- Mrs C Robertson

Andy & his team are professionals, turn up on time, keep you informed at all stages and ensure the job is completed to the best outcome possible. We had two other companies in before Andy, both were unreliable and their work was of a poor standard. We called Andy in hoping ‘third time lucky’ and we were lucky, as the job, which was far from straight forward, has turned out fabulous. We wouldn’t hesitate to recommend Andy & his team and will definitely be using them again.
