What Does an Interior Paint Contractor Do?
The job title is broader than it sounds. A contractor takes responsibility for the finished surface, not just for the hours spent rolling paint.
Scope of the work
An interior paint contractor is a painting company, sole proprietor or franchise crew that is paid to prepare and coat the inside surfaces of a building: drywall and plaster walls, ceilings, trim, baseboards, doors, window casings, closets, stair rails and, on many jobs, kitchen cabinets. The contractor supplies the labor, the tools, the drop cloths and usually the paint itself, and answers for the result.
That last point is what separates a contractor from a day laborer. The Painting Contractors Association (PCA), the trade body that was known as PDCA until 2018, publishes industry standards that define what a properly painted surface looks like. A contractor working to those standards is accountable for hide, sheen uniformity and a clean cut line, not only for showing up.
Residential painting versus commercial painting
Residential painting covers houses, condos, apartments and rental units. Crews are small, typically two to four painters, and the work is scheduled around the people living there. Commercial painting covers offices, retail, medical suites, warehouses and multifamily common areas, and it is often done after hours with larger crews, sprayers and low-odor products such as Sherwin-Williams ProMar 200 Zero VOC or Benjamin Moore Ultra Spec 500.
Many painting contractors offer both, and most do exterior paint work in summer. Exterior paint and interior paint are different products with different prep, so if the project is a single house, a residential specialist is usually the better fit because the cleanup habits are different when customers are living in the space.
What the crew does on-site
A full interior painting project moves through the same steps every time: furniture moved and covered, floors protected, nail holes and cracks filled, trim caulked, glossy surfaces sanded or deglossed, stains and repairs spot-primed, then two finish coats cut in by brush and rolled or sprayed. The crew lead walks the rooms with the customer at the end and touches up anything missed.
On a typical 2,000 sq ft house a three-person crew needs three to five working days for walls and ceilings. Trim, doors and cabinets add time because they need more sanding, more careful masking and longer dry times between coats.
Contractor, handyman or do it yourself?
A handyman can paint a bedroom, and a homeowner can paint a hallway over a weekend. The reasons to hire a dedicated interior paint contractor are height, volume and surfaces that punish mistakes: two-story foyers, whole-house repaints, kitchen cabinets, lacquered trim, and any home built before 1978 where disturbing old paint is regulated.
Labor is the majority of the cost of any paint job, so the trade-off is money against time and finish quality. Where a room needs one coat of the same color, doing it yourself is rational. Where the job involves color changes, ceilings, repairs or more than three rooms, a professional crew's speed and sprayer usually win.
