We are absolutely delighted with the work on our Tilt and Slide patio doors. From jammed and rough to as good as new. We were given a price on the phone and it wasn't a penny over. I firmly feel we have been saved hundreds by not having to replace them. I give Stephen Fretwell 100% and would recommend him.
