The tradesman that hold the C-57 license can engage in a variety of drilling-related work including:

In many cases, drilling contractors that hold the C-57 license often work directly with:

- Private Mineral water Treatment Companies
However, they may also function as a sub to a General Engineering Contractor to continually engage in water drilling work for multiple projects over an extended period of time.
General Engineering Contractors oversee that the well drilling subcontractor has executed their duties with adherence to state and federal regulation.

The Contractors State License Board (CSLB) is the governing body for all contractors in the state of California.
Their responsibility is to protect the consumer public and ensure that anyone charging over $500 for construction services is qualified and registered with the state of California.
The well-drilling contractor license is issued to contractors by the CSLB.
The CSLB administers applications, exams, and maintains a database of all active and inactive contractor license numbers which are public domain.

What is journey-level experience?
Journeyman-level experience means that you have worked unsupervised full-time for a drilling company or a contractor that holds the C-57 license.
- A journeyman can perform all of the duties associated with his or her trade.
The CSLB will want to see four full-time years over the last ten years.
The years do not need to be consecutive, but they do need to be four years in total.

How to fill out the C-57 License application
Your Qualifying Individual will also need to provide a brief but detailed description of your knowledge and skill set.
The way this description is written will be critical to whether or not your application is accepted.
“Bill and his team were excellent, they have done various projects for us” is not be descriptive enough.
The CSLB will want to see:
“Bill has done bailing, swabbing, excavation, and drilling. He has operated a rotary rig, forklift, done job site evaluations and disinfected wells” etc.
The description written by your qualifying individual will need to include the core skills required for a well-drilling contractor.
Work experience for the Contractors' License
You must be prepared to submit documentation supporting the experience you claim to have.
The Contractors State License Board gives you a few ways that you can prove your experience.
- 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 but 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 somewhere 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
Application Costs of the C-57 License
The Current CSLB fees are:
- State Application Fee
- License Activation Fee (after you pass the exam)
- Bond Fee (What is a Construction Bond?)
Can you get a Contractor's License with a Felony in California?
Having a criminal record in no way stops you from getting a C-57 License. I have personally helped guys with all types of criminal records obtain multiple licenses.
The key is, to be honest on the application, even if the felony or misdemeanor happened years ago and even if it was expunged.
See the CSLB's verbiage below:
Just because you have been convicted of a crime does not automatically mean
your application will be denied. CSLB's Criminal Background Unit (CBU) reviews
all criminal convictions to determine if the crime is substantially related to
the duties, qualifications, and/or functions of a contractor. Since no two
conviction records are the same, they are reviewed on a case-by-case basis. The
criteria used by CSLB include whether the crime shows the present or potential
unfitness of an applicant or licensee to perform the functions authorized by
the license in a manner consistent with the public health, safety, or welfare.
In addition, CSLB reviews and considers any evidence of rehabilitation
submitted by the applicant or licensee. Please see the above link to the
California Code of Regulations sections 868 and 869 for more specific
information on the criteria for determining substantial relationship and
Learn more about the Background Check Process here:
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 are primarily concerned with criminal charges associated with:
- Money Laundering
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 the CSLB asks for regarding your criminal history.

Water Well drilling schools in California
If you don’t have the 4 years required journeyman level experience to get a C-57 license for water well drilling, your journey begins here.
Drilling is a global multi-billion dollar sector of construction.
Generally, someone looking to get into this trade would find a union or apprenticeship program.

Blueprint Reading Course
It is critical for drilling contractors to be able to read construction blueprints or at least be able to recognize lines and symbols.
Construction blueprints communicate important information about the area surrounding a structure and how it has been built including materials necessary.
Being comfortable with construction blueprints is an invaluable skill for all tradesmen but is especially important for those looking to get the C-57 license. See our Free Blueprint Reading Course!
Occupational Safety Hazard Association
Statistically, 21% of all work-related fatalities are in construction.
That equals about 1 and 5 worker deaths on average.
In the construction industry, the leading cause of worker deaths is reported as falls, struck by an object, electrocution, and caught-in/between.
The drilling industry can be dangerous, especially if your workers are not properly trained.
For employment with a drilling contractor, it is typically required that you have completed some level of OSHA training.
