Customer Testimonials

I am pleased to say that The Sash Window Workshop have turned what might otherwise have been a stressful experience into an altogether satisfactory one.

At all stages your staff have consistently returned calls, kept appointments and provided an excellent and highly professional service.

The fitting team worked diligently and finished on schedule, they were meticulous and cleaned up afterwards.

The new windows are in keeping with the requirements of the Conservation Area, look splendid and are a pleasure to operate.

I would have no hesitation in recommending The Sash Window Workshop to anyone considering the installation of new double glazed units.
