Quote comparison · Galveston, TX
Hurricane shutter quote comparison calculator
Enter the totals and opening counts from two written quotes. The calculator divides your own numbers into per-opening figures and shows which openings each quote leaves out. It never supplies a price and cannot say which quote is better.

Enter the totals from your own written quotes, in any one currency. The total boxes start at zero on purpose: this page supplies no prices and has no typical figure to suggest. Use the add-on boxes only for amounts a quote or installer states in writing that you must pay separately, never for guesses.
Results below use the example values shown. Turn on JavaScript to change them.
- Quote A with your add-ons

- Quote A per opening covered
- 0.00Average, not a unit price.

- 0.00Your entries added together.
- Quote B per opening covered
- 0.00Average, not a unit price.
- Per-opening difference, B minus A
- 0.00Negative means B is lower per opening.
- Total difference, B minus A
- 0.00Ignores which openings each covers.
- Openings on your list not in quote A

- Openings on your list not in quote B
- 2 openings
- Quote A covers your list. Quote A covers every opening you listed.
- Quote B covers your list. Quote B leaves out openings on your list. Ask why and what leaving them uncovered means.
- Same number of openings. The quotes cover different counts. Do not compare the totals directly; ask each installer to price the same opening list.
Per opening = (quote total + add-ons) ÷ openings covered. Difference = quote B minus quote A. Gaps = openings on your list minus openings covered. Results are in the same units you enter. Per-opening figures hide differences between small windows and wide doors, so use them as a check, not a verdict.
Have your numbers? Get a quote for these openings
Prepare both quotes before you enter numbers
Use one opening list
Give every installer the same list of openings with IDs. Mark which openings each quote includes.
Find the totals as written
Use the total on the written quote, not a verbal figure or an estimate.
Record separate items in writing
If an installer says permits, inspection, wiring, access equipment or repairs are separate, get the amount or the rule in writing. Enter only those figures in the add-on boxes.
Read the checks first
Look at which openings are missing before you read the per-opening figures.
Then compare the non-numbers
Product, mounting, controls, documentation, warranty and schedule can matter more than the arithmetic.
A worked example with made-up round numbers
On phones, each row is shown with its column labels.
| Item | Quote A | Quote B |
|---|---|---|
| Total on the quote (arithmetic only, not prices) | 100 | 120 |
| Openings covered, of 14 on the list | 14 | 12 |
| Per opening covered | 100 ÷ 14 = 7.14 | 120 ÷ 12 = 10.00 |
| Openings left out | 0 | 2 |
| What the numbers say | Lower per opening and covers the whole list. | Higher per opening and leaves 2 openings uncovered. |
When per-opening figures can mislead
| Situation | What to do |
|---|---|
| The quotes cover different numbers of openings | Compare the missing openings first, then price. Do not compare totals. |
| One quote includes wide doors and the other does not | Run the calculator separately for windows and for wide doors, using the line items on each quote. |
| A quote bundles permits or wiring and the other lists them apart | Use the add-on boxes only for written amounts so both sides are on the same basis. |
| A line is an allowance or still to be confirmed | Ask for a written figure or a stated condition before you compare. |
| Different systems on different openings | Compare opening by opening, not by the average. |

Common questions
How do I compare hurricane shutter quotes fairly?
Give each installer the same opening list, then check which openings, products, mounting and extras each quote includes. Only then compare totals. This calculator divides your own totals by the openings covered and flags openings left out.
Is the cheapest hurricane shutter quote the best?
Not necessarily. A lower total can leave out openings, access equipment, wiring or inspections. This calculator cannot rank quotes; it shows which openings each covers so you can ask about the differences.
What should I add to a quote before comparing?
Only amounts the installer states in writing as separate, such as permits, inspection, wiring, access equipment or repairs. Do not add guesses. If an item is unclear, ask for the amount or rule in writing.
Is price per opening a reliable way to compare quotes?
Only as a rough check. A wide patio door and a small window are very different openings, so averages hide differences. Compare like openings, and use the per-opening figure to spot gaps rather than to decide.
Does the quote calculator send my numbers anywhere?
No. It runs in your browser, sends nothing to a server and stores no values. Our project request form is separate and only collects what you choose to submit there.
