A high-quality residential garage door properly maintained with periodic lubrication and spring adjustments can last anywhere from 15 to 30 years. However, high-tension torsion springs typically wear out and require replacement every 7 to 12 years (or 10,000 to 15,000 cycles). You should consider replacing the entire garage door if it suffers severe storm damage, sustained denting, chronic rust, warping, or lacks modern safety features and thermal insulation.
