Key takeaways
- Insulated aluminum garage doors averaged $2,600 installed in RJ Garage Door Service’s 2025 Raleigh data, against $5,800 for solid cedar carriage doors and about $4,700 for engineered wood overlay.
- A 16 x 7 ft wood door weighs about 250 lb, 135 lb more than aluminum, so it needs heavy-duty torsion springs, 3/32-inch cables and a 3/4 HP opener.
- Wood doors need restaining every 2-3 years or repainting every 4-5 years; aluminum needs a quarterly rinse and an annual wax.
- Solid cedar insulates at about R-1 per inch, while foam-filled aluminum and engineered wood with polystyrene backers both reach about R-6.
Aluminum is the low-maintenance, rust-proof and cheaper garage door, and wood is the warmer-looking, heavier door that needs refinishing every few years. The choice comes down to how much upkeep you’ll accept for real grain.
RJ Garage Door Service built this comparison from a decade of its own installation invoices, service logs and thermal scans around Raleigh and the Triangle.
How do aluminum and wood garage doors compare at a glance?
Aluminum and wood garage doors compare on ten points:
| Category | Aluminum | Wood (Solid or Engineered) |
|---|---|---|
| Impact resistance | Dents on hard blows | Dents/chips; hard to repair |
| Panel weight (16 x 7 ft) | About 115 lb | About 250 lb |
| Typical R-value | R-6 (foam-filled) | R-4 to R-6 (solid/engineered) |
| Rust / Rot risk | None | Moderate without upkeep |
| Maintenance | Quarterly rinse; annual wax | Paint or stain every 2-5 yrs |
| Installed price* | $2.6k (avg.) | $5.8k (avg.) |
| Noise level | Lighter; nylon rollers advised | Heavier; naturally quiet |
| Recyclability | Infinite alloy loop | Biodegradable if untreated |
| Hardware needs | Std. torsion + 1/2 HP opener | Heavy-duty torsion + 3/4 HP opener |
| Warranty typical | 20 yrs finish/frame | 5 yrs finish; 10 yrs structure |
*Installed prices are RJ Garage Door Service’s average Raleigh-area pricing for 2025, including removal of the old door and a standard opener hookup.
Which handles dents and impacts better, aluminum or wood?
Aluminum handles impacts slightly better than wood because its dents are shallow and the finish doesn’t crack. Aluminum skins run 0.040 to 0.060 inch thick; they survive taps from lawn equipment but crease when a basketball hits squarely, and the dent stays unless a pro pulls it.
Wood doors, whether solid cedar planks or engineered LVL cores, take light knocks fine. A hard hit can dent the soft fibers, crack the paint or splinter an edge, and that damage usually means sanding, filler and repainting. In a busy driveway, both doors last longer with a “no-ball zone” painted on the pavement.
Which resists rust, rot and moisture better?
Aluminum resists moisture better than wood, because its oxide film stops corrosion and a scratch only dulls the surface. Wood swells and shrinks with humidity, even when kiln-dried, which stresses the joints and the finish.
RJ Garage Door Service has measured seasonal bowing of up to 1/4 inch across a 16-ft wood door, enough to misalign the weather seals. Engineered wood cores warp less but still need regular sealing. Near the coast or where sprinklers hit the door, aluminum takes moisture off the table.
Which insulates better, aluminum or wood?
Foam-filled aluminum and engineered wood insulate about the same, at roughly R-6, and both beat solid wood. Aluminum conducts heat fast, so manufacturers inject polyurethane foam and add thermal breaks in the rails. Solid cedar gives about R-1 per inch, and engineered panels with polystyrene backers reach R-6.
In RJ Garage Door Service’s July FLIR checks of conditioned Raleigh garages, aluminum interiors ran 6 degrees F warmer than solid wood and only 2 degrees F warmer than engineered wood. You’d notice it only if you run HVAC in the garage.
How does door weight affect springs and the opener?
Door weight drives spring size and opener strain, and the 135-lb gap between a 250-lb wood door and a 115-lb aluminum door is large. Wood doors need heavy-duty torsion springs, 3/32-inch cables and a 3/4 HP motor. In RJ Garage Door Service’s ten-year service logs, springs on wood doors needed replacing about three seasons sooner than springs on aluminum doors.
Aluminum works with a 1/2 HP belt drive, starts and stops softly and sends less vibration into bedrooms over the garage.
How much upkeep does each door need?
An aluminum door needs a quarterly hose rinse, a mild soap wash and a coat of wax once a year to delay powder-coat chalking, plus touch-up pen on any scratch that shows bare alloy. A wood door needs an annual wash and a fresh stain every 2-3 years or new paint every 4-5 years.
Skip the wood finish and UV breaks down the lignin, so the boards crack and cup. Each cycle means sanding, masking and drying time.
Which looks better on your home?
Wood looks better on Craftsman and historic homes, and aluminum looks better on modern ones. Clear cedar, mahogany and cypress glow under semi-transparent stain, and small knots add character.
Aluminum suits contemporary minimalism: flush matte panels, anodized bronze frames or full-view glass hybrids. Powder-coat colors run from bold red to satin black, and faux-wood wraps split the difference.
Which is better for the environment?
Neither aluminum nor wood is clearly greener; the answer depends on finishes and recycled content. Aluminum is endlessly recyclable, and the Aluminum Association says recycled aluminum saves 95% of the energy needed to make new aluminum. Wood from FSC-certified forests is renewable and biodegradable if untreated.
Solvent-based stains applied every few years release VOCs, and heavy wood doors cost more fuel to ship.
How much do aluminum and wood doors cost, and which pays back at resale?
An insulated aluminum door costs about $2,600 installed, a solid cedar carriage door about $5,800 and an engineered wood overlay door about $4,700, based on RJ Garage Door Service’s 2025 Raleigh data.
The 2025 Cost vs. Value Report from Zonda Media, as reported by DASMA, ranked garage door replacement first of 28 projects nationally, with a $4,672 average cost and a $12,507 estimated resale value; it doesn’t split results by material. If you plan to sell within five years and don’t live in a period-style neighborhood, aluminum’s lower price recoups faster. In a historic district or a long-term Craftsman home, wood often earns its premium.
Should you choose aluminum or wood?
Choose aluminum if you want rust immunity, lighter hardware, bold colors and minimal upkeep.
Choose wood if real grain and traditional curb appeal are worth refinishing every few years and paying for heavier hardware.
Whichever you pick, RJ Garage Door Service technicians size the springs, calibrate the opener force and seal the weatherstripping so the door runs well for years. Call (919) 438-7447 for a free estimate.
