While the primary elements of a swimming pool construction project are consistent from one plan to another, there are a great variety of options that can affect the costs and there are numerous features that can be included. In addition, there are a number of swimming pool contractors in the St. Louis area and not every contractor utilizes the same estimating process.
To help you better understand why there are variations in the prices for in ground swimming pools, you should consider that the price is determined not just by the size of the pool, but also by the quality of materials and construction as well as the complexity of the design and whether the contractor includes all aspects of construction in its price estimate.
Many pool contractors are inexperienced with certain site situations and therefore bring in their bids lower to win the job and then add the numerous “cost overruns” after construction starts. While every pool builder faces some uncertainty with the costs to prepare the hole for the pool (due to rock, sinkholes, etc) many also do not factor in essential elements like deck caulking, systems integration, and safety features.
