How to choose a basement contractor: a vetting checklist

Pick the contractor who passes four checks before you compare prices. You look up their license with your state or county and it's active.¹ They show you proof of insurance.¹ They agree in writing to pull the permit.¹ Their written contract lists the scope, the price and the start and completion dates.¹ Walk away from anyone who asks you to get the permit, wants the whole price up front or pushes you to sign today.¹

TL;DR

• Check the license with your state or county and get proof of insurance before you sign anything.¹
• Ask each contractor to pull the permit. The FTC lists a request that you get the permit as a scam tactic, so that request ends the conversation.¹
• Tie payments to finished stages and hold the final payment until the work is done and you're happy with it. Some states cap the down payment.¹
• Compare written quotes line by line and ask what each one includes, such as cleanup and permits.²³
• Keep a handyman to jobs like paint and trim. Plumbing and electrical work call for a pro.³²

How do I choose a basement contractor?

Choose a basement contractor in five steps. Build a shortlist from people you trust. Verify each license and insurance policy yourself. Ask each one to pull the permit. Get written, itemized estimates from several contractors. Then sign only a contract that lists the scope, dates and price, with payments tied to finished work.¹²

The order matters. Price comes last because a cheap quote from a contractor who fails the first four steps is money at risk.

1. Build a shortlist

Start with people you know who have finished a basement. Ask what went wrong and whether they'd hire the same contractor again. Then check each name with your local Home Builders Association and your state consumer protection office for complaints. Search the company name online with words like "scam", "review" and "complaint".¹

Ask how much of their work is basements. A basement finish needs framing, electrical, plumbing and moisture-control skills in one below-grade space.³ A contractor who mostly builds decks or kitchens may never have dealt with basement moisture or low ceilings.

2. Verify the license

Look the license up yourself with your state or county.¹ Trust that record over a number printed on a truck or a business card. Confirm the license is active and issued to the company you're hiring. Licensing rules vary by state and city, so ask your state or city licensing office what license a basement finish needs where you live.

While you're at it, search the business name in your state's business registry to confirm it's registered. In Colorado and Georgia the Secretary of State runs that registry.

3. Verify the insurance

Ask for proof of insurance.¹ HomeGuide's hiring checklist also asks you to confirm the contractor is licensed, insured and bonded.² Ask to see two policies. General liability covers damage the work causes to your property. Workers' compensation covers injuries to the contractor's workers.

Ask the contractor to have their insurer send the certificate of insurance directly to you. A copy the contractor hands you proves less. Do the same check for any subcontractor who isn't covered under the contractor's own policy.

4. Settle the permit question

Ask one direct question: "Will you pull all required permits and book the inspections?" The answer should be yes, in writing. A contractor who asks you to get the permit is using a tactic the FTC lists as a sign of a scam.¹ HomeGuide says a basement finish needs a permit before work begins.² Angi ties permits and inspections to making sure the new space meets code.³ Permit rules are set locally, so your building department has the final word.

Permit history tells you more than a promise does. Ask for the permit numbers from two recent basement jobs. A contractor who pulls permits as routine will have them to hand. Ask your local building department how to confirm them.

5. Compare written quotes and sign a complete contract

Get several written estimates. Each one should describe the work and list the materials, the completion date and the price. Judge each bid by what it covers, and ask each contractor to explain any big gap between quotes.¹

The checklist on one page

The license, insurance, permit, estimate, contract and payment checks follow the FTC's home improvement advice.¹ The business registration check, the insurer-sent certificate and the site visit are extra precautions that take little time.

What are the red flags of a bad renovation contractor?

The clearest red flags are a request that you pull the permit, a demand for full or cash payment up front and pressure to decide on the spot. The FTC lists all three as scam tactics. Door-to-door pitches, "leftover materials" and a lender the contractor knows are on the same list.¹

Any one of those three ends the conversation. The warning signs that follow call for judgment. Weigh each one against how the contractor answers when you raise it.

Before the estimate

• They knock on your door. Scammers often say they're "in the area" or have materials left over from another job.¹
• They quote a firm price without seeing the basement. A real price depends on your space, so a number given before anyone measures is a guess.
• They dodge questions. Vague answers about insurance, or about problems outside their scope, should give you pause.

In the quote and contract

• The quote is verbal only. The FTC and HomeGuide both tell you to get the estimate in writing.¹²
• They suggest skipping the permit to save time or money. The inspections that come with a permit are how the work gets checked against code.³
• The bid is far below the others. HomeGuide warns that the lowest quotes usually result in low-quality work.² Ask the contractor to explain the gap.¹
• The warranty isn't in writing. HomeGuide lists "Do you offer a warranty?" among the questions to ask.² If the answer is yes, get the terms into the contract.
• They plan to finish over a problem. An honest contractor tells you when your basement needs work they don't do, such as waterproofing, a sump pump, radon mitigation or foundation repair. Those jobs go to the right specialist before any framing starts.

Around money

• They want everything up front or cash only.¹
• They offer to arrange a loan through a lender they know. The FTC describes a scam where homeowners end up in a high-interest home equity loan while the work goes unfinished. Compare loan terms elsewhere before you agree to any financing.¹

After work starts

• They bring papers to sign mid-job. The FTC warns about contractors who ask you to sign documents once work has begun, sometimes blank and sometimes in a rush. Read every page first. Never sign a document with blank spaces.¹

What should the contract and payment schedule say?

The contract should name the contractor with their address, phone number and license number. It should give start and completion dates, the scope, the price and every promise made in conversation. It should state your right to cancel within three business days if you sign at home. Every blank space should be filled in.¹

The three-day cancellation right applies when you sign in your home or anywhere other than the seller's permanent place of business. Contract rules vary by state. Ask for a written contract even where your state doesn't require one.¹

Beyond the FTC's list, get written answers to these questions:

• What's included in the scope, and what's excluded?
• How are change orders priced and approved?
• Which milestones trigger each payment?
• What does the workmanship warranty cover, and for how long?
• Who are the subcontractors, and are they licensed and insured?
• What happens if the job runs past the estimated finish date?

How payments should be staged

Pay in stages tied to finished work. For example, a schedule might set a modest deposit at signing, a payment when framing is done, another when rough-in work passes inspection and the last at completion. A staged schedule keeps you from paying ahead of the work.

Some states limit how much a contractor can ask as a down payment. Your state or local consumer agency can tell you the rule where you live. Hold the final payment until the work is done and you're happy with it.¹

Can a handyman finish a basement?

A handyman can take on the simple finish tasks that homeowners often do themselves, such as paint and trim.³ The core of a basement finish is framing, wiring, plumbing and HVAC.² Angi says to hire an electrician for new outlets and light fixtures and a plumber to extend pipes for a bathroom or kitchenette.³ The job also needs permits and inspections.³ Trade licensing rules vary by state and city, so check what applies where you live.

Cost guides draw the same line. Angi suggests leaving the technical work to pros, with demolition (where no hazardous materials are present), trim and finishing work as tasks a handy homeowner can take on.³ HomeGuide notes that professionals recommend hiring help for plumbing and electrical work. It adds that some homeowners finish part of the basement themselves and hire contractors for the rest.²

A split job can work. Hire a licensed contractor for the permitted scope and use a handyman for paint and trim after the final inspection. Write the split into the contract so both sides know who owns which work. If a handyman offers to run new circuits or plumbing without a permit, treat it as the same red flag as any contractor who skips permits.

Before you split the work, see what a full basement finishing job covers, from framing and insulation to flooring and ceilings.

What should you ask a basement contractor?

Ask questions that make the contractor show proof. How much of your work is basements? Will you pull the permit and book the inspections? Who are your subcontractors, and are they licensed and insured? What does the quote exclude? How are change orders priced and approved? What does the warranty cover, and for how long?²

Listen for detail in the answers. A good contractor names the trades, the inspections and the exclusions without being pushed.

A few more questions separate careful contractors from the rest:

• "Will you walk the basement with me and tell me what you see?" Stains at the base of walls, white mineral deposits (efflorescence), a musty smell and foundation cracks can all point to moisture. A careful contractor points these out before talking about finishes.
• "Tell me about a job where you found moisture halfway through." The answer shows how they handle a surprise and how they tell the owner about it.
• "What happens if you find a problem outside your scope?" You want a plain answer that they'll tell you and stop.
• "Does this estimate include materials, labor, delivery and cleanup?"²
• "What unexpected costs usually come up on a job like mine?"²
• "How long will it take?" HomeGuide puts a basement finish at 4 to 16 weeks depending on rooms, size and scope.² A timeline far outside that range needs an explanation.
• "Can I see photos of past basement projects and talk to those owners?"²

What should you not say to a contractor?

Watch for any sentence that hands away one of your protections. The riskiest ones offer to get the permit yourself, pay everything now or in cash, skip the paperwork or sign on the first visit. Each one gives up a protection the FTC tells homeowners to keep, so say the protective version.¹

The first five rows come from the FTC's guidance.¹

What does a good basement quote show?

A good quote is written and itemized. It describes the work, names the materials and gives a completion date and price.¹ Ask whether it includes materials, labor, delivery and cleanup, and whether any subcontractors will work on the job.² With that detail you can compare quotes line by line and see why one total is lower.

Price gaps between quotes are common, and the FTC says to ask for an explanation when the gap is big.¹ A lower total that leaves out permits, cleanup or some materials isn't lower once you add those back.

Permits are the line most worth checking, and the cost guides disagree on the size of it. HomeGuide puts a basement finishing permit at $200 to $1,000, or 1% to 2% of total costs in some cities.² Angi puts permits at about $1,200 to $2,000 of the total and also notes that some municipalities charge 1% to 2% of the project.³ Your building department's fee schedule is the real number. Until you have it, use Angi's higher range when you test whether a quote without permits is really cheaper. Underestimating is the more expensive mistake.

Labor share is a rough sense check. Angi puts professional labor at about 20% of the total.³ HomeGuide puts labor at 20% to 40% and materials at 60% to 80% of total costs.² A quote far outside those shares deserves a question.

The cost to finish a basement varies with where you live.³ Compare your quotes against published ranges for basement remodeling costs in Denver, Colorado Springs basement costs and what a Fort Collins basement costs. In Georgia, check Atlanta basement remodeling costs.

How does a matched contractor get vetted?

Basement Remodeling Co. screens a contractor before you meet them, using six checks. Each matched contractor must be licensed where the state or city requires it, insured, well reviewed and a basement specialist. They must also give written, itemized quotes and pull permits. You still make the final call on price and fit.

When you fill in the free quote form, the request goes to one vetted, independent, licensed basement contractor for your metro. Nobody else receives it. The contractor books a free on-site estimate, measures, checks moisture and ceiling height and talks through layout. You get a written, itemized quote, and nothing starts until you sign. Your contractor pulls the permit and books the inspections.

Run the license and insurance checks yourself anyway. The contract is between you and the contractor, and your own lookup takes the guesswork out of it. Basement Remodeling Co. works in metro Atlanta, Denver, Colorado Springs and Fort Collins. When you're ready, get matched with a vetted basement contractor near you. If your basement is already finished and needs rework, start with how basement remodeling differs from a first finish.
