Two homeowners in Newmarket ask for an "exterior painting quote" and get two genuinely different jobs. One is a full-surface repaint of an original wood-clapboard house near downtown, shaded most of the day by the mature canopy along the East Holland River and Fairy Lake corridor. The other is a Glenway or Stonehaven-Summerhill home from the 1990s or 2000s with vinyl siding — siding that isn't painted at all, which means the actual job is trim, fascia, soffit, and the garage door. Quoting either one against the other's price is how a homeowner ends up either overpaying or badly underbudgeting.
Why "exterior painting" means different surfaces here
A lot of the older housing stock close to Main Street, Park Avenue, and the streets running down toward Fairy Lake is real wood siding and trim — clapboard, shiplap, or board-and-batten, all of it a paintable surface that needs a genuine repaint cycle. Vinyl siding, standard on most Glenway and Stonehaven-Summerhill builds, is factory-coloured through the material itself and isn't meant to be repainted; manufacturers generally void the warranty if it is, and paint doesn't bond well to vinyl's flexible surface anyway. So on a newer-subdivision home, the paintable exterior is really just the trim board, fascia, soffit, shutters, front door, and garage door — a much smaller job by square footage than a downtown wood-sided house, even though the two homes can be a similar overall size.
Real 2026 pricing
Exterior painting across the Toronto area, Newmarket included, runs $3.00–$6.00 per square foot of paintable surface in 2026, HST (13%) on top. What differs between these two housing types is how much paintable surface there actually is:
- Full-surface repaint, downtown-core wood-sided home (roughly 1,400–1,800 sq ft of siding, trim, soffit, and fascia) — $5,600–$10,800, landing toward the upper part of the per-square-foot range because wood siding needs more scraping, sanding, and priming than any other surface type.
- Trim-only repaint, Glenway or Stonehaven-Summerhill vinyl-sided home (trim, fascia, soffit, shutters, garage door, front door — roughly 300–500 sq ft) — $1,200–$2,800, a genuinely smaller job because the siding itself is never touched.
- Front door and shutters only (either housing type) — $250–$600, a common smaller job on its own between full repaint cycles.
Labour runs $70–$110 an hour in York Region for this kind of work; the gap between the two full-job totals is almost entirely surface area and prep time, not a different rate.
Why the canopy near Fairy Lake changes the repaint cycle
A wood-sided home shaded by mature trees along the East Holland River corridor or backing directly onto Fairy Lake dries more slowly after rain than an open, sun-exposed street in Glenway or Stonehaven-Summerhill — most of which were built on cleared subdivision lots with young or newly-planted trees still decades from real canopy. That extra dampness on a shaded wood surface feeds mildew and algae growth well before the paint film itself has actually failed, showing up first as dark streaking or a dull, blotchy finish. Left long enough, sustained moisture against wood siding accelerates real paint failure — blistering, cracking, peeling — faster than the same paint would fail on a dry, sun-exposed wall. A normal 7–10 year repaint cycle on an open subdivision street tends to run closer to 5–7 years on a shaded, tree-covered lot near the river corridor or lake.
This is the same watershed and tree-canopy reality covered in our piece on deck and fence repair near the Nokiidaa Trail and Fairy Lake — moisture, not sun, is the thing working against exterior surfaces on these lots, and it applies to paint the same way it applies to wood decking.
The tree bylaw question, if prep work needs to cut back a branch
Painting itself never triggers Newmarket's Private Tree Protection Bylaw. But if a painter needs to cut back branches to safely reach siding or trim, and the tree in question is over 20 centimetres in diameter (measured 1.4m above ground), that pruning can fall under the same 2022 bylaw covered in our deck and fence piece — a real permit and fee, scaling from $100 for a single tree up to $5,000 for eleven or more, with dead or hazardous trees fee-exempt. Ask your painter directly whether reaching the siding needs any pruning before work starts, rather than finding out mid-job.
Does repainting need heritage sign-off downtown?
If your home sits inside the Lower Main Street South Heritage Conservation District, covered in detail in our piece on exterior repairs to a Main Street heritage building, the Ontario Heritage Act's Section 42 permit list is specific: new construction, facade or storefront changes, additions, garages, fences, masonry repointing, removing or covering original siding, altering doors and windows, and changes to the roofline. Repainting an existing surface in its existing colour isn't on that list — it's maintenance, not an alteration. Where it gets genuinely unclear is a real colour change on a designated building: heritage conservation district plans generally treat a documented historic colour palette as part of a building's protected character, even when the specific act of painting isn't itself enumerated. If you're planning anything more than a like-for-like recoat inside the district boundary, a call to Planning and Building Services (905-953-5300) before you pick a colour is genuinely worth it — cheaper than repainting twice.
What actually drives the price on a given house
- Surface material — wood siding and trim need scraping, sanding, and spot-priming; a vinyl-sided home's trim-only job skips most of that on the siding itself, since there's no siding to prep.
- Surface condition and shade exposure — a shaded, moisture-prone wall picks up extra prep time compared to a dry one of the same size, which is the real driver behind Fairy Lake and river-corridor homes running toward the top of the per-square-foot range.
- Number of storeys — a two- or three-storey home needs ladders or scaffolding for upper walls; labour is 70–80% of a typical exterior paint job's total cost.
- Paint quality — a premium 100%-acrylic exterior paint costs more per gallon but holds up better against sustained moisture, which matters more on a shaded downtown lot than on an open Glenway street.
Timing it right
Standard exterior latex paint needs a dry surface and air temperature generally above 10°C to cure and bond properly — a narrower window than the 5°C threshold that applies to caulking or glazing work. In York Region that puts the real season for this work at roughly mid-May through early October. A shaded, canopy-covered lot near Fairy Lake or the river corridor should book toward the earlier part of that window rather than the tail end — the same tree cover that slows drying after rain also means the surface takes longer to reach a safe painting temperature on a cool fall morning. A specialty low-temperature exterior formulation can extend that window into November for some products, but it's worth asking your painter directly which paint they're using before booking a late-season job rather than assuming standard latex will hold up.
Match the estimate to the house you actually have
A downtown-core wood-sided home under Fairy Lake's canopy and a Glenway or Stonehaven-Summerhill vinyl-sided home both need real, periodic exterior maintenance — but one is a full repaint job on a shorter cycle, and the other is a smaller trim-only job on a longer one. Ask a contractor to walk the exterior with you and point out exactly which surfaces are getting painted before you compare quotes; a "$3,000 exterior paint job" means something very different depending on which of these two houses it's actually describing.
