What does a French door cost in Phoenix?

What moves yours is the thing a French door has that other doors do not: two operating panels that have to meet, seal and lock against each other, in an opening that is rarely as square as it looks.

Every published French door figure, side by side

Start with the last two rows, because they are the same publisher.

Angi's dedicated French door page says $2,000–$5,000. Angi's front-door installation page prices a French door at $5,800. One site, one month, one product, two incompatible figures, neither page acknowledging the other. That is before anyone has localized anything.

Finding one: Fixr's labor range cannot be reconciled with anything, including Fixr

Two sources publish a labor line for an exterior French door.

Fixr's entire range sits below the midpoint of Angi's. Its ceiling is roughly half of Angi's ceiling, and its floor is $78. There is no version of a two-panel exterior door installation — remove the old unit, set and shim a new frame plumb and square, seal it, hang and adjust two panels so they meet, fit and adjust a multi-point lock, then patch inside and out — that happens for $78 of labor.

Now hold that against Fixr's own headline. Fixr's average French door project is $2,221. If labor tops out at $302, then $1,919 of that average is material and everything else. Fixr's own material discussion does not support a figure like that as a typical case, and Angi's competing material range for the same product starts at $300.

The deeper problem is that Fixr never states what the $2,221 covers. Its French door page carries exactly one table. There is no breakdown by material, no breakdown by door type, no breakdown by size, no breakdown by brand — all of which that publisher provides on other door pages. So a reader cannot tell whether the average is a supply-only figure, an installed figure, an in-swing or out-swing, a 5-foot or an 8-foot unit, or a blend of all of them.

Two published labor ranges for the same job, in the same country, that barely touch at the edges and share no common middle, is not a market variation. It is a scope definition problem, and neither page defines its scope.

Finding two: the "Phoenix" French figure is national data with a multiplier on it

Angi's Phoenix front-door page lists French doors at $570–$5,480 and presents itself as local survey data.

Every figure on that page is the national page's figure multiplied by 0.944. Fourteen rows out of fourteen. The French row is $5,800 national and $5,480 Phoenix — the same ratio as wrought iron, composite wood, steel, fiberglass and the headline average, all of which have nothing in common with each other in material, weight, labor or supply chain.

We lay the full fourteen-row teardown out, along with the same site publishing a Phoenix door repair page two weeks later at a uniform multiplier in the opposite direction, on the Phoenix door replacement cost hub. It is worth reading once, because it is the cleanest evidence in this whole category of what a "local" cost page usually is.

For your purposes here, the short version: the $570 low end of the "Phoenix" French range is not a Phoenix measurement, and no Phoenix installer we could find publishes anything remotely near it for an installed exterior French door.

What actually makes a French door different

This is the part the cost pages skip entirely, and it is where your money goes.

Two operating panels instead of one. A slider has one moving panel riding on rollers in a track, meeting a fixed panel. An entry door has one panel meeting a frame on three sides and a threshold on the fourth. A French door has two panels that have to meet each other in mid-air, along a vertical joint, and stay meeting each other through every hot afternoon and cold night for the life of the door. Everything below follows from that.

Two sets of weatherstripping, plus the joint between the panels. Each panel seals to the frame, and the pair seals to each other — usually through an astragal on the fixed or inactive panel. That is more linear feet of seal than any other residential door type, and the seal at the center joint is the one that tells you immediately whether the install was right. Daylight at the center means the panels are not meeting.

A multi-point lock, not a deadbolt. Most exterior French doors lock at several points up and down the panel rather than at one point in the middle, because a tall panel with nothing but a center latch will bow. Multi-point hardware is a real engineering component with its own adjustment, and it is the piece most likely to be wrong on a cheap install — a multi-point that needs the door lifted or shoved to throw is a door that was hung out of square, not a lock that needs replacing.

In-swing or out-swing, and it is not just a preference. In-swing costs you interior floor space and furniture placement. Out-swing costs you patio clearance and puts the hinges outside, which means the hardware needs non-removable or security-pinned hinges. It also changes how the threshold and the sill pan shed water. Decide this before you shop, because it is not a change you make later.

And more of the price is in getting the install right. A slider that is slightly out of level drags. A French door that is slightly out of square will not latch, will not seal at the center, and will show a tapered gap you cannot unsee. The tolerance is tighter, the adjustment takes longer, and a crew that rushes it produces a door that looks wrong from across the room. That is the real reason French door labor is not a $78 line item.

The single most expensive variable: does the opening change?

Almost no cost page mentions this, and it dwarfs every other decision on the list.

Dropping a French door into an opening built for a French door is one job. Converting an opening from something else is a different job, with framing, header work, stucco patching outside and drywall and trim inside.

One homeowner's report makes the point better than any table: a 6-foot slider converted to a single 36-inch French door came in at $5,600. That is a self-reported, unverified figure from a public thread and it is not Phoenix-specific — but look at what it describes. The opening got narrower, which means new framing, a new header condition, and patching on both faces of the wall. That is a door price plus a carpentry project, and it lands above the top of two of the four national ranges in the table at the top of this page.

Any French door quote you accept should state, in writing, whether the opening is being modified, and what exterior and interior patching is included. If it does not say, that is your first question, and the answer determines whether the rest of the quote means anything.

Glass area, SHGC, and the two numbers to ask for

A French door is mostly glass. In this climate that makes the glazing specification a bigger decision on this door than on almost any other opening in the house.

The federal guidance for hot climates is not ambiguous: "Look for a low solar heat gain coefficient (SHGC)... Low SHGCs reduce heat gain in warm climates."

ENERGY STAR's current specification, Version 7.0 (effective October 2023), sets the bar for a door that is more than half glass at U-factor ≤ 0.28 and SHGC ≤ 0.23 in the hotter zones — South-Central and Southern. A French door is comfortably over the half-glass threshold.

One honest caveat. The v7.0 specification text does not define those climate zones geographically, so we are not going to tell you which zone your address is in. Check it on ENERGY STAR's own climate zone map, not on a manufacturer's summary page — and here is why that distinction is not pedantic. One major manufacturer's published summary of v7.0 states Southern-zone windows at U ≤ 0.40 / SHGC ≤ 0.25 and more-than-half-glass doors at ≤ 0.30 / ≤ 0.25 in all zones. Both of those contradict the actual ENERGY STAR specification. Use energystar.gov itself.

Ask every bidder for the U-factor and SHGC from the NFRC label, in writing, for the exact glass package they are quoting. A bidder who cannot produce both numbers is selling you a door they have not looked up.

There is a second reason glass matters more on this door. Peer-reviewed work on insulated glass units found that "Sunlight is regarded as the most important aging factor on IGUs" because of its thermal and photochemical effects on the edge seal, that edge sealants exhibit "six to eight times more permeability at 60 °C than 20 °C," and that loss of the insulating gas can "increase the U-factor of an IGU up to 32%." The same study found aluminum spacers leaked more gas than non-metallic warm-edge spacers over 70 weeks of testing.

The honest gap: we have no field measurement showing that a Phoenix door's edge seal actually reaches 60 °C. That is a laboratory finding and we are not going to bridge it to your patio with a number nobody has published. What we will say is the structural point — a two-panel glazed door has more glass perimeter, and therefore more edge seal, than a single-panel door of the same width. Ask what spacer is in the unit.

Hardware, and a documented absence

For sliding doors there is a published industry durability bar. AAMA 906-21 cycles sliding door roller assemblies 10,000 times under load at the manufacturer's rated weight, measuring clearance and operating force before and after, across capacities from 75 pounds to more than 600 pounds.

That specification is for rollers. A French door has no rollers. Its wear items are hinges, the multi-point lock mechanism, and the compression seals — and we could not find an equivalent published cycling specification for hinged patio door hardware. That absence is worth knowing when a salesperson tells you a hinge set is "rated" for something. Ask which standard, and ask for the number.

What manufacturers do publish is warranty terms, and those are checkable. ProVia's entry system and patio door warranty, whose doors we install, is a good example of how to read one:

Read those middle three rows again with a French door in mind. The multi-point lock and the weatherstripping — the two components a French door depends on most and has the most of — carry the shortest terms on the card. That is not a criticism of the product; it is clearly written and it is a good warranty. It is a criticism of the phrase "lifetime warranty" as used at kitchen tables.

The warranty also excludes, verbatim, "Warping or failures of the frame and brickmold which are the result of or involve stress caused by localized application of heat, movement of building or building components, or expansion/contraction of building or building components." In this climate, read that clause before you rely on the word lifetime.

And the part nobody volunteers: a manufacturer's warranty does not cover labor. Ask any bidder, us included: which document, which components, how many transfers, and is labor in it.

What a French door quote should itemize

1. In-swing or out-swing, stated
2. Exact opening size, and whether the opening is being modified
3. Manufacturer and product line — the actual series
4. Glass package with NFRC U-factor and SHGC, in writing
5. Spacer type in the insulated glass unit
6. Lock type — multi-point or single-point, and the make
7. Hinge specification, and for an out-swing, whether the hinges are security-pinned
8. Threshold and sill pan, and whether the threshold is adjustable
9. Stucco, drywall and trim repair — included or excluded, explicitly
10. Product warranty and labor warranty separately, with terms

Items 2, 9 and 10 are the ones that catch people. A quote that modifies an opening without mentioning exterior patching either includes it or is about to become a change order.
