If you want to build a swimming pool in your garden, you need a builder. However, you can't just hire someone. People for this work must be specially trained in building a pool. If you want to contact pool builders in Orange County, you can get them via https://www.bluefountainpools.net/.
The base pool builder must have a valid license in the category of pool construction. If they specialize in construction and repair, they must also be registered as a pool builder on their license.
If a general builder who specializes in building construction applies for a license as a pool builder, he must be classified as a pool specialist. Or they have other specialized people to do the job. For the entire scope of the project, plumbers, gardeners, and others have to do the work if they give permission.
You have the right to ask the builder to verify his license or registration verification. It must be current and valid before you start work on a project. You can also ask them to show their ID. Make sure the registered name should match the company name.
Whether they specialize in building concrete pools, fiberglass pools, or flooring pools, be sure to ask for references from them. You must take at least two. One must be filled in and the other can be updated. When you call them to find out, ask how the company is doing from start to finish. Also, ask if any subcontractors are involved and what the quality of their work is like.
