Get paid for what you found
Plumbers run into surprises behind the wall more than most trades. A change order is how the surprise becomes billed work instead of free work.
Pick a reason and the tool words it for you. A concealed pipe condition, like corroded galvanized you could not see. A code requirement. A fixture substitution. Edit it to match what you hit.
Add your cost lines and overhead and profit, and it totals the change. Turn on attachments to reference the photo or the RFI that backs it up, so the approval is easy to give.

Plumbing Change Order Generator questions
Is this really free?
Yes. No email, no signup, and nothing you type leaves your browser.
Can it help me word it?
Yes. Pick a reason template like a concealed pipe condition, a code requirement, or a fixture substitution, then edit it to fit the work.
Can I attach the RFI or a photo reference?
Yes. Turn on the attachments option and list the drawings, RFIs, or photos your change references, one per line.
Can I change the checklist?
Everything is editable: items, sections, order, and printed columns. The starter list is a starting point, not a cage.
