These job titles are essentially interchange and all fall under the C-2 license for insulation and acoustical contractors.
Duties of an Insulation Contractor
Insulation contractors engage in a wide variety of duties including:
Getting the C-2 license will require that you have knowledge of all aspects of the insulation and acoustical trade.
A C-2 Insulation & Acoustical contractor legally is not allowed to bid on a project that falls outside of the spectrum of general insulation, acoustical construction, maintenance or repair work.
C-2 License Requirements
To qualify for an exam date for the C-2 license you must meet the following requirements:
- 18 Years of Age

- Social Security OR ITIN Number
- Cannot Currently be on Probation or Parole
You must also have:

What is Journeyman Level Experience?
Journeyman level experience means that you have worked unsupervised full time for a construction company, a contractor with the C-2 License, or union.
The CSLB will want to see four full-time years experience over the last ten years. The years do not need to be consecutive, but they do need to be four years in total.
Signature Of A Qualifying Individual
A qualifying individual is someone other than yourself who can confirm your experience.
This person can be either a:
- Licensed General Contractor
- Licensed Insulation and Acoustical Contractor (C-2 License)
- Fellow or Former Employee (within the last 10 years)
- Foreman or Supervisor
- Business Associate
- Fellow Journeyman
Whoever you choose must include their information and a brief description of your experience.
The main areas of expertise an Insulation Contractor needs to have experience in are:
- Installing Grid Ceiling Systems
- Erecting Scaffolds and Ladders
- Installing Sound Control Systems, pipes and duct work
- Sealing Buildings to stop air infiltration
- Insulating attics
- Weather stripping
- Foil Reinforced Insulation
- Applied Polyurethane Insulation
- Insulated Pipes
- Rolled Insulation Batts
- Sprayed Foam
Filling out the C-2 License Application
When you are filling out your application to the CSLB, you must remember that the description your qualifying individual writes for you has to go into detail about your specific skill set.
Instead of just saying: "John has insulated homes…"
The CSLB will want to see: "John has installed grid ceiling systems, sealed buildings to stop air infiltration, installed weather stripping, soundproofed recording studios etc.
Insulation contractors that hold the C-2 license typically work directly with clients.
However if they are working in a traditional construction setting they would function as a subcontractor under a company or individual who holds the General B license.
- Music and Entertainment Industry Clients
- Residential and Commercial Setting
- Optimizing Control Systems
- Knowledge of Acoustics
- Creating Sonically Balanced Rooms
- Insulation and Acoustical Services
A General Contractor is in charge of the job from start to finish and must make sure that the insulation and acoustical portion of the project is completed to the specific requests of the client.
Proving your work experience for the C-2 License
You must be prepared to submit documentation supporting the experience you claim to have.
The Contractors State License Board gives you many ways to prove your experience including:
- Tax Returns
- Check Stubs
- Material Order Invoices or Receipts
The CSLB receives thousands of applications per month.
So there is a good chance they won’t document your experience.
However, if you are one of the applicants that get reviewed you will need to be ready to submit something.
The CSLB does not accept pictures of projects.
Application Processing, Fees, and Criminal History
The time it takes to get your application processed and assigned a test date fluctuates throughout the year.
Typically you can expect:
- 6-8 Week Application Processing Time
- 3-4 Week wait for an Exam date
I have seen some situations where applicants got their test date sooner and some where they got their test date much later.
The most common reasons your application would get held up are:
- Time of year (processing time slows down during the holidays)
- Criminal History
- Proving Experience
- Mistakes on your application
- State Application Fee - $330
Can you get a contractors license with a Felony In California?
Having a criminal record in no way stops you from getting a C-2 License.
The key is to be honest on the application, even if the felony or misdemeanor happened years ago and even if it was expunged.
BE 100% HONEST ON THE APPLICATION, because they will see everything anyway when you do fingerprinting.
The CSLB handles criminal records on a case by case basis.
Remember, their responsibility is to protect the public. In my experience, they primarily concerned with criminal charges associated with:
In the state of California, you are required to divulge any criminal charges when applying for any state license even if they have been expunged.
You will need to be prepared to submit anything they ask for regarding your criminal history.
