What is a Licensed Plumber?

Plumbers are professional trades-persons who deal with the installation and repair of pipes and fittings. In particular, pipes and fittings which carry water or gas, as well as for heating and sanitation systems. Plumbers carry out their work in homes, offices, and factories.

Licensing is a very important aspect of becoming a plumber. This is because once a plumber is licensed they are certified as having the requisite knowledge, expertise, and experience to carry out their work according to recognized plumbing standards.

They also have insurance which is intended to help their customers in the event that the plumbing work was faulty.

Plumbers that are not licensed may be penalized for carrying out plumbing work without a license.

How to Become a “Licensed Contractor” in California

Construction is a science which requires precision. Lack of precision can lead to faulty construction resulting in loss of life and property. This is why the construction industry in California is regulated by the state of which licensing is just one part.

Safeguarding California residents’ lives and their right to enjoy property, the state requires specific contractors to be licensed. Licensing confirm the individual’s knowledge in the area and authenticates that their work is of a certain standard. This ensures safe and quality construction work.

What do I need to become a Contractor

From the outset, all prospective contractors in California must know that they may be required to get a construction license if they wish to pursue this trade. California makes it mandatory for all contractors to be licensed especially if they intend to bid for a project which is valued at $500 or more. This includes both the project’s material and labor costs. Therefore, one of the biggest incentives in getting licensed in California is the ability to bid for high value, big construction projects. Unlicensed contractors can only bid for small construction projects.

The state of California repeatedly reminds its residents to ONLY hire state-licensed contractors. Smart consumers will ask to see a contractor’s “pocket license”. It is therefore in the contractor’s own interest to get licensed both to avoid state penalties, including jail term and more importantly, build customer confidence, leading to a long-term business relationship.


Prospective contractors must contact the Contractors State License Board (CSLB) for licensing. While in-depth information is available on CSLB’s website, the following may help in getting started:

  • Pass a criminal background check
  • Post a license bond
  • Pass exams (business and trade and license law)
  • Verify four years of journey-level experience in the trade

Getting licensed may be a time consuming process and therefore it is advised that all prospective contractors start early.

Penalties for Unlicensed Contractors in California

The CSLB was established to protect consumers. The Board ensures high construction standards through regulation and penalizes those who are found to be in violation of state construction laws.

Unlicensed contractors through faulty construction can put peoples’ lives in danger. In addition, they give a bad name to the whole industry and avoid taxation through engaging in unlawful trade activities. To curb this practice, the CSLB’s team called Statewide Investigative Fraud Team (SWIFT) conducts undercover operations to unearth illegal construction rackets.

The first offence is classified as a misdemeanor, which is punishable with up to 6 months in jail and/or a $5,000 fine. The convicted may be sentenced with an additional administrative fine of $200 to $15,000. After serving the sentence, if the contractor continues with their old ways, they could be slapped with a fine of $5,000 or 20% of the contract price. Furthermore, second offence automatically attracts a jail term of 90-days.

It must be remembered that not all violations of California’s construction laws result in a misdemeanor; some are classified as felony as well. Those who misrepresent themselves as licensed contractors or use another person’s license for the purpose can be convicted of a felony. Felons serve jail time in state prison.

Is California Contractor’s License worth the Effort?

Yes! In addition to the reasons given above, there is one more reason which should stop an unlicensed contractor – unlicensed contractors can be “ripped off”. Unlicensed contractors cannot legally sue for non-payment. Imagine a shady customer finding out their contractor’s licensing status and refusing to pay once the project is completed?

How to Become a Concrete Contractor

How to become a concrete contractor, before you enter the concrete business, bear in mind that the competition is stiff, therefore be ready to work really hard to make it big. Once you are mentally ready for this intensive business, you can initially penetrate the market working on small residential projects and even multi-level commercial jobs. Your first year of operation would be the hardest, but by producing work to the customers’ satisfaction, you can ensure the success of your concrete company.

How to Become a Concrete Contractor in California?

There are certain things you will need to take care of to enter into this business. Have a look:

Education Requirements:

To become a concrete contractor, you will need at least a bachelor’s degree or equivalent in civil engineering or a related field. After that, you will need to obtain a license, which is a requirement in every state.


No matter how learned you are on the topic in terms of theory, you will still need to gather a sufficient amount of experience. The industry you are dealing with is vast, and will require an understanding of a lot of difficult concepts and procedures. For this purpose, you are advised to get firsthand experience, both on the field and in terms of office work. This will allow you to work directly with materials, suppliers, homeowners and contractors.

Target Market:

You’ll need to know your target market. You may want to focus on commercial projects such as offices, schools and public works, or you can go for residential work that would involve pouring walkways and patios in people’s yards, etc. Concrete companies that work on both residential and commercial projects are very few, since the tools, skills and expertise required for both vary a great deal. Decide at the start which sector you want to work in.

Business Plan:

You need to have a business plan in place before anything. You will need to know the direction of your business, your goals, and strategies and so on. Even if you can finance the business on your own, having a proper plan will help you remain focused on the important matters at hand. Within this document, add your target market segments, your company’s mission and philosophy and your projected financial data. You can revise the plan semi-annually to keep it updated.

Purchase/Lease Equipment:

This would be particularly important if you are planning to work in the commercial field. For work in this area, you will need to get your hands on heavy duty mixers, vehicles and other required professional quality tools.

Legal Aspects:

This is one of the first things you should take care of when you plan on starting a business. Get in touch with a lawyer and discuss your options. You can consider forming an LLC or a corporation in order to make sure your personal assets are protected. You will also need to obtain liability, company auto insurance and worker’s compensation insurance.


As soon as you initiate the planning phase of your concrete business, you will need to start looking for trustworthy suppliers. It is common for certified concrete contractors to arrange for a supplier who provides them with pre-mixed concrete. There are a lot of concerns you will need to keep in mind in terms of the supply chain, including scheduling of orders, drying of the concrete, the weather, etc.


To get into the commercial world, you have to start somewhere. You are recommended to start with the Blue Book’s BB Bid System. This is a free book service that lists every contractor in the US according to region. You can get a hand on a copy of this book in any contractor’s office. This helps you list your company for free. Contractors will then begin inviting you to place bids on projects as soon as you are listed. In addition to that, you are advised to meet with local contractors and request your company to be added to their bid list. And as far as the residential work projects go, you should ask any one you know to spread the word about your business and help you grow.

Once you have taken care of all of these matters, you can begin your business activities as a certified concrete contractors.
