Hiring contractors for your home renovation can be both exciting and nerve-wracking. On one hand, you’re eager to bring your dream space to life—whether it’s a kitchen remodel, basement transformation, or full-scale home upgrade. On the other, you’re trusting someone with your home, money, and timeline. While most contractors are skilled professionals, there are unfortunately many who fall short on communication, integrity, or execution.
At Cozy Casa, we’ve worked with numerous clients across Ontario who came to us after being burned by unprofessional or dishonest contractors. Over time, we’ve learned how to spot the warning signs early—and now, we want to share that knowledge with you. In this blog, we’ll break down the top 5 red flags to watch out for when dealing with contractors, so you can protect yourself, your home, and your investment.
Whether you’re hiring a general contractor for a major renovation or working with a remodeling specialist for a smaller project, these red flags should never be ignored. Being informed is the best way to avoid financial and emotional setbacks—and to make sure your renovation ends with a result you’ll love.
Why It’s Important to Screen Contractors Carefully
Your contractor plays a central role in every aspect of the renovation process: planning, permits, scheduling, labor coordination, material sourcing, budgeting, and quality control. A great contractor can make the process smooth and efficient. But a bad contractor? They can cause delays, rack up hidden fees, use low-quality materials, ignore building codes, and leave you with unfinished or unsafe work.
Unfortunately, not every contractor is upfront or qualified. And in an industry with relatively low barriers to entry, it’s easy for inexperienced or unlicensed individuals to present themselves as professionals. That’s why screening is essential. The time you spend vetting a contractor can save you weeks—or even months—of frustration.
So, what should you be watching for?
Red Flag #1 – No License or Proof of Insurance
The most fundamental requirement for any contractor in Ontario is proper licensing and insurance. A licensed contractor has met the legal and professional qualifications to perform renovation work. Insurance—especially liability insurance and workers’ compensation—protects you from lawsuits or out-of-pocket costs if something goes wrong.
If a contractor is unable—or unwilling—to show you proof of licensing and insurance, stop right there. This is one of the clearest signs of an unprofessional operator. No matter how great their quote is, working with an unlicensed contractor puts your home and finances at risk. They may not be familiar with building codes or permit processes, which means their work could be illegal, unsafe, or both.
Cozy Casa Tip: Ask to see their Ontario contractor license and copies of insurance documents. Make sure coverage is active for the full duration of your project.
Red Flag #2 – Vague or Unwritten Estimates
Trustworthy contractors are clear, detailed, and professional in their pricing. If someone gives you a vague verbal estimate, avoids providing line-by-line breakdowns, or refuses to put anything in writing, that’s a major red flag.
Without a detailed written estimate, you’re leaving the door open for miscommunication, unexpected costs, or price increases halfway through your project. The best contractors will provide a formal quote that outlines labor costs, material expenses, permit fees, subcontractor charges, and a reasonable contingency for unexpected issues.
Beware of contractors who push for a quick handshake agreement or try to convince you that “they’ll figure it out as they go.” That’s not a plan—it’s a setup for cost overruns.
Cozy Casa Tip: Always get a signed written estimate and contract that details the full project scope. We offer transparent quotes with no hidden fees, so our clients are never surprised.
Red Flag #3 – Asking for Large Payments Upfront
While it’s standard for contractors to ask for a deposit before starting work, be wary of anyone requesting 50% or more upfront, or worse, the entire payment before the job even begins. Legitimate contractors generally request 10–20% upfront, with additional payments tied to specific milestones during the project.
Excessive upfront payment is a common tactic used by scam artists who either disappear with the money or do the bare minimum and then stop showing up. In other cases, it’s simply a sign of financial instability—if a contractor doesn’t have the cash flow to start the job without a large deposit, they might not be running a healthy or sustainable business.
Cozy Casa Tip: Never pay in full until the job is complete and you’ve inspected the work. Our payment structures are milestone-based and clearly stated in your agreement.
Red Flag #4 – No References or Poor Online Reviews
Reputation matters. Contractors who do great work are usually proud to show it off. If your contractor can’t provide recent references, or if they seem evasive when you ask for client testimonials or project photos, it could mean they have something to hide.
Also, take the time to check online reviews across platforms like Google, HomeStars, Houzz, and Facebook. While one or two negative comments aren’t necessarily a deal-breaker, recurring complaints about the same issues—like poor communication, delays, or shoddy work—should not be ignored.
On the flip side, a strong portfolio and consistent positive feedback are excellent indicators of professionalism and reliability.
Cozy Casa Tip: You can view our testimonials and completed projects on our Client Reviews page, and we’re always happy to provide references upon request.
Red Flag #5 – No Clear Timeline or Project Plan
When dealing with contractors, another huge red flag is the lack of a clear timeline and structured project plan. If your contractor can’t provide approximate start and end dates, or if they’re vague about how long the project will take, it may indicate poor organization—or worse, overbooking or inexperience.
A reputable contractor will give you a rough timeline from the start and break it down into phases: design, permits, demolition, construction, inspections, and finishing. They’ll also communicate proactively about potential delays, material backorders, and weather contingencies.
A project without a schedule is like a ship without a compass. Delays, cost increases, and constant rescheduling can derail your renovation and frustrate everyone involved.
Cozy Casa Tip: Our project managers provide weekly updates and progress check-ins, so you’re always informed about what’s happening in your home.
Bonus Red Flags to Keep an Eye On
While the five red flags above are the most critical, a few other behaviors should make you think twice:
- They won’t pull permits. If a contractor tells you permits aren’t needed for structural, plumbing, or electrical work, they’re either uninformed or trying to cut corners.
- They show up late or miss appointments. If a contractor is unreliable before the job starts, it’s unlikely they’ll improve during the build.
- They discourage you from asking questions. You deserve to be informed and involved. A contractor who acts annoyed or evasive when questioned probably lacks transparency.
- They offer “cash discounts.” This often means they’re avoiding taxes, and your project won’t be documented or warrantied.

FAQs: Red Flags and Tips When Hiring Contractors
- What’s the biggest red flag to watch for when hiring a contractor?
The absence of a valid license or insurance is the most serious red flag. It puts your home and finances at legal risk. - Is it normal to pay a contractor before the project starts?
Yes, but only a small deposit (typically 10–20%). Never pay the full amount upfront. - Can I trust online reviews when hiring a contractor?
Yes, they’re a valuable resource—but verify with references and speak directly to past clients if possible. - How can I protect myself from contractor scams?
Use written contracts, request proper documentation, verify reviews, and avoid paying large sums upfront. - What should a contractor’s estimate include?
It should itemize labor, materials, permits, subcontractors, timelines, and payment structure. - Should I hire a contractor who offers a “cash-only” deal?
No. This usually means they’re operating off the books, which means no warranty, no permits, and no accountability. - What do I do if my contractor is missing deadlines?
Address it in writing, refer to the contract, and if needed, pause payment until the issue is resolved. - How important is a written contract?
It’s essential. Without one, you have no legal protection if something goes wrong. - What should I do if I’ve already hired a bad contractor?
Stop work, document issues, and seek legal or third-party dispute resolution support. Cozy Casa also helps homeowners recover stalled projects. - Why is Cozy Casa a trusted renovation partner?
