The new home I'm buying has slightly elevated radon levels. Can an
amateur do this fix. There is a sump pump at the corner of the full
basement. Can I use that as the source of pull with a pipe going up
the wall and out the side of the house? There are numberous small
cracks in the floor too. How do I seal them. Ultimately I will be
finishing off the basement for a family room, so I should do all this
now, yes?

Thanks
