THE SHORT ANSWER
Estimate an exterior entry door by the measured opening, selected pre-hung unit, threshold details and surrounding finish. Keep product, fitting and weather closure visible rather than quoting a bare door price.
Use this fictional one pre-hung entry door in Norwich to plan the estimate. The agreed work is: Replace one pre-hung exterior entry door in an existing suitable opening. Include door allowance, removal, installation, weatherstrip and threshold allowance, hardware fitting, interior finishing trim touch-up allowance and disposal. Opening enlargement and structural repair excluded. The matching exterior entry door replacement example and PDF shows the same inputs. These quantities and rates are teaching examples; use your own site measurements, product selections, supplier information and labour figures for a customer job.
1. Identify the replacement assembly
Record opening dimensions, swing, sill and hardware selection. A slab-only job differs from this pre-hung replacement in both product and labour.
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 finishing trim and old-door disposal are included. The touch-up allowance here is limited, not a full wall or cladding refinish.
Calculate the measured lines
The PDF uses 7 separate items. For example, Existing door and frame removal is 1 each × £192.00 = £192.00; Pre-hung entry door allowance is 1 each × £840.00 = £840.00. Check that each unit describes the work being priced: area for a surface, metres for a run, and a count or defined lump sum for a discrete task. A material purchase allowance can differ from the installed quantity when product sizes, cuts or layout require it.
Adding the 7 rounded line amounts gives £2,112.00. The example PDF uses a 0% tax input and no markup; those settings do not determine how to price or treat an actual job. Do not copy the rates as a local price guide.
Check the scope before sending
- Measure opening, swing and threshold.
- Confirm selected unit and hardware.
- Inspect framing and adjacent finishes.
- Define finishing trim and disposal limits.
Outside the base scope: No opening enlargement, structural repair, cladding replacement, full repainting or specialty security system integration.
Confirm the site address, selected products, access, quantities, customer details and validity date. If opening the work reveals a different condition, record the change and update the relevant line before asking the customer to approve the revised work. Preview every page of the PDF so the written scope, line amounts and total tell the same story.
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 finishing trim touch-up allowance but no complete door or wall repaint.
