What every Plumbing proposal should include
A weak proposal loses jobs even when your price is competitive. Here's what separates proposals that clients sign from ones they ignore.
Exact materials and brands
Specify the water heater brand and model, pipe material (copper, PEX, CPVC), and any fixtures being installed. Clients who've done research — or who've been burned by a cheap water heater before — will ask. Be specific.
Water shutoff and access requirements
Plumbing work often requires shutting off water to the home or a section of the house. State how long water will be off and whether the client needs to do anything in advance — this is the most common source of day-of friction.
Permit requirements (where applicable)
Water heater replacements, sewer line work, and bathroom remodels often require permits. State clearly whether a permit is required, whether it's included in your price, and what the inspection process looks like.
Parts vs labor breakdown
Itemizing parts and labor separately prevents the common client objection of 'why does this cost so much?' When they can see the water heater is $780 and labor is $380, the total makes sense. Bundling it into one number invites skepticism.
Warranty on parts and labor
Manufacturers typically offer 6–12 year warranties on water heaters. Your labor warranty matters too — state it explicitly. Clients choosing between two plumbers with similar prices will often pick the one who puts a 1-year labor guarantee in writing.
What happens if additional problems are found
Old homes hide surprises behind walls — corroded pipes, galvanized supply lines, mold. Your proposal should include language that any additional scope discovered during work will be quoted before proceeding, never done without approval.

Emergency plumbing vs scheduled work: how your proposals should differ
Plumbing is one of the few trades where a significant share of jobs are emergencies — burst pipes, sewage backup, no hot water in winter. Emergency calls are priced differently and need proposals too, but the language and urgency feel different. Here's how to handle both situations in writing.
- For emergency jobs, send the proposal immediately after diagnosing — clients who are panicking will sign fast if you're professional and clear
- Emergency proposals should include a 'work authorized upon signature' clause so you can start immediately without chasing approval
- Note any after-hours or emergency service fees explicitly — clients expect them but resent surprises
- For scheduled non-emergency jobs, include a preferred start date and estimated completion time — it sets expectations and makes scheduling discussions easier
- For sewer line jobs where video inspection is a prerequisite, break that into a separate mini-proposal — it builds trust before the big number lands
- Follow-up after emergency jobs is critical: send a review request 24–48 hours later when the relief is still fresh. Propofy automates this for you.
Frequently asked questions
Does a water heater replacement require a permit?
In most U.S. jurisdictions, yes — a water heater replacement requires a mechanical or plumbing permit and inspection. Requirements vary by city and county. State clearly in your proposal whether the permit is included in your price, who pulls it, and what the inspection process looks like for the homeowner.
Should I include parts and labor separately in a plumbing proposal?
Yes, always. Itemized proposals are more trusted by clients and easier to compare. When a client sees '$780 for a Rheem 50-gal water heater + $380 labor + $75 disposal = $1,235 total,' the total is easy to accept. A single '$1,235' number invites the question 'what am I paying for?'
How do I handle additional problems found during a plumbing job?
Include a written clause in your proposal: any additional scope discovered during work will be quoted before proceeding. Never do work outside the agreed scope without written or at minimum verbal approval. For text approval, follow up with a quick written confirmation after the fact.
How far in advance should I send a plumbing proposal?
The same day as the estimate, always. Homeowners comparing multiple plumbers will sign with whoever responds fastest with the most professional proposal. If you visit on Monday and send the proposal on Wednesday, you've already lost to the competitor who sent one that evening.
Can I use a plumbing proposal template for commercial jobs?
Yes. Propofy works for both residential and commercial plumbing proposals. Commercial jobs typically require more detail — scope broken out by phase or system, payment schedules, lien waiver language. Propofy lets you add custom sections and terms to any proposal for these situations.
