    1. Get three (3) proposals with estimates in writing.
    2. Ask for information to verify qualifications, contractor license, insurance, etc.
    3. Ask the contractor to provide a list of references and call to verify their work.

The Federal Trade Commission (FTC) regulates home insulation through its Home Insulation Rule 460 with information available online for consumers (see the website). The rule requires that:

  • Consumers hiring contractors must receive fact sheets about installed insulation.
  • Customers must receive a contract or receipt for the insulation installed.
  • The receipt must show the coverage area, thickness, R-value and number of bags of fiber used.
  • The receipt must be dated and signed by the installer.
  • New home sellers must list the type, thickness, and R-value of each type of insulation installed in each part of the house on every sales contract.
