    During your free assessment, we’ll evaluate your home and ensure your coverage meets Alberta’s latest fire and building codes.

  • Yes. Every home should have both smoke and carbon monoxide detection.


    Most modern detectors combine both functions into one convenient, hardwired unit offering complete protection against two of the most common household hazards.

Wiring Repair & Replacement FAQs

  • No. In Calgary, aluminum wiring repair or replacement must be performed by a licensed electrician, and most projects require an official City of Calgary electrical permit.

    Electrical inspectors look for loose connections, oxidized terminals, and improper splices, all of which are common in older aluminum systems.


    Emerald Electric Ltd. provides comprehensive inspections, certified aluminum remediation or copper rewiring, and insurance-approved documentation to ensure your home passes inspection safely.

  • It depends on your insurance provider. Some insurers may offer limited coverage, but most require professional aluminum remediation or full copper replacement before issuing or renewing a policy.

    If your provider has flagged aluminum wiring as a concern, we can assess your home and guide you through your safest and most cost-effective options.

  • In Calgary homes built during the 1960s and 1970s, aluminum wiring was popular because it was lighter and less expensive than copper.
    However, aluminum is softer and more prone to oxidation, leading to loose connections, overheating, and fire hazards.


    Copper wiring is stronger, more durable, and a better electrical conductor, making it the safer, longer-lasting standard for modern homes and renovations.

  • Homes built between 1965 and 1978 are most likely to have aluminum wiring.
    Look for markings such as “AL,” “ALUM,” or “ALUMINUM” on exposed wires or circuit breakers.
    Other warning signs include flickering lights, frequent breaker trips, or warm outlets.


    To confirm, schedule a professional inspection with Emerald Electric — our certified electricians can identify aluminum circuits and recommend safe, code-compliant solutions.

  • Yes! Emerald Electric Ltd. proudly serves Calgary and nearby communities including Airdrie, Cochrane, Okotoks, Chestermere, High River, Strathmore, and more.

Hot Tub Installation FAQs

  • Most hot tubs require a dedicated 240-volt circuit, a GFCI disconnect, and outdoor-rated wiring enclosed in protective conduit. The exact wiring depends on your hot tub’s brand, model, and amperage requirements — typically 50 to 60 amps.


    A licensed electrician ensures proper grounding, weather protection, and safe component placement that meets City of Calgary electrical codes.
    At Emerald Electric Ltd., we perform on-site assessments and make sure your wiring matches manufacturer specifications and local safety standards.

  • In most cases, yes. When your hot tub sits away from your home or main electrical panel, the wiring must be buried underground in protective conduit per City of Calgary regulations.


    We handle the entire process — from trenching and conduit installation to permits and inspections — ensuring your system is safe, compliant, and built to last through Calgary’s weather extremes.
    If trenching is required, we’ll include it in your detailed quote and explain the process upfront — no surprises.
