Blower door test – Des Moines, Iowa
I’m trying to help a friend in Des Moines, Iowa obtain a blower door test & follow it up with directed air sealing. How does/should one go about finding a contractor to perform a blower door test? Is there a city/state database of contractors able to perform a blower door test? For renovation projects, how do most contractors who perform blower door tests receive new business? Lastly, what should one look for when choosing a contractor to perform a blower door test and/or air sealing?
