Garage moisture problems, contractor's bogus solution, or is it?
Just had a ,000 garage built last summer. It is heated and we keep it at 50 degrees. outside temperature 15-25 degree. Humidity running 70-90% 24/7 and as winter sets in, doors are freezing, huge ice dams on windows, man door swells and freezes shut, nothing stays dry in the garage. The slab is not the problem, we tested that, not much moisture there. Inspector feels as though the roof was not properly ventalated causing traped moisture inside the garage.
Contracter come out with plumber and states the problem is they did not install a frsh air vent when they installed modine garage heater. I call BS as modine is designed for garage and circulates fresh air in already. I then tell him, I cracked the window, but humidity still 75% plus. Not to mention now I get an 8 inch hole cut in my garage. Pure BS, the heater will run all the time. Any tips on what could be causing this moisture?
no, it vents outside, via an exhaust 6 inch pipe.
