Hiring a general contractor is one of the biggest decisions you’ll make for your home. The right contractor delivers quality work on time and on budget. The wrong one can cost you thousands of dollars, months of delays, and serious legal headaches. The difference almost always comes down to how well you vet them before signing anything.

This guide walks you through every step, from checking licenses to spotting red flags, so you can hire someone you can actually trust.

Key Takeaways

• Verify licensing and insurance before anything else. An unlicensed contractor puts you at financial and legal risk.
• Get at least three written quotes. This protects you from overpaying and exposes contractors who underbid to win work.
• Review past work in person when possible. Photos are easy to fake. Real job sites and references are not.
• Read every line of the contract. Scope, payment schedule, and change order terms are where disputes start.
• Red flags are deal-breakers, not negotiating points. Pressure tactics, cash-only demands, and no written contract are signs to walk away.
• A cheap bid is not a good deal. Unusually low quotes often signal corner-cutting, unlicensed work, or a setup for cost overruns.

What Does a General Contractor Actually Do?

Quick Answer: A general contractor manages your entire construction or renovation project. They hire and coordinate subcontractors, pull permits, order materials, and keep the job on schedule. You pay one person, and they handle the complexity of running multiple trades at once.

A general contractor (GC) is the central manager of a building or renovation project. They don’t always swing hammers themselves. Instead, they hire licensed tradespeople — electricians, plumbers, framers, tile setters — and coordinate their work from start to finish.

Their job includes pulling the required building permits, passing inspections, ordering materials at the right time, and keeping subcontractors accountable. If something goes wrong on the job, the GC is your single point of contact and responsibility.

Understanding this role matters because you’re not just buying labor. You’re buying project management, industry relationships, and professional accountability.

General Contractor vs. Subcontractor: What’s the Difference?

A subcontractor specializes in one trade, like plumbing or electrical work. A general contractor hires and oversees multiple subcontractors. If you hire a plumber directly, you become the project manager. If you hire a GC, they take that responsibility off your plate.

When Do You Actually Need a General Contractor?

You need a GC when your project involves more than one trade or requires permits. A bathroom remodel touching plumbing, electrical, and tile work needs a GC. Painting a room does not. A good rule of thumb: if the project takes longer than a week or crosses into structural or mechanical systems, hire a GC.

How Do You Verify a Contractor’s License?

Quick Answer: Every state has an online contractor license lookup database. Search your state’s contractor licensing board website, enter the contractor’s name or license number, and confirm their license is active, current, and covers your project type. Takes under five minutes.

Licensing requirements vary by state. Some states require general contractors to hold a statewide license. Others regulate at the county or city level. The type of work also matters — a license for remodeling doesn’t always cover new construction.

Ask your contractor for their license number before you meet. Then look it up yourself. Don’t take a copy of a card at face value. A license can expire or get suspended after a card is printed.

What to Check When Verifying a License

• License status: Active and in good standing, not expired or suspended
• License class: Matches the scope of your project (residential, commercial, specialty)
• Name match: The business name on the license matches what’s on their bid and contract
• Complaint history: Most state boards list formal complaints and disciplinary actions
• Expiration date: Valid through your project’s expected end date

What Insurance Should a General Contractor Carry?

Quick Answer: A legitimate general contractor carries two types of insurance: general liability and workers’ compensation. General liability covers property damage. Workers’ comp covers injuries to workers on your property. Without both, you could be financially responsible for accidents that happen on your job site.

Insurance is not optional. It protects you, not just the contractor. If a worker falls on your property and the GC doesn’t carry workers’ compensation, that injured worker could sue you directly as the property owner.

Always ask for a Certificate of Insurance (COI). This is a one-page document showing coverage types, policy limits, and expiration dates. Ask the contractor to have their insurance provider send the COI directly to you — not just hand you a copy.

How Do You Find Good Contractor Candidates?

Quick Answer: The best contractor leads come from personal referrals, local building supply stores, and verified review platforms. Avoid contractors who contact you unsolicited after storms or who only have online presence but no verifiable local project history.

Word of mouth from neighbors, friends, or family who’ve had similar work done is still the most reliable source. Ask them specifically about communication, whether the final cost matched the estimate, and how the contractor handled problems.

Local building supply stores like lumber yards and tile showrooms often know which contractors are active in your area and pay their bills on time. That’s a surprisingly useful signal of financial stability.

Where to Find Contractor Candidates

• Personal referrals from neighbors, friends, or family with recent project experience
• Local building supply stores that know which GCs are active and reputable
• Houzz, Angi (formerly Angie’s List), and HomeAdvisor for verified reviews and project photos
• National Association of the Remodeling Industry (NARI) and National Association of Home Builders (NAHB) contractor directories
• Your local building department — ask which contractors regularly pull permits and pass inspections

How Do You Review a Contractor’s Past Work?

Quick Answer: Ask for three references from projects completed in the last two years that match your project type. Call every reference. Ask about timeline, budget accuracy, communication, and how problems were handled. If possible, visit a completed job site in person.

References are meaningless if you don’t use them. Most homeowners ask for references and never call. The ones who call and ask real questions learn the most.

Don’t just ask “Was the work good?” Ask harder questions: Did the project finish on time? Was the final cost within 10% of the original quote? How did the contractor respond when something went wrong? Would you hire them again for a larger project?

Questions to Ask Contractor References

• What was the original project budget, and what was the final cost?
• Did the project finish on time? If not, why?
• How did the contractor communicate during the project?
• Were there any disputes? How were they resolved?
• Did workers show up consistently and keep the site clean?
• Did the contractor pull the required permits?
• Would you hire this contractor again?

How to Evaluate Portfolio Photos and Online Reviews

Photos can be borrowed from other contractors or manufacturers. Look for photos that include consistent branding (their truck, their crew shirts) or ask them to show you the project address so you can verify it. On review platforms, read the one and two-star reviews carefully. They often reveal patterns — missed deadlines, poor communication, billing disputes — that a handful of five-star reviews can’t cancel out.

How Many Quotes Should You Get for a Contractor Project?

Quick Answer: Get at least three written quotes for any project over $5,000. Three quotes give you a market rate baseline, reveal pricing outliers, and help you compare scope details across bids. Never accept a verbal quote for major work.

Multiple quotes do more than protect your wallet. They force you to define your project clearly, which leads to better communication with whoever you hire. Each contractor will also bring different ideas about how to approach the work.

When comparing quotes, don’t sort by price first. Sort by scope. A quote that’s $3,000 lower might exclude items the other two include. An apples-to-apples comparison requires identical scope documents.

What Contract Terms Should You Look for Before Signing?

Quick Answer: A solid contractor contract includes a detailed scope of work, material specifications, a milestone-based payment schedule, a change order process, a project timeline, lien waiver terms, and a dispute resolution clause. Never sign a contract missing these elements.

The contract is your legal protection if anything goes wrong. A handshake deal or a one-paragraph agreement is not enough for any project over a few hundred dollars. The more detailed the contract, the less room there is for dispute.

Essential Contract Terms for Hiring a General Contractor

• Scope of work: Every task, trade, and deliverable written out in plain language
• Material specifications: Brand names, model numbers, grades, and quantities where applicable
• Payment schedule: Tied to completion milestones, not calendar dates
• Change order clause: Any change to scope must be written and signed before work begins
• Project timeline: Specific start date, milestone dates, and substantial completion date
• Lien waiver provision: Contractor provides signed waivers from subcontractors as they are paid
• Warranty terms: Length of workmanship warranty (typically 1 year minimum) and what it covers
• Dispute resolution: Agreed process for handling disagreements (mediation before litigation)
• Termination clause: Conditions under which either party can exit the contract

What Is a Mechanics Lien and Why Should You Care?

A mechanics lien is a legal claim a subcontractor or supplier can place on your property if they aren’t paid. This can happen even if you paid your GC in full. If your contractor doesn’t pay their subcontractors, those subs can lien your home. A lien waiver clause in your contract — requiring the GC to provide signed waivers as payments are made — protects you from this risk.

How Should a Contractor Payment Schedule Be Structured?

A fair payment schedule ties payments to project milestones, not time. A common structure for a mid-size project: 10% at contract signing, 25% when materials are delivered, 25% at rough-in inspection (framing, plumbing, electrical before walls close), 25% at substantial completion, and 15% at final walkthrough and punch list sign-off.

Never pay more than 30% before work begins. If a contractor demands 50% or more upfront, that’s a serious warning sign.

What Are the Red Flags of an Unreliable Contractor?

Quick Answer: Walk away from any contractor who demands large cash payments upfront, has no verifiable license or insurance, refuses to provide a written contract, pressures you to decide immediately, or shows up unsolicited after a storm. These patterns signal financial instability, fraud risk, or unlicensed operation.

Red flags are not negotiating points. They are patterns that repeat across projects. A contractor who pressures you this week will pressure you when something goes wrong in month two.

How Do You Manage a Contractor Once the Project Starts?

Quick Answer: Stay involved without micromanaging. Schedule weekly check-ins, document every change in writing, make payments only when milestones are completed, and do a walkthrough before each payment. Keep a project log of dates, decisions, and communications throughout the job.

Hiring a good contractor is step one. Managing the relationship well keeps the project on track. Most problems happen because of poor communication, not poor craftsmanship.

How to Handle Change Orders During a Project

A change order is a written document that modifies the original contract scope, cost, or timeline. It must be signed by both parties before new work begins. Never allow verbal approvals for changes. Even a simple “while you’re at it” conversation can turn into a $2,000 dispute if it’s not documented.

What to Do If a Contractor Disputes Arise Mid-Project

Start by reviewing your contract. Most disputes come back to unclear scope language or undocumented changes. If direct conversation doesn’t resolve it, request formal mediation before pursuing legal action. Many contractor disputes can be settled in mediation for far less than the cost of a lawsuit.

If the contractor abandons the project or refuses to complete work after receiving payment, file a complaint with your state contractor licensing board. That complaint becomes part of their public record.

Final Walkthrough and Punch List Best Practices

Before your final payment, do a thorough walkthrough with the contractor. A punch list is a written record of all remaining items — touch-ups, fixes, and incomplete work — that must be finished before the job is closed out. Hold the final payment (typically 10-15% of the total contract) until every item on the punch list is complete and you are satisfied with the result.

Frequently Asked Questions

How long does it take to find and hire a reliable general contractor?

Plan on two to four weeks from first contact to signed contract for most residential projects. This gives you time to collect referrals, verify licenses and insurance, get three or more quotes, and review the contract carefully. Rushing this process is one of the most common ways homeowners end up with the wrong contractor.

Is it safe to hire a contractor from an online platform like Angi or Houzz?

Online platforms are a good starting point, not a final vetting step. These platforms verify some credentials, but their vetting depth varies. Always verify the contractor’s license and insurance yourself through your state board, regardless of where you found them.

What percentage of the total project cost should you pay upfront?

A fair upfront deposit is typically 10 to 20 percent of the total project cost. Some states cap contractor deposits by law. Never pay more than 30 percent before work begins, and tie all remaining payments to completed milestones rather than calendar dates.

Can a homeowner pull their own permits instead of the contractor?

In most states, homeowners can pull permits for work done on their own primary residence. However, if a contractor pulls the permit, they take legal responsibility for the work meeting code. If you pull it, you take that responsibility yourself. For complex projects, let the licensed contractor pull their own permits.

What is a surety bond and do contractors need one?

A surety bond is a type of financial guarantee that protects you if a contractor fails to complete the job or causes damage they don’t pay for. It’s separate from insurance. Many states require contractors to be bonded as part of licensing. Ask if your contractor is bonded and verify it through your state licensing board.

What happens if a contractor walks off the job before it’s finished?

First, document everything — photos, communications, payment records. Then send a written notice of default and give the contractor a deadline to respond. If they don’t return, file a complaint with your state licensing board and consult a construction attorney. Your contract’s termination clause and payment schedule will determine your legal options and how much you may recover.
