I don't have timber floors but when I was pregnant late last year with DS, I left the bathroom tap on & plug in the sink ALL night.. I only noticed as when I was walking down the hall the next morning, it had seaped through the bathroom into hallway and to my daughters bedroom. I called the insurance company and they were fantastic with in 1 hour a guy was there with massive industrial dryers which had to be left on for 3 days...

So my advice would be to get on to your insurance who will send out the professionals, who will know what to do....this guy was able to tell how much % of humidity we had in the walls and floors it was amazing...We ended up with no structual damage...so I would really recommend getting a professional out to advise you...

Good Luck!!!
