Updated September 28, 2026 by Chris Horton. Planning analysis, not an appraisal of your contractor. How we estimate costs
For homeowners holding a written door replacement quote from one contractor, any brand. In five short steps it sets what you asked for against what the paper actually prices, names every line the quote leaves unstated, and gives you the questions to send back before you sign. It does not tell you whether the price is fair. Nothing you type is stored.
Have the written quote in front of you. The tool needs the door type and, if you want the optional range context, the total and the number of door openings. Everything else is read straight off the paperwork.
If a line is not on the paper, choose Not specified or leave it unticked. Each gap becomes a question for your contractor rather than a guess by us. It reads one quote at a time, it does not rate the contractor, and it does not name a fair price for your house.
Step 1 of 5 · The job you asked for
The job you asked for
Start with what you requested, not what came back. The next steps read the quote.
What the quote supplies
Read these off the paper. Do not fill in what you assume is included.
Removal and installation
This is where two door quotes usually stop describing the same job.
Warranty and paperwork
Tick only what the quote actually states in writing.
What this quote describes
Each line compares what you asked for against what the paper prices. Same means the quote prices what you asked for. Different means it prices something else. Unknown means the paper does not say. Not comparable means the line changes the job enough that comparing this total against another quote is meaningless until it is resolved.
What the quote does not state
Questions to send back before you sign

What this tool does, and what it does not
It can help you
- See whether the quote prices the job you actually asked for.
- Separate the door itself from the frame, the opening and the installation.
- Name every scope line the paperwork leaves unstated.
- Put the total against a published planning range for that door type.
- Go back to the contractor with specific written questions.
It cannot tell you
- Whether the price is fair, high or a bargain.
- Whether the contractor will do the work well.
- What is behind the trim until the old unit comes out.
- Which contractor to hire.
- What labor costs in your particular market.
