How to Choose a General Contractor — 10 Key Steps

How to choose a general contractor is one of those decisions that looks simple on the surface until you're three months into a renovation with a stranger managing your house. The wrong choice costs you money — sometimes a lot of it — and the right choice makes the difference between a project that finishes on time and one that drags on for a year with a revolving door of subcontractors.

Whether you're hiring for a kitchen remodel, a home addition, or a commercial build-out, the process for finding and vetting a general contractor follows the same basic framework. This guide walks through it step by step — not the generic "get three bids" advice you'll find everywhere, but the specific questions, red flags, and verification steps that actually separate qualified contractors from the ones who'll give you problems.

Step 1: Define Your Project Scope Before You Contact Anyone

You can't evaluate a contractor's bid if you don't know what you're asking them to bid on. Before you make a single call, write down your project scope in as much detail as possible: what work needs to happen, what materials you prefer (or are open to discussing), what your rough budget range is, and what your desired timeline looks like.

You don't need architectural drawings at this stage for most remodels, but you do need clarity on scope. "Remodel the kitchen" isn't enough. "Remove load-bearing wall between kitchen and dining room, install flush beam, relocate plumbing for island, upgrade to 200-amp service, new cabinetry, quartz countertops, tile backsplash" — that's a scope. Contractors can price it, and you can compare bids apples to apples.

If your project requires permits — and most structural work, electrical, plumbing, and additions do — make note of that. A legitimate general contractor will pull permits. A contractor who offers to skip permits to save money is offering you liability and future problems, not savings.

Step 2: Get Referrals from Trusted Sources First

The best contractor leads come from people who've hired them recently and seen the finished result. Ask neighbors, friends, family, and coworkers who've done similar projects. Ask your real estate agent if you have one — they see finished work constantly and often know which contractors hold up over time.

Online sources like Angi, Houzz, and Google Reviews have their place, but treat them as a supplement, not a primary source. Reviews can be gamed, and the projects reviewers describe often differ significantly from yours in scope and complexity. A contractor with 50 glowing reviews for bathroom remodels may be mediocre at structural additions.

Ask for referrals specifically from recent projects — within the last two years ideally. A contractor who was excellent five years ago may have different crew, different management, or different workload today. Recency matters.

Step 3: Verify Licensing and Insurance — Don't Skip This

This is non-negotiable. A licensed general contractor has demonstrated minimum competency to your state's licensing board and carries financial accountability through that license. An unlicensed contractor carries none of that.

Every state has an online licensing lookup tool — usually through the contractor licensing board or state department of business regulation. Look up every contractor's license number before you go further. Confirm the license is active, not expired, not suspended. Confirm the license type matches the work you're hiring for — a contractor licensed for residential work isn't always licensed for commercial, and specialty licenses (electrical, plumbing, HVAC) are separate from the general contractor license.

Insurance verification is equally critical. You need two documents: a certificate of general liability insurance (minimum $1M per occurrence is standard for residential work) and a certificate of workers' compensation insurance. Ask for these documents directly from the contractor's insurance carrier — not a copy the contractor prints themselves, which could be outdated or falsified. Call the carrier if needed to verify coverage is current.

Why does this matter so much? If a worker gets injured on your property and the contractor doesn't carry workers' comp, you may be liable. If the contractor causes property damage and has no liability insurance, you have no recourse outside of a lawsuit. These aren't bureaucratic formalities — they're your financial protection.

Step 4: Interview at Least Three Contractors

Three bids is the floor, not the goal. The point of multiple interviews isn't just price comparison — it's getting a range of perspectives on your project, understanding how different contractors approach problems, and finding someone whose communication style and professionalism match what you need.

During the interview, pay attention to how they respond to your questions. Do they ask clarifying questions about your project, or do they just nod and say they can do it? Do they point out potential complications you hadn't considered? Do they explain their process clearly, or are they vague about how subcontractors are managed?

Ask specifically about the subcontractors they use. Most general contractors don't self-perform all trades — they hire electrical subs, plumbing subs, HVAC subs. Are those subs licensed? Are they regular relationships or one-time hires? How does the GC supervise subcontractor work? These questions reveal how organized the operation is.

Ask what happens when things go wrong — because something always does on any significant project. How do they handle unexpected site conditions? How do change orders work? Who's your primary contact when you have a question or concern? A GC who gives vague answers here is giving you a preview of what working with them will be like mid-project.

Step 5: Get Detailed, Written Bids

A legitimate bid is itemized. It breaks down labor costs, material costs, subcontractor costs, and overhead markup separately — or at minimum shows clear line items by work phase. A bid that just says "complete kitchen remodel: $45,000" gives you no way to evaluate it, compare it to other bids, or understand where cost might shift if scope changes.

When comparing bids, watch for scope differences before price differences. If one contractor's bid is $10,000 lower than the others, it might be because they're not including something the others are — or they're planning to use different materials. Ask each contractor to confirm they've accounted for the same scope items. Matching scope is what makes bid comparison meaningful.

Be wary of the lowest bid. It's not always a red flag — sometimes a contractor is simply more efficient or has lower overhead — but a bid that's dramatically lower than the field usually signals one of three things: missing scope, cheaper materials, or a contractor who'll make it up in change orders. Ask the low bidder specifically what they're doing differently to hit that price.

Step 6: Check References — And Actually Call Them

Every contractor will give you references. That's easy. What matters is what those references actually say when you call them. Most candidates for this list are satisfied customers — contractors don't hand out names of people who had problems. But the conversation still reveals a lot.

Ask specifically: Did the project finish on time? Did it come in on budget, or were there significant change orders? How did the contractor handle problems when they came up? Would you hire them again? If you could change one thing about the experience, what would it be?

Ask to see the finished work if possible. Drive by a completed project. Photos on a website are curated — seeing real work in person tells you more about quality. Pay attention to how finishes align, how trim work looks up close, how consistent the paint is. These details reflect the crew's craftsmanship standard.

Try to reach references who did projects similar to yours in scope and complexity. A contractor who builds beautiful decks may be less experienced at additions. Relevant references matter more than total number of references.

Step 7: Understand the Contract Before You Sign

A solid construction contract protects both you and the contractor. It should include: a detailed scope of work, material specifications, project start and estimated completion dates, payment schedule, change order procedures, dispute resolution process, and warranties on both labor and materials.

Payment schedule is one of the most important contract elements. Never pay more than 10–15% upfront as a deposit — legitimate contractors have credit with suppliers and don't need 50% upfront to start a job. A common structure is: deposit at contract signing, progress payments tied to project milestones, and a retention amount (5–10% of total) held until final completion and punch list sign-off.

Change orders happen on virtually every significant project. The contract should specify that all changes to scope, schedule, or cost require a written change order signed by both parties before work begins. Verbal agreements about changes create disputes — avoid them entirely.

If anything in the contract is vague or you don't understand it, ask for clarification before signing. A contractor who rushes you to sign without answering your questions is a warning sign. This document governs a significant financial relationship — take the time to read it fully.

Step 8: Watch for These Red Flags

Experience teaches certain patterns. These are the warning signs that experienced project owners learn to recognize — sometimes after an expensive mistake:

Asking for large upfront payments. Offering to skip permits. Pressure to decide immediately. Reluctance to provide insurance certificates. Vague references or reluctance to give them at all. No physical business address (just a mobile number). Subcontractors who change frequently. Poor communication during the bidding phase — it only gets worse during a project.

Trust your instincts during the interview process. If a contractor's demeanor makes you uncomfortable, if they're dismissive of your questions, or if their bids are inconsistent across meetings, that's relevant information. You're entering a relationship that may last months — you need someone you can work with.

Step 9: Set Up a Communication Plan

Before work begins, establish how you'll communicate and how frequently. Weekly check-ins, a single point of contact on each side, a preferred method (email, text, a project app like Buildertrend or CoConstruct) — these things prevent the "I didn't know that was happening" problems that create frustration mid-project.

Document everything in writing. When you discuss a change, follow up with an email summarizing the conversation. When the contractor tells you something will happen, ask for it in writing. This isn't about distrust — it's about clarity. Memory is fallible, and construction projects generate hundreds of decisions. Written records protect both parties.

Step 10: Know Your Rights as a Homeowner

Most states have mechanic's lien laws that allow subcontractors and suppliers to place a lien on your property if the general contractor doesn't pay them — even if you paid the GC in full. Ask your contractor for lien releases from major subcontractors and suppliers as work progresses. A "conditional lien release" tied to each payment is standard in professional construction and protects your title to the property.

You also have the right to stop work if the contractor violates the terms of your contract — but do this only with legal counsel if significant money is involved. And keep records of all payments: dates, amounts, checks or bank transfers. You'll need these if disputes arise.

The Right Contractor Makes the Difference

Choosing a general contractor is a skill that gets easier with experience — but most homeowners and small business owners don't have the luxury of hiring 20 contractors before they get good at evaluating them. The framework above compresses what experienced project owners learn the hard way into a systematic process you can run before your first significant project.

The fundamentals don't change: define your scope, verify licensing and insurance, get multiple bids on matching scope, check references honestly, read the contract fully, and set up clear communication from day one. Contractors who resist any of these steps are telling you something important about how they operate.

The vast majority of general contractors are professional, skilled, and genuinely trying to deliver good work. A solid vetting process helps you find them — and helps you avoid the small percentage who won't.
