I always charge an ispection fee for bat estimates....... 80-169 depending....
You have to seal ALL the secondary entrances first,,,,,on the entire building,, any gap 1/4 inch or larger will need to be repaired.
Primary entrances kneed a one way valve over them for3-10 days depending on weather ect......
Clean up is a different issue,,,,,,,, I can often get insurance to cover that...
Call if you want to, 360.224.6649,,,, OR AND IF,,,,, it is something you think you do not want to handle I work the whole state for bats,,,,,,,,,
