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.
Exterior door replacement cost: include the complete opening scope
An exterior door replacement cost estimate begins with the actual opening and selected complete unit, not just a door catalogue price. Record dimensions, wall thickness, swing, threshold and the surrounding finishes. Ask the responsible specialist to assess opening condition and the specified weather-closure scope. A replacement into a suitable opening is different from resizing it or correcting concealed damage.
Keep door-unit supply, removal, fitting, specified sealing or flashing work, interior trim and exterior finish repair identifiable. List included locks and handles, and check what arrives within the supplier package to avoid duplication. Describe the finished handoff on both sides of the opening. Changes to security features or specialist assemblies require a confirmed product scope rather than a generic door allowance.
When comparing exterior door quotes, give each bidder the same product and opening schedule. Access and observed condition need assessment before a firm price. Ask how temporary closure, disposal and discoveries behind the existing trim are covered, and keep resulting frame or wall repair separate from routine replacement. A bare unit price is not an installed replacement cost.
A separate worked planning example
Independent illustrative arithmetic: one hypothetical selected unit at £650.00, fitting at £220.00, removal at £60.00 and defined finish allowance at £90.00 sum to £1,020.00. Concealed-opening repair is outside this arithmetic. These hypothetical inputs are not market rates and do not replace the amounts in the linked PDF.
Cost and scope questions
Does an exterior door replacement quote include the threshold?
Ask for the selected unit and threshold specification, and the assessed weather-closure and finish scope. A catalogue door price may not include the complete opening work.
Can all door replacement work use the same rate?
Only if products, openings, condition and finishing scope are comparable. Resizing and concealed damage should be separately assessed.
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.
