It is difficult to guess as each application is different. However I
would suggest that when it is done properly it is almost always very
effective. The trick is to have someone who is knowledgeable and honest do
the work.

imho:
Each type has its own success ratio.
I found this, http://www.epa.gov/radon/pubs/consguid.html#installtable
it says subslab suction, low range it only 50% so you can get down to
4.85, which is still over the 4 action limit. So worse case it seems
that subslab suction will have to be used in conjunction with another
technique like sealing cracks and seams.
Good luck, please keep us up todate to yoru success.

Talk to your neighbors. Find out who they recommend, check with the
BBB for any potential contractors, and read the EPA site. I belive it
has suggestions about getting guarentees about a reduction level.
Good luck,
