Pool Light
Repair
Pool light niches are one of the most overlooked sources of water loss in DFW pools. When the niche or conduit fails, water doesn't stay at the pool — it can travel beyond the shell and into surrounding areas. We identify the failure and repair it before it becomes a larger problem.
The Leak You're Not Looking For
Most pool light leaks go undetected for months. The niche sits below the waterline, the conduit runs behind the shell, and water loss from a failed niche seal looks identical to any other unexplained water loss — which means homeowners often chase the wrong cause before identifying the light as the source. Without testing the niche directly, this type of leak is easy to miss.
Most light leaks aren't visible at the surface — they occur behind the shell through the niche and conduit system.
We test pool light niches directly as part of our leak detection process. If the niche seal has failed, if the conduit is allowing water to migrate, or if the light assembly itself has cracked, we identify it and repair it before any additional damage occurs.
Most pool light leaks we see are at the niche-to-shell seal — the point where the niche body meets the pool shell. This seal deteriorates over time and with temperature cycling, and when it fails, water exits through the conduit path rather than staying in the pool.
With over 20,000 repairs completed across DFW, we've seen how often light niche failures are misdiagnosed — and how to identify them correctly.

The Right Repair Starts With the Right Diagnosis
Pool light failures occur at different points in the niche and conduit system. The location of the failure determines the repair — which is why we test the full system before recommending any scope of work.
Niche Seal Repair
The niche seal is the gasket and sealing material between the light niche body and the pool shell. When this seal fails, water bypasses the niche and enters the conduit path. We reseal the niche-to-shell connection, restoring a watertight barrier between the pool and conduit system.
Conduit Leak Repair
When water enters the conduit — the pipe that runs from the light niche to the junction box — it can travel significant distances before causing visible damage, which can otherwise continue unnoticed. We identify where the conduit is allowing water intrusion and seal it at the source, preventing further migration into the surrounding structure.
Light Assembly Replacement
When the light assembly itself — the fixture, lens, or housing — has cracked or failed, water enters through the fixture rather than through the niche seal. We replace the light assembly with the correct fitting for the niche and pool type, restoring a proper watertight seal at the fixture level.
How It Works
Pool light leaks require a specific diagnostic approach — standard leak tests don't isolate the niche.
Niche & Conduit Diagnosis
We test the light niche directly using dye testing under controlled conditions. We assess the niche seal, conduit entry point, and light assembly for any sign of water movement. This isolates the light system from other potential leak sources. We confirm this through physical inspection — not assumptions.

Pool Light Repair — FAQ
The most reliable way to confirm a pool light leak is a dye test around the niche. If dye is drawn toward the niche seal or conduit entry, that confirms active water movement at that point. A pool that loses water at the same rate regardless of whether the equipment is running or off — and where other leak sources have been ruled out — is often traced back to a light niche failure. We confirm this through targeted testing — not by eliminating other possibilities.
Yes, in some cases. The conduit that runs from the light niche typically terminates at a junction box, which may be located in a wall cavity or equipment enclosure near the pool. If the conduit is carrying water, that water follows gravity and can cause damage well beyond the pool itself. This is why conduit leaks should be addressed promptly.
The water level typically needs to be lowered below the light niche for most repairs. Full niche replacement may require draining further depending on the niche position. We'll tell you exactly what water level is needed before any work begins.
Yes — in most cases. If the niche body and seal are intact and only the fixture has failed, we replace the assembly without disturbing the niche. If the niche itself is cracked or the seal has deteriorated, we address that as part of the same repair.
Electrical work on pool light circuits requires a licensed electrician. We coordinate with licensed electrical contractors when the scope of the repair involves wiring or junction box work. Our repair scope covers the niche, seal, conduit, and assembly — we'll be clear about what requires a separate electrical contractor.
