What happens the first winter after we leave.

The thermal camera at the end of the job was worth every penny alone. Watching those red patches go green was the most satisfying thing I've seen in 20 years of owning this house.

My realtor told me I'd lost a sale because of the thermal scan. Two days after Blown finished, the reinspection passed clean. Sold for full asking price eleven days later.

I can actually work in my barn in January now. The propane heater runs maybe twice a day instead of continuously. I should have done this the first winter I moved here.
