Commercial Surge Protection & Power Quality
Commercial equipment is costly, and a single voltage surge can destroy servers, point-of-sale systems, machinery, and HVAC systems in an instant. Sandiparks Electrical installs commercial building surge protection across London, Ontario, and Southwestern Ontario, with work handled by a licensed electrician and scheduled around your operating hours.

What You Get
What’s Included in Every Sandiparks Surge Protection Job
Effective surge protection for commercial buildings depends on the device,
grounding, and layering. Here’s what’s included in every surge
protection project we complete for a business.
Panel & Grounding Assessment
We inspect your service, panel, and grounding before specifying anything. Surge protection only works with a sound grounding system, so we verify it first and correct it as needed.
Whole-Building Protection
We install a surge protection device at the main panel to protect every circuit at once, taking the first and largest hit before a surge can reach your connected equipment.
Layered Point-of-Use Protection
For sensitive equipment such as servers, POS systems, and control panels, we add a second layer of protection at the equipment level, catching what gets past the panel-level device.
Code-Compliant Installation
Every device is installed to the Ontario Electrical Safety Code by a licensed Master Electrician, correctly rated for your service and integrated cleanly into your existing panel.
Documentation for Your Records
You receive a written record of the devices installed and their ratings. Insurers and auditors increasingly ask for this, and it also tells the next contractor exactly what’s protecting the building.
Businesses comparing commercial surge protection solutions should ask what’s included before comparing prices. Every project we complete covers the full scope above as standard, with pricing clearly outlined in your written quote.

The real cost of a surge is rarely the surge itself; it’s what it takes down. A spike that kills a POS system, a server, or an HVAC control board costs you the cost of replacement plus the hours or days you’re offline. That downtime is why commercial power surge protection is one of the highest-return electrical investments a business can make.
Grounding is the part most installers skip, yet it’s what makes surge protection work. A device on a poor grounding system has nowhere to safely divert a surge, so commercial whole-building surge protection is only as good as the earth behind it. We verify and correct grounding first.
Layering separates real protection from a checkbox. A panel-level device handles large surges from lightning and grid switching, while sensitive electronics require a second layer at the equipment level. Proper commercial surge protection solutions integrate both.
Most damaging surges don’t come from lightning at all. They’re generated inside the building by compressors, motors, and HVAC systems cycling on and off, which is why surge protection for commercial buildings is worthwhile even in areas where storms are rare.
Our Process
What to Expect from Start to Finish
Here’s how a Sandiparks surge protection project runs, from the first
walkthrough to documented handover.
Tell us what you’re protecting
Call, email, or book online. Tell us about your equipment, any past surge damage, and your operating hours. Knowing what’s at risk helps determine the level and layering of protection we recommend.
Site assessment and written quote
We visit, inspect your panel and grounding, and provide a detailed written quote. For commercial building surge protection, this includes verifying that the grounding can properly support the device before any installation.
Installation completed and tested
We install the panel-level device and any point-of-use protection cleanly and to code, then test the installation and grounding. Every device in our reliable surge protection for commercial properties is verified before we consider the job done.
Documentation and follow-up
We hand over the device ratings and records and show you the status indicators. Ryan personally follows up to confirm that everything is protecting the building as intended.
Serving London, Ontario & Surrounding Communities
Based in Mount Brydges, we provide surge protection for commercial buildings across Southwestern Ontario, including London, Strathroy, St. Thomas, Komoka, Dorchester, and Middlesex County.
We protect restaurants, retail units, offices, warehouses, and multi-tenant buildings, delivering reliable surge protection these operations rely on to safeguard costly equipment.
Business owners choose our commercial whole-building surge protection because we verify grounding, layer protection, and document the work, so your equipment is genuinely protected rather than just fitted with a device.

TESTIMONIALS
What Our Clients Say
FAQs
Is surge protection required in commercial buildings?
While not required for all existing commercial buildings in Ontario, the current code does require surge protection for many new installations and specific applications. It is also becoming a requirement for insurers and equipment warranties to maintain coverage. Sandiparks assesses your building and advises where commercial building surge protection is required, recommended, or worth adding for equipment safety.
Why is commercial surge protection important?
Commercial surge protection is crucial because a voltage spike can destroy expensive equipment and cause costly downtime while equipment is replaced. Servers, POS terminals, HVAC controls, and machinery are vulnerable to spikes from lightning, grid switching, and internal equipment. Sandiparks provides commercial power surge protection to safeguard this equipment at the panel and at the point of use.
What does whole-building surge protection actually protect?
Whole-building surge protection is installed at the main panel and simultaneously protects all circuits in the building during a large voltage spike. It safeguards equipment such as HVAC, refrigeration, lighting, and other hardwired systems. Sandiparks pairs this with point-of-use protection for sensitive electronics as part of complete commercial surge protection solutions.
Does surge protection stop power from lightning strikes?
Surge protection safely diverts excess voltage from nearby lightning strikes or grid events to ground, protecting your equipment from surges. It will not prevent a direct lightning strike to the building, which requires a separate lightning protection system. Sandiparks installs commercial whole-building surge protection to guard against the voltage surges that cause most equipment damage.
How much does commercial surge protection cost to install?
The cost will vary based on the size of your service, the device’s rating, whether grounding corrections are required, and the number of point-of-use devices your equipment requires. It is one of the most cost-effective protections available, compared with the cost of replacing servers, HVAC systems, or POS equipment.
How long does a commercial surge protector last?
A good commercial surge protector will last for several years, and most will have indicators to let you know when it is time to replace it. Devices wear out over time and absorb surges, so periodic checks are important. Sandiparks shows you how to monitor yours and provides reliable surge protection for commercial properties using quality devices built to last.
