It's a house that is suffering from a bit of subsidence, funny thing is I filled that crack bout 6 years ago and at the time I thought it was a bit suspect as there was various cracks around the property inside and out, corners of windows, above doors etc, since then it has got worse more cracks, windows not closing, doors jamming,the woman of the house contacted her insurers who in turn called upon a structural engineer who has been monitoring the cracks for 18 months, and it is subsidence, we started on it last week, and it must have moved bout 3-4 inches at the worst point, the owner has moved out for 8 weeks, the pilers start on Tuesday, the joys of subsidence??. The women of the house is worried her house will fall down, but to be honest it's not the worst one I've seen, shame really, but as long as there is subsidence an my boss keeps his tendering pencil sharp hopefully I'll always have a job lol
