THE SHORT ANSWER
Estimate cladding repair from the damaged area, matching product, access and condition of backing. Show purchased material apart from repaired wall area and state how concealed damage will be handled.
Use this fictional 5.6 sq m localised lap-cladding repair in Manchester to plan the estimate. The agreed work is: Replace 5.6 sq m of visibly damaged accessible lap cladding on a single-storey wall after confirming suitable backing. Include removal, 6.7 sq m material allowance, fitting, limited finishing trim allowance, waste handling and clean-up. No structural or concealed moisture repair. The matching exterior cladding repair 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. Mark the repair boundary
Photograph and measure the courses to be removed, including start and stop points. A localised repair should not imply full-wall replacement.
2. Check product compatibility
Match profile, thickness and finish as closely as the actual supplier options allow. The 6.7 sq m allowance is a fictional purchase quantity for 5.6 sq m installed.
3. Inspect backing when opened
The base price assumes sound supporting material. If removal reveals damage, document it and obtain a revised scope before further repair.
4. Define finish expectations
Explain whether priming, painting and colour blending are included. A new cladding piece may not visually match weathered adjacent material without separate finishing work.
Calculate the measured lines
The PDF uses 6 separate items. For example, Damaged cladding removal is 5.6 sq m × £38.80 = £217.28; Replacement cladding allowance is 6.7 sq m × £94.70 = £634.49. 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 6 rounded line amounts gives £1,971.29. 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 and photograph repair courses.
- Identify matching cladding product.
- Confirm access and backing assumption.
- State finish and concealed-repair process.
Outside the base scope: No structural repair, concealed moisture remediation, full-wall replacement, finish painting or multi-storey access.
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
Why is material area larger than repaired area?
The example allows for cuts and stock sizes. Verify the actual purchase quantity against the selected product.
Will new cladding match existing colour?
Do not assume a perfect match. Describe the product and any finishing work included before the customer accepts the scope.
