How to Spot a Bad Contractor: 5 Red Flags to Watch Out for in State College

siteROOST Team • September 29, 2025

Why the Right Contractor Choice Matters


Choosing a contractor for your home's exterior project can feel overwhelming. You’re not just hiring someone to install new siding or build a deck; you're entrusting them with a major investment in your State College property. Unfortunately, not all contractors are created equal. The wrong choice can lead to shoddy work, costly delays, and immense frustration.


At PrimEX Exterior Solutions, we believe in empowering homeowners with the knowledge they need to make the best decision for their home, even if it means choosing someone else. Our goal is to ensure you get a quality job done right. Here are five major red flags to watch out for when vetting contractors in the Central Pennsylvania area.



Red Flag #1: The Door-to-Door Sales Pitch

Be wary of anyone who shows up at your door unannounced, offering an unsolicited deal on a home improvement project. While this might be a legitimate marketing strategy in some industries, it's often a tactic used by storm chasers or unscrupulous companies looking to make a quick buck. These groups typically show up after a major weather event, like a hailstorm or high winds, and pressure you into signing a contract on the spot.


A reputable contractor like PrimEX will have an established business, a physical address, and a good reputation in the community. Their business is built on referrals and a strong online presence, not on aggressive, unexpected sales tactics. They will expect you to do your homework and will gladly provide you with all the information you need.


Red Flag #2: A Very Low-Ball Bid

Everyone loves a good deal, but if a contractor’s bid seems too good to be true, it almost certainly is. A significantly lower price than the other bids you’ve received is a major warning sign. This could mean a few things:


  • They’re using subpar materials: They might be cutting corners by using cheap, low-quality siding, roofing, or windows that won’t last.
  • They're cutting labor costs: This often translates to hiring inexperienced, uncertified labor, leading to poor craftsmanship and a project that takes far longer to complete.
  • Hidden fees: The contractor may have intentionally left key costs out of the initial bid, only to surprise you with them later through change orders and "unexpected" expenses.


A professional contractor will provide a detailed, itemized quote that breaks down the cost of materials, labor, and other fees. Their pricing reflects the value of quality work and durable materials.


Red Flag #3: Demands for Full Payment Upfront

A standard, professional payment schedule for a major exterior project is typically structured in phases. You might pay a down payment to secure materials, a second payment when a key milestone is reached (like the old roof being torn off), and a final payment upon the satisfactory completion of the project.

A contractor who demands cash or a full payment upfront before any work has even begun is a massive red flag. This is a common tactic used by scammers who take the money and disappear, leaving you with no recourse. A legitimate company will have the financial stability to purchase materials and pay their crew without needing 100% of your money upfront.


Red Flag #4: Lack of Proper Licensing and Insurance

This is perhaps the most important red flag to check. Before you sign anything, you must verify that the contractor is properly licensed and insured.


  • Licensing: While Pennsylvania does not have a statewide contractor licensing requirement, many local municipalities and certain types of contractors may require it. Ask for their PA Home Improvement Contractor Registration Number (PA HIC #). This is a legal requirement for any contractor doing more than $5,000 in work per year in Pennsylvania. You can verify this number on the state's website.
  • Insurance: A reputable contractor will carry liability insurance and workers' compensation insurance. Request proof of both. If they don't have these, you could be held financially responsible for any damage to your property or injuries to their workers while on the job.


Never assume a contractor is insured just because they say so. Always ask for certificates of insurance and call their provider to verify that the policies are active.


Red Flag #5: The Vague or One-Page Contract

A professional contract should be clear, detailed, and comprehensive. It should spell out every aspect of the project, including:


  • Scope of Work: What exactly is being done? (e.g., "Tear off existing siding and install new fiber cement siding.")
  • Materials: Specific brand names, colors, and quantities.
  • Payment Schedule: When and how payments are to be made.
  • Timeline: The estimated start and completion dates.
  • Warranty Information: Details on the warranty for both materials and labor.


If a contractor presents you with a vague, one-page contract or no contract at all, run. This lack of detail leaves you completely exposed to misunderstandings, disputes, and extra charges.
