Update: apparently they believe in retaliatory practice, they left the square patch in front of my patio uncut last week. Tried calling, no answer.
Summary: They blow dirt/debris onto your patios and don't care, even after being approached. I would not trust them for anything as this shows their true character.
I politely approached the guy in charge and showed him video of the landscapers blowing debris onto my patio instead of off of it. It was like this for the past few weeks. This week they just didn't even come back to clear it after throwing up dirt, mulch, grass and leaves.
I find it pretty wild that these landscapers don't have the attention to detail to know that they should be blowing debris into the grass, not onto people's patios. That is the point of them walking around with those leaf blowers I would think. I can only assume they are lazy and looking to "get the job done" as fast as they can.
