  • Well after being quoted by another company who failed to turn up for the work, the guys at Sash Window Preservation were quick in getting their quote in and creating time to get the work completed (even working some weekends). The sash windows rattled and were draughty, but now thanks to the guys we have windows to be proud of.
    — Mr & Mrs Rose, Norfolk
