Compare scope before price
For a water heater replacement, a slab leak repair or a repipe, the lowest total is not always the cheapest outcome. One estimate may include seismic strapping, a permit and haul-away; another may leave them out or treat them as extras. One may include drywall patching; another may stop at the pipe.
Fill in the table from each written estimate, word for word where you can. Where an estimate is silent, write 'not stated' and ask about it.

Red flags while comparing
- No license number, or a name that does not match the license
- A very short description such as 'fix leak' with no detail
- No mention of permits on work that likely needs one
- Pressure to sign the same day for a non-emergency
- Very different diagnoses that no one has explained
When estimates disagree
- Ask each contractor to explain the diagnosis.How they found the problem and what they saw.
- Ask about the missing items.Request a revised estimate that states inclusions and exclusions.
- Compare the long-term plan.A spot repair and a reroute solve different problems over different time frames.
- Decide in writing.Sign only the version that matches what you agreed to.
Questions that level the field
- If this were your house, which option would you choose and why?
- What would make the price change once work starts?
- What does the warranty cover, and for how long, in writing?
Common questions
How many estimates should I get?
Two or three is common for larger jobs. For urgent repairs, one careful estimate plus a license check may be enough.
Is it fair to share one estimate with another contractor?
Many homeowners describe the scope rather than sharing the document. Either way, ask each contractor to diagnose independently.
What if one estimate recommends replacement and another repair?
Ask both to explain the condition of the equipment or pipe and how long each option is expected to last.
