5 red flags when getting contractor quotes
Most people get one quote and hope for the best. Here's what to actually pay attention to.
We looked at how homeowners actually shop for contractors, and the numbers aren't great. Close to half only get a single bid before signing a contract. Another fifth get two. So roughly two out of three people are making a five-figure decision with almost nothing to compare against. (If you need a starting point, our home improvement cost guide covers real pricing for every major project type.)
If you're here, you probably already have a quote in hand and something about it doesn't sit right. Here's what to pay attention to.
The quote is a single number with no breakdown
A contractor hands you a sheet that says “Kitchen remodel, $28,000.” No line items. No separation between materials and labor. Nothing about what's actually included or how long it takes.
Easy to overlook because a lot of contractors do it. They're busy, they've been quoting this way for years, and writing up a real breakdown takes time. But a lump sum makes it nearly impossible to compare against other bids. It also means they can swap in cheaper materials or skip steps and you wouldn't know until something goes wrong.
Ask for an itemized version. If they won't provide one, that's information. If they can't, that's more information.
The price is way below everyone else
Low bids feel like you won something. In practice, they're usually a problem.
When a quote lands 30-40% under the rest, something is off. Maybe they're using cheaper materials than what you discussed. Maybe they're not planning to pull permits. Maybe they're subbing the actual work out to someone you've never spoken to. Or they're lowballing to get the job, knowing they'll make it up in change orders once your walls are open and you can't easily walk away.
A contractor quotes $14,000 for a bathroom. Two weeks in, “we found some issues behind the wall” and now it's $21,000. Your bathroom has no floor at this point. You don't have a lot of options.
If one bid is dramatically lower than the others, just ask why. The answer either makes sense or it doesn't.
They want you to decide right now
“This price is only good today.” “I've got another job lined up so I need an answer by Friday.” “I can take 10% off if you sign tonight.”
Real scheduling constraints exist. But most of the time this is pressure to stop you from getting competing bids. Contractors who do solid work at fair prices generally don't need to rush you. Their quote holds up next to anyone else's.
A contractor who won't give you a few days to think is a contractor who doesn't want you thinking.
They want half the money before starting
Some deposit upfront is normal. Materials cost money and the contractor isn't financing your project for free. 10-15%, or a materials-only payment, is standard for most residential work.
50% upfront before anything starts is not standard. Neither is the full amount. This is where homeowners get hurt the worst. The contractor collects the check, does a day of demo to show progress, then slows to a crawl or vanishes entirely. The financial incentive to finish has largely disappeared.
What you want is a payment schedule tied to actual work. First payment covers materials. Second comes when rough-in is complete. Final payment after a walkthrough. If the money is mostly flowing before the work is mostly done, renegotiate the schedule.
The scope is missing or deliberately vague
“We'll handle the plumbing.” Great. Does that include moving the water heater? Replacing supply lines? What about the shutoff valves that are 30 years old?
Vague scope is where almost every contractor dispute starts. The homeowner assumed something was part of the job. The contractor says it wasn't. Now you're arguing over $2,000 while your kitchen has no sink.
A useful quote spells out what's included and what isn't. If there's no mention of permits, dumpster rental, or final cleanup, don't assume those are covered. Ask.
So what do you do with this?
Spotting one of these doesn't necessarily mean the contractor is trying to rip you off. Some of it is just sloppy business practices, which is its own kind of risk when you're handing someone the keys to your house for six weeks.

Either way, the move is the same: get more detail and get more quotes. You can check your quote against real data to see where it falls. Call their references. Look up their license number with your state board. Most have an online lookup tool and it takes two minutes.
Homeowners tell us constantly that they had a bad feeling early on and talked themselves out of it. Don't do that. The good contractors won't mind your questions. They're used to following bad ones.
