I just recently bought a 7 year old home, with a partially finished basement. The floor is all tongue and groove 4*8 sheets nailed down tightly...Now here is the kicker, under the plywood is wooden trusses(?) on the dirt floor. And NO VAPOR BARRIER!
Is there a way to blow in (sort of like insulation) some kind of barrier? We don't really want to rip up all 1586 sq ft boards, to lay plastic, but that is our last resort.
Does anyone have any ideas on what we can do? I live in Northern British Columbia, Canada, so it is something we need to take care of, ASAP.
Any input is appreciated.
