Firstly I’d like to mention the the repair was carried out professionally and quickly with great care and deserves specific praise. However, be aware that the initial installation by SWR is only covered with a 2 year warranty with no exceptions. I was informed when first fitted that this particular window was stiff to close because of the window seals. It appears from the technicians that recently rectified the problem was that the closing issue was due to incorrect original installation and a misalignment of the locking catches. My frustration is of course that it should have repaired by SWR with no changes to me as it was a problem with the original fitting.
