Potlight Installation Markham: Unionville, Cornell and Markville
In Markham we do two things a lot: whole-home LED retrofits in older Unionville and Thornhill houses, and smart lighting in Cornell homes where owners want Lutron Caseta or Philips Hue from day one. ESA-licensed potlight installation across the GTA with a free drawn-to-scale layout, a fixed written quote and drywall patching included on every job.
Dim Rooms or Dated Cans in Markham? Here's the Fix
Most calls start with one of these. Every one of them is fixable, usually in a single day.
Dated lighting in Unionville's heritage district homes
Halogen cans and tired fixtures leave rooms dim, but owners worry any change will run into heritage rules.
Unionville is one of the city's four heritage conservation districts, and its permit process covers exterior alterations to the houses.
An LED potlight retrofit works from inside the ceilings, and smart dimmers go into existing wall boxes. Any exterior fixture waits until the City's heritage staff have reviewed it.
Swiss cheese ceilings
The last contractor cut holes in the wrong spots and left without patching. We patch every removed fixture, and it's written into the quote.
Buzzing, flickering dimmers
An old dimmer paired with LED fixtures hums at low levels. We match Lutron or Leviton dimmers to the driver so it stays quiet.
Quotes that keep growing
Scope creep once the ceiling's open. Our written quote is fixed, and nothing changes unless you ask for more work.
Unlicensed handymen
Uninsured, unpermitted work can void your home insurance. Every installer is ESA-licensed or supervised, with WSIB and $2M coverage.

What Local and GTA Customers Say
Real jobs from real GTA streets. First names and last initials only, because our clients asked for it that way.
"Another contractor left my kitchen ceiling like Swiss cheese. They patched it, redrew the layout and had eight warm-white slims on a Lutron dimmer by Sunday dinner."
"I'd finished the basement myself and ran out of steam at lighting. Twenty-two potlights on three dimmers, done by 4pm on a Saturday."
"Fourteen 3000K soffit lights on a dusk-to-dawn control, finished before barbecue season. The house looks great from the street."
5-Star Satisfaction is our standard on every job.
LED Retrofit Specialists in York Region
Markham jobs lean two ways: LED retrofits in older Unionville and Thornhill homes, and smart lighting in Cornell, where owners often want Lutron Caseta or Philips Hue control from day one.
Unionville and Thornhill are two of the city's four heritage conservation districts, and exterior alterations there need a heritage permit. Interior retrofits don't touch the facade, so we usually start inside and check any porch or soffit fixture with heritage staff before ordering.
Cornell was planned as a New Urbanist community, with construction starting in 1997. Its newer homes have open ceilings and modern panels, so fixtures and smart dimmers can be planned together and every scene pairs cleanly.
Typical projects here
- Whole-home LED retrofits
- Smart lighting integration in Cornell
Getting to Your Job
We head straight east from our Vaughan workshop along Highway 7 or the 407, which drops us into the Highway 7 corridor, Markville and Unionville quickly. Cornell jobs are reached via 16th Avenue or Major Mackenzie Drive, and Thornhill via Steeles Avenue or Bayview Avenue.
We've worked with local general contractors on new construction since 2010, so we know the area and the supply counters well. If a smart dimmer or bridge needs swapping mid-job, we can usually pick it up the same day.
After your consultation, the written quote and drawn-to-scale layout arrive within 24 to 48 hours.
Homes We Work In
Unionville and Thornhill have plenty of 1970s to 1990s homes with halogen cans, fluorescent kitchen box lights and old incandescent dimmers. These are ideal for whole-home LED retrofits: we pull the old fixtures, recycle the tubes, patch oversized holes and install slim LEDs on matched dimmers.
Cornell is newer and more tech-forward. Owners there often want smart potlights with Lutron Caseta or Philips Hue set up from the start, with scenes, schedules and Google Home or Alexa control. We plan fixtures and smart dimmers together so everything pairs cleanly.
Markville and the Highway 7 corridor mix 1980s detached homes with newer townhomes and condos, where we often do kitchen potlights and main floor potlight installation packages.
Seasonal Planning Tips
Retrofits and smart installs are indoor work, so they aren't tied to the weather and they run all year. Many families here book whole-home retrofits in late fall and winter, when short days make the old lighting feel dimmest and the hydro savings kick in fastest.
Soffit and landscape lighting in Unionville and Cornell can't go in once the ground and soffits freeze, so it's booked April through October. Spring is busiest, and a smart photocell or Caseta schedule means those lights follow the sunset all year.
