One estimate says replace the lateral. Another says line it. A third offers a spot repair and cleaning. The totals are different, but so is the work. Before comparing numbers, compare what each estimate actually covers.
Fill in one column per estimate. Where an estimate is silent on a row, write unknown and ask that contractor before deciding.

Common gaps and what to ask
- IfOne estimate covers far less pipe than anotherThenAsk each contractor to point to the defects on the video that set their start and end points.
- IfRestoration is listed as excludedThenAsk what the site will look like when the crew leaves and plan for the rest.
- IfPermits are not mentionedThenAsk who applies and whether it is included. Check with the city if unsure.
- IfThe methods differThenAsk why the other method would not work on your pipe.
Before you choose
- Every row in the grid is filled in or has a question pending
- All license numbers checked at cslb.ca.gov
- I understand which defects each plan fixes and which it leaves
- I know how long the line will be out of service
- I have the scope and any change process in writing
Common questions
Is it rude to share one estimate with another contractor?
Sharing the camera footage is common. Sharing another company's pricing is up to you; the scope details are what matter for comparison.
What if two contractors disagree on the method?
Ask each to show the specific defects that drive their choice. A sag, collapse or offset often decides it.
Should I sign the estimate?
Only after the scope, exclusions and change process are clear to you.
