Hi, We have just had our loft done by Loft Life. It really was not that bad. I had a pre crawling baby and a 6 year old at the time and we managed without a huge amount of disruption. It can be noisy, especially at the beginning. As far as dust, the builders put down plastic covers over the carpet on the stairs and also sealed up doors on days when they broke through. There was still dust, but it contained most of it. They also hoovered every evening before leaving however I still mopped down as well to keep the dust down. The beginning bit before they break through despite being noisy is the least obtrusive for you as it's all from outside. The end bit is also quite easy, as final fit, and plumbing etc is quite contained in the loft. Obviously the plastering causes dust. However we found it dried quickly and as soon as we got the first undercoat on the walls it stopped the dust. PM me if want to know anymore. Good luck. It's great when all done and well worth the hastle!
