Solomon replied to my ad very quickly which was great and he managed to get the heating working in my flat, which it hadn't been. However, the fault light on my boiler came back on shortly after he left and he hasn't been able to provide a report on what issue needs fixing for me to be able to follow up on. He also wouldn't pre confirm an hourly rate or agree costs upfront. He was however very friendly and helpful, if he can provide a report and rectify the issue then I'd happily use him again.

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.
