I cannot fault Wayne's approach to his trade. He quoted the job at a very reasonable rate which I cross-checked and accepted. He also offered to do the job in my absence and didn't insist I paid up front. The job was completed on time and to a high standard. Wayne kept me informed of progress and proved to be a reliable, honest and trustworthy bloke. In fact, I was that impressed that I got him to quote for another job; which was also completed to a very high standard.
