I ran into a fellow contractor while I was at the bank just now. I inquired about a job Energsmart had bid on for a beautiful new home on the Niagara River. He replied that the owner had chosen to go with fiberglass. I then asked how the homeowner came to his decision. They indicated that the homeowner had heard about how “all the houses getting foamed were having moisture problems.”
I knew immediately that I had to write a blog post when I got back to the office. It really fires me up when people spew out such nonsense just because they heard it from someone else who heard it from someone else. The statement that these houses are having moisture problems just isn’t true.
After tightening a house with foam, it is possible that house could experience an increase in moisture levels if it isn’t managed properly. We’ve had only two complaints out of 1,200+ jobs about moisture levels in homes we’ve insulated. In both cases, the homeowner had moisture buildup on the windows. After asking the owner a handful of questions we found they weren’t ventilating their home properly.
For example, they would take showers and not use the bath fan to evacuate the steam. Other characteristics of homes that could increase moisture levels include not using fans for cooking, ventless gas appliances, and high levels of house plants. Problems caused by these characteristics are very rare and minor. The situation can usually be remedied by using a simple bath fan to carry moisture laden air out of the home and fresh air into the home.
So, in summary, be careful about what you hear on the street. The source of 100% of these comments are from insulation companies that don’t offer foam. If someone tells you any of this nonsense about moisture problems, ask them for a name and number of the person it happened to. I’ll take a bet any day that they won’t be able to supply it. No one at Energsmart has firsthand knowledge of an issue with any foam installer that wasn’t extremely minor and able to be resolved inexpensively. We install this product for a living and if these problems were happening we would most definitely be hearing about it and we’d likely be heading out of business.
