Seal Gaps and Add Insulation
Nothing makes a home more uncomfortable during the winter than a nagging, chilly draft. Consider a home energy audit that includes a review of your home’s caulking and weather stripping. An energy auditor also will likely look inside your attic. If the insulation is at or below the level of the joists, you might be able to keep your home warmer by adding more insulation. A depth of 10-14 inches is generally considered optimal, and you can supplement with a variety of types of insulation to achieve that depth.
