Painting 101 — What Every Canadian Homeowner Should Know

Understanding painting costs helps you budget and evaluate quotes. A single room (walls only) typically runs $300-$800, depending on size, ceiling height, and prep work. Multiple rooms bring the per-room cost down. A full house interior averages $3,000-$8,000 for a standard 3-bedroom home.

Exterior painting is a larger investment, typically $3,500-$10,000+ depending on house size, number of storeys, siding material, and condition. Homes with peeling paint or wood rot require more prep, which adds to the cost.

Cabinet painting is specialty work. Expect $3,000-$7,000 for a full kitchen, as it requires careful disassembly, sanding, priming, and multiple coats with a smooth factory-like finish.

Commercial projects are priced per square foot, typically $2-$6/sq ft depending on scope, access requirements, and off-hours scheduling.

When comparing quotes, make sure each includes the same scope: number of coats, paint quality, prep work, and cleanup. The cheapest quote often skips proper prep, which shows within a year.

DIY painting works well for small, low-stakes projects: a single room, an accent wall, or touch-ups. You'll save on labour but spend more time, and the finish won't match professional quality.

Hire a pro when the job involves: whole-house interiors, exterior work, high or vaulted ceilings, stairwells, cabinet refinishing, or any situation where prep work and finish quality matter. Professional painters are faster (a crew of 2-3 can paint an entire house interior in 2-3 days), have better equipment, and know how to handle tricky surfaces.

Exterior painting almost always warrants a professional. It requires ladders or scaffolding, proper surface prep (power washing, scraping, caulking), and knowledge of weather windows. A bad exterior paint job can lead to premature peeling and costly re-dos.

Cabinet painting is the strongest case for hiring a pro. The difference between a DIY cabinet job and a professional one is immediately visible. Pros spray cabinets for a smooth, durable finish that brush marks can't match.

Interior painting can be done year-round since temperature and humidity are controlled indoors. However, there are better and worse times to schedule:

Spring and fall are the busiest seasons for painters. If you want better pricing and faster scheduling, consider booking during winter months (January-March) when demand is lower.

Plan for proper ventilation. Even low-VOC paints benefit from open windows, so mild weather helps. In winter, you can still paint — just run the HVAC and use fans to circulate air.

Allow 2-4 hours between coats for latex paint, and 24 hours before moving furniture back against walls. Most rooms need two coats for full coverage, especially when changing colours dramatically.

For whole-house projects, professional crews typically work room by room, allowing you to continue living in the space. Expect 2-5 days for a full house interior with a crew of 2-3 painters.

Exterior painting in Canada has a limited season due to weather. The ideal conditions are:

Temperature above 10°C (both during application and for 24-48 hours after). Most exterior paints won't cure properly below this threshold. Some specialized products work down to 5°C, but results are better in warmer conditions.

Dry weather with no rain expected for at least 24-48 hours after painting. Painting on damp surfaces or before rain leads to adhesion failure and peeling.

The practical painting season in most of Canada runs from late May through September. In British Columbia and southern Ontario, you might stretch from April to October. In the prairies and northern regions, the window is shorter.

Avoid painting in direct, intense sunlight as it causes paint to dry too quickly, leading to brush marks and poor adhesion. The ideal condition is overcast or working on the shaded side of the house.

Book exterior painters early — by February or March — for the best scheduling. The most reputable painters are fully booked by May.

Choosing the right paint and finish is just as important as the application.

Latex (water-based) paint is the standard for most residential work. It dries quickly, has low odour, cleans up with water, and provides excellent durability. Use it for walls, ceilings, trim, and exteriors.

Oil-based paint is less common now but still preferred for certain applications: high-moisture areas, surfaces that need maximum durability, and some trim work. It takes longer to dry and requires mineral spirits for cleanup.

Paint finishes from least to most sheen: Flat/Matte (hides imperfections, best for ceilings and low-traffic areas), Eggshell (slight sheen, good for living rooms and bedrooms), Satin (moderate sheen, great for kitchens, bathrooms, and hallways), Semi-Gloss (durable and easy to clean, ideal for trim, doors, and cabinets), and High-Gloss (maximum durability, best for doors and high-touch surfaces).

For exterior work, 100% acrylic latex is the gold standard. It expands and contracts with temperature changes, resists cracking, and holds colour well.

Quality matters enormously. Premium paints (Benjamin Moore, Sherwin-Williams, Dulux) cover better, last longer, and look better than budget options. A pro using quality paint will deliver results that last 8-10 years versus 3-5 years with cheap paint.

Good preparation makes the job go faster and produces better results. Here's what homeowners should do before painters arrive:

Move furniture away from walls — at least 3-4 feet. For whole-room painting, move everything to the centre and cover with drop cloths, or move it to another room entirely.

Remove wall hangings, picture hooks, curtain rods, and switch plate covers. Painters can do this, but it saves time (and your bill) if you handle it first.

Clear the work area of fragile items, plants, and personal belongings. Paint splatter happens, even with careful masking.

If painting the exterior, move patio furniture, planters, and vehicles away from the house. Trim any bushes or branches touching the siding.

For cabinet painting, empty all cabinets and remove everything from countertops. The kitchen will be unusable for 3-5 days during the process.

Secure pets in a safe area away from the work zone. Paint fumes (even low-VOC) and wet surfaces are hazards for animals.

Professional painters handle masking (taping off trim, protecting floors), surface prep (filling holes, sanding, priming), and cleanup. But clearing the workspace is the homeowner's responsibility and keeps the project on schedule.

Cabinet painting is one of the most cost-effective kitchen upgrades. A professional cabinet paint job costs $3,000-$7,000 — a fraction of new cabinets ($15,000-$40,000+) while delivering a dramatic transformation.

Not all cabinets are good candidates for painting. Solid wood and MDF cabinets paint beautifully. Thermofoil (vinyl-wrapped) cabinets can be painted but require special primers. Heavily damaged or warped cabinets should be replaced rather than painted.

The professional process involves: removing all doors, drawers, and hardware; cleaning and degreasing all surfaces; sanding to create adhesion; applying bonding primer; spraying 2-3 coats of durable enamel paint; and reinstalling with new hardware if desired.

Spray application is essential for a factory-smooth finish on cabinets. Brush and roller marks are the hallmark of a DIY job. Professional painters use HVLP sprayers in a controlled environment.

Popular cabinet paint choices include Benjamin Moore Advance, Sherwin-Williams Emerald Urethane, and Dulux Diamond. These are self-leveling, durable, and designed for high-touch surfaces.

The cure time for cabinet paint is 2-3 weeks. During this period, treat surfaces gently — avoid slamming doors or scrubbing. After full cure, well-painted cabinets will last 8-10 years with proper care.

Always hire a specialist for cabinet work. General painters may offer to do cabinets, but the technique, equipment, and product knowledge are specialized. Ask to see photos of previous cabinet projects before hiring.
