    1. The coverage area to be insulated.
    2. The installed R-value (note – this in not the thickness but the actual, final R-value when everything is completed.)
    3. Total cost (is it an hourly rate, fixed price or based on coverage area)
    4. Verification of any rebates available and how to receive these.
    5. The proposed schedule for completing the installation.
    6. Expressed Warranties for the work.
    7. Potential issues the contractor might face during the installation process

    1. The number of years in business
    2. Do they have a contractor’s license (if necessary) to operate in the state.
    3. Are they a member of the Better Business Bureau (Always call the BBB to see if there have been any complaints against the contractor.)
    4. Is the contractor a member of the Insulation Contractors Association of America (ICAA), the National Association of the Remodeling Industry (NARI), the National Home Builders Association (NAHB) or other industry associations.
    5. How many years of experience do the people actually installing the Cellulose insulation have with the contractor.
    6. Does the contractor have insurance to cover any accidents while working on your project?
  3. Ask the contractor to provide a list of references and call them to inquire:
    1. Did the contractor complete the work on schedule.
    2. Did they receive a written estimate and did it include all final costs.
    3. Did the contractor maintain a clean work environment and clean up afterwards.
