Sorry to watch the flooding in the UK on the TV over the last few nights.
It's one of those things where regular customers will ring you but most other people will ring the insurance company.
We've had one major flood this year and we were up the walls sucking water out and cleaning hard flooring after the event. It's lucrative work but in a domestic situation you meet people in the worst of conditions, unsure what to do, where to go..... At least in commercial premises the staff go home at the end of the day.
The smell is the worst thing and probably the hardest part to deal with (especially river/sewer flooding - burst pipe can be OK if you get there soon enough).
