Calcium Buildup on Spa Spillovers & Pool Walls

Why It Matters and Why We Recommend Prompt Attention

At ACME, our goal is to maintain every property’s appearance, function, and guest experience to the highest standards. Calcium buildup on spa spillovers and pool walls is one of the most common and visible maintenance issues in desert climates. While it may seem purely cosmetic at first, allowing it to go unaddressed can lead to costly repairs, poor guest impressions, and long-term damage to your investment.


1. What Causes Calcium Buildup

  • Hard Water: Our desert water has a high mineral content. When water evaporates, it leaves behind calcium and other minerals that cling to tile and stone surfaces.

  • Heated Spas & Spillovers: Heated water evaporates faster, accelerating mineral deposits. Spillover areas see constant movement and evaporation, which concentrates buildup.

  • Chemical Imbalance: Improper pH, alkalinity, or calcium hardness levels in pool water can cause scaling and white mineral streaks to appear quickly.


2. The Impact on Your Vacation Rental

Aesthetic Impact:
Calcium scaling creates white, chalky lines or crust that make even a clean pool appear neglected. Photos taken by guests or inspectors can highlight this as a sign of poor upkeep.

Guest Experience:
Guests expect pristine pool and spa areas. Visible buildup can result in lower satisfaction scores, poor reviews, or negative feedback about “dirty” water or “stained” tile.

Maintenance & Equipment Damage:
Unchecked buildup can:

  • Erode or etch glass tile and stone surfaces
  • Damage grout and cause premature tile failure
  • Clogged Filters & Pipes: Deposits can reduce water flow, strain pumps, and shorten the life of system components.
  • Require aggressive acid washing or tile replacement if left untreated


3. ACME’s Recommendation

We recommend owners remove calcium buildup as needed by contracting a professional service, depending on severity and usage. During annual inspections, our team will note if buildup is visible and recommend service.
