Future-proof your Grimsby home by upgrading your electrical service panel.
If your home’s electrical system is outdated, overloaded, or no longer meets insurance or safety requirements, Stack Electric provides professional electrical panel upgrades in Grimsby, Ontario.
We upgrade aging 60-amp and 100-amp services to modern 200-amp systems that safely handle today’s electrical demands — including EV chargers, air conditioning systems, hot tubs, renovations, and high-efficiency appliances.
All work is completed by licensed electricians and inspected in accordance with ESA requirements.
When Do You Need a Panel Upgrade?
Many homes in Grimsby were built when electrical demand was far lower than it is today. If you’re experiencing any of the following, it may be time to upgrade:
-
Frequent breaker trips
-
Flickering lights
-
Fuse panels or outdated breaker panels
-
Insurance requiring an upgrade
-
Renovations or additions increasing load
-
Installing an EV charger or hot tub
An outdated panel is more than an inconvenience — it can be a safety risk.
