Seamus was very competent & fair. Adaptable & encompassing with the challenges the job threw up ! Keeping me well informed including realistic quotations at every changing situation. Good communicator/s with video and photographic viewing and examples, which gave me confidence as I wasn't an 'on-site' client. Highly recommended.
