The team that installed my Anglian windows did not put the damp course back as it should be, just stuffed it back, and put in the new windows. Obviously it was time before this would manifest itself as a huge ingress of damaging water. It happens when there is a SEVERE storm, with the strong wind and rain coming at the house from a certain direction. SO NOT ALWAYS APPARENT FOR A LONG TIME. THIS MAY NOT HAPPEN IN THE GUARANTEE PERIOD This is obviously difficult for the female telephone operator to comprehend. The front, South facing, downstairs, three windows of the house were affected with water pouring in by the gallon. After I paid a structural engineer, who confirmed bad installation, Anglian took out the 3 windows on this South facing side of the house, then reinstated the damp proof membrane, and put back the windows. Result good, but needed a lot of cosmetic repair, but solved the (their) problem. The storm we just had, unusual in its direction, affected a window on the North side of the house, part of the same installation, causing large ingress of water, easily seen now with the stains coming down from the top of the frame, right down the sides onto the windowsill. They say we can't do anything. (A lame excuse) They say 'why did you not inform them before' They say an Act of God: I say an Act of bad installation by Anglian windows They say 'get a builder' !!! That admits their fault! I think I'll get a structural surveyor report, then perhaps a solicitor. Avoid Anglian, try Everest?, not sure. Friends use local small forms for their installations. Perhaps that would be better. Anglian obviously don't want to put the problem right, even at a charge AVOID
