How to hire a insulation contractor

  1. Ask for an energy audit. Blower door tests identify air leaks.
  2. Confirm target R-value. Northern climates typically aim for R-49 to R-60 in attics.
  3. Ask about air sealing. Insulation works best after air sealing.
  4. Check ventilation. Baffles keep soffit vents open.
  5. Ask about rebates. Utilities often offer insulation rebates.

Red flags to watch for

  • No air sealing included
  • Blocks soffit vents
  • Covers knob-and-tube wiring without evaluation
  • Unrealistic energy savings claims

Licensing in Missouri
