THE ESTIMATING ANSWER
For one washer standpipe point, start with a defined scope and measurement basis. Measure pipe run, standpipe height, trap location and fall to the existing waste. Show pipe, trap and fittings separately from wall opening and labor. Price the listed tasks separately and state the condition that would require a revision: Insufficient fall or an undersized receiving line requires redesign.
This guide uses one washer standpipe point as a worked, fictional job. Its matching itemized estimate and PDF let you trace the advice to actual document lines. The role considered here is plumbing contractor. Confirm the site conditions, product selections and your own costs before preparing a client quote.
1. Define the measured job
Add one washer drain connection along a short accessible utility-room route to a confirmed suitable waste line. Measure pipe run, standpipe height, trap location and fall to the existing waste. 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.
Measurement basis: Measure pipe run, standpipe height, trap location and fall to the existing waste.
2. Build a product and labor schedule
Show pipe, trap and fittings separately from wall opening and labor. This example has 7 distinct lines, including route and waste survey, local wall access, pipe and trap allowance. Use actual supplier prices and labor inputs for a customer job; the displayed amounts are fictional document inputs.
Selections to confirm: Show pipe, trap and fittings separately from wall opening and labor.
3. Sequence the work and handoffs
Confirm the downstream drain and appliance position before cutting. 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.
Work sequence: Confirm the downstream drain and appliance position before cutting.
4. Set a change boundary
Insufficient fall or an undersized receiving line requires redesign. The example excludes washing machine purchase, new water supply or buried drainage. Record the discovery, agree the revised work and update the estimate before adding it to the job.
If the job changes: Insufficient fall or an undersized receiving line requires redesign.
Worked project calculation
The example line for connection labor is 7 hours × $90.00 = $630.00. This line is one part of the complete 7-item estimate and uses a fictional unit rate.
The paired estimate has 7 separate lines. For this fictional job, multiply each quantity by its unit price and add the line amounts to get $1,690.00. The sample PDF uses these exact values, with tax and markup left at zero so the arithmetic is visible. This total is an illustration, not a regional price or an offer to perform the work.
| Cost line | Quantity | Unit price | Line amount |
|---|---|---|---|
| Route and waste survey | 1 job | $160.00 | $160.00 |
| Local wall access | 1 job | $165.00 | $165.00 |
| Pipe and trap allowance | 1 job | $240.00 | $240.00 |
| Standpipe and support allowance | 1 job | $130.00 | $130.00 |
| Connection labor | 7 hours | $90.00 | $630.00 |
| Flow and leak check | 1 job | $145.00 | $145.00 |
| Wall closure and cleanup | 1 job | $220.00 | $220.00 |
| Illustrative subtotal | $1,690.00 | ||
Scope and pricing boundaries
Add one washer drain connection along a short accessible utility-room route to a confirmed suitable waste line.
Outside this example: No washing machine purchase, new water supply or buried drainage.
Separately identify supplier allowances, labor, subcontracted work and site-specific risk where they apply. Before giving a selling price, decide how your own overhead, profit and any applicable tax will be handled. Do not copy the fictional rates into a real quote without checking your own measurements and supplier or subcontractor figures.
