Black Mould

Black mould has gotten a lot of attention in the media in recent years, so it’s something of a celebrity villain these days. This property intruder is a dangerous presence, affecting the health and wellbeing of your property and anybody who inhabits it in a serious way. At Damp Surveyors & Damp Proofing UK, we understand the mechanisms behind the spread of black mould, and we can advise on ways to prevent it from happening in your property – as well as identify why it might be occurring at your site. If you have a black mould problem, or you’re worried about it emerging in the future, do yourself a favour and read on below.

How Does Black Mould Form?

Black mould is a common sight in properties across the United Kingdom, but you can resist the formation of black mould if you have a better understanding of how it forms in the first place. The main conditions that lead to the spread of black mould are poor ventilation, moisture, and humidity. When excess water vapour isn’t expelled from your property due to inadequate ventilation, it makes contact with surfaces that allow the water to permeate. The surface of this material will become damp, and black mould spores in the air will germinate within this moisture at the right temperature conditions.

Active or Inactive?

Before taking action against your black mould, it’s worth taking note of whether it’s active or inactive. If the black mould is slimy and wet, it’s black or dark green, and the patch appears to be growing in size – then it’s likely the mould is still active. Even if you clear away the mould, until the moisture source disappears, it’s likely to return. Inactive patches will be dry and powdery, and have a more grey colour palette. This indicates the water source has been removed, and while this is an improvement, it doesn’t mean there aren’t black mould spores in the vicinity – it’s still possible it can come back if moisture conditions are favourable.

Health Implications

Health concerns are the main factor in black mould getting so much more media attention in recent years – and it’s understandable why. If you have pre-existing health conditions, black mould is likely to make matters worse. Respiratory issues, breathing difficulties, asthma – these are the kinds of conditions that are massively exacerbated by the presence of black mould in your property. If you have nausea, a sore throat, you sneeze often, you have irritated eyes, or a number of other chronic symptoms, it could be that you have a black mould presence in your property.

Property Concerns

There are really no areas in your home that aren’t somewhat vulnerable to the growth of black mould, and it can be a real nuisance to deal with if it takes hold in your property. Black mould can grow on the walls, on your ceilings, behind furniture, in your showers, and in so many other places across your property.

Very often when black mould shows itself on an internal wall, we track the cause back to blocked guttering and/or downpipes which has then pushed the rainwater back into the roof space and then run down the internal walls of the property.

Roof & Driveway Cleaning London have eradicated this not uncommon problem for our clients on many occasions.

 

This can give an unpleasant distinct smell to the property, and it can also cause decay and deterioration on whatever surface it takes hold of too.
