How to hire a general contractor

The short answer

If you need a new home, a home addition, structural work, or a major renovation, start by talking to more than one licensed general contractor. A good contractor can coordinate trades, permits, scheduling, materials, and inspections. But the right fit matters. You are trusting this company with your home, your money, and months of work.

Mainstay Builders is a free matching service. We help homeowners get connected with licensed, bonded and insured general contractors in the U.S. We do not build, design, inspect, engineer, or give legal advice. You should always verify each contractor's license, insurance, and references yourself before signing any contract.

Why it matters for your project

A general contractor is often the main point of coordination on a big job. That includes lining up subcontractors, ordering materials, handling the schedule, helping with permits, and keeping the work moving. On a complex project, the contractor can affect cost, quality, safety, and how much stress you deal with.

The risk of choosing the wrong contractor is real. Poor communication can lead to delays. Weak planning can lead to change orders and budget surprises. Unlicensed or uninsured work can create serious problems if there is property damage, failed inspections, or injury on site. This is why it is so important to hire carefully and verify everything, even if someone was recommended by a friend or speaks your language.

For many families, especially first-time homeowners or households more comfortable in a language other than English, the process can feel confusing. That is normal. You do not need construction jargon to ask smart questions. You need clear written details, time to compare options, and a licensed pro you feel comfortable dealing with.

Step by step

Here is a practical way to hire a general contractor without rushing.

• 1. Define the project clearly. Write down what you want done, what problems you are trying to solve, and what matters most to you. Examples: add a bedroom, fix foundation movement, remodel the kitchen and move a wall, or build a new single-family home.
• 2. Gather plans or sketches if needed. For structural work, additions, and new builds, contractors usually bid more accurately when they have drawings, measurements, or engineering details. If you do not have plans yet, say that early.
• 3. Set a realistic budget range. You do not need an exact number, but it helps to know your comfort zone. Be honest about what you can spend so you do not waste time on options that are not workable.
• 4. Get matched with a few contractors. Mainstay Builders can connect you with licensed, bonded and insured general contractors who handle your project type and area. Matching is free. You still choose who to speak with and who to hire.
• 5. Check licenses and insurance yourself. Ask for the contractor's license number and verify it with your state or local licensing authority. Ask for proof of general liability insurance and, where required, workers' compensation coverage. Make sure the business name matches the paperwork.
• 6. Ask about similar jobs. You want a contractor who regularly handles projects like yours, not just any construction work. A company that does cosmetic remodels may not be the right fit for a structural addition or a ground-up build.
• 7. Request a written bid. The bid should spell out the scope of work, allowances, materials, labor, permit responsibility, estimated timeline, payment schedule, and what is not included. Vague bids are hard to compare and often lead to conflict later.
• 8. Compare apples to apples. One bid may look cheaper because it leaves out demolition, cleanup, fixtures, engineering, or permit fees. Read every line. Ask each contractor to explain differences in plain language.
• 9. Ask who will be on site. Find out who manages the job day to day, who your main contact will be, and how often you will get updates. A smooth project depends a lot on communication.
• 10. Check references and recent work. Ask for a few recent clients with similar jobs. When you speak with them, ask whether the contractor communicated well, handled changes fairly, showed up consistently, and resolved problems professionally.
• 11. Read the contract slowly. The contract should include the full scope, payment schedule, estimated start and completion windows, warranty terms if any, change-order process, cleanup expectations, and how disputes are handled. Do not sign blank spaces or unclear wording.
• 12. Never skip permits or inspections. If your project needs permits, use a contractor who is willing to pull the right permits and follow inspection requirements. A shortcut now can become a much bigger problem when you sell, refinance, or insure the home.

If English is not your first language, it is okay to ask for slower explanations, translated notes, or a family member to join calls. A trustworthy contractor should not pressure you for a same-day decision. You should understand what you are agreeing to before paying a deposit or signing anything.

What to ask before you hire

Good questions can save you money and stress. You do not need to sound like an expert. You just need direct answers.

• Are you currently licensed for this type of work in my state or city?
• Are you bonded and insured? Can you send proof?
• Have you done projects like mine in the last year?
• What is included in this bid, and what is not included?
• Who pulls permits, and who schedules inspections?
• Who will supervise the job each day?
• How do you handle changes if we find hidden issues or I want to revise something?
• What payment schedule do you propose?
• What could cause the timeline to move?
• Can I speak with a few recent clients?

Pay attention to how the contractor answers, not just what they say. Clear, patient communication matters. If someone avoids details, rushes you, or gets defensive about license checks, that is useful information.

Common mistakes

Many hiring problems start before construction begins. Homeowners are often under pressure, especially after a structural issue, storm damage, or a tight move-in deadline. That pressure can make a risky offer look tempting.

• Hiring the first contractor you speak with without comparing options.
• Choosing based only on the lowest price.
• Failing to verify license, bond, and insurance.
• Accepting a verbal promise instead of a detailed written contract.
• Paying too much up front or paying cash without records.
• Letting work start before permits are handled.
• Ignoring exclusions and allowances in the bid.
• Not asking who is actually doing the work and supervising the site.
• Assuming every contractor can handle every kind of project.
• Feeling too embarrassed to ask basic questions.

Another common mistake is comparing bids that describe very different work. For example, one contractor may include site prep, debris removal, permit coordination, and finish materials, while another leaves those items out. If you only look at the total price, you may think one is cheaper when it is simply less complete.

Watch for warning signs. Be careful with anyone who says a permit is not needed without explaining why, refuses to provide a license number, cannot show insurance, wants a very large deposit, or tells you the price is only good if you sign right now. You should have time to read and think.

Honest cost and time notes

There is no one national price for hiring a general contractor because the total depends on your project type, location, design choices, site conditions, code requirements, labor market, and permit needs. The figures below are broad U.S. estimates, not quotes or guarantees. Real bids can come in below or above these ranges.

Time is just as variable. A major renovation may take several weeks to several months. A home addition may take a few months or longer. A new build often takes many months and can stretch further with permitting, utility work, weather, custom materials, or inspection delays. Any timeline you hear early on should be treated as an estimate, not a promise.

Change orders are another big cost and time factor. If hidden damage is found, materials go out of stock, plans change, or code issues appear, the price and schedule can shift. Ask each contractor how they document changes. The safest process is written change orders approved by you before extra work moves forward.

Deposits and payment schedules vary by state, project size, and contractor policy. The key is that payments should be tied to clear milestones in a written contract. If you are unsure whether a payment schedule is reasonable, pause and ask questions before signing. Mainstay Builders cannot advise on legal terms, but we strongly recommend using a licensed, bonded and insured contractor and reviewing the paperwork carefully.

Next step

You do not have to figure this out alone. If you are starting a new build, planning an addition, dealing with structural work, or preparing for a major renovation, Mainstay Builders can help you get matched with licensed, bonded and insured general contractors in your area. The matching service is free for homeowners.

Once you are matched, take your time. Compare written bids. Verify credentials. Ask questions in plain language. Choose the contractor who is qualified for your project, explains things clearly, and gives you a contract you actually understand. The goal is not just to hire fast. It is to hire carefully.
