Crown Systems

Crown Systems (they have two phone numbers: 727 815 0744 in Pinellas and 813 989 0796 in Hillsborough) appears to be a fly-​by-​night operation going through neighborhoods where the respective neighborhood association sent out their annual deed restriction letters trying to push their residents to do certain things to keep up appearances.
We hired them to clean our blackened roof with their «non-​pressure pure chemicals» technique (tried to avoid damage to our tile roof as much as possible…). They immediately asked for cash payment (probably to avoid taxes) for a rebate. Anyway, they came by and cleaned everything. After a few days, landscaping worth about $ 80 had died around the house, and much of the surviving plants had sustained significant damage (but seem to come back). On the back of the contract they give their customers, a grand «plant guarantee» states that they would replace plants in such cases for free. I called them and left a message. Without calling back they showed up at the house after a few days and cut off all dead bushes without further consent. Leaving ugly holes in our hedges, they left and were never heard of again. I left multiple messages to no avail. Phones are never picked up. I ended up replacing the plants myself. Bottom line: If you need to hire them, do not pay the full amount before about two weeks are over after the cleaning procedure. But in light of their unserious business practices, I would really recommend to stay away and hire someone else.
One more point: According to Google this «company» seems to be affiliated with a statewide operating Florida company named «Pressure King». I would assume that Pressure King follows similar business practices, i.e. be careful if you deal with them or their disciples!
