You have two quotes on the table. One is higher. Neither document tells you whether the two companies are proposing the same piece of work, and that is the problem this page is built to solve.
What this page does, and what it refuses to do
This page gives you a method for turning two or three unstructured door quotes into a single sheet you can read across, dimension by dimension, so that a difference in price sits next to a difference in what is being supplied.
It will not tell you whether a price is fair. It will not tell you which contractor to hire, rank anyone, name a winner, or pass judgement on anyone’s honesty. We publish no price ranges on this page at all — those live in our entry door cost guide and patio door cost guide, and they belong there.
What you get instead is a vocabulary. By the end you should be able to say, for each part of the job, whether your quotes agree, disagree, are silent, or are describing work that cannot sensibly be compared at all. That last outcome is a legitimate result, and reaching it honestly is worth more than a verdict we would have to invent.
Why two quotes for “the same” door describe different jobs
Three things move independently of each other, and a quote can pin down one of them while leaving the other two unsaid.
Scope. One company may plan to fit a new door into the frame already in your wall. Another may plan to take the frame, the sill and the trim out and start from the rough opening. Both can be the right call. They are not the same job, they do not take the same time, and the finished wall does not look the same afterwards.
Product. Two doors of the same width, in the same material, from the same manufacturer, can sit in different product lines with different glass packages and different hardware. The quote may name the line, or may say “fiberglass entry door” and leave it there.
Inclusions. Trim, painting, disposal, hardware, permit fees, patching the wall afterwards. Each is either in the price, excluded in writing, or unmentioned. Unmentioned is its own category and it is the one that generates the phone call three weeks later.
We are deliberately not telling you how often each of these explains a given gap between two numbers. We have no source for that, and a made-up proportion would be worse than no proportion.
How to read a per-dimension verdict
The method rests on four verdicts. Use them precisely; the whole thing falls apart if unknown and different blur together.
| Verdict | Use it when | What you do next |
|---|---|---|
| SAME | The quotes state the same thing for this dimension — including when both state the same documented exclusion. If both say painting is not included, that is agreement. | Nothing. This row is settled. |
| DIFFERENT | Both quotes say something here, and what they say differs. A known difference is DIFFERENT, not UNKNOWN, and it is not automatically a problem. | Decide whether the difference matters to you, and what it is worth. |
| UNKNOWN | The evidence is missing from one or both quotes. Silence is not a specification. | Ask. UNKNOWN is a question, never an assumption and never a fault finding. |
| NOT COMPARABLE | The two quotes describe structurally incompatible scope here, so no like-for-like reading exists — one prices a sound opening and the other prices a repair, say. Always write down why. | Decide which job you actually want, then ask both companies to quote that job. |
The distinction worth repeating: UNKNOWN is about absent evidence. DIFFERENT is about present and divergent evidence. NOT COMPARABLE is about incompatible scope, and a NOT COMPARABLE cell with no stated reason is not usable.
Three quotes, not two
A verdict is a statement about a pair, so a three-column sheet has no single verdict per row. Do this instead:
- Nominate a reference quote — usually the most fully specified one, not the cheapest. Write down why you chose it.
- Score the others against the reference, row by row. Each cell holds a pairwise verdict: B against A, C against A.
- Where B and C differ from A in different ways, note the B-against-C verdict for that row as well. Those comparisons surface differences that a reference row can hide.
- Never average a row. “Two SAME and one DIFFERENT” is not a result.
The thirteen dimensions
1. Product and series
Brand, product line or series, and any model identifier. “Fiberglass entry door” is a category, not a product. If the quote does not name the line, that is an UNKNOWN worth resolving first, because several of the rows below depend on it.
2. Configuration
Panel count, swing or slide direction, sidelights, transom, and the actual opening size. A single door with two sidelights and a door of the same overall width are different orders.
3. Glass
The glass package name, the lite pattern, coatings, whether the glass is laminated or impact-rated, and grilles. A marketing name for a glass package is not a performance rating — if energy numbers matter to you, our guide to ENERGY STAR door requirements and NFRC labels covers where the certified figures for your exact configuration actually come from.
4. Installation method — two separate questions
This is the row people get wrong, because the trade uses overlapping words. Extract two independent facts:
- What unit is being supplied? A slab on its own, or a door already hung in a frame with jambs and header.
- What is being removed? Whether the existing frame, sill, interior casing and exterior trim come out, or stay.
These do not determine each other. A door supplied already hung in a frame is routinely installed in an opening where the old frame is taken out — Pella states both that its front doors come pre-hung and that in a replacement “the existing door, frame and trim must be removed first” (Pella, updated 8/17/2026). So two quotes can both say “prehung” and describe different amounts of work. Our guide to slab, prehung and full-frame replacement works through both questions properly.
5. Opening condition
What the quote assumes it will find, and what happens if it finds something else. The sentence to look for is the one covering rot or damage discovered once the old unit is out: is there an allowance, an hourly rate, or nothing at all? A quote that is silent here is not cheaper, it is less finished.
6. Trim and finish
Exterior brickmould or casing, interior casing, and paint or stain — including who does it and when. Factory finish, site finish and “primed only” are three different outcomes.
7. Threshold and sill
Sill type, whether it has adjustment in it, and whether a low-profile option is quoted. One caution: “low-profile sill”, “flush sill” or “reduced trip hazard” is marketing language, not an accessibility rating. If accessibility is a requirement for your household, ask for a documented rise and slope rather than accepting the phrase.
8. Flashing and sill pan
Whether a sill pan and flashing are included, and how the flashing is lapped. Check whether the quote says either way: once the trim is back on, it is not something you can confirm by looking.
9. Haul-away
Removal and disposal of the old unit and the debris. Easy to state up front, irritating to discover later.
10. Hardware
Lockset, handle set, multipoint hardware, hinges, finish, and who supplies what. Lock architecture is worth settling before the order goes in, because a multipoint lock needs the jamb prepared for its keepers. If you have a particular smart lock in mind, confirm compatibility with the gearbox and trim for that specific door before you commit.
11. Permit and inspection
Whether a permit is being pulled, by whom, in whose name, and whether fees are in the price. Requirements are local, and they genuinely differ — see the section below.
12. Warranty
Not “does it have a warranty”, but which document, carrying what date, issued by whom, and what it says about labour.
Two things worth knowing before you compare warranties at all. First, a warranty document’s date and scope decide whether comparing two of them is honest; a document from several years ago may or may not govern a purchase made today, and a document may or may not state which purchases it applies to — some of the ones we read do, and some do not. Second, where a PDF is hosted does not establish who issues it or which sales channel it covers. A door warranty found on a retailer’s website may be the manufacturer’s own document, naming the manufacturer as warrantor and routing claims to the manufacturer. What matters is the issuer named in the text, the product and geographic scope, the manufacture-date or purchase-date applicability, and whether the text itself limits the channel. Our guide to what a door warranty covers goes through this with the documents cited.
13. Unknown and missing items
The register of what is simply absent. This row exists because some products genuinely have no publicly readable documentation, and because “I could not find this” is information you want written down rather than forgotten.
The comparison sheet
Thirteen rows, a reference column, and one or two comparison columns. Each comparison column holds a pairwise verdict per row, plus a short note. There is deliberately no cost column: the moment a number enters the sheet, people start reading the verdicts as a justification for the number instead of as a description of the work.

Items to check explicitly
Not a list of things anyone is hiding — a list of things a quote may include, exclude in writing, or simply not mention. Check each against every quote you hold:
- Haul-away and disposal of the old unit
- Exterior brickmould or trim, which may be priced per linear foot
- Interior casing
- Paint or stain, and who applies it
- Hardware and lockset
- Threshold
- Flashing and sill pan
- Weatherstrip
- Drywall or stucco patching
- Permit and inspection fees
- Interior protection and cleanup
Permits: local, and genuinely different
There is no national rule here in either direction, and anyone who tells you there is has not looked. A few jurisdictions, in their own words:
- Chicago, IL — a permit covers replacement “in existing openings”, and “This permit does not authorize any increase or decrease in the size of existing wall or roof openings.” (City of Chicago)
- Minneapolis, MN — a permit is required both to “replace entry door in existing wall opening” and to “install entry door in new or enlarged wall opening”. The document reflects the 2020 Minnesota Residential Code and states it is not a complete set of requirements. (City of Minneapolis)
- Bloomington, MN — “A permit is required for ALL window replacements and exterior door replacements, including the door from the garage to the house.” (City of Bloomington, 2023)
- Litchfield Park, AZ — exempt “if the existing window and door opening width and corresponding window/door header does not change.” (City of Litchfield Park)
- Miami-Dade County, FL — for doors without glass, “The current Notice of Acceptance (NOA) of each door used” is required, along with “The required positive and negative pressures”. This is Miami-Dade County specifically, not Florida generally. (Miami-Dade County)
Check your own building department. The pattern across these examples is that the size of the opening, and whether the header is altered, tends to matter more than the door itself — but that is a pattern, not a rule, and your jurisdiction is the only one that governs your job.
If a quote raises egress requirements, ask which adopted code text it is working from. Requirements are set by the edition your jurisdiction has adopted, and they differ. North Carolina’s 2018 Residential Code provides that “The egress door shall be side-hinged, and shall provide a clear width of not less than 32 inches (813 mm) where measured between the face of the door and the stop, with the door open 90 degrees (1.57 rad). The clear height of the door opening shall be not less than 78 inches (1981 mm)…” (NC Office of State Fire Marshal). Massachusetts, under 780 CMR 51.00, Tenth Edition Residential, Chapter 3, goes further: “A primary and secondary egress door shall be provided for each dwelling unit.” — primary 32 inches clear, secondary side-hinged 28 inches with sliding permitted, 78-inch clear height (Commonwealth of Massachusetts). Two states, two different answers, both current where they apply.
If a quote advertises a federal tax credit
A 2026 quote that advertises a federal tax credit for exterior doors is describing something that no longer applies: the credit is not allowed for property placed in service after 31 December 2025 (Public Law 119-21, per the IRS). Ask what the line refers to. For a door placed in service on or before that date, eligibility was conditional rather than automatic — the door had to meet the applicable requirement, and for 2025 the IRS also requires a qualified manufacturer’s QMID reported on the return — so do not read an older installation as automatically qualifying. Our standards guide covers where this stands.
How to send the questions back
Every UNKNOWN row becomes one short, neutral question. You are a buyer clarifying scope, not building a case against anyone, and the tone matters because you may well end up working with this person.
A workable message: “Thanks — I’m comparing two quotes and want to make sure I’m reading them the same way. Could you confirm, for this job: whether the existing frame is being removed or kept; whether a sill pan and flashing are included; whether haul-away is in the price; and which warranty document comes with the door?”
Send the same questions to everyone, in the same words. Asymmetric questions produce asymmetric answers, and then you are comparing your own enquiry rather than their work.
Putting it together: what your sheet is telling you
The sheet does not produce a winner. It produces one of three states.
Comparable. No NOT COMPARABLE rows, and the UNKNOWN rows have been resolved by asking. Only in this state does a difference in price tell you something about price.
Comparable after questions. UNKNOWN rows remain, but they are answerable. Your next step is the questions, not the decision.
Not comparable as written. One or more rows describe incompatible scope. The honest conclusion is that these are quotes for different jobs — and reaching that conclusion is a real result, not a failure of the exercise. Decide which job you want, then ask for quotes against it.
Say it plainly to yourself before you sign: a lower price with different specification or different scope is not a better offer. It may still be the offer you want. That is a different sentence.
What homeowners report
Three accounts from public forum threads, read on 26 September 2026. Each is one homeowner’s self-report. None is verified, none is an average, and none should be used as a benchmark for your own job — they are here because they illustrate how wide a spread can be while everyone involved believes they are quoting the same thing.
- A homeowner in the Tampa Bay area of Florida reported four quotes for one impact window-and-door scope at $42,000, $57,000, $82,000 and $91,000, with bronze frames reported above $110,000 (Houzz thread, approx. 2017).
- A homeowner decomposed a roughly $1,400 entry-door total as around $500 for the door plus around $900 for installation and haul-away — and said they still could not judge it (Houzz thread, location not stated).
- A homeowner in Phoenix, Arizona described a four-door package quoted roughly $1,000 below a big-box quote, and described paying the premium for recourse if something went wrong (Houzz thread).
What this page does not cover
Price ranges and what drives them belong to the entry door cost guide and the patio door cost guide. The scope decision itself — what unit to buy and how much of the opening to remove — is worked through in slab, prehung and full-frame. Warranty structure and what transfers to the next owner is its own guide. Energy criteria, labels and how to verify a quoted door’s certified numbers are in the standards guide. Impact and structural ratings are a separate subject and are not covered here yet.
