How do I check if my home has poor insulation?

Start by checking your energy bills. If they're unusually high compared to similar homes, poor insulation is often the cause. Walk through your home and feel for drafts near windows, doors, electrical outlets, and where walls meet the floor or ceiling. On a cold day, touch your interior walls and ceilings. If they feel cold or damp, insulation is likely inadequate. You can also look in your attic to see if insulation is thin, uneven, or missing entirely. Most attics should have at least 10 to 14 inches of insulation. Hiring an energy auditor to perform a blower door test is the most thorough option, as it precisely identifies air leaks and weak spots throughout the entire house.
