remediation are key to protecting your home and health. If you notice any signs of black mould or experience unexplained health issues, don’t hesitate to seek professional help. Timely intervention can prevent costly damage and ensure a safe living environment.”
