Mould Eradication & ULV Treatment (Fumigation)

We wash and sterilise the whole of the areas that have mould, any wallpaper that is contaminated will be removed and disposed of correctly. Once we have sterilised the areas we treat the mould roots that are in the fabric of the building.

All of our work is strictly priced by the Square metre relating to distance travelled to carry out the work from our office in the midlands. The ULV Treatment (fumigation) for airborne mould and pathogen spores is priced at a fixed price by the cubic metre.

Remember that if you own or rent a property Black Mould is a hazard to yours and your tenants health, and is classed as a statutory nuisance. We can eradicate it for you at reasonable cost. DO NOT WAIT TO BE SUED contact us.

Every property has within its structure mould spores which are dormant. However given the right conditions these spores germinate resulting in extensive growths of black disfiguring mould.

Mould is now classed as a statutory nuisance, and so to rent a property with a mould contamination could cause a few problems for you as the landlord, equally if you try to sell the property it may stop the sell due to the the unsightly looking walls etc and the fact that most people with think that there is a problem with the property due to the contamination.

We can eradicate the problem which will make the selling or the renting easier, we have found from our experience that it is better to have this work carried out before the estate agents are involved in the first instance, as they tend to remember the problem when they are called back into the property to give a valuation.

Mould in all of its guises requires very little nutrient to grow on walls and ceilings, irrespective of the decorative finishes. Mould spores will also create a further risk to health when they become airborne, (we can treat these as well).

When you have a mould problem just washing alone even with bleach WILL NOT solve the problem, only remove the unsightly blackness. However you can rest assured that it WILL return. Therefore the correct treatment is vital if eradication of the problem is to take place.

The life-cycle of a mould starts from the spore. Spores are loosely comparable to seeds in the vegetable kingdom. They are minute and are ubiquitous in the air.

The more humid the air, the greater the concentration of spores. Because of their small size, spores are carried long distances by air currents and only settle on surfaces in very still air. The spores can stay dormant for long periods of time, but when the conditions are right they will germinate. The necessary conditions for germination are generally: Temperatures of 10-35ºC with optima of 20ºC and above.

Relative humidities greater than 70% to give a high enough moisture content in the material for fungal growth. Wood becomes vulnerable to fungal attack when it has a moisture content above 20%, which equates to a relative humidity of above 80%. Suitable organic foodstuffs include paper, leather, wood, organic dirt, soiling and treatments such as leather dressings.

In general, mould growth is encouraged by dark conditions and a lack of air movement, but other factors can influence development. If conditions are suitable, the spores will ‘germinate’ and produce hair-like hyphae which both penetrate into the material and grow on the surface of the object.

Hyphae are filaments that are the growing stage of the mould. They secrete enzymes at their tips which dissolve organic material. The resulting solution is absorbed back by the hyphae and used as food for growth. When a mass of hyphae are present, the fungal colony is known as a mycelium.

Mycelia exist in two basic types: vegetative mycelia which penetrate deep into the material to grow, and reproductive mycelia which grow on the surface as visible mould. When the colony is mature, the reproductive mycelium can change to produce sporophores which are specialised hyphae, containing spores which are dispersed into the air to create new colonies.

Monitoring for fungi is normally carried out by monitoring the ambient relative humidity of the environment and measuring the moisture contents of objects. In general, organic materials in an environment with relative humidities over 70% are vulnerable to mould growth. This is because organic materials absorb moisture at high humidities, to a point when they can support fungal growth. Where mould is already present, lower humidities and moisture content may still continue to support mould growth for some time.

Control measures Long-term prevention of mould and control of outbreaks is only possible by effective environmental control to ensure that conditions are unsuitable for growth. The use of chemical fungicides and fumigants, while often successful, is not normally wholly acceptable as they have limited efficiency. The use of chemical fungicides and fumigants also does not address the underlying problem of poor environmental control or building defects.

Good preventative measures include:

Low temperatures Below 10ºC inhibits spore germination and slows growth. Very low temperatures (-40ºC) will eventually kill fungi.

Low relative humidity Below 70% to reduce the equilibrium moisture content of materials to a level where fungi cannot grow.

Anoxic environment Oxygen-free environments will slowly kill most moulds.

N.B. high temperatures above 50ºC will dehydrate and kill most fungi within a few hours. This can, where appropriate, be used as a control measure.

Treatment of mould outbreaks Active mould attack should be addressed with caution, as the mycelium and spores are respiratory sensitisers and can cause allergic reactions in some people.

This is an article sent to me, which explains what i have been telling people for years

Why you should not use bleach to try and kill black mould

Bleach-water solution vaporizes quickly but leaves the water behind. This, in effect, doesn't dry as fast as necessary to get rid of spores. Moreover, ordinary bleaches in our households contain 5.25% sodium hypochlorite or NaOCl. This sodium hypochlorite forms hypochlorous acid or HOCl when mixed with water. Hypochlorous acid is effective against bacteria and viruses thus bleaches are used as disinfectants. Studies revealed nonetheless that the use of bleaches is not suitable for home use due to some health risks. Aside from its health hazards, its effects against moulds are not much successful due to the water, which feeds the spores, left when bleach vaporizes. If you might notice when you use bleach-water mixture to remove visible moulds on your basement or bathroom walls, the moulds usually grow back after just a few days after you clean them.
