I have read many of the posts here, but would like some advice on a couple of things. I will be installing a drop ceiling system. The cinder-block walls were painted with dry-lock by the previous owners, but there is a good amount of that sloughing off on the lower 2ft of the walls. A couple of years ago I cleaned the walls and used an "etching" solution that dry-lock sells. After repainting it, it is coming off again. So I am not going to bother again. The basement has been dry for over 5 years now after I took steps to repair downspouts and buried 4 foot of stone in all of the window wells. My main sewer drain in the basement goes around all of the walls, so I am offsetting the studs by about 7 inches. I am using P/T on the bottom. I plan on installing R19 kraft faced between the studs with no plastic. Since the walls are 7 inches out, I assume any moisture will evaporate (I have a dehumidifier on auto setting to keep the air dry). Here are my questions: Is there any reason to insulate the floor above? Since I am 7 inches out, what is the best way to "box" in the windows to still allow light in? Also, I have a crawl space with an opening of about 3ft by 4ft under a laundry room. I want to seal it because it is very cold in that crawl space. But I still want to be able to get in there if I need to. Any ideas on how to do this and still have it look nice? I guess I could put in a door even though half of it would open to a wall. I have two pillars holding up a steel I-beam. I once saw some wood product to wrap around them to make them look nice, but now I can't find anything. Any ideas besides boxing them in? Thank you very much for any ideas.

My basement is flooding.The warter seems to be coming from between the block walls and the floor.What should I do?
