Quick answer
Replacing a single garage door section usually costs $350–$900+ installed, if the model is still made. When the door is old, discontinued or unrated, a full garage door installation often makes more sense.
Bottom sections take the abuse — car bumpers, standing water, salt spray and rot. Replacing one is a sensible repair when the rest of the door is sound and the section is still available.

When one section is enough
- The door is under about 15 years old
- The manufacturer still makes the section in your size and design
- The colour can be matched or the door repainted
- Springs, tracks and the other sections are in good condition
When it is not
Discontinued models, faded finishes that will never match, multiple damaged sections or an unrated door all push toward replacement. Our repair vs replacement guide walks through the decision.
Why section weight matters
A new section can weigh more than the old one, which changes the door's balance. A proper repair includes re-balancing the springs — part of standard garage door repair.
