What You Get
What’s Included in Every Sandiparks Sign Job
Proper illuminated sign installation on the electrical side is about more than
running a wire to a sign. Here’s what’s included in every signage
project we complete for a business.
Dedicated Sign Circuit
We install a dedicated circuit sized to your sign’s power draw, run from the panel with the correct breaker, so your signage never shares a circuit with interior equipment or trips a shared breaker.
Code-Required Disconnect Switch
Ontario code requires an accessible disconnect for electric signs. We install it within sight of the sign or in a lockable enclosure so the sign can be safely shut off for service or in an emergency.
Sign & Storefront Wiring
From panel to sign, we take care of the entire wiring job, including conduit, weatherproofing, and connections, whether the sign is on your storefront, wall, or freestanding structure.
Permit & Inspection Coordination
We file the ESA permit, complete the work in accordance with the Ontario Electrical Safety Code, and coordinate the inspection so the electrical side of your signage is documented and compliant.
Coordination With Your Sign Company
We provide the permitted electrical connection they’re not licensed to complete, working to their schedule so the project finishes cleanly. Businesses comparing options for commercial sign electrical work should ask what’s included before comparing prices.
Installing new signage?
From storefront signs to freestanding pylons, our storefront sign wiring and connection work is permitted and inspection-ready. Call for an honest, upfront quote.

Sign wiring is a specialty, and if you don’t know what you are doing, projects go wrong. Since 2011, Ryan has been working on commercial sign electrical projects, and it is evident in the details that keep a sign running reliably for years.
The disconnect requirement catches many businesses out. Ontario code requires an accessible disconnecting means for every electric sign, positioned within sight or capable of being locked out, so that a service technician or first responder can safely shut off the power. Skipping it fails inspection, which is why every sign disconnect switch installation we complete is placed to meet code from the start.
Sign type shapes the overall approach. Channel letter sign wiring uses low-voltage connections to individually lit letters and requires clean, concealed routing, while a pylon sign usually requires a long underground conduit run and a weatherproofed base.
Our Process
What to Expect from Start to Finish
Here’s how a Sandiparks signage project runs, from the
first call to inspection-ready handover.
Tell us about the sign
Call, email, or book online. Tell us the sign type, its power requirements, where it’s going, and which sign company is fabricating it. That determines the circuit, the run, and the disconnect.
Site assessment and written quote
We visit, assess the distance from your panel, the mounting location, and the power draw, then provide a detailed written quote. For a pylon sign electrical project, this includes the conduit run and base connection.
Permit, circuit, disconnect, and wiring
We file the ESA permit, install the dedicated circuit and disconnect, and complete the wiring to code. Every commercial sign wiring job is weatherproofed and tested before we schedule the inspection.
Inspection and handover
We coordinate the ESA inspection and hand over the documentation. Ryan personally follows up to confirm that the sign is powered, compliant, and performing as intended.

TESTIMONIALS
What Our Clients Say
FAQs
Do I need a permit to install electrical wiring for a commercial sign in Ontario?
Yes. In Ontario, electrical wiring for an illuminated commercial sign requires an ESA permit and inspection, separate from any municipal sign or building permit. Sandiparks manages the full ESA permit and inspection process for every commercial sign electrical project in London and Southwestern Ontario.
Who is responsible for the electrical hookup of a business sign, the sign company or an electrician?
The sign company creates and installs the sign, and a licensed electrician installs the approved electrical connection, circuit, and disconnect. In Ontario, sign fabricators typically do not hold the licence to make the electrical connection; therefore, collaboration between the two trades is required. Sandiparks coordinates directly with sign companies to complete the commercial sign wiring side of these projects.
What is a sign disconnect switch and is it required?
A sign disconnect switch is a switch mounted outside the sign and shuts off all power to the sign for safe service or emergency shutoff. The Electrical Safety Code in Ontario mandates that a disconnect be accessible within sight of the sign or be lockable. Every sign disconnect switch installation Sandiparks completes is placed to meet code.
Does an illuminated sign need its own dedicated electrical circuit?
Yes, an illuminated commercial sign should be on its own dedicated circuit rather than sharing power with other loads. A dedicated circuit prevents breakers shared with interior equipment from tripping and ensures reliable operation. Sandiparks installs a properly sized dedicated circuit with every illuminated sign installation in the London area.
How much does it cost to wire a commercial sign?
The cost depends on the distance from the panel, the sign’s power requirements, the disconnect and circuit required, and the ESA permit. A storefront sign near the panel costs less than a pylon sign that requires a long underground conduit run. Sandiparks provides upfront written quotes for channel letter sign wiring, pylon signs, and storefront signage across London and Southwestern Ontario.
How do I find a licensed commercial sign electrician near me in London, Ontario?
Look for a licensed Master Electrician with ECRA registration, full insurance, and experience coordinating with sign companies on permitted installations. Confirm they handle the ESA permit, dedicated circuit, and disconnect as a complete package, not just part of the job. Sandiparks is a licensed, ECRA-registered commercial sign electrician serving London and Southwestern Ontario, handling sign work from permit to inspection.
