The main red flags are a vague scope, no license number, a price far below the other bids, a large payment demanded up front, and pressure to sign quickly. A bid should tell you exactly what you are buying. If it cannot, you have no way to compare it or hold anyone to it.
Vague wording is the most common problem. A line that reads "remodel bathroom, $20,000" does not say which fixtures, tile or finishes are included, or what happens to the old materials. Look for allowances set too low for the finishes you discussed, since the price will climb once you make real selections. Missing exclusions are a warning too, because anything left unsaid can become an argument or an added charge later.
A bid well below the others deserves a direct question: what is different? It may leave out work the other bids include, assume cheaper materials, or skip steps. Compare bids line by line rather than by the total. Be careful with an unusually large deposit as well. California limits down payments on home improvement contracts, and the CSLB website explains the current rule, so check it before you pay.
Watch how the contractor behaves, not only what the paper says. Warning signs include a discount that expires today, a request for cash only, no license number on the bid, or a suggestion that you skip a permit the job actually requires. Legacy provides a written estimate before any work starts, and you are welcome to take your time with it and compare it against other bids.
