If you are thinking of installing a pool in your yard, you will need to hire some pool builders to do the job. Some states require these contractors to have a government license or at least be certified. If your state is one that does not require a license or certification, then you should choose your pool maker carefully.
The first thing you'll want to know is how long it took them to build the pool. You have to ask how many pools they have installed. There are several builders who have been in the industry for years but know very little about building swimming pools. Also, knowing how long you have been in the business is important because you want to make sure they are well established.
Ask the maker if you have some recommendations. You want to get some new customers as well as old customers to be able to compare jobs. You should hesitate if you are told that they do not have a link or cannot provide you with this information. Once you have a list of recommendations, you can randomly call two or three 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 builders know all the safety precautions they need to take. If you decide to hire a particular contractor, make sure they tell you what they do. You don't want to find out six months later that something wasn't done right.
