Whether you’re renovating a kitchen, adding a second storey, or opening up walls that haven’t been touched in decades, electrical renovations hamilton homeowners trust need to be planned around what’s actually behind those walls, not just what’s visible today.
Electrical renovations hamilton homeowners take on range from a single kitchen remodel to a full second-storey addition, and each one comes with its own set of code requirements that go well beyond simply moving an outlet or adding a light. A kitchen renovation alone triggers specific circuit requirements most homeowners have never heard of. An addition means recalculating whether your existing panel can actually support the new square footage. And almost any renovation that opens up older walls tends to reveal wiring decisions made decades ago that now need to be addressed, whether or not that was part of the original plan.
Mercanti Electric is the electrical renovations hamilton homeowners turn to, handling everything from a single-room remodel to a full addition requiring new circuits, panel capacity, and coordination with your general contractor. Joseph Mercanti brings 13 years of electrical experience and full ESA/ECRA licensing (#7017086) to every project, planning the electrical work around your actual renovation, not a generic checklist.
Every renovation and addition is different, and the electrical scope should match the actual project, not a one-size-fits-all package. We assess your specific plans and flag what the code requires before work begins, not partway through.
This is one of the most detail-heavy parts of any kitchen or bathroom renovation, and it’s easy for a homeowner to underestimate how specific the requirements actually are. Under the Ontario Electrical Safety Code, kitchen counter receptacles require dedicated small appliance branch circuits, typically two 20 amp circuits using either split receptacles or T-slot outlets, not standard 15 amp general-use circuits. Spacing matters too, no point along a counter can be more than about 1.8 metres from a receptacle, and any receptacle near the sink needs GFCI protection. Islands and peninsulas that meet a minimum size threshold require their own dedicated receptacle as well.
Bathrooms carry their own version of this, with GFCI-protected receptacles required within a set distance of the sink, and specific circuit requirements for a renovated space. These details are exactly the kind of thing that gets missed when a kitchen or bathroom renovation is planned around cabinetry and finishes first, with electrical treated as an afterthought. We plan counter and fixture layouts alongside your designer or contractor from the start, so receptacle locations and circuit requirements are built into the design, not squeezed in around it.
Adding square footage to your home doesn’t just mean running more circuits, it means your entire electrical service needs to be reassessed for the added demand. A second-storey addition, a rear extension, or a converted garage all add lighting, outlets, and often new appliances or HVAC equipment, and that additional load has to be accounted for against your existing panel’s actual capacity. This is a proper electrical load calculation, not a rough estimate, and it determines whether your current service can absorb the addition or whether a service upgrade needs to happen alongside it.
This is a step that’s easy to skip when an addition is planned primarily around square footage and layout, with electrical capacity assumed to just work itself out. We calculate your home’s total anticipated demand, existing plus added, as part of the planning stage for any addition, so a capacity shortfall is identified before construction starts, not discovered when the addition is finished and breakers start tripping.
A renovation that opens up walls in an older Hamilton home is often the first real look anyone has had at that home’s wiring in decades, and it’s common to find things that weren’t part of the original renovation scope. Aluminum branch wiring, common in homes built through the mid-1960s to late 1970s, knob and tube wiring in homes built before the 1950s, and panels that are simply undersized or outdated for the home’s current electrical demand all turn up regularly once drywall comes down.
None of this means your renovation has to become a full rewire by default, but it does mean these findings deserve a proper assessment rather than being patched around or ignored because they weren’t part of the original plan. We flag what we find during rough-in and give you a clear picture of what needs addressing now versus what can reasonably wait, so you’re making an informed decision rather than being surprised mid-project.
We review your renovation or addition plans, existing panel capacity, and the specific rooms or spaces involved.
For additions, we calculate whether your existing service can support the added square footage or whether an upgrade is needed alongside it.
We run new circuits for lighting, outlets, and dedicated equipment before drywall goes up, coordinating with your renovation timeline.
We coordinate the ESA rough-in inspection before walls are closed.
Once drywall and finishing are complete, we install outlets, switches, lighting, and any required safety devices.
We test all circuits and coordinate the final ESA inspection, providing documentation for your records.
A poorly planned renovation or addition electrical scope tends to surface as a string of small problems rather than one obvious failure, a kitchen with too few counter receptacles, an addition that trips breakers once fully furnished, or wiring issues discovered after walls are already closed because no one looked closely during rough-in. Watch for an electrician who doesn’t ask about your specific room layouts before wiring a kitchen or bathroom, or who doesn’t calculate load capacity before wiring an addition. A proper renovation or addition electrical scope includes correctly spaced and protected kitchen and bathroom circuits, a documented load calculation for any addition, a flagged assessment of anything found once walls are open, and both a rough-in and final ESA inspection with documentation you can keep on file.
Mercanti Electric provides electrical renovation and addition services throughout:
Get the electrical renovations hamilton trusts, planned around your actual project, not a generic checklist.
Ontario’s electrical code requires kitchen counter receptacles to be spaced so no point along the counter is more than about 1.8 metres from an outlet, with dedicated small appliance circuits and GFCI protection near the sink. We plan this based on your specific kitchen layout.
It depends on your existing panel’s capacity and the added demand from the new space. We calculate this during planning so it’s accounted for in your renovation budget and timeline upfront, not discovered mid-project.
Yes, if the work involves new circuits, added outlets, or rewiring, which most kitchen and bathroom renovations do. An ESA electrical permit and inspection are required.
We flag it and explain what it means for your renovation, options range from a targeted repair to a broader rewire depending on the wiring’s condition and scope. You make the decision with full information, not after the fact.
Yes. We regularly manage electrical scope across multiple renovation phases happening at once, coordinating as one project rather than treating each space separately.
Not necessarily. It depends on the wiring’s type, condition, and how much of it is actually affected by your renovation. We assess this case by case rather than defaulting to a full rewire.
It depends heavily on scope, a single kitchen is a much shorter job than a full addition with a panel upgrade. We provide a specific timeline after the initial assessment.
