for litigation matters, everyone will want to see the issue first hand so be prepared to have the conditions linger while everyone gets up to speed and comes to see what happened. guilty parties tend to drag feet so the sooner you inform everyone, the faster the cleanup. And as stated above - "everyone" means your insurance company and the company that did the work. Standup companies will fix the issue and resulting issues on their dime in which case your insurance company will just close their claim. More often than not, the guilty party won't fix all they are responsible for, drag their feet, or not even respond but you want to make sure you give them the chance to make things right and/or see the problem for litigation arguments later. If they don't respond or drag feet or don't do all that is necessary to repair, your insurance should pay for repairs and then subrogate against the company that caused the problem. subrogate is just a fancy term for sue them on your behalf to get your insurance company's money back. absolutely keep every document and take pictures. you can't possibly take enough pictures. if you think you took too many pictures, take 10 more
