Two quotes for 'replace main water line' can describe very different jobs. One may include a new shutoff, a permit and concrete repair; another may stop at backfill. Copy each quote into the grid below, one column per contractor. Wherever a box stays empty, call and ask. A blank usually means the item is not included, and that is worth knowing before you sign.

Using the grid
- Fill every row.Copy details straight from each written quote, not from memory of a phone call.
- Mark the gaps.Circle any blank and ask the contractor to answer it in writing.
- Normalize the scope.If one quote excludes restoration or a shutoff, ask the others to price it the same way.
- Compare totals last.Only once the scopes match is a price comparison meaningful.
A lower total versus a fuller scope
Lower total, thin scope
- May leave out permits or restoration
- Extras appear as change orders later
- Harder to hold to a clear standard
Higher total, detailed scope
- Includes items you would pay for anyway
- Fewer surprises once digging starts
- Easier to check the finished work against
Common questions
Should I always choose the middle quote?
Not automatically. Choose the quote with a clear, complete scope from a verified licensed contractor whose plan makes sense for your lot.
Can I ask one contractor to match another's scope?
Yes. Asking each to price the same scope is the fairest comparison.
What if contractors disagree on repair versus replace?
Ask each what they saw that led to their recommendation. The reasoning matters as much as the price.
