How to measure a plumbing job
Count fixtures (each sink, toilet, tub or shower, hose bib and appliance connection), then estimate pipe runs from the main to each fixture group. For a repipe, note wall and ceiling access and who does the drywall patching. Note the water heater type and the venting changes needed.

Plumbing estimate FAQ
Should drywall repair be included in a repipe estimate?
State clearly whether patching access holes is included and to what finish level (patch only, or patch, texture and paint). It's a top source of disputes on repipes.
How do I price unknown conditions behind walls?
Use an allowance or unit prices for things like replacing corroded drain sections or adding access, and note that hidden conditions found during the work are billed by change order.
What is the best way to determine labor hours for a plumbing job?
The best way to determine labor hours is to break down the job into smaller tasks and estimate the time required for each task based on industry standards and your team's experience. You can also use historical data from similar jobs to refine your estimates.
How do I handle unexpected expenses or changes to the scope of work?
Unexpected expenses or changes to the scope of work should be addressed through a formal change order process, which outlines the additional work, materials, and costs involved. This helps to ensure that both parties are aware of and agree to the changes.
What information should I include in my plumbing estimate to ensure transparency and trust with clients?
Your estimate should include a clear project overview, scope of work, materials list, labor hours and rates, and payment terms and conditions. You should also provide information about your company, including licenses, certifications, and warranties.
