What is Mould?

Mould is a type of fungus that can thrive in any building, new or old, particularly where the atmosphere is damp and poorly ventilated or warm, moist and stagnant. Not only is mould unsightly, it can have a damaging effect on furniture and fabrics. Moreover, mould can affect one’s lungs and cause breathing difficulties. It is classified as a category one health risk to health under the Housing Health and Safety Rating System 2000, which places it in the same class as asbestos.

Prevention is Better Than Cure

Once your immediate black mould problem has been addressed, we may install dehumidifiers and air movers to start the drying process to prevent its re-occurrence. In addition, there are some simple lifestyle changes and DIY tips you can make in your home. These include:

Opening windows and doors to ventilate your home more efficiently

Using trickle vents fitted to double glazing

Using the extractor fans and opening windows when taking a hot shower

Always using the extractor fan in the kitchen and covering pots with lids when cooking

Drying clothes outside instead of on radiators where possible

How We Work

We are proud to hold the prestigious IICRC certification (Institute of Inspection, Cleaning and Restoration Certification) which means our customers are assured of the highest possible levels of cleaning and restoration work, delivered with respect, responsibility, integrity, excellence and expertise.

No Short Cuts

Contrary to popular belief, cleaning with bleach and water is not the solution to mould infestation, as bleach will not kill all the mould. Rather, it stimulates the mould to release of its spores, which further compounds the problem and increases the likelihood of the mould re-occurring.

At Causeway Cleaning Ltd, our trained mould remediation professionals use a combination of chemical products and mechanical solutions to remove the mould and any mould-bearing material carefully and correctly, so as to eliminate the spread of the spores. This prevents other rooms or areas from being exposed.
