What Should I Ask a Builder Before Signing a Contract? 10 Questions From a Northern Virginia Builder
Quick answer
The ten questions worth asking a custom home builder or renovation company before you sign are:
What happens when there's a problem and how will it affect my budget and schedule?
Who is actually running my project day to day and will I meet them?
Who are your subcontractors and how long have you worked with them?
Can I talk with your recent clients and not just your favorite references?
Can I walk an active job before the walls are covered?
How will I see real costs during the build?
Do you mark up allowances or materials and do vendor discounts pass through to me?
What quality control do you enforce beyond what’s required by code?
What will you never cut even if the budget gets tight?
Are you licensed and insured in my jurisdiction and can I see the certificates?
Most homeowners interview builders on price and timeline, and every builder has a rehearsed answer for both. These ten tell you more about how a builder will perform after the contract is signed. The answers, and how fast they come tell you more than any portfolio. We build in Arlington, Fairfax, Falls Church, McLean, Great Falls, Alexandria, and Washington, D.C., and we would rather you ask us all ten than not.
Why price and timeline don't always tell you everything
Every builder you interview will give you a number and a schedule. Those answers are rehearsed and they aren’t always comparable, because you have no idea what is inside them. One builder's $1.4 million includes a $150,000 allowance package and another's doesn’t. One builder will go the extra mile using quality materials and a full sound insulation package and another won’t.
The questions below are different. They are about specific decisions that get made months from now, out of your sight, on days when you aren’t there. A builder who has thought hard about those decisions will answer immediately and in detail. A builder who hasn't will get vague. Vague is the answer.
1. What happens when there's a problem and how will it affect my budget and schedule?
Not if. When. Ask how fast you will hear about it, whether you will see real numbers attached, and how a change gets approved before the work happens. Every project has surprises. We have opened walls in 1920s Arlington homes and found knob and tube, no header over a bearing wall, and forty years of slow plumbing leaks. That is normal.
A good answer sounds like: a process. You hear within a day, you get the cost and the schedule impact in writing, and nothing proceeds until you approve it. We send real-time cost to date numbers at each draw request and weekly updates with photos and summaries to keep you in the loop throughout the project.
A weak answer sounds like: “We'll handle it.” The difference between builders is whether you find out in week three with a number attached, or at the final walkthrough with an invoice attached.
The same logic applies after you move in. Ask what the warranty actually covers and who picks up the phone a year after you move in. Here's Ours → Warranty: We Don't Disappear
2. Who is actually running my project day to day and will I meet them?
Ask whether it is the person sitting across from you. On our jobs it is Clayton or Christian, start to finish. We are two brothers and we run a deliberately small number of projects at a time for exactly this reason.
If the answer is a project manager, ask two follow-ups: how many years of experience do they have, how many jobs is that person running right now, and what happens if they leave the company mid-build? All three answers are informative and none of them are usually rehearsed. Then ask to meet them before you sign, not after.
3. Who are your subcontractors and how long have you worked with them?
The framer, the plumber, the electrician, the tile installer. Are these ten-year relationships or whoever bid cheapest this month?
Your house is built by those people, not by the person you are interviewing. A builder with a stable crew has spent years training them to his standard. A builder who shops every trade on every job is delivering you the low bid's workmanship at his price.
A builder who can’t name a consistent team of subcontractors usually has a reason.
4. Can I talk with your recent clients and not just your favorite references?
Ask for recent, not just your favorites.
A good answer sounds like: immediate yes, with names and numbers, including a project that had real problems. Any builder with eight years of work has recent clients they can offer as referrals.
A weak answer sounds like: a curated list from four years ago, or references who all happen to be family friends.
When you get them on the phone, skip "were you happy." Ask what surprised them, how fast the builder responded when something went wrong, and how they communicated from start to finish.
5. Can I walk an active job before the walls are covered?
A finished house tells you about the quality of the finishes. An open wall tells you about the builder.
Ask to walk an active job at the framing or rough-in stage. Look at whether the framing is straight and the blocking is there, whether plumbing and HVAC runs are organized or fought in later, whether the site is clean, and whether the crew seems to know who you are and why you are there.
A good answer sounds like: yes, and here is when. We take prospective clients through active jobs regularly, and the crews expect it.
A weak answer sounds like: "Our sites aren't really set up for visitors." Every site is set up for visitors if the work is good and the job site is safe.
If you want to see how we run a job before you ask to walk one, Our Process walks through it stage by stage.
6. How will I see real costs during the build?
Not a summary. Actual costs, at set intervals, with invoices available to you upon request.
A good answer sounds like: a named system, a schedule, and access. "A draw request schedule with real time costs to date at each and access to the project portal.”
A weak answer sounds like: "We'll keep you updated." Ask what that means specifically. If the answer is a phone call when something changes, you are being managed, not informed.
This one depends heavily on contract type. A fixed-price builder has no obligation to show you costs at all, because the number is the number. We wrote a full breakdown of why that matters in Cost-Plus vs Fixed Price, and How We Price lays out our draw schedule and reporting.
7. Do you mark up allowances or materials?
Ask it plainly. Then ask the follow-up that matters more: do builder and vendor discounts pass through to me, or stay with the builder?
This is one of the most common places where money moves quietly. A builder can quote you a competitive fee and make it back three times over on a 20 percent markup on cabinetry and appliances.
On our cost-plus contracts, allowances sit outside our fee entirely. Upgrade the countertop and we earn exactly the same, so nobody here has a reason to push you toward a more expensive slab or away from one. The full explanation, including where our contract is not perfect either, is in Cost-Plus vs Fixed Price and on How We Price.
8. What quality control do you enforce beyond what’s required by code?
County inspections confirm your house is legal. They do not confirm it is well built. An Arlington County framing inspection takes about fifteen minutes and checks a short list.
Ask what the builder checks that the inspector does not, and ask what gets documented.
For us the answer is a complete pre-drywall photo record on every project. Every pipe, wire, stud, and blocking location, delivered through the client's project portal and theirs permanently. Ten years from now, when you want to hang a 200-pound mirror or add a fixture, you will know exactly what is behind the wall. Most builders in Northern Virginia do not do this.
Ask anyway, because the answer tells you how a builder thinks about your house after they leave it. You can see what a real pre-drywall record looks like on Behind the Walls.
9. What will you never cut even if the budget gets tight?
Everyone has a budget conversation eventually. You want to know in advance which things are off the table.
A good answer sounds like: a short, specific list with named systems and numbers behind it.
A weak answer sounds like: "We work with you on everything." That means nothing is off the table, including things that should be.
For us it is the bones, and here is what that means in specifics:
Waterproofing. Full Schluter systems in showers, bonded waterproofing rather than a pan liner under mud. A shower pan failure is the most expensive thing that can go wrong behind tile, and the cheap way and the right way look identical once the tile is installed. Ask any builder what system he uses and why that one. If he says "our tile guy handles that," you have your answer.
Floor deflection. Code minimum under the Virginia Residential Code is L/360. That is a legal floor, not a quality target. We build to L/480 and L/600 under tiled bathrooms. The difference is whether your floors bounce when someone walks across the room and whether your grout cracks in year three. You cannot change it later without opening the ceiling below.
Subfloor. Three-quarter-inch AdvanTech rather than standard OSB. That is a squeak and moisture question more than a strength one.
Foundation, framing, and roof. Not value-engineered, ever.
Building envelope. Above all windows, doors, and band boards we use a roofing brake to bend metal flashing on site. This is the traditional method of installing flashing to prevent water intrusion, instead of using the cheap pre-bent flashing available at the big box stores.
Everything you can see and change later is fair game in a budget conversation. Everything buried is not.
10. Are you licensed and insured in my jurisdiction and can I see the certificates?
In Virginia, a project over $120,000 requires a Class A contractor license from DPOR. You can verify any license yourself in about a minute at the DPOR license lookup, and you should, because a license number printed on a truck is not proof it is current.
Ask for a certificate of insurance naming general liability and workers' compensation. If your project is in Washington, D.C., a Virginia license does not cover it. D.C. requires its own Home Improvement Contractor license and Basic Business License through DLCP. Ask specifically about the jurisdiction your house is in.
We are Virginia Class A, DPOR 2705170445, and we will send the certificate before you ask. We have both the Home Improvement Contractor license and the Basic Business License required by Washington, DC and we’re happy to share it with you.
A moment of candor
We put this list on our own website to help future customers vet their builders and avoid those commonly told horror stories about contractors. Also, we know some competitors will read it and prepare answers, but if it makes them a better builder we’re on board..
We would also rather you ask us these questions than not. We have had consultations where a homeowner ran through something like this list and we could tell they were relieved by the answers. We have also had conversations where our answers made it obvious we were not the cheapest option in their stack, and they went a different direction. Both of those are better than finding out at framing that nobody asked.
FAQs
What questions should I ask a custom home builder before signing a contract? Ask what happens when a problem comes up and how it hits your budget and schedule, who runs the project day to day, who the subcontractors are and how long they have worked together, whether you can talk to recent clients, whether you can walk an active job site before drywall, how you will see real costs during the build, whether allowances are marked up, what quality control exists beyond county inspections, what the builder will never cut when budgets tighten, and whether he is licensed and insured in your jurisdiction.
How many builders should I interview? Three is usually enough if you are asking the right questions. More than that and you end up comparing numbers rather than approaches.
Should I pick the lowest bid? Not without understanding why it is the lowest. A number meaningfully below the others is telling you something about scope, materials, or what has been left out of the estimate. Ask what is different, line by line.
What questions should I ask the references a builder gives me? Ask what surprised them, how quickly the builder responded when something went wrong and whether they would hire them again. Skip "were you happy." Ask for recently completed projects rather than a curated list.
What are red flags when hiring a home builder? Rushing you to sign, vagueness about how costs will be reported, refusing to name subcontractors, refusing to let you visit an active job site, no documentation before drywall, and any version of "don't worry about that." Also a builder who agrees your budget works before he has looked closely enough to know.
Is it rude to ask a builder about markup? No. You are about to make one of the largest purchases of your life. Any builder offended by a direct question about how he makes money has told you something useful. Ask what their markup percentage is and what that includes and excludes.
How do I check if a builder is licensed in Virginia? Search the contractor's name or license number in the DPOR license lookup on the Virginia Department of Professional and Occupational Regulation website. Confirm the license is Class A if your project exceeds $120,000, confirm it is active, and confirm the business name matches the entity on your contract.
Do I need to ask different questions for a renovation than for a new build? Mostly no, but add one. Ask how unknowns behind existing walls get priced and approved. Renovation budgets move more than new construction budgets and unknown existing conditions are the reason why.
What should I ask a builder in Arlington or Falls Church specifically? Ask how many permits they have pulled in that jurisdiction in the last two years and what the current realistic review timeline is. Arlington County, Fairfax County, Falls Church City, and D.C. all move at different speeds, and a builder who works there regularly will give you a number without hedging.
Bring this list to us. We will answer all ten, and we will tell you honestly if we are not the right fit for your project.
