Painting siding costs $1.50 to $4.00 per square foot for professional work, putting a typical 2,000 sq ft home at $3,000 to $8,000 depending on the siding material. That’s roughly one-quarter to one-third the price of tearing everything off and starting with new siding. But vinyl, aluminum, and wood each demand a different prep sequence and often a completely different paint chemistry. Use the wrong product on vinyl and you’ll warp panels. The bonding primer on aluminum isn’t optional: skip it and the paint bubbles off within two seasons.
Cost by Siding Material
Your siding type sets the baseline price more than square footage or story count. Vinyl lands at the low end because intact panels go straight to paint with no primer required. Aluminum costs more due to the specialty bonding primer and a full prep sequence vinyl skips entirely. Wood tops the range because scraping, sanding, and spot-priming bare areas can eat a large share of total labor before a roller ever touches the wall.
| Siding Material | Cost Per Sq Ft | 2,000 Sq Ft Home | Key Cost Driver |
|---|---|---|---|
| Vinyl | $1.50–$2.75 | $3,000–$5,500 | Minimal prep; no primer on sound surfaces |
| Aluminum | $1.75–$3.00 | $3,500–$6,000 | Bonding primer required; light sanding |
| Wood (lap) | $2.00–$4.00 | $4,000–$8,000 | Scraping, sanding, filling, spot-priming |
Vinyl’s low cost assumes sound panels without heavy chalking. If your vinyl is so chalked that a hand swipe leaves thick white residue, the crew needs to pressure wash at 1,500 PSI and let it dry 48 hours before painting. That adds $0.20–$0.50/sq ft and two days to the timeline.
Across all three materials, labor accounts for 70–85% of total project cost, and paint itself is the smaller line item: a 2,000 sq ft home needs only 10–15 gallons at $50–$90/gallon for two coats. That gap between material and labor cost is widest on wood.
Wood costs the most to paint because the labor premium comes from prep time, not roller speed. A crew on a wood-sided home spends most of its labor hours on prep alone: scraping peeling sections, sanding edges so old paint feathers into bare wood, filling nail holes and cracks with exterior wood filler, and spot-priming every exposed section with an oil-based or shellac primer. Skip any of those steps and the fresh coat peels within a year.
The Vinyl Color Rule
Standard exterior paint on vinyl works fine with one restriction: the new color must be the same shade as the original or lighter. Paint vinyl darker than its factory color with conventional paint and you create a heat trap. Dark pigments absorb more solar radiation, raising surface temperature 20–30°F above what the panel was engineered to handle. The vinyl expands past its designed range and warps permanently — buckling and rippling until panels pull away from fasteners. Warped panels can’t be flattened back; they have to be replaced at $5–$12 per square foot.
Two manufacturers have engineered around this limitation. Sherwin-Williams VinylSafe colors use pigments that reflect infrared radiation, limiting heat buildup even in darker shades. The VinylSafe palette includes about 100 colors, and the formulation works with SW Emerald, Duration, Resilience, and SuperPaint product lines. Benjamin Moore Aura Exterior also supports vinyl-safe colors and has a lower application temperature threshold of 35°F — useful if you’re painting in early spring or late fall.
VinylSafe-compatible paints cost the same as their standard counterparts because the difference is in pigment chemistry, not price tier. If you’re using a paint without vinyl-safe certification, stick to colors with a light reflective value (LRV) of 55 or higher — your paint retailer can check LRV for any swatch.
Aluminum Siding: The Primer That Makes or Breaks It
Painting aluminum siding fails more often from bad primer selection than from bad paint. Aluminum costs $1.75–$3.00 per square foot to paint professionally, and most of that premium over vinyl goes toward the primer and extra prep step. The oxide layer on aluminum is chemically different from wood or vinyl — standard latex primer sits on top of it without bonding, and the paint slides off within one or two heating and cooling cycles.
A self-etching primer solves this. It contains phosphoric acid that reacts with the aluminum oxide, creating microscopic pits that anchor the primer into the metal surface. The zinc pigment in most self-etching formulas adds corrosion resistance on top of adhesion. Budget $20–$50 per gallon for self-etching primer, and expect coverage of 200–300 sq ft per gallon, lower than paint because the primer needs to lay down a thicker chemical film.
Skipping any step in this sequence is where aluminum jobs go wrong. Light sand with 80–120 grit to knock down chalking and rough the surface. Clean with a degreasing solution or TSP substitute. Rinse thoroughly and let dry 24–48 hours. Apply self-etching primer to bare or heavily oxidized sections. Then two coats of 100% acrylic latex paint. A flat or low-luster finish hides the dents and imperfections that aluminum siding accumulates over decades better than satin or semi-gloss.
Paint vs. Replace: When Painting Stops Making Sense
A single paint cycle runs one-quarter to one-third of a full replacement. But paint doesn’t last forever, and the math shifts depending on how many repaint cycles you’re signing up for.
| Scenario | Cost | Lifespan |
|---|---|---|
| Paint vinyl siding (one cycle) | $3,000–$5,500 | 5–10 years |
| Paint aluminum siding (one cycle) | $3,500–$6,000 | 5–10 years |
| Paint wood siding (one cycle) | $4,000–$8,000 | 3–7 years |
| Replace with vinyl siding | $7,000–$18,000 | 20–40 years |
A homeowner staying five more years should paint every time. The $3,000–$5,500 paint job on vinyl covers the entire remaining ownership period. Replacement at $7,000–$18,000 recoups about 97% at resale, but you’re still spending 2–3× more upfront than a paint job that covers the same five-year window.
At the 15-year mark, the equation flips. Two repaint cycles at $3,000–$5,500 each total $6,000–$11,000 and still leave you needing a third coat before year 20. A third cycle pushes total spending to $9,000–$16,500. Replacement at $7,000–$18,000 covers the full period and beyond with zero maintenance. The break-even typically falls around that third repaint cycle.
On a cost-per-year basis, a $4,000 vinyl paint job lasting 7 years works out to $571/year. A $12,000 vinyl replacement lasting 30 years costs $400/year. The gap widens further when you factor in the time and disruption of scheduling a repaint crew every 7–10 years. The longer you plan to stay, the more replacement wins on annual cost, but only if you can absorb the upfront spend.
Wood siding hits the break-even faster because paint lasts only 3–7 years on wood compared to 5–10 on vinyl or aluminum, so owners in 10-year timeframes may already need two cycles. Climate matters too: a south-facing home in the desert Southwest burns through paint markedly faster than the same house in a milder Pacific Northwest climate, compressing the repaint interval and pushing break-even closer to replacement sooner. How climate compresses repaint intervals and shifts break-even points for each substrate is covered in the paint lifespan guide .
What Drives the Bid Higher
Two-story or taller homes add $1,500–$3,000 for scaffolding or lift rental and slower crew productivity. Above 16 feet, crews need scaffolding ($200–$800/week) or a boom lift ($230–$580/day), and work pace drops noticeably from ground-level production.
Heavy prep on neglected surfaces adds the most variable cost. Peeling paint on wood siding means hours of scraping at $0.50–$1.00/sq ft. Chalky aluminum needs a full sand-and-prime pass. A house that’s been maintained on schedule costs half as much to prep as one ignored for 15 years, and that prep difference alone can swing a bid by $1,000–$3,000.
Multiple paint colors increase masking time. Three or four accent colors noticeably increase labor because every color change requires taping and retaping between coats.
South- and west-facing walls fade noticeably faster than north-facing walls. If only the sun-exposed sides look bad, ask the contractor to repaint two walls instead of four. Inspect the shaded sides under daylight first; mismatched fading can look worse than uniform wear.
Paint cures properly between 50°F and 85°F surface temperature, so contractors discount 10–15% for late-fall and early-spring work to keep crews busy. Seasonal pricing and regional variation are covered in more depth in the general exterior painting cost guide .
DIY: Realistic for Single-Story Vinyl, Risky for Everything Else
Painting vinyl siding on a single-story ranch is a legitimate DIY project. You need a pressure washer ($75–$150/day rental), a paint sprayer ($50–$100/day rental or $150–$400 to buy), and 10–15 gallons of exterior acrylic at $50–$90/gallon. Total materials and rental: $700–$1,800, roughly 65–75% less than hiring a crew.
Speed is where DIY hurts. A professional crew finishes a 2,000 sq ft single-story exterior in 3–5 days. Solo, expect 60–100 hours spread over 2–4 weekends, mostly because masking every window and door takes as long as painting the walls between them. Weather adds another variable: you need at least two consecutive dry days per coat, and an unexpected afternoon thunderstorm can ruin fresh acrylic before it cures. Start on the north side of the house in summer so direct sunlight doesn’t hit the fresh paint before it can set up.
Aluminum and wood siding raise the DIY risk. Aluminum requires the self-etching primer step; misapply it and you won’t know until the paint starts peeling six months later. Wood prep demands more judgment: if scraping exposes soft or spongy wood, stop — rot repair has to happen first, or fresh paint will fail in under a year. Both materials punish mistakes with callbacks that wipe out the savings.
Two-story work of any siding type belongs with professionals. Ladder falls send tens of thousands of people to emergency rooms each year. Spraying paint from a ladder while managing an air hose and maintaining a wet edge is a different skill set than spraying from the ground, and the savings from DIY on a two-story project rarely cover the cost of scaffolding rental anyway.
Getting the Bid Right
Siding painting bids vary wildly, and the variation usually hides in scope, not skill. Ask every contractor these four questions before comparing estimates:
- Prep scope: How many hours are budgeted for washing, scraping, sanding, and priming? A bid that says “prep included” without specifying scope is a bid that will cut corners.
- Paint product by name. “Two coats of Sherwin-Williams Duration, satin finish” is a real spec. “Premium exterior paint” is not. Product name locks in quality; category labels don’t.
- Surfaces included. Walls only, or walls plus trim, soffits, fascia, and shutters? Trim work is often excluded from base bids and adds $800–$2,500 depending on linear footage.
- Primer plan for aluminum. If your home has aluminum siding, confirm the bid specifies bonding or self-etching primer. Any contractor who plans to use standard latex primer on aluminum doesn’t understand the substrate.
Bids on the same house can differ by 40%. Get at least three, walk each contractor through the prep plan on-site, and confirm the warranty covers peeling and adhesion failure for at least two years.
