• Waterproofing, sump or dehumidification needs.
• Electrical panel capacity and lighting plan.

A warm basement depends on the layer behind the drywall. We use continuous foam on the foundation walls in Essex, seal and insulate the rim joist, and fire-block the framing where the code requires it.

That assembly keeps condensation off the framing and makes the room feel like the rest of the house, not like a cellar with carpet.
