Repair a garage door when the trouble is in its springs, cables, rollers, hinges or opener, which are wear parts made to be swapped out, and replace it when the panels themselves are giving out or the same door keeps eating repair money year after year. A door that stops working often needs only a repair.
This checklist walks through the calls we make standing in the driveway. If the answer points to a fresh start, new garage door installation covers styles and what the install involves; if one panel is the whole problem, section replacement may be all the door needs.
First, sort the problem into hardware or the door itself
Everything that moves the door is hardware and can be replaced on its own; the sections are the door, and their condition settles most repair-or-replace questions.
| What is wrong | Hardware or door | Usually points to |
|---|---|---|
| Broken torsion or extension spring | Hardware | Repair |
| Frayed lift cable or cracked drum | Hardware | Repair |
| Worn, noisy or cracked rollers and hinges | Hardware | Repair |
| Track bent by a bumper | Hardware | Repair |
| Opener that hums, clicks or strips gears | Hardware | Repair, or a new opener, never a new door |
| Torn bottom seal letting rain in | Hardware | Repair |
| One dented or creased section | Door | Replace that section if it can be matched |
| Rust holes along the lowest section | Door | One section, or the door if rust shows higher up |
| Soft, crumbling wood in rails and stiles | Door | Rebuild or replace, depending on how far it runs |
| Several cracked or bent sections | Door | New door |
Notice how far down the table you go before a new door becomes the obvious answer. Even a door that groans and shudders can run quietly again after its hardware is refreshed.
A ten-question checklist
The ten questions weigh moving parts, damaged sections, rust, rot, squareness, repair history, cost, use, HOA rules and how long you will stay; the more answers that land on the replace side, the stronger the case.
- Is the problem in a moving part? If so, repair it and stop here.
- How many sections are damaged? One can usually be replaced. Two or more on a discontinued model tips the balance toward a new door, since old panels are often impossible to match.
- Is the rust on the surface or through the steel? Surface rust sands, primes and paints. A hole that shows daylight does not.
- Is the wood firm? Probe the bottom rail and the foot of each stile with an awl. Firm wood can be sealed and refinished; soft, stringy fibers mean a rebuild or a new door.
- Is the door still square in its opening? A racked or sagging door leaves wedge-shaped gaps and fights its tracks and seals for the rest of its life.
- How many repairs in the last few years? Fixr’s repair guide suggests thinking about replacement when things keep breaking on and around the door.
- Is the repair creeping toward half the price of a new door? That is our rule of thumb. Past that point, the money buys more as a new door with new hardware, and our price board lists starting prices for both paths.
- Is the garage changing use? A workshop, gym or finished room wants an insulated door that a hollow single-layer door cannot become.
- Does an HOA have a say? Some associations set style and color, so check the rules before ordering a section that only comes close.
- How long will you stay? If you are selling soon, a sound repair and fresh paint may serve the sale just as well; if you are staying, a new door’s quiet and comfort show up every day.
If most answers fall on the repair side, repair. If three or four land on the replace side, ask for both prices before deciding.
Rust and rot: how far is too far
Damage confined to the bottom section is usually a repair; damage that has climbed into the upper sections means the whole door has been soaking up water for years.
Steel doors often rust first along the lowest edge, where the bottom seal holds rainwater against the skin. A blistered bottom section can often be handled by swapping just that section and its seal. When rust also shows at the hinges and edges of the sections above, the door is near the end.
Wood doors often give out first where the bottom rail joins the stiles. Rot in one rail can be removed and the rail rebuilt by a carpenter or a door shop, while rot running up the stiles into several sections can cost as much to rebuild as a new door. The rot repair guide for wood doors goes deeper on that decision.
Builder doors from the 1990s are reaching the question
Census estimates date more Washington County and Clark County housing to the 1990s than any other decade, so many suburban houses there are around 30 years old, and an original door with straight, dry steel is still a strong repair candidate.
Where the original door is still hanging, it has likely had a spring or two replaced and may still run on its first rollers and cables. If the paint has chalked and rust is starting along the bottom, run the checklist above before spending on hardware.
Inner Portland raises a different question. If an older detached garage has an opening that matches no stock door size, a new door has to be built to order, which costs more and takes longer to arrive. On a garage like that, a careful repair, even a section rebuilt by hand, often comes out ahead.
Permits, zoning and HOA rules
Portland treats a same-size swap and a resized opening differently: the first needs no building permit, and the second does.
The city’s permitting bureau, Portland Permitting & Development, puts door replacement in an unchanged opening on its no-permit list and puts new or resized openings on the list that requires one. Oregon’s Building Codes Division draws the same line statewide. Our Portland garage door permit guide covers the details, including merging two single openings into one wide one.
One zoning detail matters if you want a door with glass. On street-facing walls in Portland’s single-dwelling zones, windows in a garage door do not count toward the zoning code’s window standard, though windows in the garage wall do. A windowed door is a style choice, not a way to meet that rule.
In Clark County, ask the city of Vancouver’s permit center or the county before resizing an opening. Wherever you live, homeowners association design rules may govern door style and paint color, so get approval before ordering.
When a new door is worth the money
A new door pays off when it solves problems a repair cannot touch: a failing shell, a garage that needs to hold some warmth, or an opening you are changing anyway.
An insulated steel door is stiffer and quieter than a hollow one and holds a little more warmth in an attached garage. Expect the return in comfort rather than a check in the mail; Energy Trust of Oregon’s list of residential incentives has no category for garage doors.
A new door also resets every wear part at once: springs matched to its weight, new rollers, cables and track, and often a better seal at the slab. If several of those were due anyway, the gap between a big repair and a replacement narrows quickly.
How we help you decide
Send one wide shot of the door taken from the street side and a close-up of the worst damage, and we can usually tell you which side of the line it falls on before anyone visits.
At the door we check the hardware first, because a heavy or noisy door is often a spring or roller problem dressed up as a bad door. When both paths are reasonable, you get both a repair price and a replacement price in one visit, and the decision stays yours.
