We've lived here since 1975 and our brick extension has gradually been moving away from the house. The crack had reached the stage where I could no longer ignore it. No local builder was interested. Uretek came up on the internet while I was searching further afield. Though sceptical, I contacted them and I've been very pleased. The extension was surveyed and I got a fixed-price quote without any sales pressure whatsoever. I knew a small inspection hole would have to be cut in the floorboards but I had a panic when I found I would have to arrange that myself because I was unsure of the requirements, but I need not have worried. All the people who did the work, including the sub-contractors who surveyed the drains and repaired the damaged one - which seems to have been the source of the problem - were first-class in every way. Although I understood they could only stabilise the ground, they actually lifted the extension, significantly closing the crack. I also expected the paving to need complete re-laying but the disturbance was kept to a minimum. Other reviewers have suggested that this method is expensive, but since no builder has ever given me a price, I have nothing for a comparison. At one point before I contacted Uretek, I remarked that I would give a certain some to anybody who could just wave a magic wand and they did the next best thing, with the price being almost exactly that sum, including the VAT. Only time will tell, but I'm a very satisfied customer.
