Seal the grout to keep the dirt out.

I walked into the kitchen early this morning and said:"Well, I'm sending the emails to seal the deals - when I hit ENTER, your life is going to change."

If the stone foundation was sealed and more concrete was poured that would help but there is no guarantee that it will lower to EPA standards.  

Last one is to seal concrete slab gaps on walkway and driveway.for the big job, it's for a rehab for a  house were closing on - new floors, move walls, trim, paint, new appliances, cabinets, landscaping, and more

It was our residents complaints that sealed the deal.  

But let's say you replace windows and seal the house up, then this heater could become deadly. 

I find that helps seal the deal too.

Would sealing the edges of the foundation (pics below) with drylok or some other sealant prevent the water from getting into my rooms in the future?

He showed me a spot above the garage door where he proudly told me it took him 3 coats of paint to cover the water stains.It turns out this whole community has a builder defect that involves the fascia and the sealing of the "envelope" - still not sure what that means but basically water has encroached in between the masonry and the concrete block and staining is noticeable over the overhead garage door and only on that wall.

Unless he is living in a sealed bubble he's going to have to deal with it wherever he lives.My first realtor was sensitive to mold.
