The rug was cleaned in the lounge, and it sat on a carpet. All looked fine, but 4 days later it had bubbled up. It seems the carpet or underlay underneath has bubbled up with bubbles perhaps 2 feet long and 6 inches wide. They stand perhaps half an inch high.

I have spoken again to the engineer in question who performed the work and he states there to be bulging and rippling of the carpet around the rug before he started working. He should have bought this to your attention and we have reminded him of such. We are still pretty sure that no damage was caused to the underlying carpet by the procedures used by our technician.
