Flagstones and asbestos

The builders are back to re-lay the flagstones which were taken up to mend the drains. The previous layout was a mixture of flagstones, tar, concrete and anything else previous builders had by them. There aren't enough flagstones to cover the whole area, so we'll have to get some new (synthetic) ones and hope they don't look too naff next to the originals.
The roofers are coming back today to replace the asbestos roof on the back kitchen and deal with some other minor problems which are too boring even to put here.
Samples of insulation from the old heating pipes were sent for analysis and apparently do not contain asbestos. This is good news as it means that the old pipes can be removed from the cellars.
