Who This Checklist Is For (and Why You Need It)

If you're tasked with sourcing doors for a commercial project—whether it's a new build, a retrofit, or you're just replacing that dented hollow metal frame in the hallway—you've probably asked yourself: how much does a door cost?

The short answer is: it depends. The long answer is what this checklist is for.

I'm a procurement manager at a mid-sized construction firm. Over the past decade, I've managed an annual budget of roughly $800k specifically for architectural specialties—doors, frames, hardware, expansion joints, the works. I've negotiated with nine different vendors, built cost-tracking spreadsheets that would make an accountant weep with joy, and made just about every mistake you can make when buying doors.

This isn't a theoretical guide. It's a five-step checklist I now run on every door order. If you follow it, you'll catch the hidden costs that eat budgets alive.

Step 1: Define the 'Door' — Specs Are Not Suggestions

You'd think this is obvious. It is not.

I once assumed a "French door" meant the same thing to every vendor. It doesn't. One vendor's French door is a pre-hung unit with tempered glass and a 90-minute fire rating. Another vendor's is a pair of hollow-core slabs with a generic handle. The price difference? About $1,200 per opening.

Your checklist for this step:

• Core material: Hollow metal, wood, fiberglass, or aluminum? Each has a drastically different base cost and maintenance profile.
• Glass: Is it tempered? Insulated? Is it wired glass for fire ratings? A single tempered glass lite can add $150–$400 to a door, depending on size and certification.
• Fire rating: This is the single biggest cost driver. A 20-minute rated door is half the price of a 90-minute rated door in some cases.
• Hardware prep: Are the mortise locks, hinges, and closer prep included? Or will you pay extra per operation?

Here's the trick I learned after getting burned: send the exact same spec sheet to three vendors. You'll be shocked at how different their interpretations are. One will quote a standard door with a cheap hinge. Another will quote a heavy-duty door with continuous hinges. Both will say they quoted the "same" door. They haven't.

Step 2: Frame and Hardware — The 40% Bait-and-Switch

I still kick myself for my first large door order. I had negotiated a great price on the doors themselves. Felt like a hero. Then the invoice arrived for the frames and hardware. It was 40% of the total cost.

I had assumed the frames were included in the door price. They weren't. The frames were a separate line item from a different manufacturer. The hardware—hinges, locks, panic bars, closers—was another line again.

Break it down:

• Door slab: 50-60% of the total.
• Frame: 20-25% of the total. A standard 16-gauge hollow metal frame for a 3×7 opening runs $150–$350 depending on the profile and finish.
• Hardware: 15-20% of the total. A basic mortise lockset is $80–$150. Add a closer ($40–$120), hinges ($20–$50 per pair), and a panic device ($150–$400), and you're suddenly at $500+ per opening in hardware alone.

Now ask your vendor: Is this quote for a complete opening, or just the door?

A complete opening includes the door slab, frame, hinges, lock/latch, closer, and any thresholds or weatherstripping. If they quote only the slab, you're looking at a 40% hidden cost. Every time.

Step 3: Kick Plates and Customization — The 'Minor' Add-Ons That Add Up

This is the step most people skip. And it's the one that'll get you.

In 2023, I audited six years of procurement data. I found that 70% of our budget overruns came from "minor" customizations: kick plates, vision lites, edge treatments, and special finishes.

A stainless steel kick plate on a hollow metal door is $60–$120. That doesn't sound like much. But when you're ordering 50 doors, and each one has a kick plate, you've just added $3,000–$6,000 you probably didn't budget for.

Check for:

• Kick plates: Standard or heavy-duty? Stainless steel, brass, or aluminum? Size?
• Vision lites: A single 10×10 lite with tempered glass adds $100–$250.
• Edge treatments: Square edge vs. beveled edge? Cost difference: $20–$50 per door.
• Custom paint or finish: Off-white is free. A specific RAL color? $50–$150 per door.
• Item 6 on the checklist: Yes, I said this was a five-step checklist. It's actually six steps—I added this one after the audit. Custom finishes are the silent budget killer.

Get every add-on listed in writing before you accept a quote. Ask: "What is the baseline configuration?" Then add on from there.

Step 4: Shipping and Lead Times — The Urgency Tax

In January 2024, I needed 12 tempered glass doors delivered in four weeks for a renovation with a firm deadline. The standard lead time was eight weeks.

I called our usual vendor. They could do five weeks—for an extra 35% rush fee. I called a second vendor. They could do four weeks—for an extra 50% rush fee and no guarantee on the glass certification.

I went with the first vendor. The rush fee was $2,100. Was it worth it? The alternative was missing a $45,000 construction milestone. The penalty for delay was $5,000 per week.

Here's the math:

• Standard shipping: $400–$800 for a pallet of doors (LTL freight).
• Rush shipping (2-week lead): $1,200–$2,400.
• Rush shipping (1-week lead): $2,000–$4,000.
• Cost of missing a deadline: Variable, but often 5–10x the rush fee.

Look, I'm not saying you should always pay for rush delivery. I am saying that when you have a deadline, the cost of uncertainty is higher than the cost of a guaranteed timeline. Budget for it upfront, or negotiate a faster lead time into the contract price.

One thing I learned: always get the lead time in writing as a guaranteed date, not an estimate. "6-8 weeks" is not a commitment. "Arrives by March 15th" is.

Step 5: Verify the 'Total Cost of Ownership' — Not Just the Invoice

This is where the checklist pays for itself.

After tracking 80+ door orders over six years in our cost system, I've learned that the cheapest quote is almost never the cheapest total cost.

Calculate TCO for doors like this:

1. Base price: The quoted price for the complete opening.
2. Shipping: To your site, not to a depot. (I've paid $300 extra for final-mile delivery more than once.)
3. Installation cost: If your contractor is installing, ask if the door quote includes the frame anchors and shims. A five-cent shim shortage can stop an installation crew for a day.
4. Maintenance cost over 10 years: A cheap door with a standard hinge will need adjustment every two years. A heavy-duty door with a welded frame and continuous hinge might last 15 years without a call-back. That's labor savings.
5. Replacement risk: If the door fails a fire inspection, you're not just buying a new door—you're paying for re-inspection, lost occupancy, and potential fines.

I built a simple cost calculator after getting burned on hidden fees twice. It takes about 20 minutes to run a full TCO analysis for an order of 20 doors. That 20 minutes has saved us an average of $4,200 per order.

Common Mistakes (From Someone Who Made All of Them)

• Not sending the same spec to multiple vendors: You're not comparing apples to apples. You're comparing one vendor's interpretation to another's.
• Assuming 'tempered glass' is a single product: It's not. Tempered glass for a fire-rated door is different from tempered for a non-rated door. The certification matters for the price.
• Forgetting that French doors need two frame kits: Yes, I once ordered one frame for a pair of French doors. The second frame was another $400 I hadn't budgeted for.
• Trusting a verbal lead time: I knew I should get written confirmation, but thought 'we've worked together for years.' That was the one time the verbal agreement got forgotten. The doors arrived three weeks late. The penalty? $7,500.

One more thing: if a vendor says "we can match any price," ask them to match the spec, not the price. Two identical-looking doors can have wildly different internals. A door that costs $800 might have a honeycomb core. A door that costs $1,200 might have a mineral core for fire rating. They look the same. They are not the same.

Use this checklist on your next door order. It'll save you money, time, and the headache of explaining a budget overrun to your boss.
