Top Mistakes Pool Builders Make—and How to Avoid Them

This article explores the common missteps that pool builders often encounter, offering practical advice on how to avoid these pitfalls to ensure a successful pool construction project.

Skipping Proper Site Evaluation

Many builders rush into projects without adequately assessing the site. This can lead to issues down the road, such as drainage problems, unstable soil, or even structural shifts after the pool is installed.

A thorough site evaluation involves analyzing the terrain, vegetation, soil quality, and existing drainage systems. Builders should invest time in understanding these aspects before proceeding.

The slope of the yard, the proximity of nearby trees, and the soil’s ability to retain or drain water can all dramatically impact the success and longevity of the pool.

For instance, building on expansive clay or loose sandy soil without mitigation steps can cause the pool to settle unevenly over time. Poor drainage planning can result in flooding around the pool deck or unwanted erosion. These kinds of problems are not just expensive—they’re avoidable.

It’s also worth consulting with a geotechnical engineer when in doubt. The cost of a professional soil report is minor compared to the expense of having to tear out and rebuild a structurally compromised pool. Failure to properly evaluate the site can lead to costly retrofits and unhappy customers, making this a critical mistake to avoid in pool construction.

Underestimating Construction Costs

Cost overruns can plague a pool building project if not properly estimated. Understanding the full scope of expenses is crucial to avoid financial strain—not just for the builder, but also for the homeowner who may feel misled or frustrated by unexpected changes.

Many builders fail to account for unexpected expenses, such as increases in labor costs, delays due to weather, or the need for additional materials when the actual site conditions don’t match the plans. Excavation surprises—like hitting rock or discovering utility lines—can also derail a well-planned budget.

To prevent financial pitfalls, builders should create a detailed budget that includes a contingency plan for unexpected costs throughout the construction phase. A 10–15% buffer is a good rule of thumb, giving breathing room for surprises without compromising the project.

Beyond that, transparency is key. Communicating clearly with the client about what’s included, what’s optional, and what could change helps manage expectations. Using itemized estimates rather than lump sums allows homeowners to see where the money is going and gives them confidence in your professionalism.

Upfront planning and financial foresight are what separate seasoned pros from amateurs. Builders who take this seriously build more than pools—they build trust.

Ignoring Local Regulations and Permits

Failing to comply with local regulations and obtaining necessary permits can result in project delays or even legal issues that could halt construction. Yet, some builders still attempt to cut corners here, hoping to save time—only to pay for it later.

Understanding the zoning laws, safety codes, and local building codes is essential for every project. This compliance not only ensures legality but also enhances the overall quality of work. Regulations often dictate specifics like pool setbacks, fencing, electrical grounding, anti-entrapment drain covers, and more—things that aren’t just bureaucratic red tape, but important for safety and long-term viability.

For example, many municipalities require that all pool equipment be placed a certain distance from property lines or dwellings. If ignored, builders could be forced to relocate plumbing, pumps, or heaters—racking up significant extra costs.

Permits also come with inspections at different stages of the build, which serve as a quality checkpoint to ensure that the project meets minimum standards. Trying to work without them can result in stop-work orders, fines, and damage to your professional reputation.

Staying informed and playing by the rules protects everyone involved—and it keeps projects moving forward without costly detours.

Overlooking Maintenance Requirements

Many builders do not communicate the maintenance needs of the pool to the owners, leading to dissatisfaction and potential damage in the long run. A beautiful pool on day one means little if the homeowner doesn’t know how to keep it that way.

It’s important for pool builders to outline the necessary maintenance procedures, seasonal care, and chemical balance required for optimal functioning of the pool. This includes educating the owner about filter cleaning, pump schedules, water testing, winterization, and when to call a professional for service.

Even pools marketed as “low maintenance” still require routine attention to prevent algae growth, equipment wear, or imbalanced water chemistry. Without this knowledge, clients may neglect their investment and blame the builder when issues arise.

Providing clients with a comprehensive maintenance guide can lead to increased satisfaction and longevity of the pool investment, minimizing the likelihood of repairs down the line. Going one step further—like offering a starter kit or connecting them with a reliable local pool service—adds real value and positions the builder as a long-term partner, not just a contractor.

In the end, well-informed clients are happy clients—and happy clients are more likely to refer future business.
