Flood cleanup?

[winterhill.livejournal.com]

We had a sewer backup in the condo building which resulted in flooding in our shared basement.  Got an estimate from Service Master to clean it up but it was really high ($2700) and involved haz/mat suits and HEPA filters and rebuilding of the partitions between storage spaces -- basically everything but the kitchen sink.  I am not sure we need to do that much remediation but have no idea if this is standard or not. 

I looked through posts back to July 2007 but saw nothing about this.  Anyone have a recommendation?  Thanks in advance.
