Pools and spas add recreational value to your home, but they're also complex systems that demand thorough inspection before purchase or during routine property checkups. A specialized pool and spa inspection can uncover costly problems—from structural damage to equipment failure—that standard home inspections often miss. If you're buying a home with a pool or spa, or maintaining one you already own, knowing what inspectors should check can save you thousands in repairs.
Why Pool and Spa Inspections Matter
Most standard home inspections glance at pools and spas without diving into specifics. A dedicated pool or spa inspection examines the plumbing, circulation systems, electrical wiring, structural integrity, and safety features in detail. This is critical because pools and spas operate year-round in many climates, and problems can escalate quickly—a cracked shell can lead to foundation damage, faulty wiring poses electrocution risks, and inefficient circulation systems breed algae and bacteria.
When you're purchasing a home with a pool, a specialized inspection provides leverage in negotiations if defects are discovered. Sellers often price homes with pools higher, assuming buyers won't budget for hidden repairs.
What Inspectors Check During a Pool Inspection
A professional pool inspector examines both above-ground and in-ground systems systematically:
- Structural integrity: Cracks in the shell, deck subsidence, loose tiles, and signs of water loss
- Circulation and filtration: Pump performance, filter condition, pressure readings, and pipe leaks
- Chemical systems: Water quality, pH balance, chlorine levels, and salt chlorinator function (if applicable)
- Electrical components: Bonding and grounding, breaker functionality, light operations, and GFCI outlets
- Safety features: Drain covers (anti-entrapment compliance), fencing, gates, and alarm systems
- Equipment age and condition: Heater type and efficiency, automation systems, and remaining lifespan estimates
Inspectors typically spend 2–3 hours on a comprehensive pool inspection and provide a detailed report with photos, cost estimates for repairs, and maintenance recommendations.
Spa-Specific Inspection Points
Spas demand attention to different areas than swimming pools:
- Shell and cabinet: Fiberglass cracks, deteriorating cabinet seals, water stains indicating leaks
- Jet systems: Functioning jets, pressure consistency, and airflow quality
- Heater capacity: Whether the heater can reach and maintain target temperatures (typically 100–104°F)
- Filtration cycles: Cartridge condition, filter bypass, and cleaning frequency requirements
- Plumbing connections: No kinks, cracks, or disconnections in lines running to jets and valves
- Control panel: Display function, button responsiveness, and digital thermometer accuracy
Portable spas are easier to inspect than built-in models because inspectors can access all sides. Built-in spas may require additional excavation assessment to check for ground settling.
Cost and Timeline for Inspections
A standalone pool inspection typically costs $300–$600, depending on pool size and complexity. Spa inspections run $150–$400. Many inspectors offer combined pool-and-spa inspections for $450–$800. If you're buying a home, budget for this specialized inspection separate from your general home inspection—it's worth the investment before closing.
Most inspectors can schedule appointments within 3–7 days. If you're purchasing, request the inspection as soon as your offer is accepted to allow time for contractor estimates if repairs are needed.
Red Flags to Watch For
During the inspection report review, prioritize these concerns:
- Cracks larger than 1/8 inch in the shell or deck
- Pump that runs continuously or won't prime
- Water loss exceeding 1/4 inch per day (indicates a leak)
- Corroded or deteriorated electrical conduit
- Heater age over 15 years without recent service records
- Missing or damaged drain covers (legal liability)
Finding a Qualified Inspector
Not all home inspectors are trained in pool systems. Look for inspectors certified by organizations like the Association of Pool & Spa Professionals (APSP) or the National Swimming Pool Foundation (NSPF). Ask for references and examples of past pool inspection reports.

Frequently Asked Questions
Q: Can I skip a pool inspection if the pool looks clean and clear? Visual clarity doesn't indicate structural soundness or equipment reliability. A pool can appear pristine while hiding circulation problems, electrical hazards, or pending shell failure. Inspections catch hidden issues that affect safety and resale value.
Q: How often should I have my pool inspected after purchase? Annual inspections are recommended, ideally in spring before heavy use or in fall before winterization. These preventive checks catch deterioration early and extend equipment lifespan.
Q: What's the difference between a pool inspection and pool maintenance? Inspections diagnose problems and assess condition; maintenance involves cleaning, chemical balancing, and routine upkeep. You need both, but inspections should happen before major purchasing decisions.
