Plumbing business guide

Plumbing pricing guide

For plumbing work, a reliable process should build a price from labor, material, overhead and target profit. Record location, fault, repair, part, test and client approval, and itemize each service call, labor hour, fixture and material that affects the price.

Separate diagnosis from the approved repair

Record the fixture or system, reported fault, service address and access conditions. A diagnostic visit, a replacement fixture and concealed pipework are different scopes. State whether the visit fee is charged separately, credited against a repair, or included in a package.

Inspect the accessible work before committing to a fixed repair price. Where opening a wall or exposing a buried pipe could change the work, state the assumption and describe how a revised price will be approved. An undefined allowance should not appear to be a guaranteed total.

Worked plumbing price calculation

The figures below are a costing illustration, not local plumbing rates. The loaded labor cost is what the technician costs the business, rather than the hourly rate shown to a customer. Assign overhead using the business’s documented method.

Explain the scope and change process

Specify the repair, included fittings, testing, cleanup and warranty terms. Identify wall or ground restoration, unusual access, permits and disposal when they are outside the price. Check relevant requirements for the actual job rather than assigning a standard fee to every repair.

After completion, compare technician time and purchased parts with the estimate. Record approved extra work separately, credit any deposit once, and show the remaining amount due. Keeping the diagnosis, approval and final repair together makes a disputed invoice easier to review.
