Homeowners type this question into search engines thousands of times every month, and the answers they get back are often frustratingly vague. At CountBricks, we believe price transparency starts with solid data, not guesswork. Below we unpack the real numbers, explain the variables that matter, and show you how our AI platform delivers a pin-point estimate in minutes.
Every cost guide seems to offer a different “average,” ranging anywhere from $250 to $1,000. Why the spread? Location. Labor rates in a high-cost market like San Jose, CA can be 35 % higher than the national median. Paint brands, accessibility, and seasonal demand widen the gap even more. CountBricks taps into live material pricing and crowd-sourced labor data from vetted residential contractors, so you see an accurate local range instead of a generic national figure.
• Door size and material: Steel, aluminum, wood, or composite each require different prep and primer.
• Surface condition: Peeling paint, rust, or deep wood grain add extra prep hours.
• Color change intensity: Going from dark to light or vice versa can double coating layers.
• Finish level: Standard exterior acrylic costs less than premium elastomeric or specialty marine-grade.
• Access and obstructions: Tight driveways or built-in basketball hoops slow production time.
• Local labor burden: Wage, insurance, and permitting factors fluctuate zip-code by zip-code.
1. Basic repaint, single 8 × 7 ft steel door, minimal prep: $325 – $475
2. Mid-grade repaint, double 16 × 7 ft aluminum door, moderate prep: $550 – $825
3. Premium refinish, real wood carriage door, extensive sanding and stain: $1,000 – $1,600
Remember these are working ranges. The CountBricks estimating engine calculates within ±3 % of final invoice by factoring the exact door specs, your city’s labor rate, and live paint shelf prices.
Our software pings multiple regional suppliers every 15 minutes. If a gallon of exterior acrylic drops by $2 overnight, your estimate reflects the savings instantly.
CountBricks tracks historical production rates from hundreds of garage door projects in its database. The AI adjusts for variables like spray vs roll application, door panel count, and weather delays to forecast crew hours with near-perfect accuracy.

• Material cost DIY: $70 – $180 for primer, paint, rollers, drop cloths.
• Equipment rental: $40 – $60 per day for an airless sprayer if you want the factory finish look.
• Time investment: 6 – 10 weekend hours, longer if sanding or dealing with oil-based coatings.
• Risk factors: Inconsistent sheen, lap marks, overspray on vehicles, and voided warranties on insulated doors.
CountBricks clients often discover the DIY path saves less than $150 after rentals and hazard disposal fees. A licensed pro backed by a CountBricks-generated scope delivers a durable finish and a clear paper trail for future resale disclosures.
• Schedule in shoulder seasons (early spring or late fall) when painters aren’t slammed with full exterior repaints.
• Stick to factory-matching colors to reduce the number of coats.
• Combine the project with other small paint tasks—CountBricks bundles mobilization fees.
• Allow overnight drying time between primer and topcoat; rushing forces a third coat.
• Request low-VOC formulas; they cure faster and reduce callbacks.

CountBricks removes the mystery from garage door painting and every other residential construction project you tackle.

A homeowner in Willow Glen asked, “How much does it cost to paint a garage door that’s starting to fade?” Using the CountBricks voice app, they confirmed a 16 × 7 ft aluminum panel door with mild oxidation. Within three minutes the platform returned:
• Surface area: 252 sq ft including trim
• Prep tasks: Light power-wash, spot prime bare metal
• Materials: Two gallons premium acrylic, one quart rust-inhibiting primer
• Labor: 6.4 crew hours at the San Jose residential rate
