Understanding Garage Door Panel Damage
Garage door panels can become damaged from a variety of causes—vehicle impacts, weather damage, age, or even improper operation. Understanding the type and extent of damage is the first step in determining the best course of action. At Garage Door Canterbury, we've helped thousands of homeowners in Canterbury and surrounding areas assess and repair panel damage.
Common Types of Panel Damage
Dents and Dings Minor dents from basketballs, bikes, or small impacts are common. These often don't affect the door's operation but can impact curb appeal. Our technicians can often repair these without full panel replacement.
Cracks and Breaks More severe damage that may compromise the structural integrity of the panel. Cracked panels should be addressed promptly to prevent further damage. If you notice cracks, contact our repair team immediately.
Rust and Corrosion Steel doors can develop rust, especially in humid climates or after harsh New Hampshire winters. If caught early, rust can be treated; if extensive, panel replacement may be necessary.
Warping Exposure to extreme temperatures or moisture can cause panels to warp, affecting how the door opens and closes. This is particularly common in our region with temperature fluctuations.

- Minor dents that don't affect operation - Surface rust that hasn't penetrated the metal - Small cracks that can be patched - Single damaged section
