Ask for references from any contractor you consider hiring for a job like this. Most contractors will be able to provide you with a list of references or tell you about jobs they've done. If these jobs were done on public property, you can go inspect the quality of the contractor's work for yourself. If not, you will be able to contact the people that the contractor has worked for in the past.

Ensure you hire a contractor that has a high level of insurance. There are a number of things that can go wrong during the construction of a concrete pool. These problems can become major issues in some cases. When you get a contractor that has a reasonable level of insurance, you will be protecting yourself from any financial problems down the road.

Getting an estimate from your contractor is essential. Your contractor should be able to give you a reasonable estimate in terms of materials, time, and overall cost. If your contractor is unable to do this for you, then it is likely that he or she is not very experienced with concrete pools.
