DIY vs. Call a Pro
Attic batt or blown-in insulation is the most accessible DIY insulation project. Rent a blower from a hardware store for loose-fill cellulose. Wear proper PPE (mask, goggles, long sleeves). Don't compress batts — insulation works by trapping air.
Call a professional when:
Hire a professional for spray foam insulation (requires specialized equipment), wall cavity insulation (requires injection holes), or if asbestos abatement is needed in older homes.
