Potlight Installation Toronto provides halogen potlight replacement, fluorescent box light removal, whole-home LED retrofits, and LED-compatible dimmer rewiring throughout Toronto, Ontario, backed by 22 years of ESA-licensed residential electrical work across the GTA. Retrofits replace old halogen MR16 or incandescent cans and fluorescent fixtures with modern canless LED potlights. We remove the old fixtures safely, bag fluorescent tubes that contain mercury for proper disposal, and patch drywall wherever the old cavity doesn't match the new potlight size. Old dimmers get swapped for LED-compatible models so nothing buzzes. 5CCT selectable fixtures let us set colour temperature on site. Whole-home retrofits of 25 to 40 lights in a two-storey house start at $2,800. Single-room retrofits run 15 to 30 percent above equivalent new-install work because of the patching and rewiring. Most whole homes take one to two days. Here's what a typical retrofit looks like. A 1960s Kingsway bungalow still has yellowed 6-inch halogen cans in the living room and a fluorescent box light in the kitchen that flickers every cold morning. We pull them all, bag the tubes for recycling, patch the oversized openings and set slim 3000K LEDs on new Lutron dimmers. The old halogens ran hot enough to warm the attic. The new ones barely get warm, and the hydro bill drops the next month. 1-2 Days Whole HomeMercury Tube DisposalDrywall Patching IncludedEtobicoke Bungalows ![Electricians removing old halogen housings and bagging fluorescent tubes](/images/content/two-electricians-removing-old-halogen-pot-light-ho.webp) ### Every led potlight retrofit and old fixture removal job includes - Halogen and fluorescent fixture removal - Mercury tube disposal - Drywall patching of oversized cavities - LED-compatible dimmer rewiring - Whole-home packages for two-storey homes No Hidden Costs ## How Much Does LED Potlight Retrofit and Old Fixture Removal Cost in Toronto?

Here’s what we pull out and what goes in its place. ### Halogen MR16 and incandescent cans Common in 1990s and 2000s homes across Richmond Hill, Markham and Mississauga. They run hot, burn out often and use four to five times the power of LED. We replace them with canless LED wafer potlights [/ →](/) . ### Fluorescent box lights and troffers The big rectangular fixtures in older kitchens and basements, especially in 1960s and 1970s bungalows in Etobicoke and Scarborough. They flicker in the cold and the ballasts hum. We remove them, recycle the tubes and patch the large opening. ### Old recessed housings that aren’t air-tight Older housings leak warm air into the attic in winter, which wastes heat and can cause ice damming. New canless LEDs are air-tight and IC-rated. ### Failing LED retrofit bulbs Some homes had screw-in LED bulbs put into old cans. They often flicker on old dimmers. We replace the whole fixture for a cleaner, longer-lasting fix. ## How Much Does an LED Potlight Retrofit Cost in Toronto? Whole-home retrofits of 25 to 40 lights start at $2,800. Single rooms run 15 to 30 percent above the new-install price. Here’s what moves it. | Cost factor | Lower end | Higher end | | --- | --- | --- | | Old hole size | Matches new 4-inch fixture | Oversized 6-inch, needs patching | | Fixture type | Halogen cans | Large fluorescent box lights | | Dimmers | Few dimmers to replace | Every room needs new dimmers | | Ceiling | Standard drywall | Plaster or tested stucco | | Scope | Single room | Whole two-storey home | Patching, disposal and dimmer swaps are always included, and your written quote shows every line. ## When Is It Time for an LED Retrofit? If you’re replacing halogen bulbs every few months, it’s time. The same goes for fluorescent fixtures that take a few seconds to turn on during cold winter mornings, or dimmers that buzz. Many people also retrofit before listing a home in spring, because bright, even light photographs well. Others wait until an attic insulation upgrade, since air-tight LEDs help keep the heat in. ## Common Retrofit Problems We Fix ### Rings and gaps around new lights The previous installer dropped a smaller LED into a big old hole. We patch properly or use a trim that covers the opening fully. ### Flicker after switching to LED bulbs An old dimmer paired with LED. We replace the dimmer with a matched model. ### Hot attic and ice dams Leaky old housings let heat escape. New air-tight IC-rated fixtures seal the ceiling. ### Mixed colour temperatures room to room Years of random bulb replacements. We standardise on one colour temperature, or use 5CCT fixtures and set each room on purpose. ## LED Retrofit vs. Swapping Bulbs Screw-in LED bulbs are cheap and easy, but they don’t fix leaky housings, mismatched dimmers or yellowed trims. They also run hot inside an old can and often fail early. A full retrofit replaces the whole fixture with a slim, sealed LED on a proper dimmer. It costs more upfront but it’s done once, looks cleaner and saves more power over time. Ready to ditch the halogens? Book a free consultation and we’ll count every fixture and quote the whole home. Why Homeowners Pick Us ## Why Choose Potlight Installation Toronto for LED Retrofit? ### Patching is part of the job Old 6-inch halogen holes rarely match a new 4-inch LED. We patch every mismatch so you're not left with rings around the lights. ### Safe disposal Fluorescent tubes contain mercury. We bag and recycle them properly, along with old ballasts. ### Dimmers that match Old incandescent dimmers make LEDs flicker. We swap them for Lutron or Leviton LED-compatible dimmers. ### Real energy savings A 50-watt halogen becomes a 9 to 12-watt LED. On a 30-light home, that's a noticeable drop on your hydro bill.

A whole-home retrofit of 25 to 40 lights in a two-storey house starts at $2,800. That includes removing the old fixtures, recycling fluorescent tubes, patching oversized openings, new LED potlights and LED-compatible dimmers. Your fixed written quote depends on the number of fixtures and how much patching the old openings need. Why do retrofits cost more than new installs? Retrofits run 15 to 30 percent higher than equivalent new-install work because we're doing extra steps: taking out old housings, disposing of tubes and ballasts, patching holes that don't match the new size and rewiring dimmers. New installs start with a clean ceiling, so there's less labour involved. Can you reuse my existing potlight holes? Sometimes. If your old openings are 4 inches, a canless LED can often drop right in. Most older halogen cans are 5 or 6 inches, though, so we either use a larger LED trim to cover the hole or patch it down to size. We'll tell you which during the audit. What happens to my old fluorescent tubes? Fluorescent tubes contain a small amount of mercury, so they shouldn't go in household garbage. We bag them carefully during removal and take them to a proper recycling depot, along with old ballasts. It's included in your retrofit price. How much will I save on hydro? A typical halogen pot uses about 50 watts, while an LED potlight uses 9 to 12 watts for similar light. On a 30-light home, that's roughly 1,200 watts less every hour the lights are on. Savings show up quickly, especially during long winter evenings from November to February. My stucco ceiling is from the 1970s. Is that a problem? Stucco or popcorn ceilings from the 1960s to 1980s can contain asbestos. Before we cut into one, we'll ask you to get a quick test done. If it's clear, we go ahead as normal. If not, a certified abatement company handles it first. It's a small step that keeps your family safe. Do I need new dimmers with LED potlights? Almost always. Old dimmers were built for incandescent and halogen bulbs, and they cause LEDs to buzz, flicker or not dim fully. We replace them with LED-compatible Lutron or Leviton dimmers matched to the fixture driver, and that's included in the retrofit price. Can you retrofit one room at a time? Yes. Single-room retrofits are common, especially kitchens and basements. They're priced 15 to 30 percent above the equivalent new-install price for that room. Many clients start with the kitchen and come back for the rest of the house later in the year.
