Step 1: Gather Essential Tools

• Flashlight: Inspect dark spaces like attics, basements, and crawlspaces.
  
  
• Ladder: Safely access attic spaces and higher areas.
  
  
• Measuring Tape: Measure insulation depth, gaps, and calculate square footage.
  
  
• Incense Sticks: Detect drafts by observing smoke movement.
  
  
• Infrared Thermometer or Thermal Camera: Identify cold spots indicating poor insulation.
  
  
• Protective Gear (Dust Mask & Gloves): Protect from insulation fibers and dust.
  
  

Step 2: Inspect the Attic

• Ideal insulation depth: 16-20 inches (fiberglass), 13-15 inches (cellulose).
  
  
• Check for insulation gaps, uneven distribution, moisture damage, and rodent presence.
  
  
• Identify dirty fiberglass insulation as it indicates air leakage.
  
  
• Ensure proper ventilation by checking for baffles along soffits to allow airflow into the attic.
  
  
• Verify bath fans exhaust properly outside through roof or gable walls. Use toilet paper to test fan suction.
  
  

Step 3: Check Your Walls

• Use a lit incense stick to detect drafts along interior walls. Smoke movement indicates leaks.
  
  
• Turn off HVAC, fans, and exhausts. Ensure all windows and doors are closed during testing.
  
  

Step 4: Inspect Basement and Crawlspaces

• Use a flashlight to thoroughly inspect rim joist insulation.
  
  
• Look for cobwebs, as spiders commonly indicate areas of insect entry and drafts.
  
  
• Examine foundation walls and surroundings for drafts, moisture, and damage.
  
  

Step 5: Examine Windows and Doors

• Confirm windows and doors seal tightly without gaps.
  
  
• Inspect windows for moisture buildup, a sign of poor insulation or inadequate sealing.
  
  

Step 6: Evaluate HVAC and Ductwork

• Ensure HVAC vents have flow adjusters and that they are open.
  
  
• Confirm ductwork is securely connected, especially in attic spaces.
  
  
• Check ducts for proper insulation to reduce heat loss.
  
  
• Regularly replace HVAC filters to maintain efficiency.
  
  

Step 7: Document Your Findings

• Clearly record problem areas, prioritizing based on severity and potential energy savings.
  
  
• Develop an action plan for insulation and weatherization improvements.
