About three weeks ago when you walked into one of our bedrooms there was a wet spot it kept getting bigger then we had a huge leak in our front yard plumber came out fixed outside first then that wet spot in our bedroom just dried up now its back and much worse its in that one room,hallway,and master beedroom no sign of leaking pipe my husband checked our water meter and the meter was going and we were not using any water is that a busted pipe under concrete? And why did it stop for a week then come back and how much will that cost to fix? How long does it take to get mold from water damage or get sick
