Cerro Gordo Insulation FAQs
My Cerro Gordo bungalow has rooms up in the roof. Why are they hard to keep comfortable?
Because those rooms are built into the slope of the roof, with short knee walls along their sides. The 1998 county survey describes a bungalow near the town with a front gable and dormer windows in its attic story. It found bungalows of that era scattered all over the county. ENERGY STAR warns that the open floor framing under a knee wall can still leak with insulation stuffed into it. So we block and seal those joist spaces, then insulate the side attics along with the main ceiling.
Is anything in Cerro Gordo on the National Register?
No. Nothing here appears among the state's National Register listings. The 1998 survey did place the 1926 school on its proposed study list, meaning it looked eligible, which is a step short of listing. It also recommended a fuller survey of the town. A study list entry places no rules on a private house, so historic rules do not come into attic work here.
Does attic insulation in Cerro Gordo need a permit?
Cerro Gordo Town Hall can say whether Columbus County Building Inspections, the town itself or another office handles permits in Cerro Gordo; ask before work starts.
