What it is
Retrofitting existing homes with blown-in fiberglass or cellulose, mainly in attics, plus sealing air leaks, and sometimes batts in crawl spaces and walls. You work from a truck or van with a blowing machine.
Your first three steps
- Check your state and county contractor licensing rules and which jobs need a license
- Get a quote for general liability insurance, then price a used blower machine and a work truck or van
- Meet local HVAC companies, realtors and home energy auditors to ask for referrals, and look up local utility rebate programs
Who pays
Homeowners, landlords and property managers, often prompted by high energy bills, drafty rooms or utility rebate programs.
How it makes money
Fixed quote per job, usually based on square footage and the R-value you install, plus extra for air sealing and removing old insulation.
Skills that help
- Comfortable with physical work in tight, hot attics
- Measuring and quoting accurately
- Explaining the benefits clearly to homeowners
Watch out for
- State or local contractor license requirements, which vary a lot, so check your state licensing board
- General liability insurance, and workers' compensation once you hire anyone
- Older attics may contain vermiculite or asbestos, so know when to stop work and call a specialist
- EPA lead-safe rules may apply if you disturb paint in homes built before 1978, so check requirements
- Heat, dust and confined spaces: use proper respirators, eye protection and safe walking boards
