John and Sally Tams, Nether Heage, Derbyshire

Dear Rob,
Huge thanks to you, and all the derwent sash windows team, for a brilliant job. The work is a 110% perfection. The team who did the installation worked diligently, courteously and to the very highest standards of workmanship and craftsmanship. We are all delighted with the way you have transformed out home.
