We used Kingz for clearance of a very overgrown garden and new fencing. They did exactly what they said they would do in their quote. They worked hard, left the garden tidy, and took away all the waste. They were very pleasant and Emma, in particular, gave good advice regarding ongoing after care of the garden. We were very happy with the results and would definitely recommend this family team!
