Great quality and service

We were very happy with the service provided by John and delighted with the quality of the double glazed sash windows. Our original leaded light units which were incorporated into the new windows look wonderful and should now last another hundred years.

Excellent, skilful service. John’s renovation of our sash windows stopped draughts and rattles, and reduced sound transmission from the street.
