Where radon gets into a basement
The EPA lists cracks in solid floors, construction joints, gaps around pipes and sump pits as common entry points (EPA guide). Basements sit against the soil, so gas has many paths.
Slab cracks
We seal the large ones.
Floor-wall joint
A common gap where floor meets wall.
Sump pit
Needs a sealed, gasketed lid.
Floor drains
Check for traps and caps.
Pipe gaps
Seal gaps around pipes.
Open block cores
Check with a pro before closing off.

- Plan on paper We choose a route that avoids damage.
- Pick the suction point Usually near the middle of the slab or at the sump.

What helps and what does not
The EPA says sealing alone is rarely enough, but it helps a fan system work better (EPA reduction guide). Opening windows is not a long-term fix. See radon systems in Columbus Ohio for the full picture.
Questions people ask us

Yes. Water and radon are separate issues.
Do I need to remove my finished walls?
Usually no. We plan a route that avoids it.
Where does the suction point go?
Usually through the slab, or at a sealed sump pit.
Will sealing cracks alone work?
Rarely (EPA reduction guide).
Do I need to fix a radon problem in a walkout?
