No Proof of License And Insurance: This is non-negotiable. Ask for documentation and verify it; call the insurance company directly and check the contractor’s licence with your local licensing board or the Pennsylvania Attorney General’s Office. Without proper insurance, you as the homeowner could be held liable if a worker is injured on your property. Without a license, you have little recourse if the work is done wrong.
Full Payments Upfront: A reasonable deposit is standard practice. Full payment or a large majority of it, before any work begins, is not a legitimate payment if schedules are tied to project milestones. A contractor demanding everything upfront is a red flag, regardless of the explanations they offer.
A Supposedly Low Estimate: An estimate dramatically lower than the competition almost never signals a bargain. It usually means cutting corners, unqualified labor, and/or change orders that will inflate the cost once you are too far in to walk away. Get at least three estimates and ask each contractor to explain how they arrived at their numbers.
No Written Contract: A handshake deal is not a contract. Before any work begins, you should have a detailed and signed agreement that covers the scope of the work, materials, payment schedule, timeline, and how change orders will be handled. Without it, you have no legal standing if things go wrong.
They Dismiss Permits: A contractor who suggests skipping permits to save time or money is not doing you a favor. In Pennsylvania, most significant construction requires permits under the PA Uniform Construction Code. As the homeowner, you are ultimately responsible for ensuring your project is properly permitted. Unpermitted work can mean fines, required demolition, insurance complications, and problems at the time of sale.
No References or Portfolio: An established contractor should have no hesitation providing references and examples of past work. When you receive references, call them. Ask whether the work was completed on time, whether the final cost matched the estimate, and how problems were handled. Online reviews are a useful starting point, but real conversations with past clients tell you far more.
High-Pressure Sales Tactics: A contractor who pushes you to sign immediately or offers a steep discount if you agree today is showing you something important about how they operate. A trustworthy contractor is confident in their work and willing to give you time to make a careful decision. Trust your instincts. If something feels off in the early conversations, that feeling is usually worth taking seriously.
