Severn Insulation FAQs
Can a concrete block house on White Street in Severn have its attic insulated?
Yes. The county's 2010 survey describes the White Street bungalows and foursquares as concrete block cast to look like rough stone. Local tradition holds that one man in town made the blocks on a machine bought from Sears. The block is in the walls. Overhead, the attic is judged like any other one: how deep the insulation is, where air leaks up from the rooms below, and whether the soffit vents are clear.
Is my house in Severn listed as historic anywhere?
No, by the state's own records. Severn does not appear among the National Register properties kept by the State Historic Preservation Office, and that office's 2023 county list of commission staff skips Northampton entirely. The 2010 county survey did describe several buildings here, among them the brick bank of about 1916 and the block houses on White Street. That write-up is research, not protection, and it puts no conditions on attic work.
Does attic insulation in Severn need a permit?
Severn Town Hall can say whether Northampton County Building Inspections, the town itself or another office handles permits in Severn; ask before work starts.
