10 Questions to Ask a Custom Home Builder Before You Sign

You've picked the neighborhood. You've daydreamed about the floor plan. You have a rough budget in your head.

Now comes the part that actually determines whether this experience is exciting or miserable: choosing who builds it.

The builder you hire will control your money, your timeline, and the quality of the place where your family sleeps every night. That's not a decision you make based on who has the nicest website or the lowest bid.

It's a decision you make by asking the right questions and listening carefully to the answers.

After building custom homes in Midland since 2003, I've heard every version of "I wish I'd asked that before we started." So here are the 10 questions that matter most, what good answers sound like, and the red flags that should make you walk away.

1. How Long Have You Been Building, and Can I See Your Work?

This isn't small talk. It's your first filter.

Experience alone doesn't guarantee quality. But a builder who's been at it for 10+ years has survived market downturns, dealt with difficult subcontractors, solved unexpected problems, and kept their reputation intact through all of it.

What a good answer sounds like: "We've been building in Midland for [specific number] years. Here's our portfolio. We've completed homes similar to what you're describing. And here are three families you can call."

Red flags:
• Vague answers about how many homes they've completed
• No portfolio or only renderings (no finished homes)
• Changed business names multiple times in recent years
• Can't point to completed projects you can actually visit

Take a look at their work in person if you can. Photos are helpful, but walking through a finished home tells you things a camera can't. Check out the trim work. Open the cabinets. Look at the grout lines. The details reveal the builder's standards.

Browse our project portfolio to see what we mean by attention to detail.

2. What Type of Contract Do You Use?

This question alone can save you tens of thousands of dollars. There are three main contract structures, and each one changes your risk:

With fixed-price, you know exactly what you're paying. The builder takes the risk if materials spike or something goes wrong. The trade-off? They've built a buffer into the price, and changes are harder to make mid-build.

With cost-plus, you see every invoice and every receipt. Full transparency. But here's something most people don't realize: if your builder's fee is a percentage of total cost, they actually make more money if your project costs more. That's a misaligned incentive. Ask whether the fee is a fixed dollar amount or a percentage.

What a good answer sounds like: "We use a [specific type] contract. Here's a sample for you to review with your attorney. It includes the full scope of work, allowance amounts, draw schedule, change order process, and warranty terms."

Red flags:
• Won't provide a sample contract before you commit
• Gets defensive when you mention having an attorney review it
• Contract is vague on scope, timelines, or payment terms

3. What Exactly Is Included in Your Allowances?

This is where bids get manipulated. Pay attention.

An allowance is a dollar amount set aside for items you haven't selected yet (flooring, cabinets, fixtures, countertops). It lets the builder quote a price before you've picked every tile.

The problem? Some builders use artificially low allowances to make their bid look cheaper. They'll put $5,000 for lighting when realistic lighting for your home costs $12,000. You don't find out until you're shopping and everything you like costs more than the allowance.

Ask specifically:
• What's the lighting allowance, and what does that actually buy me?
• What's the cabinet allowance, and can you show me real examples in that range?
• What's the flooring allowance per square foot?
• If I go over an allowance, what's the markup on the overage?

What a good answer sounds like: "Your lighting allowance is $8,000. That gets you [specific fixture examples]. If you want to upgrade to [example], the overage would be approximately $3,000, and we mark that up at [X]%."

Red flags:
• Won't itemize allowances ("it's all included")
• Can't show you what the allowance amount actually buys
• Gets evasive about overage markups

A realistic allowance budget is roughly 17% of total project cost for a mid-range custom home. If the allowances seem low compared to the overall bid, they probably are.

4. What's Your Payment Schedule?

The draw schedule tells you when you pay and how much. Standard custom home builds use 5-7 milestone-based payments:

• Deposit (typically 10%)
• Foundation complete
• Framing/dried-in (weather-tight)
• Rough-in complete (HVAC, plumbing, electrical inspected)
• Interior finishes (drywall, flooring, trim, fixtures)
• Final completion and certificate of occupancy

Each draw is roughly 10-25% of total cost, and payments should track the percentage of work completed.

What a good answer sounds like: "We use a 6-draw schedule tied to construction milestones. Here's exactly what each draw covers and when it's due."

Red flags:
• Asks for more than 10-15% upfront
• Front-loaded schedule where you've paid 60%+ before the house is framed
• Requests cash-only payments
• No written draw schedule in the contract

Also ask about retainage. This is 5-10% of the total that gets withheld until everything is complete, including the punch list. It gives you leverage to make sure the last details get finished. If the contract doesn't include retainage, negotiate for it.

5. How Do You Handle Change Orders?

Every build has changes. You'll see something during framing and want to move a window. You'll upgrade the kitchen faucet. Something unexpected will come up with the site.

What matters is how changes are handled and how they affect your budget.

Ask specifically:
• Is the change order process defined in the contract?
• Do you provide written cost estimates before starting any change?
• What's the markup on change order work?
• How do changes affect the timeline?

What a good answer sounds like: "Changes happen on every project. We document them in writing with a cost and timeline impact before any work starts. You sign off, then we proceed. Our markup on change orders is [X]%. And we recommend setting aside 5-10% of your total budget as a contingency."

Red flags:
• No formal change order process
• Verbal-only change approvals ("don't worry, we'll figure it out later")
• High markups on changes (significantly above original contract margins)
• Builder seems to discourage all changes (inflexibility can be a sign of poor project management)

Industry recommendation: set aside 5-10% of your total construction budget for change orders and unexpected costs. If your selections are mostly finalized before breaking ground, you can stay toward the lower end.

6. Who Will Be My Point of Contact During Construction?

The person you're talking to during the sales process is often not the person you'll deal with during construction. Find out who that person is before you sign.

Ask specifically:
• Who is the project manager or site superintendent for my build?
• Can I meet them?
• How often will I get progress updates, and in what format?
• Can I visit the jobsite? How much notice do I need?

What a good answer sounds like: "Your project manager will be [name]. They'll send you weekly photo updates and a written progress report. We schedule a walkthrough at each major milestone. You're welcome to visit the site with 24 hours' notice."

Red flags:
• "You'll deal with whoever is available"
• No defined communication schedule
• Builder is slow to respond during the sales process (it only gets worse during construction)
• Gets annoyed by questions

This one matters more than people realize. The quality of communication during construction directly predicts how stressful the experience will be. A builder who communicates proactively prevents 90% of the conflicts that make building a home miserable.

7. What Warranty Do You Offer?

The industry standard is the 1-2-10 warranty:

What a good answer sounds like: "We provide a 1-2-10 warranty. Year one covers all workmanship. Two years on mechanical systems. Ten years on structure. We handle warranty service ourselves. When something comes up, you call us directly and we fix it."

Red flags:
• No written warranty
• Warranty shorter than 1-2-10 without a clear explanation
• "Call the subcontractor directly" (the builder should own the relationship)
• Won't put warranty terms in the contract

One trend worth knowing: some production builders are beginning to shorten structural warranties. Make sure you get 10 years on structural in writing.

8. Can I Talk to Past Clients (and Visit a Home You Built 2-3 Years Ago)?

References are standard. But most people only call the three families the builder hand-picked. Push further.

Ask specifically:
• Can I speak with 3-5 references, including at least one project similar in size to mine?
• Can I visit a home you built 2-3 years ago, not just a fresh build?
• Can I talk to a current client whose home is under construction right now?

The 2-3 year-old home is the key request. Fresh builds look great. But a home that's been lived in for a couple of years reveals how the foundation held up, whether the finishes lasted, whether the builder honored warranty claims, and how responsive they were after the final check cleared.

What a good answer sounds like: "Absolutely. Here are five families. Two are in homes we built recently, one is mid-construction, and two have been in their homes for 3+ years. Call any of them."

Red flags:
• Won't provide references
• Only offers references from projects built in the last 6 months
• Gets defensive about the request
• Has negative reviews on Google, BBB, or Houzz that they can't explain

9. How Do You Handle the Foundation on My Specific Lot?

This question is especially important in West Texas. Our soil conditions are some of the most challenging in the state.

Expansive clay soils here can swell up to 12-30% in volume when they get wet, then shrink during drought. That cycle generates enormous pressure on foundations. According to industry estimates, it's responsible for roughly 65% of all foundation problems across Texas.

Add in caliche (the hard, white calcium carbonate layer common in our area) and the fact that conditions can change dramatically from one lot to the next, even within the same subdivision. Foundation design is not something you guess at.

Ask specifically:
• Do you require a geotechnical soil test before designing the foundation?
• Do you use a licensed structural engineer for foundation design?
• What type of foundation do you typically recommend for our area?
• How do you handle drainage around the foundation?

What a good answer sounds like: "We require a soil test on every lot. The results go to our structural engineer, who designs the foundation specifically for your site. Most homes in Midland use post-tension slab foundations, but the specs (slab thickness, number of cables, footing depth) depend on what the soil report says. We also engineer proper drainage to manage moisture around the perimeter."

Red flags:
• Doesn't mention soil testing
• Uses a one-size-fits-all foundation design
• No engineer involved
• Dismisses soil concerns ("we've never had a problem")

This isn't where you cut corners. According to warranty industry data, the average structural foundation claim costs around $42,000. Getting it right the first time costs a fraction of that.

10. What Happens If We Disagree?

Nobody wants to think about disputes. But the time to address it is before you sign, not when you're in the middle of construction and emotions are running high.

Ask specifically:
• Is there a dispute resolution clause in the contract?
• Do you use mediation, arbitration, or litigation?
• Who pays the costs of dispute resolution?
• What happens if either party wants to terminate the contract?

What a good answer sounds like: "Our contract includes a dispute resolution process. We start with a direct conversation. If that doesn't resolve it, we go to mediation with a neutral third party. Arbitration is the final step. The contract spells out how costs are shared and what happens if we need to part ways."

Red flags:
• No dispute resolution clause
• Forces you into binding arbitration with a company they chose
• Termination clause only favors the builder
• Acts offended that you'd even ask

One Texas-specific item to know: Texas law allows contractors and subcontractors to file mechanics liens if they're not paid. Your contract should require the builder to provide signed lien waivers from subcontractors as payments are made. This protects you from a subcontractor putting a lien on your home because the builder didn't pay them. It's your house. Make sure the contract keeps it that way.

The Bonus Question: Why Should I Hire You?

After asking the first 10, sit back and listen to how they answer this one.

The best builders won't give you a sales pitch. They'll talk about their process, their team, the pride they take in their work. They'll tell you about problems they solved on past builds. They'll be honest about what they're great at and what's not their specialty.

The ones to avoid? They'll talk about how busy they are, pressure you to sign quickly, or tell you everything you want to hear without any specifics behind it.

Trust your gut. If someone feels off during the sales conversation, they'll be worse when they have your money and you're nine months into a build.

Frequently Asked Questions About Choosing a Home Builder

Does Texas require home builders to be licensed?

Texas does not require a statewide general contractor license. It's one of the few states without one. That means almost anyone can call themselves a builder. Specialized trades (electrical, plumbing, HVAC) do require state licensing, but general contractors don't. Local municipalities like Midland require contractors to be registered and bonded with the city to pull building permits. This makes vetting even more important. The barrier to entry is low, so the responsibility falls on you to verify experience, insurance, and references.

How many builders should I interview before choosing?

Three to five is a good range. Fewer than three and you don't have enough comparison. More than five and you'll start confusing details. Bring the same questions to each meeting so you can compare apples to apples.

Should I always go with the lowest bid?

No. The lowest bid often means the builder used artificially low allowances, cut the scope somewhere, or is less experienced at estimating. Compare bids line by line. Make sure you're comparing the same scope, the same allowance levels, and the same quality expectations. A low bid that results in $80,000 of overages isn't actually low.

What insurance should a builder carry?

At minimum: general liability insurance and workers' compensation. General liability covers damage to your property during construction. Workers' comp covers injuries to workers on your jobsite. Without workers' comp, you could be liable if someone gets hurt building your house. Ask for current certificates and verify they're valid.

How do I verify a builder's reputation?

Check multiple sources. Google reviews, BBB rating, and Houzz are good starting points. But also ask for references and actually call them. Visit a home they built 2-3 years ago. Drive by their current jobsites (a messy, disorganized site tells you something). Search their business name online for any lawsuits or complaints. In Midland, word of mouth matters. Ask around.

What should a builder contract include?

At minimum, your contract should cover: detailed scope of work, specific material and finish specifications, itemized allowances, total price, draw schedule, projected start and completion dates, change order process and markup rates, warranty terms, dispute resolution process, termination conditions, and lien waiver requirements. If any of these are missing, push back before signing. Have a real estate attorney review the contract. The $500-$1,000 for legal review is cheap insurance on a $700,000+ project.

When should I start looking for a builder?

Six to twelve months before you want to break ground. Good builders book out. The interview process takes time. Design and preconstruction planning adds weeks or months. If you wait until you're ready to start, you'll either rush the decision or wait for the builder's next opening. Learn more about the typical timeline in our process guide.

Is it okay to ask a builder about their subcontractors?

Absolutely. A good builder will be proud of their trade partners. Ask who does their electrical, plumbing, framing, and HVAC work. Ask how long they've worked together. Consistent, long-term subcontractor relationships are a sign of quality. Builders who shop for the cheapest sub on every project tend to get inconsistent results.

The Real Test

Here's what it comes down to: a builder who welcomes questions is a builder who has nothing to hide. The right builder won't just tolerate your questions. They'll be glad you asked them. They know that informed clients make better decisions, and better decisions lead to better builds.
