Common Problems We Fix
Most outdoor lighting failures in Houston trace back to a handful of causes. Here is what we see most and what usually causes it.
A Whole Section Went Dark
One run of lights stops working while the rest stay on — usually a cut or corroded wire splice, a failed connector, or a tripped transformer terminal.
Most common cause: damaged buried wireTransformer Not Powering On
Nothing works at all. The transformer may have failed, tripped its internal breaker, lost its timer program, or be overloaded past its wattage capacity.
Most common cause: overload or ageLights Flicker or Cut In and Out
Flickering almost always means a loose connection, moisture inside a socket, or voltage drop from wire runs that are too long or too thin for the load.
Most common cause: moisture in socketsFixtures Corroded or Faded
Cheap aluminum and plastic fixtures pit, chalk, and crack in Houston's humidity. Lenses fog and the light output drops dramatically.
Most common cause: non-brass fixturesLandscaping Has Outgrown the Lights
Shrubs swallow fixtures and tree canopies grow past the beam. The system still works but no longer lights what it was aimed at.
Most common cause: growth over timeTimer or Photocell Wrong
Lights come on at odd hours, stay on all day, or never turn on — typically a failed photocell, a lost timer program, or a dead backup battery.
Most common cause: failed photocellHow a Repair Visit Works
1. Full System Diagnosis
We test the transformer output, check voltage at fixtures along each run, and trace the fault to its actual source rather than guessing. You get a clear explanation of what failed and why.
2. Written Repair Options
We tell you what needs fixing now, what can wait, and what is worth upgrading instead of repairing. Pricing is presented upfront before any work starts — no surprise invoices.
3. Repair & Replace
Most repairs are completed the same visit: re-splicing wire in waterproof connectors, swapping failed fixtures, replacing lamps, or installing a correctly sized transformer.
4. Re-Aim & Rebalance
We re-aim every fixture, trim back growth blocking beams, and rebalance the load so the whole system looks intentional again — not just the part that broke.
5. Night Walkthrough
We confirm the results after dark with you, adjust anything you want changed, and set the timer or photocell to your schedule before we leave.
Repairs, Upgrades & Additions
Service calls start at $250. Larger repairs and upgrades are quoted after diagnosis.
Repair, Upgrade, or Replace?
Not every failing system needs to be torn out. A well-installed low-voltage system with solid-brass fixtures is worth repairing almost indefinitely — brass survives Houston's humidity, and individual components are replaceable. If your fixtures are still solid and only the wiring or transformer has failed, repair is almost always the better value.
The calculation changes with cheap fixtures. Aluminum and composite housings pit and crack within a few Gulf Coast summers, lenses cloud permanently, and sockets corrode. Once a majority of fixtures are failing, replacing them one at a time costs more over a couple of years than upgrading the system properly.
The Halogen Problem
Many Houston homes still run older halogen landscape lighting. Halogen lamps burn out constantly, draw roughly five to six times the power of an equivalent LED, and generate enough heat to degrade sockets and lenses over time. Converting to LED usually pays for itself through bulb replacements and power savings alone — and the light quality is dramatically better.
We Service Any Installer's Work
You do not need to have been our customer. We regularly take over systems installed by companies that have gone out of business, moved away, or simply stopped answering the phone. We will diagnose whatever is in the ground and tell you honestly what it needs.

Outdoor Lighting Repair FAQs
How much does outdoor lighting repair cost in Houston?
Repair service calls start at $250, which covers a full system diagnosis and most straightforward fixes such as wire re-splicing or lamp replacement.
Larger work like transformer replacement or an LED conversion is quoted after diagnosis, always with upfront pricing before we begin.
Will you repair a system another company installed?
Yes, and we do it often. Many of our repair clients had their system installed by a company that has since closed or stopped servicing the area.
We work on all major low-voltage brands and will diagnose whatever is already in the ground.
Why did just one section of my landscape lights stop working?
When one run goes dark but the rest stays lit, the fault is almost always in the wire feeding that run — a cut from digging or edging, a corroded splice, or a connector that has let water in.
We trace the run with a voltage meter to find the break rather than digging up the whole yard.
Why do my outdoor lights flicker?
Flickering usually points to a loose or corroded connection, moisture that has worked its way into a socket, or voltage drop caused by wire runs that are too long or too thin for the number of fixtures on them.
It is worth addressing quickly, because the same moisture and heat that cause flickering will eventually kill the fixture.
How long does a landscape lighting transformer last?
A quality transformer typically lasts ten to fifteen years. Cheaper units, or ones running near their maximum wattage, fail much sooner.
If your transformer is failing, we size the replacement with headroom so you can add fixtures later without overloading it.
Should I convert my halogen landscape lighting to LED?
In almost every case, yes. LED lamps use roughly a fifth to a sixth of the power of halogen, last dramatically longer, and run cool enough to stop cooking your sockets and lenses.
The savings on replacement bulbs and electricity typically cover the conversion cost over time, and the light quality is noticeably cleaner.
Can you add more lights to my existing system?
Usually yes. First we check whether your transformer has spare wattage capacity and whether the existing wire gauge can carry the additional load.
If there is headroom, we extend the runs to your new areas. If not, we will tell you what needs upgrading first rather than overloading the system.
My lights turn on at the wrong time. Can that be fixed?
Yes, and it is usually a quick fix. The cause is normally a failed photocell, a timer that lost its program after a power outage, or a dead backup battery inside the transformer.
We replace the failed component and set the schedule to the hours you actually want.
How often should landscape lighting be maintained?
Once a year is right for most Houston properties. An annual visit covers re-aiming fixtures that have shifted, clearing growth that blocks beams, cleaning lenses dulled by humidity and pollen, and checking connections before they fail.
Regular maintenance is far cheaper than emergency repairs and keeps the design looking the way it was intended.
Do you offer maintenance plans?
Yes. We offer optional maintenance plans that include scheduled visits for lamp replacement, re-aiming, lens cleaning, and connection checks.
Plan clients also get priority scheduling when something does go wrong. Ask about it during your service visit.
