Sewage damage to townhouse rental

[Jennifer Christensen]

We had a toilet at our rental overflow (not exactly sure why yet) but it's caused around 6k worth of damage.

The disaster clean up company we're using has a de-humidifier that is making the rental over 90 degrees inside.

What kind of compensation would be appropriate for the tenant?  Do we owe her money to stay someplace else like a hotel?  We're not sure how long this cleanup will last.
Any help/thoughts would be very much appreciated!! 

Thanks
