How Much Does It Cost to Paint an 1800 Sq Ft House in 2026
If you’re wondering how much does it cost to paint an 1800 sq ft house in 2026, the short answer depends on inside vs. outside: a professional interior paint job for an 1,800 sq ft home typically runs $3,000–$6,500, while the exterior runs $2,500–$5,500. Doing both together usually lands at $5,500–$12,000. Interior pricing runs $1.50–$3.50 per square foot of floor area; exterior runs $1.50–$5.00 per square foot of paintable surface. Labor is 60–70% of either total.
Quick-answer table (typical 2026 professional cost for an 1,800 sq ft house):
| Project | Typical cost | Per sq ft basis |
|---|---|---|
| Interior, walls only | $2,700–$4,500 | $1.50–$2.50 / floor sq ft |
| Interior, walls + ceilings | $3,500–$5,500 | $2.00–$3.00 / floor sq ft |
| Interior, full (walls, ceilings, trim, doors) | $4,500–$7,500 | $2.50–$4.00 / floor sq ft |
| Exterior, single-story | $2,500–$4,500 | $1.50–$3.00 / paintable sq ft |
| Exterior, two-story | $3,500–$5,500 | $2.50–$4.00 / paintable sq ft |
| Interior + exterior together | $5,500–$12,000 | Bundle discount 5–15% typical |
An 1,800 sq ft home is the classic American 3-bedroom — big enough that DIY takes real weekends, small enough that a pro crew finishes fast. This guide covers interior and exterior pricing separately so you can budget whichever project you’re actually planning.
How Much Does It Cost to Paint an 1800 Sq Ft House Interior
Interior painting for an 1,800 sq ft home breaks down by scope. Walls-only is the budget refresh; full trim and doors is the “like new” package:
| Interior scope (1,800 sq ft home) | Typical pro cost | Timeline |
|---|---|---|
| Walls only, same color | $2,700–$4,500 | 2–3 days |
| Walls, bold color change | $3,200–$5,500 | 3–4 days |
| Walls + ceilings | $3,500–$5,500 | 3–4 days |
| Walls + ceilings + trim and doors | $4,500–$7,500 | 4–6 days |
| Add cabinet painting (kitchen) | +$1,200–$3,000 | +2–3 days |
Trim and doors are hand-brush work — slow, fiddly, and the reason the full package costs nearly double the walls-only price. Ceilings add material (flat white, more gallons) and neck-straining labor. If your budget is tight, paint walls now and schedule trim later; walls deliver 80% of the visual change.
Room-by-room, expect $300–$800 per room in an 1,800 sq ft home — bedrooms at the low end, living rooms and kitchens (more trim, more cutting-in) at the high end. Bathrooms run $200–$500 but need moisture-resistant paint.
Exterior Painting Cost for an 1800 Sq Ft House
Exterior pricing for an 1,800 sq ft home follows siding type and stories:
| Siding type (1,800 sq ft home) | Single-story | Two-story |
|---|---|---|
| Vinyl / aluminum | $2,500–$4,000 | $3,500–$5,000 |
| Wood siding | $3,000–$5,000 | $4,000–$6,500 |
| Fiber cement | $3,000–$4,500 | $4,000–$6,000 |
| Stucco | $3,000–$5,000 | $4,000–$6,500 |
| Brick | $3,500–$6,000 | $4,500–$7,500 |
An 1,800 sq ft single-story ranch has roughly 1,200–1,600 sq ft of paintable surface; a two-story of the same floor area has 1,600–2,200. Prep condition moves the number as much as siding — peeling wood siding on a two-story can push past $6,500, while sound vinyl on a ranch can come in under $3,000.

If you’re refreshing the whole exterior and the windows need replacing too, see our window replacement cost for 20 windows guide.
Homes built before 1978 need EPA lead-safe work practices when old paint is disturbed — inside or out — which adds containment and specialized cleanup to the bid.
Paint Quality Tiers: What the Gallons Cost
Paint choice matters less than prep, but it still moves the material bill:
| Paint tier | Per gallon | 1,800 sq ft interior (walls) | Notes |
|---|---|---|---|
| Contractor-grade | $25–$35 | $300–$500 | Thin, needs extra coats; fine for rentals |
| Mid-tier 100% acrylic | $40–$55 | $500–$800 | The sweet spot for most homes |
| Premium (top lines) | $60–$80 | $800–$1,200 | Better coverage, washability, fade resistance |
| Specialty (cabinet, enamel) | $50–$90 | — | Trim, doors, and cabinets only |
An 1,800 sq ft interior typically needs 10–15 gallons for two coats on walls; add 5–8 gallons for ceilings. Exterior needs 12–20 gallons depending on siding. The J.D. Power 2026 paint satisfaction study consistently finds coverage and durability — not price — drive satisfaction, which matches contractor advice: buy the mid-tier at minimum.
Cost Drivers for an 1800 Sq Ft Paint Job
| Driver | Effect on cost | Notes |
|---|---|---|
| Color change | +10–25% | Dark-to-light needs extra coats, inside and out |
| Prep condition | ±$1,500+ | Patching, scraping, caulking are labor-heavy |
| Ceilings and trim scope | +40–80% over walls-only | Hand-brush detail work |
| Vaulted / tall ceilings | +15–30% | Scaffolding and slower production |
| Number of stories (exterior) | +30–60% | Ladder and lift work |
| Regional labor rates | ±25% | Metro and coastal markets higher |
| Occupied vs. empty (interior) | +10–15% | Furniture moving and masking |
An empty house paints faster and cheaper — if you’re between move-out and move-in, schedule painting then. For interior work, compare with our interior painting cost per square foot breakdown and the size-specific guides for 1,500 and 2,000 sq ft interiors.
DIY vs Hiring a Pro
| Factor | DIY | Professional |
|---|---|---|
| Interior cost (1,800 sq ft) | $500–$1,200 materials | $3,000–$6,500 |
| Exterior cost (1,800 sq ft) | $700–$1,600 materials | $2,500–$5,500 |
| Time (interior) | 3–5 weekends | 3–5 days |
| Time (exterior) | 2–4 weekends | 3–5 days |
| Skill needed | Moderate indoors; high on ladders | Their daily work |
| Finish quality | Good with patience; cutting-in is the hard part | Crisp lines, even coverage |
| Risk | Time sink; ladder falls outdoors | Licensed, insured |
| Best for | Interior walls, single-story exteriors | Two-story exteriors, full trim packages |
Interior DIY is the best value in home improvement — $500–$1,200 in paint and supplies vs. $3,000–$6,500 for a crew, and the skill ceiling is patience, not talent. Exterior DIY makes sense on a single-story; on a two-story, ladder work plus prep volume usually justifies the pro.
Money-Saving Tips
- DIY the interior, hire the exterior. The classic split saves $2,500–$5,000 while keeping the risky ladder work professional.
- Paint before moving in. An empty 1,800 sq ft house paints 10–15% cheaper — no furniture moving, no masking marathons.
- Limit the color palette. Every additional color means more cutting-in and more partial gallons; two or three colors max keeps labor down.
- Buy paint during holiday sales. Memorial Day, Labor Day, and Black Friday sales routinely cut premium paint 30–40%.
- Do your own masking and moving. Crews bill $50–$75 per hour for prep you can do the night before.
- Bundle interior + exterior. One mobilization, one crew — expect a 5–15% bundle discount versus separate contracts.
- Skip the premium on low-traffic rooms. Mid-tier paint in bedrooms and premium washable paint in kitchens, halls, and kids’ rooms targets the money where it matters.

For an 1,800 sq ft home they’re close: interior $3,000–$6,500 vs. exterior $2,500–$5,500 professionally. Interiors cost more when trim, ceilings, and doors are included; exteriors cost more on two-story homes or peeling siding. Interior DIY saves far more in absolute dollars because there’s no ladder or weather risk.
The Bottom Line
Painting an 1800 sq ft house costs $3,000–$6,500 for the interior and $2,500–$5,500 for the exterior in 2026 — $5,500–$12,000 for both together. Interior DIY is the single best money-saver in the project ($500–$1,200 vs. $3,000–$6,500 pro), while two-story exteriors are where professional crews earn their fee. Get itemized quotes, compare prep scopes before totals, and time the purchase around a paint sale — the paint itself is the smallest line on the invoice, but buying it 30% off still matters.
Prices are typical 2026 US ranges gathered from contractor pricing data and industry sources; your actual cost depends on interior vs. exterior scope, prep condition, paint quality, number of stories, regional labor rates, and the contractor’s pricing. Always get at least three written, itemized quotes from licensed, insured painters.
