No there isn't. Like I say the building inspector did his usual turn up, have a cup of tea, chat to the builders, and leave. Do they inspect anything? Having said that he did insist the footings went down about twice as deep as the builders had dug them so maybe he just knows what t look for.
It's bone-dry under the polythene. I've also put a newspaper on the floor to see if it gets damp. After one night it's also dry.
Which, by chance, having come from a damp house previously, we have in storage somewhere. Never thought I'd be digging it out for a new extension though. I'm hoping that this is just damp from the building process and once it's all dry then it won't need any more drying out.
Today it smells fine. Is it a co-incidence that yesterday was bucketing down all night and day and today it isn't and yesterday it stunk of damp and today it doesn't?
