Scope

Lighting and outlet work we handle

  • Recessed LED pot lights planned around joists, ducts and insulation
  • Marked ceiling layouts so you can see spacing before any holes are cut
  • Replacement light fixtures, with support for the fixture weight confirmed
  • Switches, dimmers and three-way switch loops matched to LED loads
  • New and replacement outlets, including tamper-resistant and USB-style outlets
  • GFCI and AFCI protection where the Ontario Electrical Safety Code requires it
  • Wiring through finished ceilings and walls using small access holes
  • Permits and ESA notification where required, then testing before we leave

Process

How a lighting job goes in a finished home

Every job starts with a conversation and a look at the equipment. You see the options in plain language before anything is booked.

Request a lighting visit

  1. 1

    Walk the rooms and set the goals

    We look at the room, the ceiling height, how it is used and the existing switches. Brightness, warm or cool colour temperature and dimming preferences are agreed before anything is cut.

  2. 2

    Plan the layout

    Pot lights are spaced to suit joists, ducts, plumbing and insulation, then marked on the ceiling. Moving a light a few centimetres can avoid a duct or beam, so this step is worth doing slowly.

  3. 3

    Run the wiring

    Cable is fished through attics, joist bays or wall cavities with small access holes. Where a ceiling has no attic access, the route can take more time, and we explain that in the quote.

  4. 4

    Install and connect

    Housings, fixtures, switches and outlets are installed and connected by licensed electrical professionals or trade partners, with permits and ESA notification where required.

  5. 5

    Test and hand over

    Every circuit, dimmer and protective device is tested. We confirm dimmer settings, label any new breakers and review the patching and paint touch-ups agreed at the quote stage.

Good to know

Details that make lighting and outlets work well

Pot light choices

New-construction housings suit open ceilings, while remodel housings fit into finished ones. In insulated ceilings, look for IC-rated housings or sealed LED slim discs rated for contact with insulation. Colour temperature and beam angle change how a room feels, so look at a sample if you can.

Switches and dimmers

LED bulbs and dimmers must be compatible, or you get flicker and buzzing. Smart switches often need a neutral wire in the switch box, which some older homes do not have. We check the box before recommending a switch.

Outlets and protection

GFCI protection is required in locations such as bathrooms, kitchen counters, outdoors and other areas near water, and AFCI protection applies to many dwelling circuits under the current code. Exact requirements depend on the room and the code edition in force, so the installer confirms them for each job.

Fixtures and ceiling support

Chandeliers, pendants and ceiling fans need an electrical box rated for their weight and movement. A standard box may not be enough, so we check what is in the ceiling before the fixture is chosen.

Scope and limits

This page covers defined lighting and outlet upgrades in existing homes. Lighting as part of a full renovation, an addition or new construction is outside our controlled electrical scope, and a general contractor or electrical contractor handles the full wiring package. For panel capacity, see panels and circuits.

Questions about Lighting and Outlets

How many pot lights does a room need?

There is no honest number without seeing the room. Spacing depends on ceiling height, how the room is used, the beam angle of the lights and what is above the ceiling. We mark a layout so you can see it before we cut.

Can you add pot lights without removing the ceiling?

Usually, using remodel housings and small access holes, as long as the ceiling cavity can be reached. Some layouts run into ducts, beams or a finished floor above, so the plan may shift. Patching and paint are discussed at quote stage.

Do my dimmers have to match the bulbs?

Yes. LED fixtures and bulbs list the dimmers they work with, and a mismatch can cause flicker, buzzing or limited range. We select dimmers that suit the fixtures you choose.

Is GFCI or AFCI protection required?

Often, depending on the room, the circuit and the code edition. GFCI protection applies to locations such as bathrooms, kitchen counters, outdoors and other areas near water, and AFCI applies to many dwelling circuits. The installer applies the current requirements to your job.

Can you install a fixture I bought myself?

Usually, if the fixture suits the ceiling box and the room. Send photos or the model number before booking so we can check weight, rating and mounting. Use Build My Quote to include them.

Do pot lights leak air into an Ontario attic?

They can if the wrong housings are used. A hole in an insulated ceiling lets warm indoor air reach a cold attic, which can cause heat loss and moisture problems. Airtight, insulation-rated housings or sealed LED slim discs reduce that risk when installed well. We ask about attic insulation and access, then choose housings to suit the ceiling.

Can I add pot lights to a basement ceiling?

Often, but basements have limits. Ceiling height, ducts, plumbing, joist direction and what is above the ceiling decide the layout. A finished drywall ceiling, a drop ceiling and an open ceiling each need a different approach. We mark a layout on the ceiling before any cuts, so you can see the spacing and move lights around ducts.

What colour temperature should I choose for pot lights?

Warm white suits living rooms and bedrooms, while cooler white suits kitchens, laundry rooms and workspaces. Some fixtures let you switch between colours. Look at a sample in the room if you can, because Ontario's short winter days can make a space with the wrong colour feel flat. We agree the colour before anything is installed.

Do I need a permit to add pot lights or new outlets in Ontario?

It depends on the scope. Swapping a fixture is different from running new circuits or adding outlets, and municipal rules vary across the GTA and nearby Ontario. Anyone hired to do electrical work in an Ontario home must be a Licensed Electrical Contractor, and permits and inspections are handled where required by licensed electrical professionals or trade partners. We confirm the details when we quote. Ask before work starts so nothing is left to chance.

Can I add an outlet in a finished basement wall?

Usually, as long as there is a practical route for the cable. Insulated and finished basement walls can make fishing wire harder, and some jobs use surface-mounted options where the code allows. Basement outlets often need ground-fault protection. We look at the wall, the panel and the existing circuits before agreeing on a plan.

Can two-prong outlets in an older home be replaced?

Often, but the safe method depends on what the wiring allows. Older Ontario homes can have ungrounded outlets, and the code sets rules on how they may be replaced, which can include ground-fault protection. An electrical professional checks the circuit and decides the approach. Do not fit a three-prong outlet where there is no ground.

Can pot lights go in a bathroom or near a shower?

Only with fixtures rated for the location. Damp and wet areas need lights marked for that use, and some zones near a tub or shower have stricter rules. Ground-fault protection applies to many bathroom circuits. Tell us the room layout and where the ventilation fan sits, and the installer confirms which fixtures and placement suit the space.
