Hard Ground or Rock – During swimming pool and spa excavation and trenching, if hard ground or rock is encountered that cannot be removed by, or in a reasonable time frame, the tractor on site and a larger machine or blasting is required there may be an extra charge. This is the standard in the industry nationwide.
Heater – Natural gas or electric apparatus that heats water as it passes through it. A swimming pool or spa heater has no tank.
HOA approval – Home owners association approval may be required prior to constructing a swimming pool. Though they vary widely, most HOAs require only the initial swimming pool design for approval. This can take up to 30 days so application HOA approval should be submitted as early as possible. There may also be a fee. The fee is generally not the responsibility of the swimming pool contractor.
