Its very stressfull. The paperwork is unrelenting as you are dealing with loss adjusters and insurers who have strict timescales for visits reports etc. You are also constantly dealing with emotional people who have lost their homes and sometimes in fires have lost pets and even family members. I did it for 20 years but packed in last March to concentrate on my supply business. I don't miss it. Even though the rates have been slashed over recent years it can still be a good earner.
Training is essential as mistakes can be costly. If you dry a building and issue a drying certificate which is then re-instated and a few weeks or months later mould appears, if it wasn't dried properly the drying company is liable. That can mean a complete re-stripout and further drying. One job I got called in to sort out cost the restoration company £88,000.
