A good LED system can run for many years with very little attention, but "very little" is not zero. Texas yards grow fast, sprinklers leave mineral deposits, storms knock fixtures out of alignment and timers drift with the seasons. Regular landscape lighting maintenance keeps every fixture bright, balanced and aimed where the designer intended.
Below is a simple routine: a monthly five-minute check, a season-by-season checklist built around the Texas calendar, and clear signs that it is time to call a pro.
Monthly quick checks
Once a month, take a slow walk around the yard after dark. It takes about five minutes and catches small problems before they become bigger ones.
- Every fixture turns on at the scheduled time
- No fixtures are dark, dim, flickering or noticeably different in color
- Nothing has been knocked over by mowers, pets, kids or contractors
- Plants are not blocking path lights or covering uplights
- No glare is shining into windows, the street or neighbors' yards
- The transformer cover is closed and the outlet's in-use cover is latched
Seasonal landscape lighting maintenance for Texas
Texas seasons do not line up neatly with the rest of the country. Spring brings storms and explosive growth, summer brings heat and heavy irrigation, fall brings the time change and leaf drop, and winter brings the occasional hard freeze. Here is what to focus on in each.
| Season | Main Texas factors | Maintenance focus |
|---|---|---|
| Spring (Mar to May) | DST starts, rapid plant growth, hail and severe storms | Reset timers after the March time change. Trim new growth around fixtures. Inspect for storm and hail damage. Re-aim fixtures disturbed by spring landscaping. |
| Summer (Jun to Aug) | Extreme heat, heavy sprinkler use, hurricane season begins | Clean mineral deposits from lenses. Adjust sprinkler heads away from fixtures. Check that the transformer is not overheating. Review storm prep. |
| Fall (Sep to Nov) | DST ends, leaf drop, longer nights, peak hurricane season | Reset timers after the November time change. Clear leaves from well lights. Check wire runs exposed by fall bed work. Review holiday plans so extra loads do not overload the transformer. |
| Winter (Dec to Feb) | Occasional hard freezes, dormant plants, longest run times | Inspect after any freeze or ice. Use dormancy to see fixtures clearly and re-aim. Check connections and fixture stakes. Plan any upgrades or additions. |
Cleaning lenses: hard water and mineral deposits
In much of Texas, municipal and well water is hard. Every time a sprinkler hits a fixture, it leaves a thin film of calcium and other minerals. Over months, that film turns into a cloudy crust that can noticeably dim the light and scatter it into glare.
Turn it off
Switch off the system and give fixtures a few minutes to cool.
Wipe the surface
Use a soft cloth to remove dust, cobwebs and loose dirt from lenses and housings.
Dissolve the deposits
Apply a mild solution of white vinegar and water, let it sit briefly, then wipe gently. Avoid abrasive pads that can scratch glass or remove finishes.
Rinse and dry
Rinse with clean water and dry the lens so new spots do not form.
Fix the cause
Adjust or replace sprinkler heads that spray fixtures directly. This step does more than any cleaning product.
Tip: In-ground well lights collect leaves, mulch and grass clippings. Clear the top lens and the area around the fixture so heat can escape and water can drain.
Trimming plants around fixtures
Texas landscapes grow fast. A path light that was perfectly placed in October can be buried by spring. Trim shrubs and groundcovers so path lights stand clear, and keep foliage from pressing against uplight lenses. Remember that the goal is to light the plants, not hide the fixtures inside them. For trees, keep the canopy you are uplighting reasonably open so light reaches into the branches instead of stopping at the lowest leaves.
Re-aiming fixtures
Mowers, edgers, pets and storms all nudge fixtures out of position. A light that has tilted a few degrees can go from grazing a stone column to shining straight into a bedroom window. After dark, check each uplight and wall washer against the surface it is meant to light, and look for any glare from the street or your porch. Plants also change shape as they grow, so a tree that needed two uplights at installation may need them repositioned a few years later. Our landscape lighting techniques guide explains how each fixture type should be aimed.
Checking connections and wiring
Connections are the most common source of problems in an aging system. Moisture that reaches copper causes corrosion, which raises resistance and dims or kills fixtures downstream.
- Look for exposed wire where mulch has washed away or beds were reworked
- Watch for fixtures that flicker when you tap the stake, a sign of a loose connection
- Note any section of a run that went dark all at once, which often means a cut or failed splice
- Check the transformer terminals for discoloration, corrosion or loose screws
- Make sure wire entering the transformer has a drip loop so water cannot run inside
Transformer timers after the DST change
Daylight saving time starts on the second Sunday in March and ends on the first Sunday in November. Mechanical timers and basic digital timers do not know that, so your lights may come on an hour early or late, and sunset itself shifts across the year. In much of Texas, sunset moves from around 5:30 PM in early winter to roughly 8:30 PM in late June.
The simplest fix is to replace an old timer with an astronomical timer, a photocell or a smart controller that adjusts automatically. If you keep a manual timer, add timer checks to your March and November routine. Our sunset timer planner shows sunset times by month so you can set a schedule that works year-round, and our smart lighting controls remove the chore entirely.
Transformer care
The transformer rarely needs attention, but a quick look twice a year is worth it. Open the cover with the power off and check for wasp nests, ant colonies and debris, all common in Texas. Make sure vents are clear and nothing is stacked against the enclosure. If the unit feels very hot during a summer evening or hums louder than it used to, it may be overloaded or failing. Adding fixtures over the years without checking capacity is a common cause, which our guide to transformer sizing explains.
Keep a simple maintenance log
A short log makes landscape lighting maintenance faster every year. Note the date of each seasonal check, any fixtures you re-aimed or replaced, lamp types and wattages, and the transformer tap used for each run. Take a few nighttime photos of the yard when everything is aimed just right. Next season, compare against those photos and you will spot drift immediately. The same records are useful after a storm or when you decide to expand the system.
When to call a pro
Most maintenance is easy DIY work. These signs point to something bigger:
Whole runs go dark
Several fixtures failing together usually means a cut wire, failed splice or problem at the transformer.
GFCI keeps tripping
Repeated trips point to moisture or a fault. Leave it off and have it checked. Outlet work needs a licensed electrician.
Uneven brightness
Dim fixtures at the end of runs often need re-tapping, heavier wire or a hub layout.
Our landscape lighting repair service handles diagnostics, wiring repairs, fixture replacement and full system tune-ups. If storms are your main concern, see our guide to protecting landscape lighting from Texas storms. We serve homeowners from Fort Worth to Round Rock and across the state.
If your system needs more than a cleaning, or you want a professional tune-up before the season changes, we are happy to take a look.
