"His quotation was the most detailed - breaking down costs so we knew exactly what was covered.

He took time to thoroughly understand our requirements and the comprehensive quotation reflected this. The work took longer than originally anticipated but for reasons beyond the company's control. We only had a few teething problems that were always quickly sorted out.


Dave was also very helpful when asked for suggestions and would suggest alternatives to us. We would wholeheartedly recommend Dave to anybody and we would definitely use him again."
