Sean was excellent - highly recommend him. He was very polite and stuck to his quote despite the job being more than he had bargained for and taking him a long time to do... He was very conscientious and delivered great quality. Only slight fly in the ointment was difficult to contact at times which may be due to poor mobile reception where he lives (landline alternative might help). Would not hesitate to recommend and will be using again v soon!!
