Short Answer
Check the attic, basement, and exterior walls for insulation type, depth, and condition. Look for gaps, compression, moisture damage, and pest infestation. The recommended R-value for attic insulation in New Jersey is R-49 to R-60. Check for proper ventilation in the attic. Poor insulation leads to higher energy bills and can cause ice dams in winter. A home energy audit can provide a comprehensive evaluation of insulation and energy efficiency.
Good insulation is essential for comfort and energy efficiency, especially in New Jersey's climate. Start by checking the attic. Measure the depth of the insulation. In New Jersey, the recommended R-value for attic insulation is R-49 to R-60, which is about 16 to 20 inches of fiberglass or cellulose insulation. Look for gaps, compression, and areas where insulation is missing. Check for signs of moisture, mold, or pest infestation in the insulation. Check the attic ventilation. Proper ventilation prevents moisture buildup and ice dams. Look for soffit vents, ridge vents, and gable vents. Check the basement or crawlspace for insulation. In New Jersey, basement walls should be insulated to at least R-15. Check for air leaks around windows, doors, and where pipes and wires enter the home. A home energy audit, typically costing $300 to $500, includes a blower door test and thermal imaging to identify air leaks and insulation gaps. Many New Jersey utilities offer free or discounted energy audits. The audit report will recommend improvements and estimate energy savings.

Good insulation is one of the most cost-effective investments you can make in a home. I have seen buyers save hundreds of dollars per year on energy bills after improving insulation. If you are looking at an older home, the insulation is likely inadequate by modern standards. A home energy audit will tell you exactly what you need. Some utility companies in New Jersey offer rebates for insulation upgrades. Let us include an energy audit in your inspection if energy efficiency is a priority for you.
