Wateree did do a lot what I believed good for my house and I am thankful for what stands as good. Since they finished, a season later I noticed mold growth on crown molding to ceiling . All the years here I never had mold growth from humidity . The ventilation they claim met government standards and all the sealing I thought would have impacted humidity in the house. They believe they have done all that they could. Since I was left alone to determine cause of this sudden mold , I learned from ac heating service that the unit that was installed through this weatherizing by wateree praise God for , it is not the correct heating strips for this house size. It is 5kw and need be 8-10 for this house. I am mostly disappointed in the lack of follow through by wateree to back their weatherization. Instead of my thermostat being on 68 and that being too warm at night with old unit it now is drafty and needing to be on 70-72 my hoise no longer efficient in energy cost . My kitchen is brand new walls and crown molding that were installed and now I am needing to remove crown molding , reinstall and repaint . I have calls into other contractors to help determine what steps I can do to return my house to balance after wateree weatherization led house to be otherwise As great as the work done it has not shown to improve efficiency and cost for me.
