About

If your home or office is making you sick we investigate issues which may identify building related illness or "Sick Building Syndrome".

Indoor Air Quality (IAQ) are often responsible for asthma, cold and flue like symptoms, memory loss, brain fog and varying complaints from hair loss to skin irritation.

Water damage from leaks or flooding can result in biological amplification in only 48 hours and mould, bacteria and even chemicals from wet construction materials can affect your health.

We investigate all parameters of IAQ from building design and construction defect to water damage, fire and general ventilation issues.

We are qualified and certified Indoor Environmental Hygienists who are members of Surviving Mold IAQ group. We are members of SM medically clean environmental group of IEPs focusing on CIRS and Environmental Illness support.

If you're suffering new or worse health symptoms that may be related to your building, recent repairs or damage give us a call. You are not alone!

After my girfliend had suffered debilitating health issues for years due to mould hidden behind inner plasterboard walls, Julie and the team at building forensics carried out a survey on our place and were flexible to support us last minute. They have been invaluable ever since. We were recommended by a friend who had also been sick due to mould, and we are so thankful to have found this company. Julie and Jeff have continued to provide support in our next step to find a new home and advice to help my girlfriend. They provide us with guidance and support throughout and would even offer refunds for items we wouldnt use. They are a great company, and we will certainly be using them again. Highlighly recommend! Thank you Jeff and Julie!

After it was suggested that years of various chronic health issues might be caused by mould in our home we contacted Jeff to do a survey. He was extremely knowledgeable and did a through survey giving us information on the main problem areas and how to start getting our house back to normal. It has been a challenging time and we still have a way to go with it but it has been very reassuring to know that Jeff is happy to give his expert advice whenever we need it. Worth every penny and I would highly recommend.

A national treasure

After a lifetime of health problems, and more recently acute health issues including IBS, a kidney infection, and a bipolar diagnosis, I sought care through a functional medicine physician. She determined that I had mycotoxin (mould) poisoning and instructed me to carry out mould testing of our new home. Not surprisingly this illness and corresponding field of doctors, environmental consultants, and remediation companies is in its infancy. There are few if any companies in the UK that truly understand how to properly handle mould in the home. After extensive research I came upon Jeff Charleton’s background and business and immediately got it touch. He’s renowned in the US amongst the top mould specialist, and is a national treasure here in the UK. If you’re lucky enough to get him to come to your home you will be certain to get the clearest picture of what’s exactly going on and how you can fix it. He is an endless wealth of knowledge when it comes to combating mould in the home. What’s more, he’s not alarmist like many other professionals in the industry, which is reassuring and greatly appreciated when one is dealing with sick building syndrome. He also offers loads of additional support and guidance, which easily justifies his fees. I began working with him this year and plan to continue to utilize his services until our home is remediated and my mould levels are under control.

I first called Building Forensics as I needed some advice on the mould I had been dealing with in my home for the past decade. Jeff was exceptionally helpful and gave me so much advice just off the bat. There are not many people who genuinely care as much as Jeff does with complete regard for people’s health. I ended up needing Jeff’s service in the end, and he was professional and efficient and has provided me with endless support. I cannot rate his services enough, and not to mention his CV, there isn’t a more qualified and accredited person in the industry than Jeff. I am utterly grateful to him! Outstanding service I will recommend to all friends and family!

Unsatisfactory customer service, unanswered questions, no confidence in trader

I contacted Building Forensics after my Functional Medicine Practitioner advised to use them for a mould survey. - Paying a over a couple of thousands of pounds for a report you expect it to be correct and arrive in a timely manner, instead I had to chase the report - which had supposedly been emailed but never arrived. - There were some glaring errors (name and address for one) on the front of the draft report. An assumption made by the technician was concerning, mistaking flat roof drainage points for loft vents, although this was pointed out it was refused to be removed by Jeff. This is Jeff that didn’t visit the property but produced the report. - I asked if I could talk through some of the questions and was told I had to email everything to Jeff. - Several pages didn’t make sense. So I prepared a straight forward list of questions regarding each item. The reply, when it finally arrived, was a brisk single sentence which often didn’t answer the question. - I sent a further request for information and again received a brisk response that didn’t answer all the queries. There is lots more I could say. I feel duped and have no confidence in the report I was provided with, the insistence by someone that didn’t even visit the property that I have an airflow problem in the loft when I provided evidence that I don’t is galling. I ended up getting a second opinion and treatment from a competitor that excelled. I would not recommend Building Forensics.

A Which? Trusted Traders staff member replied on behalf of the trader (on 22/04/2022)
Thank you for your comments and we are sorry to hear you were not satisfied with the service we provided. We apologised and rectified the address issue on your report, we also implemented procedures to ensure that this does not happen again. Whilst I did not physically attend the site, my trained technician collected all relevant information in a template format which I require and together with data from the labs I am able to provide a detailed report. I appreciate the reports can raise questions and whilst being on my holiday in Spain, I responded to the 2 pages of questions via email answering all questions and three purpose written guidance sheets on best ways to proceed with remediation, were also provided free of charge. The report was sent within the 2 weeks stated at the beginning and all emails responded to within 1-2 days. These emails have been shared with the WHICH review panel to verify the dates, times and attachments shared. If you have further questions, please send by email and or send directly to Which? to ensure transparency.

Jeff came down to Devon to do a survey on my house after it suffered storm damage which led to water penetration in February twenty twenty. Jeff did a very thorough survey which found and highlighted many issues within the property caused by the water perpetration. His very professional and extensive report regarding the issues was passed on to my insurance company, giving it a very clear pathway for the remediation. Jeff was very professional and helpful. These also apply to the wonderful staff in the Building Forensics office. I highly recommend Jeff and this company. Great service. Thank you.

I'm a functional medicine practitioner and naturopathic nutritionist. Last year I discovered just how seriously mould can affect your health and enrolled in a course to become a mycotoxin practitioner to learn not only how to treat myself but also how to treat others, having realised that my body was full of these highly poisonous toxins coming from the mould in my home which my landlord had ignored. Several other mycotoxin practitioners all recommended Jeff as the most if not only knowledgeable building inspector in mycotoxins and mould inspection. When I first contacted Jeff, it was clear he was very knowledgeable from the mycotoxin training I'd done and he explained that the half-hearted attempts to remediate my property that my landlord had carried had in fact made the issue worse. I was terrified they wouldn't find the source but they found multiple sources, some of which were completely invisible, and wrote a comprehensive report which gave me the ammunition to hold my landlord accountable. Jeff amusingly admits on his own website that he can be grumpy at times but if ever you experience that, do not let it put you off, he is extremely knowledgeable, has a heart of gold and really cares about getting an outcome for the person being affected by mould sickness, having been affected himself. I recommend them to all my mycotoxin clients now and Jeff continues to be a support in terms of my dealings with my landlord in trying to get the property remediated.

Turned everything around

Building Forensics came recommended by a friend in a similar situation - bathroom leak; significant mould behind tiles unsafely dried by a contractor; family members with health issues making them more vulnerable to the effects of mould, and difficulties getting our insurance company to take the matter seriously. Building Forensics turned everything around for us. Their report triggered our insurance company to escalate our claim to the highest level and to provide safe alternative accommodation for our family. Despite lockdown delays, we are soon to have the mould removed under safe conditions. Jeff Charlton is very knowledgeable and has been generous with his time, especially when we were floundering around not knowing which way to turn. So glad I took my friend’s advice!

Thank you Jeff and Sam for all your help and advice. I contacted building forensics due to some mould growth in our basement. Although we didn’t have any health conditions related to this I knew of the danger of mould. Having young children we wanted to have a clearer picture of how bad it was and what we could do about it. Sam did a full investigation in all areas of the house. He explained in detail each test he was doing and made suggestions on extra tests we could do when he felt they were necessary. A week or two later we received an extensive report covering all the investigations, the consequences of the findings and recommendations of what to do. It also included valuable information about different aspects of mould and air quality. The survey itself was extensive and but in some areas too technical for us to understand fully. We asked to speak to Jeff to go through some of the points to have a better understanding and he was more3 than happy to help us further. Jeff spent quite a while on the phone to us going through the survey in more layman terms and making sure we had a full understanding of our situation and the next steps we needed to take. Jeff and Sam are real specialists in this field and are the ones to go to if you have any mould related issues. It is not a cheap investigation but this is definitely worth it if if you have any mould growth in your home as the affect on your health would be far far higher. I highly recommend Building Forensics.

Jeff knows his stuff. He explained exactly what needed to be done, following an inspection survey and continues to provide invaluable guidance in dealing with insurers and their appointed contractors. He operates in a complex area where many do not understand the synergistic effect of multiple contaminants on human health, yet Jeff simplifies the issues and suggests an approach that minimise costs and avoids unnecessary activity. Sam is professional, focused and diligent. It's made a huge difference to us, while getting our contaminated home sorted out, to have the expertise, experience and savvy of Jeff's input. If we hadn't called him, chances are that we would have had our leak repaired and redecorated and would still be living in a toxic property without realising that was causing our health issues.
