If you want to install a pool in your yard, you will need to hire pool builders to do the job. In some states, these contractors must be licensed or at least state-certified. You can hire a licensed or certified Orange Countys pool contractor, and can get good services and designs for the construction of your dream pool.
The first thing you will want to know is how long it has been since they built the pool. You have to ask how many pools they have installed. Some builders have been in the industry for years but know very little about building swimming pools. Also, knowing how long they have been in the business is important because you want to make sure it's an established business.
Ask the builder if you might have some recommendations. You have to get some new and old customers so you can compare the jobs. They will hesitate if they tell you they don't have the link or can't provide you with this information. Once you have a list of recommendations, you can call two or three random people and ask if they are happy with their homework. The most important thing you want to know is whether they will hire this contractor again.
Ask if the builders are aware of all the precautions they need to take. Make sure that when you hire certain contractors, you are informed about what they are doing. You don't want to know six months later that something wasn't done right.
