Estimate an exterior entry door by the measured opening, selected prehung unit, threshold details and surrounding finish. Keep product, fitting and weather closure visible rather than quoting a bare door price.

THE SHORT ANSWER

Estimate an exterior entry door by the measured opening, selected prehung unit, threshold details and surrounding finish. Keep product, fitting and weather closure visible rather than quoting a bare door price.

The worked project in this guide is one prehung entry door . It uses an original fictional job to explain the estimating decisions, with a matching exterior entry door replacement PDF example (https://quicklyestimates.com/en-us/samples/exterior-door-replacement-estimate/). Replace the example inputs with your measurements, supplier quotes and labor costs.

1. Identify the replacement assembly

Record opening dimensions, swing, sill and hardware selection. A slab-only job differs from this prehung replacement in both product and labor.

2. Inspect the existing opening

The sample assumes suitable framing and adjacent finishes. Hidden deterioration or enlargement requires a separate inspected scope before proceeding.

3. Detail weather and hardware work

List threshold, weatherstrip and handle fitting responsibilities. Clarify which components come with the selected unit so allowances do not duplicate supplier packages.

4. Define finish and disposal

State whether casing, paint, exterior trim and old-door disposal are included. The touch-up allowance here is limited, not a full wall or siding refinish.

A worked exterior entry door replacement calculation

One prehung door allowance × $1,050 = $1,050, and one installation line × $690 = $690. Together they are $1,740; hardware, threshold and trim remain separate.

The complete example contains 7 lines totaling $2,640.00 before any tax or markup. These are deliberately stated example prices, not a survey, regional price recommendation or offer to perform the job.

To set your own selling price, review direct costs and decide how you will cover overhead and profit. For example, adding 20% to a $1,000 cost gives $1,200; it does not produce a 20% gross margin. Use the approach you intend consistently, and avoid adding a second markup to rates that already include it.

Before you send the estimate

- Measure opening, swing and threshold.
- Confirm selected unit and hardware.
- Inspect framing and adjacent finishes.
- Define trim and disposal limits.

Example scope boundary: No opening enlargement, structural repair, siding replacement, full repainting or specialty security system integration.

Review the client name, location, validity date and all calculations. Tax is not included in this example; determine the correct treatment for the actual work rather than copying a sample percentage.

Common questions

Is an exterior door the same scope as an interior door?

No. Threshold and weather closure details need explicit consideration along with the selected assembly and opening.

Does the price include painting?

Only where stated. This example has a trim touch-up allowance but no complete door or wall repaint.
