What are the main differences between mould and damp?

Anyone who becomes a homeowner will be aware of the many responsibilities that they face to ensure that their investment is worthwhile and continues to rise in value. Those located in London have a good chance of achieving this with careful care and attention, as properties continue to be in high demand. While some might put décor and the purchase of things to improve the comfort in their home at the top of the list, it is unwise to neglect regular inspections.

They might reveal that there are issues that need dealing with of far more importance, and they might be eating away, sometimes out of sight, that damage the structural integrity of a building and will require a lot of money to put right. Damp and mould are enemies of homeowners, who, if any doubt, should arrange an independent damp survey as quickly as possible to nip any issues in the bud. But what are the main differences between mould and damp?

Let’s first consider their definition. Damp refers to unwanted moisture or water ingress in a property, and can be penetrative, which gets its opportunity to flourish through gaps in a structure, or rising, which, as the name suggests, comes from the base and foundations of a building. Mould, on the other hand, is a type of fungus that grows when damp conditions persist. One thing they have in common is that they can both cause big issues. Independent damp surveyor London is the phrase to look for online to get confirmation, so that any issues can be dealt with. They will be able to explain that damp is caused by leaks, condensation, poor ventilation, or rising moisture from the ground, whereas mould develops because of dampness, thriving on the wet surfaces it creates.

A PCA independent damp surveyor will be able to quickly identify any possible problems which have giveaway signs in their appearance. Damp usually shows as discoloured patches, staining, peeling paint, or salt deposits on walls, while mould appears as slimy patches in shades of black, green, or white. The smell created by the two often alerts homeowners that something is wrong, with the musty or earthy odour of damp and the stronger, more pungent smell due to the fungal spores in mould being unmissable.

A big reason to take both mould and damp seriously is their health impacts. Mould can trigger allergies, respiratory problems, asthma, and skin irritation. Damp can make an indoor environment feel uncomfortable and encourage pests. Damp and timber independent surveys are an excellent way to quell any concerns, as damp can quickly spread without corrective action, and mould spreads quickly via airborne spores and finds new damp areas to grow in. Mould can remain hidden, which is why expertise is required, while damp is often noticeable as a stain or wet area.
