Should I buy my own paint or let the painting contractor supply it for my NB project?

In most cases, letting your painting contractor supply the paint is the smarter choice — they have trade accounts, know exactly what quantities are needed, and are accountable for the product they put on your walls. That said, there are specific situations where buying your own paint makes sense, and it is worth understanding both sides.

When a professional painter supplies the paint, they are taking on responsibility for the product selection, mixing, and colour matching. If the paint fails, peels, or does not cover properly, they cannot point to a different product as the cause — they own the entire result. This matters more than most homeowners realize. Painters also have trade pricing at Benjamin Moore, Sherwin-Williams, Dulux, and Cloverdale stores in Moncton, Fredericton, and Saint John — typically 15-30% below retail. A good contractor will pass some of this saving on through competitive pricing, or simply factor it into their quote. Either way, they are sourcing paint efficiently.

Professional painters also know exactly which products work best for specific conditions. An experienced NB painter knows that a 100-year-old clapboard house in Saint John near the Bay of Fundy needs a different exterior product than a newer vinyl-sided bungalow in Riverview, and they will spec accordingly. They understand which primers are necessary over which surfaces, how many litres a particular product requires per 100 square metres, and how to account for waste and second coats. Estimating paint quantities incorrectly is one of the most common homeowner DIY mistakes — running out mid-wall and needing a new tinted batch that does not quite match the first is a frustrating and costly error.

When buying your own paint makes sense:

If you have already invested significant time selecting a very specific colour — perhaps you have been matching a custom colour from a fabric swatch or re-ordering the exact same tint from a previous project — buying it yourself and supplying it to the contractor is perfectly reasonable. Make sure to get enough. The general rule is one litre per 10 square metres (roughly 4 litres per average room) for two coats on smooth walls, but ask your painter to confirm the quantity before you buy.

If you have a paint loyalty, store credit, or a sale you want to take advantage of at a specific store, go ahead — most painters will work with homeowner-supplied paint. Just understand that if the coverage or outcome is not what you hoped, the painter's responsibility is limited to the quality of their application, not the product itself. Get this understanding in writing.

What to discuss with your contractor either way:

Ask them which product they plan to use and why. A professional should be able to tell you the specific product name and sheen — not just 'a good exterior latex' but 'Sherwin-Williams Duration Exterior, satin finish.' If they cannot or will not answer, that is a yellow flag. Ask whether their quote includes primer, and if so, what primer. Ask if two finish coats are included. These details, regardless of who supplies the paint, determine the quality and longevity of the result.

For most NB homeowners doing a bedroom, living room, exterior repaint, or full interior — let the painter handle the paint. You are hiring expertise, not just labour. For a specific accent colour you have agonized over, or a leftover gallon you want used up on a utility room, supplying it yourself is fine. Just communicate clearly upfront so there are no surprises on either side.
