I've reviewed more door frame quotes in the past six years than most contractors see in a career. That's not a flex—it's math. We spend roughly $180,000 a year on building materials, and when I say roughly, I do not mean guessed. I mean documented in our cost tracking system, line by line, since 2019.
This checklist is how I actually buy door frames and French door units. It's not theory. It's the exact process I use when comparing quotes. Five steps. The order matters.
Most procurement mistakes happen before the quote arrives, not after. If you email three suppliers and say "need 40 frames," you'll get three quotes for three different products. The only way to compare honestly is to codify every opening first.
This is where a door code system comes in. Every opening gets a code. I use a simple convention:
Each code carries the frame material, size, jamb depth, and swing direction. A full door schedule turns "we need doors" into a spec sheet any supplier can price without a million clarification calls. When we send a coded schedule and the supplier quotes it without questions, that's a green flag. When they ask what F21 means, it means we built the code wrong—or they're not used to working from schedules, which is its own problem.
The old belief that "you have to walk the site with a supplier before they can quote frames" comes from an era before standardized door schedules and digital takeoffs. Today, suppliers that can't work from a coded schedule will slow you down on every order. We built our coding system in 2021 and have used it on 200+ orders since. Maybe 220; I'd have to check the ledger. Our quote errors dropped by about 70%.
This is the step that burned me once and taught me permanently.
In Q2 2024, I compared quotes for 120 steel door frames. A millwork distributor quoted $42 per frame. An online metal supplier quoted $36. The spreadsheet said the online option—about 14% cheaper on the unit. My gut said something was off, mainly because their delivery date came with the word "approximately" attached.
The numbers said go with the online supplier. My gut said stick with the distributor. I went with my gut and asked the online supplier for a fully delivered quote. Here's what came back:
Total delivered cost per frame: $44.80. The distributor's all-in price: $43.10. The lower unit price was actually 4% more expensive once the fine print was included. That's a $204 swing on one order—or rather, $240 when you count the extra time we spent reconciling the invoice.
Since then, our procurement policy requires an all-in quote before any P.O.: base price, freight, unloading, fuel surcharge. No exceptions. Because a "cheap" French door unit that needs a $90 jamb extension kit and a $120 delivery surcharge isn't a cheap unit at all.
Pricing referenced from our Q2 2024 procurement records. Verify current rates with your supplier—frame prices and freight fees change regularly.
The uncomfortable truth in building materials: a supplier who claims to be great at everything usually isn't great at anything. I'd rather work with a specialist who knows their limits than a generalist who overpromises.
We buy French door units in volume from Peacemaker. But when I asked about a custom steel entry frame, their rep said, "This isn't our strength—here's who does it better." Then he sent a competitor's contact. That honesty earned our core door frame business for everything else. The vendor who tells you when to go elsewhere is the vendor you trust when he says he can handle it.
I have mixed feelings about one-stop-shop suppliers. On one hand, consolidating simplifies purchasing. On the other, every product line a supplier adds can dilute the ones they started with. For standard interior frames, a general supplier works fine. For exterior French door units exposed to rain and wind, specialists are worth the premium.
Liquid glass—a nano-coating marketed for water and scratch resistance—gets added to a lot of door frame quotes automatically. On exterior frames in coastal or high-humidity environments, it can be genuinely useful. On interior frames in a dry warehouse, it's a line item you shouldn't be paying for.
How to turn off liquid glass? Simple. Request itemized quotes, and explicitly write: "No coatings unless specified in drawings." The first time I did this, a supplier's quote dropped 12%. They'd rolled the coating into every frame without a word. I didn't find out until I asked them to break down the price.
Look, I'm not saying liquid glass is a scam. It's a legitimate coating. We order it on exterior units. But it should be your choice, not a default that pads the supplier's margin. Keep an eye on two other culprits in the same neighborhood: "shop drawing preparation fees" and "warranty administration charges." If it's not itemized, it's not free.
In 2023, 11% of our steel frames arrived with transit damage. That was a bad year, and it forced a supplier change. We got it down to about 4% in 2024. But 4% is still 4%. The question isn't whether you'll get damaged frames occasionally. It's what the replacement process actually costs.
Before you place an order, confirm:
Part of me wants to consolidate to one supplier for simplicity. Another part knows why we keep a backup: one vendor's "5 to 7 business day" replacement took 19 days during a freight surge in Q3 2024. Peacemaker's standard replacement runs 5 business days, which is why they're our primary. (Should mention: we order spares in pairs—two frames for any job over 30 openings. It's insurance you can return.)
It sounds basic, but 30% of our first delivery on the last big job would have been wrong if we hadn't checked the labels. Verify swing direction and hinge prep against your door schedule before approving payment. A French door with the wrong swing is a $400 paperweight.
A $350 French door that needs a $90 jamb extension isn't a $350 door. Wall thickness varies. Suppliers can't guess it. Put the jamb depth in the spec and confirm it on the P.O. "It's not our standard jamb" usually means "we don't want to adjust their production line."
Cheap foam weatherstripping on exterior frames starts peeling within 18 months. EPDM or silicone costs a couple dollars more per frame. Buying 100 exterior frames? The cheap option saves you $200 and generates $2,000 in callbacks. Every time.
The most frustrating part of this business: the same mistakes recur despite clear communication. You'd think written specs would prevent misunderstandings, but interpretation varies wildly. The door schedule solves most of that—which is exactly why it's Step 1.
Is this more work upfront? Yes. Does it feel like overkill for a "simple" door frame order? Sometimes. But I've watched a $200 savings on a quote turn into $1,200 in rework when the wrong door code gated a French door delivery. The true cost of a door frame isn't the price on the quote—it's what the frame makes you spend after it arrives.
That's it. Five steps. Done.

The door codes in this article are a procurement scheduling system, and Peacemaker is a building materials brand. If it's door frames you need—welcome. You're in the right place.
