Painters in Thornhill typically charge about $2.00 to $3.00 per square foot to paint walls, and closer to $4.70 per square foot once you add ceilings, trim, and doors. For a full interior repaint, most homes in Old Thornhill, Thornhill Woods, and the established Markham and Vaughan neighborhoods land between $3,500 and $8,000, with larger estate properties running $8,000 to $15,000 or more. A typical exterior runs $4,500 to $12,000. Those numbers are before HST, and they assume premium paint, real prep, and two full coats. The exact figure depends on ceiling height, the amount of trim, and the condition of the surfaces I find when I walk the home.
I have been painting homes in this community for two decades. Most Thornhill homeowners I meet care more about getting the job done right than about finding the lowest bid. Every job is backed by WSIB-covered crews, a $2M liability certificate I hand you before any work starts, and a tiered warranty: lifetime on interior work, three years on exterior, and five years on cabinets. We hold a 5/5 Google rating built over 20+ years of work across this area.
The housing here covers a wide range. You have grand estate homes with 20-foot ceilings and custom millwork, heritage properties in Old Thornhill Village with original plaster, and newer detached homes spread across Thornhill Woods with modern open layouts. Each type needs different prep, and pricing one accurately means knowing which you are standing in.
What makes Thornhill homes distinctive
The housing stock here was built across several eras, and a century plaster home off Yonge takes a completely different work plan than a 2005 build in Thornhill Woods.
The heritage conservation district in Old Thornhill, centred along Yonge Street, holds some of Ontario's oldest residential architecture. These are genuine century homes with original plaster, lath walls, real wood trim with decades of paint already on it, and sightlines that matter to the neighbourhood. They paint nothing like a new build. The plaster cracks along stress lines, old oil-based trim requires a proper bonding primer so water-based coats stick, and settled door frames mean caulk lines that have to be cut and redone by hand. We have painted estate properties, family homes, and character cottages in this historic district, and every one asks for patience and repair before any colour goes on.
Thornhill Woods, on the Vaughan side west of Yonge, leans toward larger newer detached homes built from the 1990s through the 2010s. These are executive and monster homes with open main floors, two-storey foyers, high ceilings, and modern architectural details. The newer builds here have good bones and clean drywall, but the sheer volume of wall and the height of the foyers is what drives the labour, not the room count.
The established neighbourhoods east of Yonge in Markham side include Royal Orchard, Brownridge, German Mills, Grandview, and Uplands. These are mature communities with a mix of heritage character homes and substantial detached properties built through the 1980s and 1990s. Many of these homes are hitting the 15 to 20 year mark, which means it's time for a proper repaint. The original builder-grade paint has thinned and faded, and the surfaces need fresh primer and quality topcoats. A lot of these properties wear brick on the lower storey with stucco above, or stucco detailing around windows and gables. Brick and stucco are not the same paint job, and I plan the product and the sampling before committing to a colour.
What painting a Thornhill home is really like
Yonge Street splits Thornhill into two halves, and the age and type of home set the work plan. Old Thornhill Village needs patience and repair. Thornhill Woods and the newer estates need reach and a safe way to get at the high walls. The established Markham and Vaughan neighborhoods need care with mixed materials and solid surface prep. Which one I'm standing in changes the whole quote.
On the older heritage properties near Yonge in the conservation district, the work starts with prep, not paint. Original plaster cracks along stress lines, old trim often has a century of paint built up on it and needs a bonding primer so the new water-based coat sticks, and settled door frames mean caulk lines that have to be cut and redone by hand. I budget more prep hours on a century home than I do on a build twice its square footage, and I tell homeowners that upfront so the quote makes sense. Rushing a heritage interior is how you end up with peeling trim by the next winter.
The newer detached estates in Thornhill Woods are a different animal. A two-storey foyer with an open staircase and a 19-foot wall is common in these builds, and those walls eat paint. The square footage hides above your eyeline, so a room that feels normal at floor level can hold half again the paint you'd guess. Reaching it safely means scaffold or tall extension ladders over a stairwell, sometimes a custom setup, and that's labour and care, not just a taller stick. I'd rather build the platform properly than have someone over-reaching above hardwood.
The established Markham and Vaughan side homes are solidly built with real maintenance needs. Exterior work here often mixes brick with stucco, and I approach each surface differently. Stucco is porous and thirsty, it needs the right masonry-friendly product and often a sealing coat, and it shows colour warmer than the brick it sits beside. I sample both surfaces in daylight before I commit, because a colour that looks right on the brick can drift on the stucco above it. Get that wrong and the front of the house reads patchy from the curb.
Access and scheduling matter across all three zones. Many properties run deep with mature landscaping, long driveways, and grading that doesn't sit flat for a ladder, so I plan staging and protection before a brush comes out. Thornhill sits in a climate belt where evenings cool off fast and morning dew lingers, which narrows the dry window for exterior coats. I schedule exterior work around that, not against it. Homeowners here pay attention to how the street reads, especially around the heritage district, so I treat the finish the same way they do.
Thornhill's heritage core versus its mid-century streets
Thornhill is split down Yonge Street between Markham and Vaughan, and it is also split by era in a way few GTA communities are. The heritage conservation district along old Yonge holds nineteenth-century houses. A few streets away, Royal Orchard, Thornlea, and Grandview are largely 1950s through 1970s: sidesplits, backsplits, and long low ranch bungalows.
Both are older housing, and people assume they need the same treatment. They do not. The heritage homes carry original plaster and genuine wood trim under many layers of paint, some of it oil, and the prep is delicate and slow. The mid-century houses are drywall and softwood trim, sound and straightforward, but they come with their own signature: long uninterrupted wall runs, split levels that put a stairwell wall at an awkward height, and original trim profiles worth preserving rather than filling.
Where they meet is colour. Thornhill streets have mature tree cover, which pulls green into daylight on north elevations and makes cool greys read considerably colder than they do on an open lot. It is worth sampling on the actual wall here more than almost anywhere else in York Region.
Tips for painting a Thornhill home
In the heritage district, assume the trim is oil until tested. A two-minute test tells you, and it decides whether the new coat holds or peels by spring. Our guide on how to tell if paint is oil or latex covers the method.
On sidesplits and backsplits, plan the stairwell separately. The half-level stairwell wall is the one that goes wrong, because it is too tall to reach comfortably and too short to justify a setup people are willing to pay for. It still needs one.
Account for the tree canopy in colour choice. Mature Thornhill streets throw a lot of reflected green onto north-facing rooms. Cool greys can turn noticeably colder than the sample suggested.
On heritage exteriors, do not power wash by default. Aged wood siding and original mortar do not always take pressure well. Sometimes the right call is a hand wash and careful scraping, which is slower and belongs in the quote honestly.
How long a Thornhill paint job should last
Eight to twelve years is the working exterior range with proper prep. In Thornhill the mid-century homes generally sit comfortably inside it. The heritage properties along Yonge are the ones where the honest answer is shorter, because original wood siding and century-old substrates move more and hold moisture differently than modern cladding does. That is the trade for owning one, and it is manageable when the prep is budgeted rather than skipped.
Interiors run well past a decade on sound surfaces. The Thornhill interior pricing guide and exterior painting rates set out the pricing, and the painter hiring checklist is a fast way to tell whether a painter has actually worked on heritage stock or only says so.
What we do in Thornhill
Thornhill straddles the Vaughan and Markham boundary, so a lot of our week runs across all three. If your property sits on the other side of the line, our Vaughan painters, Markham painters, and Richmond Hill painters pages cover those areas.
Interior painting
We do everything from a single room refresh to a complete estate repaint. Most Thornhill jobs involve high ceilings, open staircases, or extensive crown moulding, which means proper surface prep and careful cut lines. The open main floors common in Thornhill Woods and the newer estate builds mean one colour often flows across the foyer, kitchen, and great room without a break, so I plan the cut lines and the order of rooms carefully to keep the finish even across all that connected wall. On the older heritage homes in Old Thornhill I budget extra time to repair plaster and prime aged trim before any colour goes on.
Interior painting in Thornhill typically runs $3,500 to $6,500 for a standard 3-bedroom home, before HST. Estate properties with high ceilings and more rooms generally fall in the $8,000 to $15,000 range. We give you a firm number after walking through your home.
Exterior painting
Thornhill properties need exteriors that handle our winters and still look sharp. We do complete prep, including power washing, scraping, caulking, and priming, before a single coat of finish goes on. We use weather-resistant products rated for Ontario's freeze-thaw cycles. Because so many homes here pair brick with stucco, I match the product to the surface, a breathable masonry-grade coating for the stucco and the correct prep for the brick, and I sample colours on both before committing. Out across Thornhill the air cools and damp settles in early, so I schedule exterior coats around the dry window rather than push paint onto a surface that won't cure.
A standard Thornhill exterior runs $4,500 to $7,500 before HST. Estate homes with more trim and complex rooflines run higher. Trim-only refreshes start around $2,500.

Professional door painting
Painting doors is one of the cheaper changes you can make to a home, and it shows from the curb. A repainted front door updates the entrance, and fresh interior doors lift the look of the whole house. We sand, prime, and apply two coats of durable trim paint for a smooth finish.
Front door painting runs $200 to $450 depending on size and material. Interior door packages for a full home typically run $1,200 to $3,000, before HST.
door refinishing for Thornhill homes
Cabinet painting
Instead of spending $25,000 to $40,000 on new cabinets, a refinish gives you a new look for far less. We clean, sand, and prime the doors and frames, then apply two coats of a durable finish. Thornhill cabinet painting typically runs $3,500 to $7,500 before HST, depending on kitchen size, and it carries our five-year cabinet warranty.
How we quote in Thornhill
I estimate in person, and on the heritage homes that means testing trim and looking at substrate condition rather than measuring rooms and multiplying. The price you get is fixed and written. Crews are WSIB-covered, the $2M liability certificate is handed over before work begins, and the warranty is lifetime interior, three years exterior, five on cabinets, on paper. Full terms are on the our workmanship warranty.
The questions to ask before hiring a painter covers what to ask any painter. In the heritage district, add one more: ask what they intend to do about the existing oil trim.

Old Thornhill, particularly the heritage conservation district along Yonge, sits on original plaster and lath structures that are decades old. These homes breathe differently than new drywall, and they need breathable primers and careful surface repair before paint goes on. Rushing prep on a heritage home is how you trap moisture and cause peeling by next season. I budget extra time for plaster repair and bonding primer on these properties.
Yes. Many Thornhill properties, especially the established estates and newer builds, combine brick base with stucco detailing or stucco accent trim. Each surface drinks paint differently and needs its own primer and product. I sample on both materials before committing a colour, because the same gallon can read warmer on stucco than on brick beside it. Getting that right is the difference between a tidy refresh and a patchy one.
