Sherwin-Williams Duration typically costs about $75-$115 per gallon before tax, with many buyers paying around $95 at standard retail pricing. The final price depends on whether the paint is Duration Home interior or Duration exterior, the finish, local pricing, and any contractor discount or sale.
| Item | Low | Average | High | Notes |
|---|---|---|---|---|
| Duration paint, per gallon | $75 | $95 | $115 | Varies by product, finish, store, and promotion |
| Five-gallon purchase | $375 | $475 | $575 | Before tax; bulk pricing may differ |
| Paint for 400 sq. ft., two coats | $150 | $190 | $230 | About two gallons at roughly 350-400 sq. ft. per gallon per coat |
What a gallon of Duration paint usually costs
For budgeting, use $85-$105 per gallon as a practical planning range for many standard Duration purchases, while treating $75-$115 as a broader retail range. Duration Home is formulated for interior use, while Duration exterior is designed for outdoor surfaces; their prices can differ, and color, sheen, and local inventory can affect the quote.
These are paint-only estimates, not installed prices. Sales, account pricing, and contractor discounts can move the actual charge below typical shelf pricing. Confirm the exact product name and finish on the estimate, since “Duration” covers more than one paint line.
Assumptions: U.S. retail purchase, standard gallon container, before sales tax, primer, supplies, or labor.
How paint, prep materials, and labor shape the quote
A painting estimate can include more than the Duration cans. The following ranges show common cost components; labor varies with room layout, surface condition, access, and local rates.
| Quote item | Typical price | Pricing basis | What changes it |
|---|---|---|---|
| Duration paint | $75-$115 | Per gallon | Interior or exterior line, finish, sale |
| Primer | $25-$65 | Per gallon | Stain-blocking or specialty primer |
| Prep supplies | $20-$100 | Per room or job | Caulk, tape, patching compound, covers |
| Professional labor | $1.50-$4.00 | Per sq. ft. of painted surface | Repairs, trim detail, height, number of coats |
| Removal and disposal | $25-$150 | Per job | Old coating, masking, and waste volume |
Paint is only one part of a professional painting bill. Labor may be quoted by the room, by the project, or by painted surface area, so compare what each quote includes before judging the total.
Coverage, coats, and finish can change gallon needs
One gallon commonly covers about 350-400 square feet on a smooth, previously painted surface for one coat. Rough siding, porous drywall, heavy color changes, and textured walls can reduce coverage to roughly 250-350 square feet. Two coats usually double the paint requirement; windows, doors, and unpainted areas reduce the amount needed.
For example, a 400-square-foot wall area may take about two gallons for two coats at normal coverage, or more if the surface is absorbent. A deep color, high-contrast repaint, or repaired wall may also need primer. Estimate gallons from the paintable area and planned coats, then add a modest allowance for touch-ups.
Sheen can affect the price and the appearance of wall imperfections. Matte, satin, and semi-gloss options may not have identical shelf prices, and trim or kitchens may call for a different finish than bedrooms. Ask the store to price the precise sheen and product rather than relying on a generic Duration per-gallon figure.
Interior and exterior Duration prices are not interchangeable
Duration Home is intended for interior walls and trim, while Duration exterior products are selected for outdoor siding and other approved exterior surfaces. Exterior jobs can require additional prep, primer, ladders, or scraping, so the installed project may cost considerably more even when the paint-only price is similar.
Compare the label, intended surface, and finish when reviewing alternatives. A lower-priced interior paint is not a like-for-like substitute for exterior exposure, and an exterior formulation should not be assumed suitable for every indoor use. Match the product to the surface before comparing gallon prices.
Regional paint prices and painter rates vary
Retail prices and labor charges differ by market. As a rough planning adjustment, high-cost metropolitan areas may run 10%-25% above lower-cost rural markets, while some smaller markets can fall below broad national retail estimates. Promotions and contractor accounts can outweigh those geographic differences.
Painter labor often ranges from about $25-$75 per hour, depending on location and experience, but many contractors price by project rather than hourly. A crew’s work may take 1-2 days for a straightforward room and longer for extensive repairs, furniture protection, or exterior access. Ask whether the quote includes wall repairs, primer, cleanup, and a second coat.
Discounts and gallon-size purchases lower paint-only totals
Store sales, contractor accounts, and quoted project pricing can reduce the per-gallon charge, though discounts and eligibility vary. Buying five gallons may simplify a large project and help keep color consistent, but it is not automatically cheaper per gallon; compare the actual container prices and avoid buying more than the job needs.
For a 1,000-square-foot paintable area receiving two coats, a smooth surface may require roughly six gallons at 350 square feet per gallon per coat. At $75-$115 per gallon, the paint budget would be about $450-$690 before tax. Use the calculated quantity to compare quotes, not just the advertised price of one gallon.
What to confirm before accepting a Duration quote
Request a written estimate listing the Duration product, interior or exterior use, finish, color, gallon quantity, and price per gallon. For contractor work, ask for separate labor and material totals and clarify whether primer, patching, caulking, masking, cleanup, and disposal are included.
Check whether the estimate assumes one coat or two, and confirm how extra paint or unexpected surface repairs are billed. If the total seems high, compare another quote using the same paint specification and scope. A like-for-like estimate reveals whether the difference comes from the paint price, labor, or preparation.
