Excavate the foundation; reseal to prevent further water intrusion. ( I was in the basement and I didn't notice any water or a moldy smell). 2. Repair/cracked garage foundation 3. Repair the sinking driveway slab. 4. repair the drain valve and then 5. defective paint. If anyone can can help me out, I would appreciate it. Ty = )
