THE ESTIMATING ANSWER
Estimate fire door closer replacement by measuring the defined three existing rated door leaves, separating product allowances from labour and setting out the work sequence and exclusions. This fictional Brighton example uses 7 itemised lines totalling £2,328.00; its exact quantities and rates appear in the paired app PDF.
The worked job is three existing rated door leaves in Brighton. The written scope is: Replace closers on three existing rated door leaves with selected compatible units and verify closing action after fitting. Its matching itemised example shows how that description becomes quantities, allowances and a PDF. These figures are fictional inputs for learning the method, so check the real site, specification and supplier or subcontractor costs before quoting.
1. Define the measured job
Replace closers on three existing rated door leaves with selected compatible units and verify closing action after fitting. Record door rating documentation, leaf size, mounting pattern and hold-open features. Record the measurements and existing condition in the estimate before turning quantities into line items. The scope should make clear why this is a separate project from a broader renovation or maintenance quote.
Measure for this job: Record door rating documentation, leaf size, mounting pattern and hold-open features. Record the measured basis next to the relevant cost lines, since a room count, fitted length and purchased product quantity may each use a different unit.
2. Build a product and labour schedule
Identify closer model and mounting plates separately from adjustment labour. This example has 7 distinct lines, including door condition and specification, old closer removal, closer unit allowance. Use actual supplier prices and labour inputs for a customer job; the displayed amounts are fictional document inputs.
Choose before pricing: Identify closer model and mounting plates separately from adjustment labour. Keep a named allowance when the selection is open, and replace it once the actual product and delivery terms are known.
3. Sequence the work and handoffs
Check current door condition and local requirements with a qualified installer before removal. Show which task depends on access, a selected product or another trade. If that dependency is still open, label the price preliminary and identify the information needed before a firm quote.
Plan the handoffs: Check current door condition and local requirements with a qualified installer before removal. State which stage needs access or inspection before the next can begin, especially if a concealed condition might stop the work.
4. Set a change boundary
A warped leaf or damaged frame prevents a simple closer-only fix. The example excludes door leaf replacement, fire certification or access-control rewiring. Record the discovery, agree the revised work and update the estimate before adding it to the job.
Change trigger: A warped leaf or damaged frame prevents a simple closer-only fix. If this happens, write down the revised quantity and responsibility before adding an item to the customer estimate.
Worked project calculation
The paired PDF has 7 cost lines. For example, Old closer removal is 3 each × £68.00 = £204.00; Closer unit allowance is 3 each × £236.00 = £708.00. Each amount is the stated quantity multiplied by its unit rate. Recheck whether a line describes installed work, a material purchase allowance or a distinct visit before changing its quantity.
| Work item | Quantity | Unit rate | Amount |
|---|---|---|---|
| Door condition and specification | 1 lump sum | £184.00 | £184.00 |
| Old closer removal | 3 each | £68.00 | £204.00 |
| Closer unit allowance | 3 each | £236.00 | £708.00 |
| Mounting plate allowance | 3 each | £60.00 | £180.00 |
| Closer fitting | 3 each | £216.00 | £648.00 |
| Closing-force adjustment | 3 each | £92.00 | £276.00 |
| Documentation and clean-up | 1 lump sum | £128.00 | £128.00 |
| Illustrative total | £2,328.00 | ||
Adding the 7 exact line amounts gives £2,328.00. The PDF uses a 0% tax input and no markup solely to display this arithmetic. Decide the appropriate tax, overhead and profit treatment for an actual job; the fictional rates are not local averages or price recommendations.
Scope and price boundaries
Replace closers on three existing rated door leaves with selected compatible units and verify closing action after fitting.
Outside this example: No door leaf replacement, fire certification or access-control rewiring.
The role in this brief is commercial contractor. Confirm who supplies the selected products, makes the site safe, removes waste and signs off the work. Where opening up reveals a different condition, document it and issue a revised scope and price rather than silently extending the base estimate. Also check access, drying or curing time, and the client handoff described in the work sequence.
