The cost is $100 per hour with a $250 minimum. After we get an idea of the size and type of space, we can provide a better quote. Offices with multiple floors, cubicles, doors or tight spaces take longer than spaces that are open.

We can’t disinfect an area that has a layer of dirt or the disinfectant will not be effective.
