We have sky high snow plowing service for our low rise apartment building.
They show up late in the evening, when all tenants are at home and the lot is full of cars.
They drive through once and don't return to follow up.
They are also required to clear sidewalks and steps, we have to call them over and over again after every snow fall to remind them of work to be performed.
I would never, ever recommend sky high to anyone for any kind of work, ever.
Stay Away....very poor service
