The WHITE KNIGHT solution will always be proportional and appropriate for each individual circumstance. 

If I see mould what should I do? 

Visible mould in an indoor environment is a strong indicator of either a previous or ongoing water intrusion. Moulds are ubiquitous, which means they can be found everywhere; it’s natures way of recycling waste materials, but issues arise when the amount of mould in an indoor space increases exponentially and has an effect on the building fabric and the human body. Try not to distrub the air around any visible mould as the spores are very light and can cross-contaminate other areas of the property. Call Phil for an informal chat (there's no charge) on what you can do or how we can help you. 

Self help 

Wear an FFP2 painters mask 
Cover the affected area with plastic, and tape the edges firmly with duct tape until a proper assessment can be made 
Open windows and doors if possible, to allow better airflow and air exchanges to occur 
Turn on bathroom/kitchen extractor fans 
Don't use bleach or spray the mould with anything as this can release spores into the air and make matters much worse

I feel unwell at home but nowhere else, is there a mould / indoor air quality issue that requires investigation? 
"Hi, this is Phil. I never recall having any mould/allergen/pollen related issues myself as a younger person but about 15 years ago, I recognised significant respiratory symptoms when being in areas with high levels of microbial activity. Despite wearing the best quality PPE and respiratory protection when performing mould surveys and mould remediation, there have been numerous situations where no visible mould was present and therefore I haven't been wearing any PPE, exposing me to higher levels of invisible contaminants than my body could tolerate - in these situations, I have ended up wheezing and have had to grab my respirator. I'm now a cancer patient and so I fully understand the health concerns you are facing but there is light at the end of the tunnel, there are incredible advancements in technology that WHITE KNIGHT have invested in, that can return your home and possessions to pre-incident condition"  
So, just because you can’t see mould, it doesn’t mean it isn’t present. In summary, if you are feeling unwell at home or work with symptoms such as respiratory issues, allergies, asthma, sneezing, a runny nose, red eyes and/or skin rashes, it could point to a mould or another indoor air quality issue that requires a full investigation and air sampling.

Is this something I can treat myself or should I call in an expert? 
Unfortunately, the mould industry is rife with unscrupulous scare-mongerers who use bogus qualifications like "Indoor Environmental Hygienist" and bunkum science to prey on people who have health issues or a fear associated with mould. In the USA their motto is "Mold for Gold". We advise that you do your very best to avoid companies or individuals that come across like this and use companies who have your best interests at heart.

Honour and integrity are at the core of our business activities, which is why we retain so many loyal customers.

Can you advise on my health issues? 
I know firsthand how lethargic and irritating the inflammatory response to mould overexposure can be but I'm not a health professional, so I cannot advise on your personal health issues - anyone who advises that your health concerns are attributable to a water leak or mould activity in your property, without proper investigation and analysis doesn't know either!  
Globally there are NO standards for what constitutes a health concern in relation to mould exposure or indeed, any agreed standards on how to effectively treat mould. The WHO (World Health Organisation), regulatory bodies such as the US EPA (Environmental Prorection Agency) and indoor air quality associations offer simple guidance in the form of "remove the mould, and fix the issues causing water ingress".  
Fortunately, as Indoor Environmental Professionals| with many years of expertise in sampling, testing, analysing and removing mould, we can review your individual situation and needs, and write an effective mould protocol to fully resolve your issues. 
How can WHITE KNIGHT help me? 
At WHITE KNIGHT we’re genuinely interested in helping YOU to improve YOUR living conditions and hopefully this has a positive impact on your health too. We take a holistic view of all the potential issues that can cause long term damage to properties by moulds and fungi and follow industry 'best practice' to achieve the desired outcome. 
How much does mould remediation cost and is it covered by my insurance? 
Structural damage caused by long term water ingress and microbial activity may or may not be covered by your property insurance - it will depend on the source of the problem, your insurer and how your insurance policy is worded but with the unknown health risks and associated property damage costs, it makes good sense to get an expert opinion and report to help your case. When it comes to genuine health risks, we really believe that people shouldn't take chances, and we are here to help. Mould remediation doesn’t typically run into tens of thousands of pounds but it isn't always a quick, cheap and easy problem to fix properly. An Indoor Air Quality and Moisture Survey is only £695 + vat and our comprehensive photographic detailed report will provide results, conclusions and recommendations that you can submit to your insurance company for approval.
