While the guys we hired worked on the floors I worked in the basement. The basement was leaking mainly in one corner, but overall it was very damp and dark. We decided to paint the floor and the walls. For the floor we used BEHR 1-Part Epoxy Acrylic Concrete and Garage Floor Paint and we used a moisture block paint for the walls. I thought about using 2 part epoxy on the floor, but the 1-Part Epoxy was much easier to use then 2-Part. We have had the epoxy on the floor for 2 years and it has held up well. I also fixed a leaky downspout and filled some giant cracks between the foundation and the driveway. I think this is where the basement leaks came from. After a few months or so of filling cracks and moving topsoil around I finally did fix all the leaks and the basement has been virtually dry ever since.
Back to the wood floors... as I said the workers where doing a great job, but disaster struck one weekend night. While the floors where being worked on we sanded ans stripped the stairs and the stair rails. After a long day of work, we left the house in the evening to go back to the hotel. The Floor guys where still in the house working away. The next morning we entered the house and heard this terrible noise. It turned out to be water pouring through the house mainly in the living room.
At this point all the floors have been sanded and there was lots of dust still in the house, and all the water made a big mess of things. It turns out the source of the water was a radiator in the master bedroom. The purge valve loosened it self out of the radiator and shot across the room. Water ran through the house for who knows how long. We can only speculate how it happened. Our best guess is the vibrations from the floor sanding machines wiggle the valve out, and the floor guys didn't notice the leak before they left.
We managed to clean up some of the mess with the help of the flooring guys and we called our insurance company, and they sent out a company. The company cleaned up the rest and dried the house out with a portable heater and lots of fans.
The water damage was significant we had to replace two ceilings, re-sand 4 rooms, paint 3 rooms including many wood windows. The insurance company covered everything.
I guess the most important thing to remember is if you have radiators in your house before you work with any large machines that vabrate significantly go around and tighten all the valves. It might even be a good idea to tighten them once a year. Below shows the before and after of the floors.
