Had the firm back around 6 times to cure the large bedroom window,twin opener with central pane.Right hand one draughty,noisy the fitter had no idea,I pointed out he needed to put a spirit level against the frame upright,where he saw as I did,that the bottom was around 12mm out.So when the window is shut it does not meet in the middle with the seal.He called again to rectify took the centre fixing out,packed the frame out and put a new fixing in.Now it does not close correctly from the top to half way down.the frame is obviously twisted,Whats the best way to go.Get another firm to check the issue and correct it,and bill them.Or keep on thier backs until its fixed.
