THE SHORT ANSWER
Estimate tread replacement per step after measuring the staircase and inspecting support. Keep tread product, installation and adjacent riser work separate, with structural repairs outside the base scope.
Use this fictional eight existing stair treads in Exeter to plan the estimate. The agreed work is: Replace eight selected interior stair treads on a suitable existing staircase. Include removal, tread material allowance, fitting, fastening, limited riser touch-up and clean-up. No stringer repair, railing alteration or finish painting. The matching interior stair tread 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. Schedule the steps
Measure each tread and note returns, nosing and any changes in width. Eight steps may not require eight identical pieces.
2. Inspect support
The example assumes suitable stringers and risers. Squeaks, movement or rot should be assessed and priced before presenting a cosmetic replacement as complete.
3. Choose material and finish
List the selected tread product and whether it arrives finished. The sample excludes final painting or staining, so its handoff must be clear.
4. Protect access and define use
Stair work affects circulation through the home. Agree access, disposal and any staged work needed before the estimate is accepted.
Calculate the measured lines
The PDF uses 7 separate items. For example, Existing tread removal is 8 each × £44.00 = £352.00; New tread material allowance is 8 each × £100.00 = £800.00. 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 £2,736.00. 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.

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
Can I price stairs from total run length?
