What a replacement costs, and when it is the wrong answer
Before the prices, the harder question: does the door actually need replacing? A good share of the doors people ask us to quote for are sound doors with tired hardware, and the difference in cost is about two thousand dollars.
First: three tests
These settle most cases in about a minute, standing in the garage.
- Is the bottom section rusting through from the inside? Look at the inside face of the lowest panel, not the painted outside. Salt and meltwater work from within, and by the time it shows outside the steel is thinner than it looks. Yes means replace.
- Is a damaged panel still manufactured? If a section is dented or creased and the model is discontinued, any repair is a visible mismatch. No means replace.
- Has the door come off the rail more than once? Twice usually means the rail, the brackets or the framing has been compromised. Yes means look seriously at replacement.
If all three are no, what you probably have is a door needing springs, rollers and hinges — roughly $400 to $700 of hardware that will give you years more. Heavy, noisy, slow and groaning are hardware symptoms, not death.
The prices
| Door | Installed | Who it suits |
|---|---|---|
| Single, non-insulated steel | $1,100 – $1,750 | Detached, unheated garages |
| Single, insulated steel | $1,350 – $2,200 | Attached garages, rooms nearby |
| Double, non-insulated | $1,550 – $2,400 | Detached doubles and workshops |
| Double, insulated | $1,850 – $3,100 | Most Johnson County houses |
| Carriage style, insulated | $2,400 – $4,200 | Leawood, Prairie Village, period homes |
| Hardware refresh instead | $400 – $700 | Springs, rollers and hinges on a sound door |
Where the money goes
Insulation is the single biggest price step and the one most worth thinking about. On an attached garage with living space above or beside it, it earns its keep — and the extra rigidity makes the door quieter and better against hail. On a detached, unheated garage, it is buying you quiet and stiffness rather than warmth, and the case is much weaker.
Style is the second. A carriage door with genuine overlay boards costs substantially more than embossed steel that imitates the look, and both cost more than a flush or raised-panel door. This is purely how you want the front of your house to look, which is a legitimate thing to spend money on — just know that is what you are buying.
Windows add $180 to $560 and bring daylight into a space that usually has none. Worth it if the garage is used as a workshop; less so if it is purely for cars.
Things that are not in the headline price
Jamb repair on older garages, low-headroom rail conversions, and a new opener if yours cannot handle the heavier door. All three are legitimate extras — the test of a good quote is whether they were identified before you committed or discovered afterwards.
And one thing worth knowing
A new garage door is one of the more visible changes you can make to the front of a house, which is why it turns up in every list of renovations that hold their value. We would not put a number on that, because resale figures are guesswork dressed up as data. What is true is that it is a large, prominent surface and a tired one is noticed.
Common questions
How do I know it is time?
Rust through the bottom section from the inside, a damaged panel that is no longer made, or a door that has come off the rail more than once. Any of those three points to replacement. Everything else — heavy, loud, slow, groaning — is usually springs, rollers and hinges at a fraction of the cost.
Is insulation worth it?
On an attached garage with heated rooms above or beside it, yes, and the extra rigidity and quiet are real benefits on top. On a detached unheated garage the thermal argument largely disappears and the money is often better spent on a better opener or hardware.
Can I replace just the damaged section?
If it is still manufactured and the rest of the door is sound, often yes, at $320 to $620 for a section. If the door is twenty years old with corrosion starting at the bottom and springs near their cycle count, you are spending a third of a new door to still have an old door.
Will a new door lower my heating bill?
On an attached garage next to heated space, measurably — but only if the seals are right too. A well-insulated panel above a half-inch gap at the slab is losing more through the gap than the panel. Seals are cheap and should be done at the same time.
Does a new door need association approval?
In Leawood and most newer Overland Park and Olathe subdivisions, yes — style, colour and windows usually need signing off first. Get the letter before ordering. Custom colours cannot be returned, and an approved door arriving a week late beats an unapproved one going back.
