Landscape Lighting Maintenance Schedule — What to Do and When

Low-voltage LED landscape lighting is low-maintenance by design. But "low-maintenance" is not the same as "no maintenance." A landscape lighting system that is not periodically serviced will gradually drift from its original design — fixtures settle and lose their angle, transformer settings drift, and seasonal overgrowth obscures lighting positions. Annual maintenance keeps the system performing as designed.

*Spring tune-up (April–May):* The priority maintenance window for Chester County landscape lighting. Winter freeze-thaw cycling shifts fixture angles and stake depth. Emerging foliage from spring planting can obstruct fixture positions that were clear in winter. JHL's spring service includes: fixture realignment to original design angles, lens cleaning (dust and debris accumulate on fixture lenses over winter), transformer inspection and timer reset for the longer day length, and identification of any fixtures that have failed or been damaged.

*Timer adjustment (twice per year):* Sunset time shifts approximately 90 minutes between the summer solstice and the winter solstice in Chester County. Most low-voltage transformers require manual timer adjustment twice per year — after daylight saving time changes — to keep the system turning on at dusk and off at the desired time. Smart transformers with photocell and app control adjust automatically.

*Annual inspection items:* Wire connections — check exposed wire runs at bed edges for physical damage from lawn equipment. Fixture stakes — check for uplift from frost heave. Transformer — inspect for moisture infiltration, verify all circuits are loaded correctly, test photocell.

*Failure patterns:* LED failures in a properly installed system are uncommon but do occur. The most common failure modes: wire connection moisture infiltration (failure at outdoor splices), transformer circuit overload (too many fixtures on one tap), and physical damage from lawn equipment or landscape work.
