Repair or Replace? How to Decide on a Garage Door
Most people ask this question when something has just broken, which is the worst moment to weigh it up. So here’s the honest version, before you need it.
Almost always a repair
A broken spring. It’s the most common failure there is and it says nothing about the condition of the door itself. Springs are wear parts with a rated lifespan; replacing them is routine.
A dead opener. The opener is a separate machine bolted to the ceiling. A stripped gear, a burnt board or a failed capacitor is a repair, and even a full opener replacement costs a fraction of a new door.
Frayed cables, worn rollers, loose hinges. All wear parts, all cheap next to a door, all fixable in a single visit.
One dented panel. On most sectional doors a single panel can be replaced without touching the rest, provided the model is still available.
Usually a replacement
Rust through the bottom section. Once steel has rusted through from the inside, the panel has lost its structure. Patching it buys a season, no more — and in Calgary the bottom panel is the one sitting in slush and road salt all winter.
Multiple cracked or delaminated panels. Wood doors that have started to delaminate keep going. Fixing one panel on a door in that state usually means being back for the next one.
A door that’s been repaired three times in two years. At some point the running total exceeds the price of a new insulated door, and you’ve been paying for a door you don’t want anyway.
No insulation on an attached garage. This one is a choice rather than a failure. If the garage shares a wall with the house, an uninsulated door is the largest hole in your building envelope, and the comfort difference after replacing it is the thing customers mention most.
The rough rule we use
If the repair costs more than about half of a new door, and the door is over fifteen years old, replacing usually works out better. Under either of those thresholds, repair.
What we won’t do is quote you a new door because a spring broke. Ask any company that does to explain exactly which parts are beyond repair — a straight answer is easy to give when it’s true.
When you do replace
Ask about R-value rather than just thickness, check the warranty covers the hardware and not only the panels, and get the opener assessed at the same time — an old opener paired with a new, heavier insulated door is the next thing to fail.
