When three bids land on your kitchen table, the temptation is to scan for the smallest number and stop there. Don't. The lowest bid is often the one most likely to balloon. The goal isn't the cheapest price — it's comparing the same scope of work, priced honestly.
- A bid more than 20% below the others is a warning sign — usually missing scope or low-balled allowances that return later as change orders.
- Compare bids line by line, not by the bottom-line total. Make sure every contractor priced the same work.
- A real quote is itemized: scope, realistic allowances, a milestone payment schedule, dates, license number, and a written change-order process.
- Watch the allowances — artificially low ones make a bid look cheap but guarantee overruns.
Why the lowest bid is the riskiest
There are only a few ways one contractor can come in dramatically cheaper than the rest: they left work out of the scope, they're pricing lower-grade materials, they set unrealistic allowances, or they plan to recover the gap through change orders once you're committed. A bid that's more than about 20% below the others is rarely a bargain — it's usually an incomplete picture. By the time the missing items surface, your demolished kitchen gives you little leverage to push back.
That doesn't mean the highest bid is best either. The bid you want is the one that's complete, specific, and fairly priced for the work you actually asked for.
Level the bids before you compare
"Bid leveling" just means lining the quotes up so they describe the same job. Give every contractor an identical scope, then put the bids side by side and check each major line — demolition, framing, plumbing, electrical, cabinets, countertops, tile, paint, cleanup. If one bid is missing a line another includes, that's not savings, it's a gap. When a number looks too low for the work, ask. Reputable contractors are happy to explain their assumptions.
What a real quote includes
A serious estimate for a remodel is a document, not a text message. Look for:
- A detailed scope of work describing what will and won't be done.
- Realistic allowances for finishes, fixtures, and appliances, written at honest numbers — not placeholder figures designed to lower the total.
- A payment schedule tied to milestones (e.g., rough-in complete, cabinets set), not to the calendar, with a legal deposit.
- Start and completion dates.
- The CSLB license number and proof of insurance.
- A written change-order process so any change is priced and approved before work proceeds.
This is exactly how we structure a quote, and you can see how the job runs on our process page. For vetting the company behind the bid, our guide on how to choose a contractor walks through license, bond, and insurance checks.
The allowance trap
Allowances are the contractor's estimate of what you'll spend on items you haven't picked yet — tile, faucets, cabinets. They're normal, but they're also where a cheap-looking bid hides its true cost. If a bid sets the tile allowance at a price that barely covers builder-grade material, the total looks low until you walk into the showroom. Ask what each allowance assumes, and make sure the numbers reflect the finish level you actually want. Our remodeling costs guide gives realistic local figures to sanity-check them.
Questions to ask every bidder
- What's specifically excluded from this price?
- Are these allowances enough for the finishes we discussed?
- How are surprises behind the walls handled, and at what rate?
- Who pulls the permits, and is that cost in the bid?
- Can I see references from similar recent projects?
