We are absolutely delighted with the newly installed Ultraline sliding doors and windows in our self-build home.  Every single person we have come into contact with at DWL has been a pleasure to deal with.  The process to ensure that installation ran smoothly involved a site survey, which was extremely helpful for our build team and ensured that they knew exactly what was needed.  Nothing was too much trouble for the installation team and they coped admirably with a tricky access route.  DWL were absolutely true to their word with delivery dates and went above and beyond to meet a date by which we needed the doors installed.  A five star service!
