7 essential tips to help you successfully deal with mould in your home
If you've been unlucky enough as a homeowner to have experienced mould, you know how
unpleasant it can be. Black mould and spores, occur in areas of high condensation and
should be of concern to any homeowner. Mould occurs when the warm air is ridden with
moisture, which rises until it reaches a cold surface, the cold surface cools the air and
the resulting moisture condenses on the surfaces when it comes into contact with it.
With enough condensation and a slightly warm environment mould can thrive and survive. Some
examples of an ideal environment for mould to develop, will be your bathroom or shower room,
specifically starting as patches on the celling or wall, and expanding to tiling grout and adhesive.
Moisture rich areas are the perfect conditions for black mould spores specifically to grow, and
this should be of concern.
Black mould or (Stachybotrys chartarum) is a type of micro fungus, it has the capability to
produce conidia which as an asexual reproductive spore, can reproduce exponentially,
within a wide range of moisture based condition. This reproductive characteristics
greatly assists in the ability for spores to multiply and spread.
Mould exists in small quantities in grain and soil, and is mostly found in cellulose rich
building materials affected by damp or water ingress. This means that a moisture rish environemnt,
coupled with exposure to materials designed to absorb moisture, in the abscence of ventilation,
means mould can make it's way into your home, in expected areas, relatively easily.
By reducing the quality of mould resistnace materials, in certain project builds,
coupled with the design for ventilation of moisture, means a mositure rich environment
can be the noraml setup. This means homeowners, get frustrated with mould gorwth on ceilings, tiles, basins,
etc. The alternative is to have 'less baths/showers' and reduce the fungi collection on surface, or try to manage
ventilation or moisture withdraw (such as dehumidifiers) to manage the development of the issue.
As you know, most homes are designed with servicing the grid, this means, that attraction of heat to
resolve an issie with mositure, can make a difference.
Couple that with the ideal conditions in the UK, and an environment of about 70 degrees Fahrenheit (21
degrees Celsius) and a relative humidity (concentration of water in the air) of 70% and this
is the perfect storm for mould to quickly reproduce and spread, whistl supporting cost increase for
management of mould through the purchase of dehumidifier, heaters, ventialtion re-work euc..
When dealing with mould it is important to consider wearing the right apparatus and/or
protective clothing before attempting to remove any mould from surfaces; particularly if you
are a tradesperson who does this regularly. The reason being, the spores in the air form a
fine dust which when inhaled can cause health and safety issues, including severe
respiratory or breathing problems. Care should also be taken to leave the environment worked
in safe for the homeowner and their families, during each phase of the removal and
There are a number of ways to reduce the risk of mould presenting, (this assumes no mould is
present) the top three being:
1. Reducing the moisture created from circulating in the air by using a good dehumidifier
(dehumidifiers remove moisture from the air).
2. Heating and insulation, this will reduce the area of cold surfaces, cause the air to
retain the moisture, whilst prevent condensation.
3. Having a ventilation unit or an extractor fan, to remove moisture-laden air before it can
settle on a surface. Doing this in conjunction with insulation is recommended to maximise
the effect. These approaches reduce the risk of mould forming, but there will still be some
moist air in places, especially the bathroom or shower room and this means that there is
still the likelihood of mould recurring.
Other methods can be adopted but should be weighed by the benefits and risks associated, for
4. Opening windows can make the room cold, whilst this is not so welcome in winter, it can
remove moisture ridden air, and change the environmental temperature, making it difficult
for spores to settle and reproduce.
5. Installing heating and insulation may prove expensive depending on your circumstances,
but again can prevent mould settling due to the temperature of the surface area, where the
insulation is placed, it may be that killing mould rather than preventing it may also be a
more affordable option.
6. If you have a pre-existing outbreak, cover the surface area with a steriliser or mould
killer based product, follow the instructions to remove the mould, clean and prepare the
area, as recommended by the product. You can then use a barrier solution undercoat product
and once the barrier solution has dried, apply the top coat ensuring it is mixed with a
fungicide additive, this product formulation should have instructions on how to prevent the
mould returning. Mould eradication kits are also available and a good product can clean a
huge surface area, whilst the fungicidal properties they have should eradicate the mould
7. Other simpler methods include bleach, mould and mildew products or antifungal sprays.
My friend Claire, had a recurring mould problem in her shower, as she has asthma, she was

She found Peter on Billntrade.com's marketplace, Peter is a tradesman
skilled in painting and decorating, as well as mould removal and restoration. Peter uses
Billntrade.com to find local jobs and manage his business. Over a couple of sessions he was
able to remove the mould, treat the areas and restore it using the right paint, emulsion,
protective and preventative products. Claire said, 'Peter did a wonderful job, restoring my
shower room and prevented my asthma from getting worse. I would recommend Peter to anyone
who has a similar problem'.
