After blowing insulation into the attic, we spent the rest of the morning putting up R8 outside insulation on the laundry area to prepare for siding.
Fresh snappy air does one good, but when we entered the house for lunch, we both stopped dead at the kitchen door and just looked at each other with our noses wrinkled up. There was no mistaking the smell...sewage. Of course the sewage pipe is not in the basement, it's in the part of the house with only a crawl space. Son just loved his trip under the house. He did find the problem. A cracked old cast iron sewer pipe. Looks like tomorrow will be another fun day.
