This company provided an accurate, careful and courteous service in supplying and fitting double glazed windows in a number of rooms and replacing our porch. The after sales service has also been prompt and efficient to deal with the adjustments required from the inevitable settling of new doors. Quality service.

We moved to our bungalow 3 years ago. Our first job was to put a new bay window I'm so glad we chose marathon for an excellent job. We then had a conservatory and we are thrilled with the result. I can only speak highly of the workmen. Very professional. I would recommend Marathon to anybody.
