The ’Symphony Bygone Collection Sliding Sash Windows’, including ’Full Timber Jointing with Super Slim Meeting Rail’ surpasses all our expectations of a UPVC product: the appearance is that of a timber window, which compliments our stone fronted property perfectly/beautifully – look sensational!!. The bespoke hardwood door, made by Rob, painted in Manor House Gray (Farrow & Ball) and Off White, is stunning: we left the final design with him and are absolutely delighted with the finished result – the effect is GORGEOUS!! (If you need a custom made door then Rob is your man.) Both the door and windows were installed with internal period architraves and stub cill in natural timber finish, which was the ’deciding factor’ when selecting Derwent Sash Windows. The full installation was impressive: a highly professional/skilled team were thorough from beginning to end (they covered up absolutely everything before starting work); their attention to detail was impeccable during every part of the job: installation of all the products was completed to a high standard. If you want the appearance of a timber window without the maintenance then look no further: my husband and I can highly recommend Derwent Sash Windows.
