You may even want to create a swimming pool spreadsheet to compare one pool estimate to other pool estimates. Pay special attention to the types of materials that the contractor will use to construct the pool; project extras such as water to fill the pool, special features, energy efficient pumps, going green, salt systems, patio/decking; warranties on the swimming pool and equipment; project timelines and the types of pool equipment that the pool contractor will use such as pool filter, the pool pump, number of skimmers, returns, turnover rates, number of lights, steps, swimming pool vacuums, etc. Many companies will entice a buyer with low prices and then increase the price dramatically with extras that may be included in another pool company’s base pricing- make sure you compare the bids equally across the board.
Most projects involve subcontractors, employees, equipment suppliers and others that are paid as a project proceeds or as needs arise. A delay in payment may slow down or even stop aspects of your project mid-stream. A slowed or stalled swimming pool project almost always increases the overall cost of the pool project. If you anticipate issues with the payment schedule, speak up early as the contractor may be able to move the project schedule around to protect you and your pool project.While you should not wrongly hold back payments, don’t make your final payment until your swimming pool is completed.Your previous payments during the project should ensure that construction and equipment, decking or fencing by the contract has been completed. Your final payment is your strongest insurance that your pool project will be completed as agreed. If you must make your last payment early, make sure that you get in writing a list of what still needs to be completed and the timeline for the remaining tasks.
The nature of references is that almost every reference will be positive. Do not depend on references to be a critical analysis of the pool contractor. The reference should give you an idea of how the contractor works on the project and how specific projects and issues were handled.
Swimming pool construction is handled by specialized swimming pool contractors who are experienced in ground conditions and climate of the region.

Ask the references about how and why they picked this contractor and about their experience work with the contractor. Find out if any issues came up during the project and how they handled the issues. Ask if they would have done anything differently in hindsight. If you cannot see the finished swimming pool project first hand, ask the pool contractor for pictures.
Your swimming pool. Most contractors expect to receive money at stages during the project. inground swimming pool Contractors that request you to pay for the entire project in cash up front are operating illegally.
