5 Red Flags to Watch for When Hiring a Contractor
A Homeowner's Guide to Avoiding Costly Mistakes
Hiring the wrong contractor can lead to unexpected costs, unfinished work, disputes, and major frustration. While these are not the only warning signs homeowners should watch for, they are some of the most common issues that can create problems before, during, or after a project.
Use this guide to help identify potential red flags, ask better questions, and make more informed hiring decisions before signing an agreement or starting work.
RED FLAG #1: Operating Under the Radar
What it Looks Like ...
- Not registered with the state as a business.
- No contractor license when required.
- No proof of insurance / Certificate of Insurance (COI).
- Being told they only accept cash.
- Little to no online presence, reviews, or verifiable past work.
Why It Matters
Registered businesses must list a real address with the state, making them traceable. If they are uninsured, the homeowner could be liable for injuries or damages.
Someone operating under the radar may also be difficult to track down if problems arise, making it harder to locate or hold them responsible if something goes wrong.
RED FLAG #2: High Pressure Sales Tactics
What it Looks Like ...
- Being asked to sign something before you're ready.
- Being told the offer is only available if you sign today.
- Being told they can start immediately.
Why It Matters
Being pressured to make a quick decision can keep homeowners from asking questions, checking backgrounds, comparing bids, or reviewing details carefully.
While immediate availability is not always a bad sign, unusually open schedules can sometimes indicate that a contractor has limited experience, inconsistent demand, or underlying business issues
RED FLAG #3: Vague Details in Scope
What it Looks Like ...
- Estimates or agreements not in writing.
- Major materials or finishes left undefined.
- Key details dismissed with "we'll figure that out later."
Why It Matters
Vague, incomplete, or unwritten project details can lead to misunderstandings, unexpected costs, reduced quality, or disputes over what was verbally promised.
Clear written details help homeowners compare bids accurately and hold contractors accountable for the agreed scope of work.
RED FLAG #4: Suspiciously Low Bids
What it Looks Like ...
- An estimate that is far lower than other estimates received.
- Being told they'll use leftover materials from another job to save you money.
- A price that seems too low for the work described.
- An estimate that excludes necessary parts for the job.
Why It Matters
Extremely low bids are not always a bad sign, but pricing that falls far below other estimates may indicate that important costs were overlooked, excluded, and may surface later.
In some cases, contractors might try to raise the price later through change orders, use lower-quality materials, cut corners, or leave out necessary parts of the job to make up for the low price.
RED FLAG #5: Questionable Payment Practices
What it Looks Like ...
- Large upfront payments
- Being asked to pay suppliers directly.
- Being told they only accept cash.
Why It Matters
Reputable contractors typically have established supplier relationships and credit, reducing the need for large upfront payments, if any are needed at all
Large upfront payments can reduce your leverage and increase the risk of losing money if the contractor underperforms or disappears.
