Wouldn't even recommend to my worst enemies.
Did the landscaping for my pool, if you can call it that.
While cutting the stone, he cut the line to the waterfall causing a leak. After dealing with the pool company he finally came back to fix. His solution was to wrap the cut in the line and not repair it. Shoddy work which will fail.
Built a retaining wall without burying any levels/stones. Just laid the stones on top of the gravel. After one season the wall started to fail with large gaps noticeable. Again went through the pool company. His response was that its not his fault. Pretty sure even some who doesn't claim to be a "professional" would know that a 3ft retaining wall built on top of gravel will not hold back a pool and 150 sq ft of decking.
Fought with him for three years to get it repaired. Always blames someone else and says "take me for my word, I will make it right."
He didn't put any edge support down on the flat level interlock and that is also starting to fail off at the edges.
Don't really know what to say about someone who blames everyone else, doesn't show up as expected, and doesn't seem to be able to lay stones or build a retaining wall. A joke of a "man."
