How to Avoid Contractor Scams Before Renovating

A renovation can look finished on the surface while unsafe wiring, loose plumbing, and unapproved work sit behind the walls. That is why hiring the right contractor matters as much as choosing tile, paint, or cabinets.

A low estimate and a friendly sales pitch can feel reassuring, especially when you are eager to get started. However, a contractor who lacks the right license, insurance, permits, or written agreement can turn a home project into an expensive repair job.

Why Contractor Problems Can Cost You Twice

Home renovations involve serious money. Homeowners spent about $472 billion on renovations in the prior year, while more than 54% of homeowners took on some kind of home improvement project.

That much spending attracts legitimate, skilled professionals. It also attracts people who see a chance to take deposits, cut corners, and disappear before the consequences catch up with them. That's exactly why I started TrustDale, to give consumers a way to cut through all the smoke and mirrors and know they're hiring a truly skilled contractor who will do great work for a fair price.

When that doesn't happen, the damage is often hidden until a later inspection, a leak, or a renovation problem forces someone to open a wall. TrustDALE Senior Producer Marnie Zambri described the risk plainly: "You don't know until it's too late." A room may look fine at first, yet faulty work behind drywall can require demolition and a complete redo.

Andy Rose, a realtor who renovates older homes for resale, experienced that problem firsthand. After finding a contractor through online networking, Rose discovered dangerous electrical work, plumbing connections that could be pulled apart by hand, and other defects throughout the property.

An electrician later told him the work was a fire hazard. The electrical wires had not been properly pulled, and open splices were left inside the walls. The plumbing was also improperly assembled because the connections lacked the cement needed to hold them securely.

The contractor had not pulled permits. Worse, Rose learned the person he hired was not the licensed general contractor he claimed to be. According to Rose, the contractor had used someone else's license.

"I've had to pull out $20,000 in personal savings. I've had to pull out $34,000 in IRA money to keep this thing afloat for over a year."

Rose's experience shows why a bargain bid can become the most expensive option. Once unsafe work is uncovered, the homeowner may have to pay a qualified contractor to rewire, replumb, repaint, replace drywall, and repair work that should have been done correctly the first time.

Vet a Contractor Before You Sign Anything

Personality matters in a working relationship, but it does not prove that someone can legally and safely renovate your home. A polished social media page, a nice-looking truck, or a convincing sales pitch should never take the place of verification.

Julian Muñoz of TrustDALE Certified Partner JMR Home Services put the first step simply: "Do your research, do your homework." That research should happen before the contractor begins work, pulls a permit, or receives a deposit.

Start by confirming that the company holds the proper state-issued contractor license for the type of work being proposed. A business license is not the same as a contractor license. General contracting, electrical work, plumbing, and HVAC work can each require separate credentials.

Ask for the contractor's license number, then search your state's licensing database using the company name and number. The details should match. If the person selling you the job is using another contractor's license, or cannot tell you who holds the license, treat that as a serious warning sign.

Insurance is equally important. A contractor can hand you a certificate of insurance that is outdated, incomplete, or not connected to the work being done. As a Consumer Investigator, I always advise homeowners not to stop at the paperwork.

Use this verification process before hiring a contractor:

• Confirm the contractor's state license and make sure it matches the company and person responsible for the work.
• Ask for the insurance carrier and agent, then call the agent to confirm that liability coverage is active.
• Ask whether you can be listed as an additional insured for the project when appropriate.
• Find out whether workers' compensation coverage applies to the people who will be working at your home.
• Request 20 recent references, then call at least three instead of just relying on a list of names.

If a worker gets injured at your home and the contractor lacks proper coverage, the homeowner may face legal and financial exposure. As Muñoz explained, the safest course is to verify that the company is properly insured before work begins.

Red Flags That Should End the Conversation

High-pressure sales tactics are one of the clearest danger signs. Be cautious if a contractor says you must sign immediately or claims the price will double unless you agree that day.

Muñoz called that approach a red flag. A reputable contractor can explain the estimate, give you time to review it, and answer questions about the scope of work.

Large cash deposits should also make you pause. Contractors need funds to manage permits, scheduling, and materials, but a request for a large amount of money before meaningful work begins can leave you with little protection if the contractor vanishes.

Another major warning sign is a contractor who asks you to pull the building permit for work they are supposed to manage. As I said in the podcast: "You're paying them. Let them do it."

Permitting rules vary by city and county, but permit applications often ask who will perform the work and require contractor license information. A contractor who wants the homeowner to take responsibility for the permit may not have the credentials required to do the job. Homeowners can act as their own general contractor in some situations, but that role carries responsibilities for scheduling, oversight, trade licensing, and compliance.

Put the Entire Project in a Detailed Written Contract

"A handshake is not a contract!" - Dale Cardwell, Consumer Investigator

A handshake can start a conversation. It cannot protect your money, define the work, or settle a dispute months later.

A handshake is not a contract!  A written agreement creates a shared record of what the contractor promised, what you agreed to pay, and how both sides will handle changes.

The most important part of the agreement is the scope of work. It should explain what the contractor will do, where the work will happen, what materials are included, and what the finished project should look like. For a bathroom renovation, that may include shower dimensions, tile choices, plumbing fixtures, cabinetry, paint, lighting, demolition, and disposal.

Vague wording creates room for conflict. A contract that says "renovate bathroom" does not answer important questions about who supplies the fixtures, what grade of materials will be used, or whether the contractor will remove debris each day.

Your agreement should clearly address the following:

• The detailed scope of work, including materials, finishes, measurements, and labor.
• The project schedule, including expected start date, major milestones, and conditions that could delay the work.
• The payment schedule and the amount due at each stage.
• The process for change orders, including written approval before extra work begins.
• Cleanup duties, permit responsibilities, and who will schedule inspections.
• Workmanship warranty terms and manufacturer warranties for materials.

A change order deserves special attention. Renovations often reveal surprises behind walls or under floors. Sometimes a homeowner also changes a fixture or finish after work has started. Those changes may be reasonable, but they should be documented in writing with the added cost, timeline impact, and approval date.

A contractor should not perform expensive extra work based on a casual conversation. Likewise, a homeowner should not assume a verbal request is included at no charge.

Separate Workmanship Warranties From Product Warranties

A manufacturer warranty covers the product itself. For example, a paint, faucet, appliance, or flooring manufacturer may offer a warranty for a defect in its product.

A workmanship warranty covers the contractor's labor. If tile comes loose, paint peels due to poor preparation, or a connection leaks because the installation was faulty, the contractor's workmanship warranty should explain how long the company will stand behind the work.

Muñoz said JMR Home Services provides a one-year warranty because the company performs many types of work. The exact length and coverage may differ among contractors, but the key point is the same: get warranty terms in writing and know who is responsible for each part of the project.

A contract should tell you what happens when something goes wrong, not leave you guessing after the check has cleared.

Use a Payment Schedule That Follows Completed Work

A fair payment schedule should match real progress at the job site. You should not pay for major portions of a project before the contractor has completed and verified comparable work.

Muñoz described JMR's approach as a modest initial deposit, followed by an additional amount to break ground and then draws based on completed work. He emphasized that the company does not ask for more than the value of the work already performed.

That principle protects both sides. The contractor receives funds as the project moves forward, while the homeowner avoids handing over too much money before seeing results.

The exact numbers will vary based on the size of the job, local rules, material needs, and project schedule. Still, you should question a contractor who demands a large cash payment up front, pushes for payment before a phase is complete, or cannot explain how payments connect to project milestones.

Pay by a method that creates a record. Keep copies of the signed contract, change orders, invoices, proof of payment, inspection reports, photographs, and messages with the contractor. If a disagreement develops, that paper trail may matter as much as the original agreement.

Cash can make disputes harder to prove. It also gives a dishonest contractor an easier way to disappear without a trace.

Plan Materials and Communication Before Demolition Starts

A realistic renovation timeline begins before workers arrive. Homeowners often want work to start immediately, but moving too fast can create delays if fixtures, finishes, and materials have not been selected and ordered.

Muñoz used a bathroom remodel to explain the problem. A contractor may demolish the shower and prepare for rough plumbing, only to find that the homeowner has not yet ordered the shower valve. If that particular fixture takes three weeks to arrive, the bathroom can sit unfinished while the project waits.

"Planning is very important," Muñoz said. Selecting finishes ahead of time gives the contractor the information needed to schedule labor and prevents avoidable gaps between phases.

Before the start date, confirm the availability of items that can hold up construction, such as:

• Plumbing fixtures, shower valves, tubs, and specialty drains.
• Cabinets, countertops, flooring, tile, and lighting.
• Appliances, custom doors, windows, and special-order hardware.

Communication should also be documented. A contractor may use a client portal or customer relationship management system to share schedules, approvals, updates, photographs, and change orders. That type of system can be useful because it keeps a written history of decisions.

Still, technology should not replace access to a real person. Muñoz said a client portal is, "just a tool to make the experience better," while homeowners should still be able to call or text the project manager when questions come up.

Know Who Will Be Working in Your Home

Many general contractors use subcontractors for plumbing, electrical, HVAC, roofing, drywall, and other specialized work. That is common, but you should ask who will be on the property and who is responsible for their work.

A full background investigation of every worker is not standard procedure across the industry. However, a professional general contractor should know the subcontractors they hire, have an established relationship with them, and confirm that licensed trades hold the required credentials.

Muñoz explained that JMR requires plumbers, electricians, and HVAC contractors to be licensed. Those trades may also need to pull permits under the broader project permit.

References are another useful check, but only if you investigate them. Ask for five to seven recent references when possible. Then call them. Ask whether the contractor stayed on schedule, handled changes fairly, kept the site clean, honored the warranty, and communicated clearly.

If you can, drive by completed projects with the owner's permission or view photos that show work in progress as well as the final result. A contractor's best portfolio should include more than polished after photos.

Use Consumer Protection Resources When You Need Them

Homeowners should not have to choose between moving forward blindly and becoming construction experts. A careful hiring process, detailed paperwork, and verified credentials offer meaningful protection before the first wall comes down.

For homeowners in the Atlanta area, TrustDALE's certified service provider directory lists companies that have passed my seven-point investigative process. TrustDALE also backs eligible work with our Make It Right Guarantee of up to $10,000.

That guarantee does not replace your responsibility to read the contract, ask questions, and verify the basics. It does provide an added layer of recourse when a qualifying job does not meet expectations.

Protect Your Home Before the Work Begins

The safest renovation starts with verification, not a deposit. Check the contractor's license and insurance, speak with real references, review the permit plan, and demand a written agreement that leaves little room for confusion.

A cheap estimate can be tempting, but unsafe work and incomplete projects can force you to pay twice. Asking the right questions before hiring can protect your home, your savings, and your peace of mind. Slow down. Do your homework BEFORE you commit your money.
