I had a customer ask me if there was some reason why another LCO wanted to charge them over $2000.00 to remove the old lava rock from around their home (est. maybe two ton of L/R),and another $1500.00 to put in mulch. I'm i missing something? Is there a special way to get rid of this stone? They called me to give them a price of removal (of L/R) and install of mulch.
