mold removal company

[Marina Wong]

Has anyone used Green Home Solutions? Please share your experience. I have a property that has mold 33 ft from the floor (indoor gym) So the look of the end product is important. I wonder if anyone has any experience as what the end result will look like. They have 1 year warranty  and that's what I like about it but I am uncertain as what it might look like because they do not have before / after pictures to share with me (can find some online but not enough to extrapolate for my particular situation) Thank you.

@Marina Wong, given the distance between the bents (the metal framing system), I'm wondering if the roof was constructed using SIPS or SIPS-type panels (a rigid insulated panels with a drywall face on the underside and a plywood/OSB face on the other); do you know?  If so, the ridge may very well be the culprit... either because it is sealed so tightly (not uncommon with SIPS panels) that all the vapor collects at the ridge area with no place to go.  SIPS may have very low permeability rates and so the vapor cannot pass through them and there doesn't appear to be any provisions along the ridge to ventilate (do the sidewalls have mechanical ventilation near the peak?).  Naturally, users of a gymnasium can produce high volumes of vapor (which may manifest as condensation) exacerbating the condition.  

Another option is simply the ridge cap flashing - it may be allowing water from the exterior to enter.

I'd encourage you to have the roof substrate checked too... either condition may be affecting that which is not readily visible.
