Question DetailsAsked on 1/19/2016

Positive air pressure to rid winter attic condensation/frost!

My home: Entire ridge vented with cobra roll. Entire eve's have sofit & rafter baffle venting. Gable end vents are blocked. I also bought into a "professional" air sealing & insulation company! I STILL HAVE MOISTURE! Only out of pure frustration did I place a small fan in one gable vent, blowing into my attic? Positive air pressure has dropped my moisture levels. According to "Fine Homebuilding" and many others, the smart arrows (warm heat) will flow passively up to the ridge? I think the passive air flow thing looks good on paper but it's not working with my home. There are 2 more things I haven't done yet: #1 Block off my soft vents near my windows to rule out warm air being reintroduced via sofit vents? #2 Install another ridge vent to rule out proper air evacuation? GAF Cobra Snow Country vent may be an option? MY PROFESSIONAL INSTALLER HAS BEEN AVOIDING MY REQUEST FOR A BLOWER DOOR TEST (X2). All he says is block off my gable vents? Really looking for help on this, please!
