Exceeded expectations
Mark and the guys were on point from start to finish and the results exceeded our expectations. Full house Edwardian restoration; some double glazed sashes that were fitted into existing boxes (giving the same original 'slimline profile' finish we were looking for) plus a whole bay of brand new boxes too which look amazing. Would happily recommend to anyone!
