After purchasing an old house in Maine I blew insulation in the walls. But, as a first time home owner, I filled the soffit while I was blowing insulation down the second floor walls from the attic and now the air flow is restricted and there is condensation from rising moisture in the attic.
I know the cause of the moisture is the lack of ventilation because fresh air cannot flow up to the attic from the soffit, but what can I do to restore the air flow?
Would it be worth it to push plastic tubing or pvc down through the blown-in insulation and cut a hole in the soffit for one end and vent the other into the attic to restore air flow? Or are there other remedies out there that I could try?
