The hardwood is pretty rippled in about a five foot square area. We're leaving it to dry for several weeks and see how much it flattens out before deciding how much work it will need. If we're lucky, a light sanding and coating will be enough. If we're unlucky, it means replacing the whole floor. EEEK!!
The outside of the house will have to be painted, too. The brown stain doesn't come off. I tried on parts of the windowsill already.
