I recently bought a 1940 house. The previous owner put an addition on in approx 2002. The new addition is not ventilating in the crawl space.
I put down new oak floors to match the original floors in the addition. They have started warping because of moisture in the crawl space. I installed french drains but i do not think this is working since it is still damp in the crawl space. Do you have any ideas for fixing this?
I have had 4 contractors look at it and none were experts on old houses.
