After visiting my property, I was initially impressed by the gentleman who promised to quote, but have since heard nothing, in spite of more than one request to get back to me. Very disappointed

Came the same day as i posted the job and was very helpful. Payment was not wanted until i was completely satisfied with the work. The job was started next day and at the end of the day the garden was left clean and tidy. Information and advice was given but no pressure was applied to do more than what was needed. The job was finished a day later to a great standard and looks fantastic.

I would recommend Andy. He spent time evaluating the job required with a view to looking at less costly but effective options. Most of the time I was out at work, he called everyday when he was leaving to update me on progress. He communicated clearly and so there was no confusion with what the job involved and the final cost. He was also very nice to my dog. Thanks Andy.

John and the team did an outstanding job. It was easy to work with John and he was very knowledgeable, and provided very sensible advice. Other people quoted work which was over-the-top or wouldn't have solved the problem but John got right to the issue in a no-nonsense way. Quality of the work undertaken was very good, considering the age of the building and complexity. Would recommend.
