The basement in my 98 yearold house is musty. In spring there was a sewer backup. I moppedwith bleach and run a dehumidifier constantly. it's a 15 by 10 concrete basement with no windows, but a fresh-air intake. There's a four foot high crude entrance to a dirt area underneath the kitchen/bathroom addition on the main floor.
What's the likely source of the mustiness?
What tips work for drying the air out?

I wish I knew the answer to your problem, since I have basically the same question.

In my case, it's a 50 year old house with block type walls. I have a persistent musty odor which I suspect might be coming from the floor sewer drain. Also, I have a certain amount of run-off resulting from large trees whose roots have raised the ground surrounding the house.

Still, despite the dehumidifier, I have the smell -- even though there's very little visible dampness anywhere.

Just some food for thought for you, although I wish I had a better answer for you.

Check all plumbing water lines and drain lines. If water is leaking into the dirt crawl, then you may not notice it right away. You don't need a plumber to make this inspection, if you follow my instructions: Take several clean paper towels and run them along all water supply lines. Dry wipe all the fittings(tee's, 90's, 45's, etc.) look at the paper towels to see if they are wet. Fixture Drains: Plug the sink, tub, etc. Fill almost to the top with water. Release the plug, and go down into the basement to check for leaks. Inspect where these drains tie into the main house drain (This will be a small diameter pipe going into a larger diameter pipe via a tee or wye fitting.) If you have to get into the crawlspace kneepads are strongly recommended. If your not able, or still not sure, then call a friend to help you out.
