I'm working on a house for resale. After removing the entryway carpet I found hardwood floors in pretty good skape. However, the are two strips where the seams and butt joint are damp to the touch and the only water source close by is a hot water baseboard heating register. But the copper pipe from the heater goes down under the floor. I can only assume that there might be a pin hole leak in the copper that when under pressure releases some water.
Problem is... the ceiling below is completely finished in so there is no access to the heating pipes. In fact I can't even be sure this is the cause but its my assumption.
I'm writing for suggestions as to what the best method for repair would be?
I'm thinking if I cut one end of the wook strips which are in a hall closet I might be able to pull up the two wood stips. But, there's got to be a subfloor unther the flooring stips. I supposed I could cut out a section of that to see if I can see the pipes, etc., etc., etc. You get the picture b now.
Any suggestions as to how I could approach this problem? Thanks
