Bolton Insulation FAQs
If my Bolton house goes back to the lumber company years, what about the chimney?
It gets its own treatment before any insulation goes near it. A masonry chimney that passes up through the ceiling leaves a gap at the attic floor. We close that gap with light aluminum sheet and a heat-rated caulk. Then a sheet-metal shield goes around the chimney so the insulation cannot touch the brick. ENERGY STAR notes codes generally want 2 inches of open space between masonry and insulation. Little is written about the town's early houses, so we go by what your chimney and ceiling show.
Has anyone surveyed the old houses in Bolton?
Not in detail. The state's 1998 survey of Columbus County looked mainly at the countryside, and it named the town among those that needed a survey of their own. It did record the frame Bolton United Methodist Church and, outside town, a rare Italianate house with a high hipped roof. The town has no National Register listing either, so no listing limits what you can do in your attic.
Does attic insulation in Bolton need a permit?
Bolton Town Hall can say whether Columbus County Building Inspections, the town itself or another office handles permits in Bolton; ask before work starts.
