You Find a Bigger Problem After Quoting: Decision Tree

Why this matters

You gave a price, the customer said yes, you started, and now you are staring at a second problem bigger than the one you came for. The corroded run behind the drywall, the failed component next to the one you are replacing, the panel that is not up to carrying the new load. How you route the next few decisions decides whether you get paid, whether the customer trusts you, and in some cases whether the job is safe to leave. This tree is the order of operations for the moment you go from "fixing it" to "wait, what is this."

Safety branch first: is what you found a hazard

Before any pricing or scope thought, ask whether the discovery is dangerous. Gas, live electrical faults, water near power, stored pressure, structural give, a combustion or venting defect.

• If yes: make it safe now. De-energize and verify dead, shut off and relieve pressure, isolate the leak, stop combustion. Then stop work and reassess. A hazard you found is a hazard you must disclose and cannot knowingly leave live, regardless of scope or budget. If the customer refuses the safety fix, red-tag or lock out what you can, document the refusal, and do not certify the system as safe.
• If no: move to the scope question below.

Stop cutting the moment it is confirmed

Once you know the new problem is real and material, put the tools down. Do not keep opening, cutting, or consuming parts on the assumption it will work out. Every minute past the discovery is unbilled work you cannot reverse and pressure you are quietly loading onto a customer who has not agreed to anything.

Is the new problem required to finish, or just nearby

This is the fork that decides everything downstream.

• Required (a blocker): you cannot complete the quoted repair without handling it. The isolation valve is seized so you cannot even get the water off; the mounting surface has failed; the circuit you must tie into is unsafe as-is. The original job cannot finish as written.
• Optional (adjacent): the quoted repair can complete today; the new find is real but separate. An aging water heater beside the leak, a filter due for an upsize, a compressor showing early wear on a job you came to do on the coil.

Sort honestly. Calling an optional find a blocker to justify the add-on is exactly the move that earns a padding accusation.

If it is a blocker

You are re-quoting, not adding on. Present it that way.

1. Show the customer the finding in place, or a clear photo. Point to the tell they can verify themselves.
2. State plainly that the agreed job cannot finish until this is handled, and why.
3. Give the number and the options: fix it and continue, or stop and restore to a safe, non-worse state while they decide.
4. Get a yes before you resume. If they say no, you stop, secure the site, and bill for the work actually done to the agreed point.

If it is optional

Mention it once, cleanly, and keep it separate from today's work.

• Finish what you were hired to do at the price you quoted.
• Flag the find as a recommendation with the reason and the risk of waiting, not a task you have already started.
• Put it in writing so it is on record, then leave the timing to them. No pressure, no assumed permission.

If you are unsure it is even real

Do not present a maybe as a fact. Confirm it with a measurement or a look before you open a scope conversation, the same way you would confirm any diagnosis. A retracted change order costs more trust than the ten minutes it takes to be sure.

Recap

1. Hazard? Make it safe, then reassess; disclose and never leave it knowingly live.
2. Confirmed and material? Stop cutting.
3. Required to finish = blocker = re-quote with a shown finding and a yes before resuming.
4. Nearby but separate = optional = finish the original, recommend the rest in writing.
5. Not sure it is real? Confirm before you say a word about price.
