My wife works for the insurance company so I am quite comfortable with our ability to get attention as required. Both during and following the event. The company has been good.
It was a toilet that broke. Not the expected supply line (which I replaced with a braided line 10 years ago when we moved in - did that in all the bathrooms at the time - I will look into those safer supply lines too). The tank actually cracked and that allowed the water to run from about 9am until 3pm (or at least that is how long I was out of the house). Rare for a toilet to bust I know, but I can tell you I did not do anything to it, and am doubtful that either of my daughters (9 and 11) did. It was 19 years old, original to the home.
They tested the entire drywall ceiling for moisture, and pulled out beyond what was affected. There will be a little more pulled down, as there has to be a stud or joist to hit with the new drywall. The wall removed was only partially affected too, they removed the entire tile bathroom floor, vanity and toilet. I had them in my basement checking walls and ceiling with the moisture probe, I am not moving (OK, I have an 18-20 year plan for this property and will move then) and I do not want to deal with mold for sure.
The leak is 100% solved for sure. New American Standard toilet waiting in the wings.
The actual drying was done 5 weeks ago. I saw the readings during and after the drying process and am satisfied. I had pushed for further remediation, but trust the readings I saw.
It took a subsequent amount of time to reach an agreement with the insurance company around the $ figure etc. That is settled now and I am forging forward.
Electrician done, drywall repairs begin Thursday. Main floor should be back to normal in 8-10 days. Bathroom will lag as I am having trouble finding subs (and of course the good ones are busy, so i am willing to wait).
