Understanding Interior Painting Costs in Delaware
Thinking about repainting your home’s interior? Whether you just moved in, you’re refreshing before selling, or it’s simply time for an update — understanding the cost is key to budgeting smart.

In this guide, we’ll break down everything you need to know about interior painting costs in 2025 — from average price per room to cost per square foot, and what makes one job more expensive than another.
What Affects the Cost of Interior Painting?
Square Footage
The larger the home, the more surface area needs to be prepped and painted — which increases both labor and materials. Even small differences in square footage can add hours of work, especially with open-concept layouts or vaulted spaces
Paint Quality & Finish
Flat paint is the least expensive, but it's not as washable or durable. Mid-tier satin or eggshell finishes offer a good balance of price and performance. If you're opting for premium paints like Benjamin Moore Aura or Sherwin-Williams Emerald, or high-gloss finishes for durability, expect to pay more per gallon — and potentially more for labor due to application complexity.
Wall Condition
Walls that are in good condition need less prep, which saves time and money. But if your walls have cracks, nail holes, bubbling, water stains, or past wallpaper residue, additional prep and priming will raise the overall cost. Prep is often one of the most time-consuming parts of the job.
Numer of Coats Needed
Going from light to dark or vice versa? Drastic color changes often require a tinted primer and multiple coats for full coverage. If the previous paint was low-quality or uneven, you'll need more paint and labor to achieve a smooth, uniform finish.
Ceiling Height
Standard 8-foot ceilings are quick to paint. But taller walls — especially in two-story foyers, stairwells, or great rooms — require ladders, extension poles, or even scaffolding. This adds labor time and sometimes requires extra crew support.
Ceilings, Trim, Accent Walls
Painting walls is typically the base quote — but ceilings, baseboards, crown molding, window trim, interior doors, and accent walls are often priced separately. These detailed areas take longer to prep and cut in cleanly, especially in older homes with decorative features.
