The cost of a swimming pool varies tremendously but is largely a factor of the choices you make – the size and depth of the pool, the decking, the interior finish, lighting, and landscaping. And there are some factors beyond our control such as construction equipment access issues, and the availability and cost of any special materials we need to build your pool. Most pools average $34,000.00. The good news is that you can control most of the costs and whatever you spend, it will increase the value of your home.
