Licensed electrical work for Nepean homes.
Cornerstone Electrical works across Nepean and the western Ottawa neighbourhoods on panel upgrades, EV charger installations, basement finishes, lighting, and renovation wiring. From mid-century bungalows in Crestview to newer homes in Centrepointe and the Barrhaven edge, every job is licensed, ESA-permitted, and finished cleanly.
Electrical service built for Nepean's mix of older bungalows and newer suburban homes
Nepean is a mix of established neighbourhoods — Crestview, Parkwood Hills, Centrepointe, Tanglewood — where many homes are 40+ years old and running on 100A panels with outdated circuits. Common jobs here are 100A-to-200A panel upgrades, aluminum wiring remediation, and adding dedicated circuits for EV chargers, hot tubs, and kitchen renos. We work within the City of Ottawa electrical inspection system and handle ESA permits for every job, so nothing falls through the cracks.

The installation was done professionally, everything was neat and well organized, and the entire process was smooth from start to finish. The electrician was incredibly friendly, knowledgeable, and took the time to answer all of my questions. It’s clear they take pride in their work. I highly recommend Cornerstone Electrical to anyone looking for a reliable EV charger installation. Five stars all the way!”

Common questions from Nepean homeowners
Do I need a panel upgrade before installing an EV charger in my Nepean home?
Not always — it depends on your current panel size and load. Many Nepean bungalows still have 100A service, which may or may not handle a Level 2 charger depending on existing loads. We do a load calculation first and give you an honest answer before quoting the install.
How long does a 100A to 200A panel upgrade usually take in Nepean?
Most residential panel upgrades in Nepean are a one-day job: Hydro Ottawa disconnect, new panel and service installed, ESA inspection, and reconnect. If the mast or meter base needs replacement, budget extra time. We coordinate the Hydro Ottawa shutdown for you.
Do you handle aluminum wiring remediation?
Yes. Many Nepean homes from the 1960s and 70s have aluminum branch wiring. We can pigtail outlets and switches with approved connectors to make the system safer, or plan a full rewire during a larger renovation. ESA permit and inspection included.
