Instead of a defined spot you’ll have a discolored patch that’s now soaked in.Every few years I rent a gas powered power washer from Home Depot to clean my driveway, sidewalk, and back yard stairs.

I could not imagine how cold it must have it been for her during the winter and when it rained, things at her house must be soaked and yet...because she did not have the money to solve the problem, she was forced to live with it.

We have never borrowed money from family before.I'm extremely excited to have found this website and I am looking forward to soaking up as much as I can from you.

Long story short, major water damage, abatement, and having to replace 2 sets of kitchen cabinets that soaked up all that nasty water.

This thread is a bit old, however as the first responder suggested I've seen and heard many times the best suggestion is to use Kilz on the subfloor, of course replacing the bad soaked through sections.On Tile - I've personally used baking soda/water and a scrub brush - was time consuming and hard on the back, however rubbed the baking soda with a bit of water into the grout, let it sit for 2-3 days, then came back and cleaned the baking soda up with water and a final cleaning with another cleaning solution - good as new and no smell.Guess it would depend on the severity of the problem for the solution.
