Aluminum Garages

You’ve searched for aluminum garage prices before. All you found were vague ‘starting from’ numbers that told you nothing about what you’d actually pay once delivery and installation got added on top.

Then a quote finally lands, and it’s a mess — add-ons tacked on, delivery fees buried in the fine print, installation costs nobody mentioned in the original conversation. That gamble can cost you thousands you never planned to spend in the first place, all because nobody was straight with you upfront.

We sell aluminum garages with the full cost spelled out up front, no hidden fees, and free nationwide delivery and professional installation standard on every single quote we give you. Call us at (866) 941-4072 or schedule a free consultation for a real number on your project.

Aluminum garages typically range from $3,800 to $28,000+ depending on size, customization options, and features — with delivery and installation included in those prices.

A 12×20 aluminum garage (240 square feet) starts around $3,800–$5,200 for a basic setup with a regular roof style, one garage door, and standard 14-gauge aluminum panels. Perfect for single-vehicle storage or keeping your lawn equipment out of the weather.

Step up to a 20×25 aluminum garage (500 square feet) and you’re looking at $7,500–$10,200. Two vehicles fit comfortably here, and you’ll still have room for a small workshop area or storage shelving along the walls.

A 20×30 aluminum garage (600 square feet) runs $8,900–$12,500. That extra length matters — it gives you space for two vehicles plus a dedicated work area, or one vehicle with serious storage and project room.

Going big? A 30×40 aluminum garage (1,200 square feet) ranges from $18,000–$28,000+ based on your customization choices. We’re talking three to four vehicles, full workshop setups, or combination vehicle-and-equipment storage for small business operations.

Every price we quote includes professional delivery anywhere in the continental United States and complete installation by our experienced crews. Your base price covers the aluminum frame and panels, roof system, one standard walk-in door, one garage door of your choice, all hardware and fasteners, and anchoring to your prepared foundation.

Here’s something most people don’t expect: we also include free engineered drawings stamped for your location’s wind and snow load requirements. That’s documentation you’ll need for permit applications. Most competitors charge $200–$500 for those drawings. We build that cost into our transparent pricing from day one.

Aluminum garage pricing averages $15–$23 per square foot for standard configurations — roughly 15–25% higher than comparable steel garages. That premium buys you aluminum’s superior corrosion resistance and lighter weight, making it the obvious pick for coastal environments and high-humidity climates where steel structures break down faster.

Five primary factors drive your final aluminum garage price: roof style, aluminum gauge thickness, door types and quantities, additional openings like windows, and color choices.

Regular roof style (rounded roof with horizontal panels) is our most economical option, included in base pricing. The rounded design handles water and light snow well — a solid choice for moderate climates.

Boxed eave roof style adds $200–$800 depending on size. You get horizontal roof panels with an A-frame look that improves water runoff and gives your garage a more traditional appearance.

Vertical roof style is our premium option, adding $400–$1,500+ to your project. Vertical panels run from peak to eave, so rain, snow, and debris slide off far more efficiently. Honestly? If your area gets more than 20 inches of annual snowfall or your building codes mandate specific snow load ratings, don’t skip this upgrade.

Standard 14-gauge aluminum panels handle most residential applications beautifully, delivering solid durability at base pricing. They resist denting from normal impacts and withstand wind speeds up to 140 mph when properly installed.

Upgrading to 12-gauge aluminum adds roughly $800–$2,200 depending on garage size. You’re getting 20% more material thickness, which means better dent resistance and stronger overall structure. Our recommendation: go 12-gauge for commercial use, areas with severe weather, or coastal locations within three miles of saltwater.

Your base price includes one standard 36-inch walk-in door and one garage door. Additional garage doors run $650–$1,200 each depending on size. Upgrading to insulated garage doors adds $400–$800 per door — and the temperature control improvement is significant.

Windows range from $85–$175 each depending on size. Popular accessories include:

• Extra walk-in doors: $350–$500 each
• Lean-to attachments: $1,200–$3,500 depending on size
• Insulation packages: $1.50–$2.50 per square foot
• Wainscot (contrasting lower wall panels): $300–$900
• Gutters and downspouts: $3–$5 per linear foot

Yes — our free delivery and installation covers all 50 states with no hidden charges for the vast majority of locations. The price we quote includes transporting all materials to your property and complete professional installation by our certified crews.

Southeast region sees the fastest turnaround — typically 3–6 weeks from manufacturing to installation for standard orders.

Northeast and Mid-Atlantic generally run 4–7 weeks from order to installation.

Midwest states average 4–8 weeks total.

Southwest region falls in the 5–8 week range.

West Coast and Mountain states are our longest delivery routes at 6–10 weeks.

Professional installation means our crews handle everything. We unload all materials, build the complete aluminum frame, install every panel and trim piece, hang all doors, and anchor the structure to your prepared foundation.

Most installations wrap up in 1–2 days depending on size and complexity. And we haul away all packaging materials and construction debris — your property stays clean.

Extremely remote locations — typically more than 50 miles from paved roads or requiring ferry access — may see modest delivery surcharges of $200–$500. We flag these situations during the quoting process, so surprise charges simply don’t happen.

Choose aluminum when corrosion resistance outweighs budget concerns — especially in coastal areas, high-humidity climates, or regions with heavy road salt. Go with steel when maximum strength and cost-effectiveness matter more, particularly in dry climates.

Aluminum’s natural corrosion resistance is its biggest edge over steel. It forms a protective oxide layer when exposed to air, preventing rust even in harsh environments. Aluminum structures in coastal areas maintain structural integrity 2–3 times longer than galvanized steel under identical conditions.

Steel garages, on the other hand, deliver superior strength-to-weight ratios and better dent resistance. A 14-gauge steel panel withstands impacts roughly 30% better than an equivalent aluminum panel.

The maintenance gap is where things get interesting. Aluminum garages need periodic washing to remove dirt and salt buildup. That’s about it. Steel garages demand constant vigilance — every paint chip or scratch that exposes bare metal to moisture becomes a rust problem waiting to happen.

Steel garages cost 15–25% less than comparable aluminum structures. For a 20×30 garage, you might pay $7,200–$9,800 for steel versus $8,900–$12,500 for aluminum. But over a 20-year lifespan, aluminum’s lower maintenance needs and longer service life frequently offset that initial price premium.

Coastal regions (within 10 miles of ocean): Aluminum, strongly recommended. Salt air eats through steel fast.

High-humidity areas (Southeast, Gulf Coast, Pacific Northwest): Aluminum is preferred, though quality galvanized steel with proper coating can still work.

Northern states with heavy road salt use: Aluminum has clear advantages if your garage sits near frequently salted roads.

Dry inland climates (Southwest, Great Plains, Mountain states): Steel performs excellently here at lower cost.

Your aluminum garage requires a level, stable foundation that prevents settling and provides secure anchoring points — typically a concrete slab, gravel pad, or asphalt surface. Foundation costs range from $1,800 to $7,500+ depending on size and type.

Concrete slab foundations give you the most durable base for your aluminum garage. A 4-inch thick slab runs approximately $6–$12 per square foot installed. For a 20×30 garage (600 square feet), expect $3,600–$7,200 for professional concrete work.

Concrete delivers a perfectly level surface, excellent anchor holding power, a clean floor for working, and zero ongoing maintenance.

Gravel pad foundations are the most budget-friendly option at $2–$4 per square foot. A 20×30 gravel pad typically costs $1,200–$2,400. With proper preparation, gravel drains well and anchors solidly — a great fit for straightforward vehicle storage.

Asphalt foundations split the difference at $3–$7 per square foot. You get a relatively smooth, clean surface without the full cost of concrete.

How long do aluminum garages last? Aluminum garages typically last 30–40+ years with minimal maintenance, especially in coastal and high-humidity environments. Their corrosion resistance significantly extends lifespan compared to steel structures in harsh climates.

Do I need a building permit for my aluminum garage? Most counties require building permits for permanent structures. We provide free engineered drawings stamped for your location’s requirements to simplify the permit application process.

Can I customize my aluminum garage after installation? Yes, you can add windows, doors, insulation, and accessories after installation — though it’s more cost-effective to include customizations in your original order.

What maintenance does an aluminum garage require? Very little. Periodic washing to remove dirt and debris, annual anchor bolt checks, and door operation inspections. No painting or rust treatment needed.

How do I prepare my site for delivery? Make sure your foundation is level, cured (for concrete), and accessible to our delivery trucks. Clear the area of obstacles and verify property boundaries before installation day.
