Wood and Wood Composite Garage Doors: Species, Upkeep and Weight

Real wood: species and construction

Wood doors are usually a frame-and-panel slab, or a wood cladding applied over an insulated core for better thermal performance.

• Cedar — stable, naturally rot-resistant, takes stain beautifully; the most common premium choice
• Hemlock and fir — economical paint-grade options
• Mahogany and accoya — top-tier stability and rot resistance at the highest price
• Overlay construction — cedar or mahogany face over insulated steel or composite base

Wood composite: the practical alternative

Composite doors use engineered board or fiberboard skins with a molded woodgrain texture over an insulated core. They hold paint extremely well, do not rot or split, resist humidity swings, and weigh far less than solid wood — which means smaller springs and less hardware stress. On a driveway, most people cannot tell an overlay composite carriage door from painted wood.

Maintenance reality in Georgia humidity

This is the part that decides whether a wood door is right for you.

• Inspect the finish annually, especially the bottom rail and the sun-facing side
• Re-stain or repaint every 2 to 4 years; south and west exposures need it sooner
• Keep the bottom seal intact — standing water is what destroys wood doors
• Never pressure-wash a wood door; it drives water into the joints
• Watch for swollen sections that bind in the track after a wet season

Weight, springs and openers

A real-wood double door can exceed 400 lbs. That requires correctly calculated torsion springs (often high-cycle), heavy-duty hinges, 13-ball or steel rollers, and a 3/4 HP or wall-mount opener. Reusing the springs from a lighter steel door is the single most common mistake we find on wood door installations, and it destroys openers.
