Oh my...I feel so bad for you!!!
Just reading this post is getting me anxious again. Last August 25, I woke up to the sound of a waterfall...the waterfall was water pouring into the finished basement (from the main level) of our brand new home! The supply line under the sink in our laundry room popped out during the night. Both our main level and our basement were destroyed and we had to live in the upper level bedrooms with no kitchen or laundry facitlities for 2 months! Even when insurance covers a water issue, they are extremely unfair in what they will cover...like a hotel!
I still worry about mold...it took Service Masters 2 wks. to gut and dry out the house, but the sheet rock in the basement wasn't replaced. The ceiling was replaced, but not the walls. We were assured that we wouldn't have to worry about mold because it was thoroughly dried out, but I'm still nervous. Mold issues are overwhelming!!! So sorry you have to go through this!
