What this means in Ajax
The pricing ranges in this guide reflect Ontario-wide data, but Ajax homeowners should account for Durham Region market conditions when budgeting. Labour rates for licensed tradespeople in Durham Region — fully WSIB-covered and carrying minimum $2M liability insurance — sit at the upper end of provincial ranges in the GTA. The most meaningful cost variable is rarely the hourly rate; it's whether the work is done correctly the first time.
Ajax's established residential communities along Bayly Street and newer northern subdivisions generate consistent demand for seasonal maintenance — snow removal, lawn care, and eavestrough cleaning — as well as interior renovation projects as families invest in established homes.
Interior painting is one of the most transformative and highest-ROI home improvements an Ontario homeowner can make — and one of the most widely misquoted. Prices vary based on ceiling height, surface condition, number of colours, and whether trim and ceilings are included. Here's a clear breakdown of what professional interior painting actually costs in Ontario in 2026.
Interior Painting Cost per Room in Ontario (2026)
| Small bedroom (walls only) | $300 – $500 |
|---|---|
| Standard bedroom (walls + ceiling) | $450 – $700 |
| Living room / dining room | $500 – $900 |
| Kitchen (walls only) | $350 – $600 |
| Bathroom (small, walls only) | $250 – $450 |
| Hallway and stairwell | $400 – $800 |
| Whole home (3-bedroom) | $3,500 – $6,500 |
| Whole home (4-bedroom) | $5,000 – $9,000 |
What's Included in a Professional Paint Job?
- Surface prep: Filling nail holes, light sanding, masking trim and fixtures
- Primer coat: Required on new drywall, major colour changes, or stained surfaces
- Two finish coats: Industry standard for full, even coverage
- Clean-up: Removing tape, covering furniture, cleaning paint lines
- Paint: Typically included by the painter (and marked up 10–20%) unless arranged otherwise
What's NOT Usually Included (Costs Extra)
- Moving furniture (some painters charge $50–$150 extra)
- Ceiling painting if quoted for walls only
- Trim, baseboards, and door painting (usually quoted separately)
- Accent walls with specialty finishes (Venetian plaster, textured, etc.)
- Extensive drywall repair before painting
- Popcorn ceiling removal
| Trim painting (per linear foot) | $2 – $4 / lf |
|---|---|
| Door painting (per door, both sides) | $80 – $180 |
| Ceiling painting (per room) | $150 – $300 |
| Popcorn ceiling removal + repaint | $3 – $7 / sq ft |
| Primer coat (per room, extra) | $100 – $200 |
Factors That Change the Final Price
- Ceiling height: 9-foot ceilings cost 10–15% more than standard 8-foot; vaulted or cathedral ceilings significantly more
- Surface condition: Walls with significant damage, texture removal, or multiple coats to cover dark colours add time and cost
- Colour change magnitude: Going from dark to light (or vice versa) requires more coats and sometimes multiple primer applications
- Paint quality: Contractor-grade paint vs. premium brands (Benjamin Moore, Sherwin-Williams) differs by $20–$50/gallon — premium paint is usually worth it for finish and durability
- Access difficulty: Stairwells and vaulted ceilings require scaffolding or extension ladders — add 20–40% for complex access
DIY vs. Professional Painting: Which Saves More?
DIY interior painting materials for a standard bedroom cost $150–$250 (paint, primer, rollers, tape, drop cloths). Labour saved is $300–$700 — but the real cost of DIY is time (2–3 days for a thorough job) and finish quality. Professional painters work faster, achieve cleaner lines, and leave no roller texture artifacts. For investment properties or pre-sale painting, professional results consistently yield better returns.
Pro tip: Schedule interior painting in late fall or early spring when painters are less busy. Summer (renovation season) commands peak rates. A September or October booking can save 10–20% on the same job.

Ajax: common questions
How do Ajax prices compare to the rest of Ontario?
Ajax sits within the GTA premium range — labour costs for licensed trades are among the highest in Ontario, reflecting demand density and cost of living in Durham Region. Expect rates at the upper end of the guide's ranges. Pro Tasker's transparent pricing is confirmed upfront for every Ajax booking.
Are these contractors WSIB-insured in Ajax?
All Pro Tasker professionals serving Ajax carry active WSIB coverage — mandatory under Ontario law for any trade contractor. We provide clearance certificate numbers on request. Hiring a contractor without WSIB coverage in Ontario exposes the homeowner to liability for any workplace injury on their property.
