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
