Pools and spas are among the most expensive systems on a residential property and among the most frequently underinspected. A standard home inspection covers the pool or spa in a limited way, noting visible conditions and whether mechanical components operate. A dedicated pool and spa inspection goes much further and commands a fee that reflects the value it delivers. Here is what the service involves, what it takes to offer it professionally, and why it is worth adding to your menu.
Why Pool and Spa Inspections Are Underserved
Most residential home inspectors do not go deep on pools and spas. The components are specialized, the knowledge base required is distinct from standard home inspection, and many inspectors default to recommending a pool specialist in their standard report rather than performing a thorough evaluation themselves. That creates a gap.
Buyers purchasing homes with pools often have no clear picture of the pool’s actual condition at closing. They know if the pump runs and the water looks clean. They typically do not know whether the plumbing is leaking, whether the electrical bonding is intact, whether the shell has structural cracks, or whether the equipment is at end of life. Those unknowns represent potential costs of $5,000 to $50,000 or more. A thorough pool inspection answers those questions.
What a Pool and Spa Inspection Covers
A professional pool and spa inspection evaluates the following systems and components.
The shell and interior finish. Inspectors evaluate the plaster, pebble finish, or tile for cracking, delamination, staining, and surface deterioration. Structural cracks that penetrate the shell are a significant finding. Surface cracks in older plaster are common and often cosmetic but still worth documenting.
The deck and coping. Concrete or paver decks are evaluated for cracking, heaving, drainage toward the pool, and trip hazards. Coping stones or tile at the pool edge are checked for integrity and proper drainage.
The pump, motor, and filter. These are operated and evaluated for function, noise, vibration, and condition. Equipment age is documented. A pump at or beyond its expected service life gets flagged for budgeting even if it is currently operational.
The heater, if present. Gas or electric heaters are operated and checked for proper function, signs of corrosion, and code compliance issues.
The electrical systems. This is the most safety-critical part of the pool inspection. Proper bonding of all metal components including the pump motor, ladders, handrails, lights, and any metallic surfaces within the pool area is required by code. Improper or missing bonding creates a risk of electrical shock in the water. GFCI protection on pool-area receptacles and equipment is checked. Pool lighting is evaluated for proper installation and watertight integrity.
The water chemistry and safety features. Basic water chemistry can be tested on-site with a standard test kit. Safety features including proper drain covers compliant with the Virginia Graeme Baker Pool and Spa Safety Act, working safety shutoffs, and proper fencing and gate hardware are evaluated and documented.
Certification and Training Requirements
Oregon and Washington do not require a separate state license specifically for pool and spa inspection as an add-on to a home inspection service. However, professional training is essential before offering this service. The Association of Pool and Spa Professionals (APSP) and the National Swimming Pool Foundation (NSPF) both offer certification programs. The Certified Pool and Spa Inspector designation from APSP provides credibility and structured training in pool systems, electrical bonding, code requirements, and documentation standards.
InterNACHI also offers a pool and spa inspection course that provides a solid foundation for home inspectors adding this service. The course covers the systems above, common defects, and reporting protocols. For an inspector already confident in general home systems, this course combined with hands-on practice is sufficient to start offering pool and spa inspections professionally.
Equipment Needs
Adding pool and spa inspection requires minimal additional equipment beyond what most home inspectors already carry. A basic water chemistry test kit runs $20 to $50 and tests for pH, chlorine, alkalinity, and stabilizer. A non-contact voltage tester is used to verify GFCI protection and electrical component function. A flashlight rated for wet environments is useful for inspecting underwater lights and submerged equipment. Some inspectors add a basic leak dye test kit to assess visible cracks for active leaking.
Revenue Potential
Pool and spa inspection fees in the Portland metro and Southwest Washington market typically run $150 to $300 as an add-on to a standard home inspection. Some inspectors in markets with higher pool density charge standalone pool inspection fees of $200 to $400. The time requirement is 45 to 90 minutes depending on pool complexity and equipment quantity.
Pool density in the Pacific Northwest is lower than markets like Arizona or Florida, so this add-on attaches to a smaller percentage of jobs than radon or sewer scope. But properties with pools are often higher-value homes where the inspection fee itself is higher, and buyers of those properties are particularly motivated to understand what they are buying. Attachment rates on homes with pools can be very high when the service is proactively offered.
The Safety Case for Thorough Pool Inspection
Pools are not just expensive. They are a genuine safety risk when electrical systems are improper. Electrical shock drowning, caused by AC current entering pool water through improperly bonded or grounded equipment, is responsible for deaths and injuries every year. An inspector who identifies missing or inadequate bonding at a pool and documents it clearly has potentially prevented a tragedy. That kind of finding is exactly why thorough specialty inspection matters.
