i recentlly bought a house. my basement is humid and smelly in the warm months and i am thinking of finishing it. i bought a humidifier towards the end of the warm season which filled up daily but smell remains in warm months. later on in the cooler months i also extended the
leader/downspout further away from the house, and have cleaned the gutters periodically since i bought the home.
i bought the house from a co-worker who i still work with. she had told me that she had minor water twice in 5 years. once in such a severe storm where many people i know never got water in there basement, ended up getting water in there basement, another time was also heavy and long term rain. these affected only a very small portion of the basement with just a film. i do have a concrete block/ cinder block foundation with a small portion of effervescence. i have been here around 1 1/2 year to 1 3/4 years with no water. what should i do before and during finishing the basement?

First Id work on keeping the basement dry! Water proofing from the outside is best but can be costly. Make sure land slopes away from home and make sure down spouts run at least ten feet. You are in a green grass state so at least a 70 pint dehumidifier should be run from April to October. A ninety pint per day would be best.

I bought a home and was the same thing happens to me when it rains a lot. I have cinder block and it was falling apart when I bought the home. I scraped and wire brushed the whole wall to get as much lose block off then patched the wall. I then bought waterproofing, forgot the name, and brushed 2 coats on. This has helped dramatically w/ water coming through the walls, but now I have water coming up from the floor. There are a few cracks and it seeps up threw them.

If you are planning on finishing the basement I would spend the money on a french drain w/ a couple sump pumps. This could save you thousands of dollars in damage in the future after you finish the basement off.

Good Luck
