Kitchen Fitting- 8 Mar 2025
Spoke with Contempo and they stated they would be able to attend to do the job that evening as they would be in the area, they arrived at the time stated and carried out the works there and then as required and expected. Provided a demonstration of the fan working and also installed the cupboard door to the face of the extractor unit. Cleared up and charged the amount that was agreed. Great, reliable and professional service.
