Commercial Sign Repair in Toronto & GTA

Is your sign dark, flickering, partially illuminated or damaged? Planet Signs provides troubleshooting, repair and maintenance services to help get your commercial sign working properly again.

Don't Let a Broken Sign Hurt Your Business Visibility

A damaged or poorly illuminated sign can make your business harder to notice and leave the wrong impression after dark.

Whether one letter has stopped working or the entire sign has a lighting issue, we can inspect the problem and determine the appropriate repair.

One or More Letters Are Out

Isolated dark modules inside individual reverse or face-lit channel letters caused by bad LED daisy-chains or cut secondary wires.

Sign Is Flickering

Rapid strobing usually signals a failing primary transformer, degraded constant-current power supply, or moisture intrusion in terminal blocks.

Sign Looks Dim

Gradual lumen degradation from aged LED modules, degraded acrylic diffusers, or undervoltage issues from remote driver enclosures.

Sign Doesn't Turn On

Complete system blackout caused by tripped breakers, burnt photocells, blown fuses, severed exterior conduits, or dead primary power supply units.

Damaged Sign Face

Cracked polycarbonates, sun-bleached vinyl overlays, blown-out acrylic retainers, or wind-damaged flexible sign faces that require custom re-routing.

Uneven Lighting

Spotty hot-spots and shadowy letter patches stemming from mismatched Kelvin temperatures, failed lens diffusers, or misspaced back-illumination runs.

Does Your Sign Really Need to Be Replaced?

Not every sign problem requires a completely new sign.

In many cases, the issue may be related to an LED module, power supply, wiring or another replaceable component.

We inspect the existing sign first and help determine whether repair, component replacement or a new sign is the appropriate solution.
