Assurances, promises, and words are like vapor... if a person decides to do nothing later on, there is no way to force any partner to physically perform.

@Holly Scott why do you think a vapor barrier is needed?

(vapor barrier and foam insulation)* Ridge vent is totally clogged with dust, dirt or something that is preventing flow* There is a heat cord on the roof below where the furnace is located so I am sure the roof is hot in the winter and melts the snow which causes ice damn in the section.* vents and returns are in ceiling..so won't the heat come down and go right back up the return?

The contractors that I know do not have experience with basements as they seem to require special considerations like vapor barriers, foundation grading, etc.

You do want to lay a vapor barrier down- 6-10 mil thick polyethylene.

@Luke LaczakIt sounds like a vapor barrier or sound deadener.

it has organic vapor relief and will help masking the odor a little.  1) open the blinds if any and let as much sunlight in a possible.2) open all windows, let it vent for a few hours before the cleanup.  

We could reseal the edges with rubber scraps to act as a vapor barrier.  

2nd post - You guys gave a LOT of good feedback on the insulation / vapor barrier post - Thanks a LOT.

I have the underlay going in along with the vapor barrier everywhere except the stairs as both floors of the condo I am remodeling is mostly concrete and I want to "protect" the warranty.
