Depends a lot on how they were installed. If they are the type with preformed compressible rubber gasket seals or were installed with caulk only, cutting one or more out is no problem. If they are the type that is framed in with aluminum channel between the blocks, then more difficult without breaking blocks.

If you can find vents that almost exactly fit the size of a block, then probably $100-150 would do it (plus the cost of the vents at $30-60 each). If it requires carefully cutting through the blocks themselves to install the vents, then maybe up to twice that.

I have two stupid questions, though -

1) if you like the light from the glass blocks, why mask part of it out with a rather unsightly vent - why not just put a seperate vent through the wall like you would do if you had actual windows in the basement ? Do it yourself, or have it done for probably half the installed cost of retrofitted glass block vents.

2) why hire someone to do it. If you are at all home handy, UNLESS your blocks are prefabbed in metal frame between each block, it should be easy to do yourself - google "glass block vents" and you will find lots of articles and videos on doing it.
