Questions to Ask Builder
Questions to ask a builder or general contractor before you sign, whether the job is a new house, an addition or a gut renovation. They cover licensing and insurance, who actually swings the hammer, how the price is built up, what happens when the scope changes, and how the schedule and warranty are written.
The questions
Open any question for the note
What kind of work makes up most of your business right now?
Why ask it
A builder whose last five jobs were tract houses will approach a 1920s remodel differently from someone who does nothing but old homes. The answer also shows whether your project is routine for them or a first attempt, and first attempts get paid for by the client.
Are you licensed in this jurisdiction, and can I have the license number?
Why ask it
Licensing rules vary by state and county, and some trades are separately licensed from general contracting. A number you can look up yourself tells you the status, the expiry and whether there is a complaint history attached.
What insurance do you carry, and can your agent send me the certificates directly?
Why ask it
You want general liability and workers compensation, and you want the certificate to come from the insurer rather than as a PDF from the builder. Uninsured labor on your property can leave an injury claim pointed at your homeowner policy.
Who will actually be on site every day, and are they your employees or subcontractors?
Why ask it
Many builders sell the owner and then hand the job to a crew you never met. Ask who the lead carpenter is, how many other jobs that person is running at the same time, and whether the subs are long-term relationships or whoever bid lowest this month.
Can I see two or three projects like mine, including one you finished a couple of years ago?
Why ask it
Fresh work always photographs well. An older project shows you whether the caulk lines held, the floors stayed flat and the owner still speaks warmly about the builder after the honeymoon ended.
Can I talk to a client whose job went badly, or who you had a disagreement with?
Why ask it
Every builder with real volume has one. Someone who names it and explains how it resolved is describing their actual conflict behavior, and someone who claims to have never had a problem client is either new or not being straight with you.
Is this a fixed price or cost plus job, and what is your fee or markup?
Why ask it
The two structures put the risk of overruns in completely different places. On cost plus you need the markup percentage and to know whether it applies to your own purchases and to change orders too.
Can I see the estimate broken out by trade rather than as one number?
Why ask it
A line-item breakdown lets you compare bids honestly and see where a suspiciously low price is hiding, usually in allowances or excluded scope. A builder who will only give you a lump sum is asking you to trust arithmetic you cannot check.
Which items are allowances rather than firm prices, and what number did you use for each?
Why ask it
Tile, lighting, plumbing fixtures, appliances and countertops are the usual allowance categories, and a low allowance makes a bid look cheap while guaranteeing an overage. Ask what a client with your taste typically spends against each one.
What is specifically excluded from this bid?
Why ask it
Exclusions are where bids differ most: permits, dumpsters, temporary power, painting, landscape repair, appliance hookup, engineering. The exclusion list is often more informative than the inclusion list.
Who pulls the permits, and who is listed as the responsible party?
Why ask it
If the permit is pulled in your name as owner-builder, the code liability and any unpermitted work fall on you, not the builder. That arrangement is sometimes a sign the builder cannot pull permits themselves.
How do you handle change orders, and will I see the price before the work happens?
Why ask it
The pattern to avoid is verbal approval followed by a surprise on the next invoice. Ask for written change orders that state both the cost and the added days, and confirm that nothing proceeds until you sign.
What is your payment schedule, and how much do you want up front?
Why ask it
Payments should follow completed work, not the calendar. A large deposit relative to the contract can mean the builder is funding another job with your money, and many states cap what a contractor may collect before starting.
Do you use lien waivers from your subs and suppliers as you get paid?
Why ask it
A sub who never got paid can lien your house even though you paid the builder in full. Signed waivers tied to each draw are the ordinary protection, and a builder unfamiliar with them is a real warning.
When can you actually start, and what else are you running at the same time?
Why ask it
A builder who can start immediately in a busy market may have just lost a job or be short on work. One booked six months out is usually a better sign, as long as they will commit the start date in writing.
How long will this take, and what are the two or three things most likely to slow it down?
Why ask it
The named risks matter more than the duration. Listen for realistic answers like plan review, a long-lead window package or the possibility of hidden rot, rather than a confident number with nothing behind it.
How will you keep the site, and what will living here be like during the work?
Why ask it
Dust barriers, where the dumpster goes, working hours, bathroom access and whether utilities get shut off decide whether you can stay in the house. Builders rarely volunteer this, and it is the part of the job you feel every day.
How do you prefer to communicate, and how often will I hear from you?
Why ask it
Some builders run a weekly site meeting and a shared project log, others answer texts whenever they can. Neither is wrong, but a mismatch between their habit and your expectation produces most of the friction on a job.
What happens if you open a wall and find something unexpected?
Why ask it
In older homes this is a near certainty: knob and tube wiring, no header, water damage, asbestos. You want to know whether they stop and price it with you or keep working and bill you later, and whether they carry a contingency.
What is your warranty, and how do you handle a punch list and callbacks after the job is done?
Why ask it
Warranty length matters less than the response habit. Ask how long a callback typically takes once a crew has moved on, since a builder mid-project is far more attentive than one who has already cashed the final check.
Hiring a Builder Without Getting Burned
Practical guidance for the conversation itself
Before You Meet Anyone
Write down your scope first
Even a rough one-page description of what you want done, plus any drawings you have, lets every builder bid the same job. Without it you will get bids that are not comparable and you will end up choosing on price alone.
Decide your real budget and your walk-away number
Builders will size the project to whatever you tell them. Know the figure you are willing to go to if something is found behind a wall, and keep roughly ten to twenty percent of the contract aside for it.
Get three bids, not two
Two bids tell you nothing about which is the outlier. Three gives you a middle, and if one comes in far below the others the difference is almost always in exclusions or allowances rather than efficiency.
During the Walkthrough
- Ask the price questions and the process questions in separate passes. Builders are rehearsed on price and much less rehearsed on how they handle a discovered problem.
- Notice whether they measure and take notes or just talk. A builder who leaves without writing anything down is going to bid from memory.
- When they say a number, ask whether it is fixed, an allowance or a guess. Those three words are the whole difference between bids.
- Ask what they would do differently from your plan. A builder who has no opinion is either not engaged or is planning to build exactly what you drew, mistakes included.
- Say nothing about the other bids' numbers. Once a builder knows the price to beat, you stop learning what the job actually costs.
Warning Signs
A large deposit, or cash only
A builder who needs a big payment before any work starts, or who prefers cash and offers a discount for skipping paperwork, is telling you about their finances. Cash also leaves you no record if you later need to prove what you paid.
Pressure to sign today
Special pricing that expires, or a claim that the crew is free this week only, is a sales tactic and not a construction reality. Good builders are usually trying to get you to wait, not hurry.
Reluctance about permits or inspections
Suggesting the job can skip a permit to save time or money puts the code violation on your title, not theirs. It also complicates insurance claims and shows up when you sell.
No written contract, or a one-page one
A real contract names the scope, the drawings by revision, the price structure, the payment schedule, the change order process, the start and completion dates and the warranty. Anything much shorter is leaving the disputes for later.
Checking Them Out Afterward
- 1Look up the license number yourself with the state or county licensing board rather than trusting a number on a business card.
- 2Ask the insurer, not the builder, to send certificates for liability and workers compensation, and confirm the coverage dates cover your whole job.
- 3Call references and ask specifically about how change orders and problems were handled, not whether they were happy.
- 4Search local court records for the business name and the owner's name to see any construction litigation or liens.
- 5Ask a supplier or lumberyard in town whether the builder pays on time. Trade credit reputation is hard to fake and easy to ask about.
