This will help with the general odor but it won't penetrate the wood to kill buried bacteria.

Is there a lot of moisture on the windows?

We removed a large tree that towered over the roof causing a mess with falling debris on the roof and blocked all sun which left too much moisture.

They'll wipe down all surfaces, steam fabrics, moisture barrier in the crawl space, and put in a dehumidifier, if necessary.

I also hired Dwyer company to get rid of the moisture, seal-paint the walls that are in direct contact with the ground and install a sump pump.Here is the question.Do I need to disclose to the new renter (Section 8) that in the past, mold was present in the basement?

Any wall covering that is attached to the wall where water came in, IS going to be wet behind it (including insulation, if any), and the only proper method of drying it is by removing some/all of the affected area, or using a dehumidifier with tubes inserted between the foundation and the wall covering and high volume fans to quickly (it often actually takes several days to get all of the moisture out) and completely dry all of the materials.

i'm going to assume the blocks were filled with insulation which would take care of the moisture coming thru. 

Has it settled and allowing moisture in the 2' closest?" 

If the carpet needs to be replaced in the living room or other common areas, I'd recommend a very durable, moisture resistant flooring. 

There is significant damage to the upper and lower unit on one side and wanted to see if there were any suggestions for water monitoring/sensor systems that can be placed around the house and even in walls to monitor and alert you of moisture in those areas.
