Residential & Commercial Electrical Services in Ontario: Safe, Code-Compliant Solutions
Modern properties ask a lot from their electrical systems. Heavy appliances, home offices, smart devices and electric vehicles all draw more power than older wiring was ever designed to carry. Because of that, Proventa Construction provides safe, reliable electrical services in Ontario for new builds, major renovations and system upgrades. Whether you need a simple fixture change or a full rewire, our licensed electrical team delivers code-compliant work.
Safety always comes first. Therefore, we plan each job carefully, use quality materials and test every connection before we finish. We also look for ways to cut your energy use, such as LED lighting and smart controls. As a result, you get a system that protects your property and keeps running costs down.
Power Infrastructure & Upgrades
We upgrade panels, add dedicated circuits and install EV chargers. As a result, your property can handle modern appliances and technology safely.
Interior & Smart Lighting
We install pot lights, smart switches, dimmers and fixtures. In addition, LED lighting lowers your monthly energy use.
Renovation Wiring & Safety
We wire kitchens, bathrooms and basements and install smoke and carbon monoxide alarms. Therefore, your renovation meets code from the start.
Exterior & Security Lighting
We install pathway, patio and floodlight systems with weatherproof outlets. Consequently, your property looks great and stays well lit after dark.
What Our Electrical Services Include
Every property has different needs. However, these are the services clients request most often.
Electrical Panel Upgrades
We replace outdated breaker panels with 100A, 200A or higher service. As a result, your system supports modern appliances and electronics safely.
Dedicated Circuits
High-draw equipment needs its own circuit. Therefore, we install isolated circuits for sub-panels, HVAC systems, heavy machinery and kitchen appliances.
EV Charger Installation
We install Level 2 charging stations in residential garages and commercial parking areas. Moreover, we check your panel capacity first, so the charger runs safely.
Outlets, Switches & Receptacles
We install GFCI outlets, USB wall sockets, dimmer switches and tamper-resistant receptacles. In addition, these upgrades improve both safety and convenience.
Pot Lights & Recessed Lighting
We install sleek, energy-efficient LED pot lights in kitchens, living spaces and hallways. As a result, rooms feel brighter and more modern.
Smart Home Lighting Systems
We set up automated dimmers, smart switches and app-controlled lighting. For example, you can schedule lights or dim them from your phone.
Ceiling Fans & Fixtures
Heavy chandeliers and ceiling fans need solid mounting. Therefore, we install and wire them securely, along with pendants and accent lights.
Kitchen & Bathroom Electrical
We wire dedicated appliance circuits, under-cabinet lighting and vanity fixtures. Moreover, we add moisture-safe GFCI protection where water is nearby.
Basement Electrical Wiring
We handle full rough-in and trim work for finished basements, home offices and secondary suites. Then we test everything before the walls close up.
Smoke & Carbon Monoxide Detectors
We install hardwired, interconnected smoke alarms and CO detectors. As a result, your household gets reliable protection and meets code.
Outdoor & Landscape Lighting
We install pathway lights, patio accents, post lamps and weatherproof outlets. Because of that, your outdoor spaces stay usable and attractive after dark.
Security Lighting
We install floodlights, motion sensors and perimeter lighting. In addition, bright, well-placed lights help deter unwanted visitors.
Signs Your Property Needs an Electrical Upgrade
Electrical problems often start small. However, early action prevents bigger and costlier issues later.
Tripping Breakers & Flickering Lights
Frequent trips or dimming lights suggest an overloaded circuit. Therefore, you should have an electrician check the system soon.
Fuses or an Outdated Panel
Old fuse boxes and small panels struggle with modern demand. As a result, many owners upgrade before adding new appliances.
Knob-and-Tube or Aluminum Wiring
Some older Ontario homes still have these wiring types. Because they can cause safety and insurance concerns, we assess them carefully and recommend a plan.
New Loads on the Way
An EV charger, heat pump, hot tub or large renovation adds demand. Therefore, you should confirm your panel capacity before you buy.
How We Run an Electrical Project
Good electrical work follows a clear process. Here is how we keep every project safe and organized.
1. Consultation & Site Assessment
We visit the property, inspect your existing system and discuss your goals. Then we explain what the project needs.
2. Design & Load Planning
First, we calculate your power demand. Next, we plan circuits, panel capacity and fixture locations to match.
3. Quote & Scheduling
You receive a written scope, pricing and timeline. Moreover, we plan shutdowns carefully to limit disruption to your day.
4. Installation & Permits
We install the system to the Ontario Electrical Safety Code. In addition, we handle Electrical Safety Authority notifications and inspections where they apply.
5. Testing & Final Walkthrough
We test every wire, connection and breaker. Finally, we walk you through the work and clean up the site.
What Affects the Cost of Electrical Services?
No two electrical projects cost the same. Knowing why can help you plan with confidence.
Scope & System Size
A fixture swap costs far less than a panel upgrade or full rewire. Also, larger properties need more cable, circuits and labour.
Age & Condition of Existing Wiring
Older systems often need extra repair work. As a result, a thorough assessment helps us give you an accurate quote.
Access & Finishes
Finished walls and ceilings take more time to open and repair. However, planning the work during a renovation can reduce that cost.
Fixtures & Smart Features
Premium fixtures and smart controls add to the total. Therefore, we help you decide where the upgrades matter most.
Why Choose Proventa Construction for Your Electrical Needs?
Frequently Asked Questions: Electrical Services
Straight answers to the questions clients ask us most often.
Cost, Permits & Timeline
How much do electrical services cost in Ontario?
The price depends on the scope, the age of your wiring and the materials you choose. For example, a fixture swap costs far less than a panel upgrade. After we inspect your property, we give you a clear written estimate.
Do I need an ESA permit for electrical work in Ontario?
Most electrical work in Ontario involves the Electrical Safety Authority, either through a permit or a notification. In addition, an ESA inspector may review the work. We check what applies to your project and handle the process for you.
How long does an electrical project take?
A small job may take a few hours. A panel upgrade usually takes about a day, although it can take longer if repairs come up. We give you a schedule before we start.
Panels, Wiring & EV Chargers
When should I upgrade my electrical panel?
Consider an upgrade if your breakers trip often, you still have fuses or you plan to add major loads. For instance, an EV charger, heat pump or basement suite often needs more capacity. We assess your system and recommend the right service size.
Can I install an EV charger at home?
Usually, yes. First, we check your panel capacity and the distance to your parking spot. Then we install a dedicated circuit and a Level 2 charger. If your panel is near its limit, we recommend an upgrade.
Is knob-and-tube or aluminum wiring dangerous?
Not always, but both can create risks when they age or when someone alters them. In addition, some insurers ask homeowners to replace or upgrade them. We assess the condition and explain your options before any work starts.
Lighting, Safety & Renovations
How many pot lights do I need in a room?
It depends on the room size, ceiling height and how you use the space. As a general rule, we space lights to avoid dark spots and glare. Moreover, we add dimmers so you can control the mood.
Do you install smoke and carbon monoxide alarms?
Yes. We install hardwired, interconnected smoke alarms and carbon monoxide detectors. Because these devices protect your household, we place them where code and good practice call for them.
Can you handle the electrical work for my renovation?
Yes. We wire kitchens, bathrooms and basements as part of renovation projects. In addition, we coordinate timing with other trades, so inspections and finishes stay on schedule.
