How to Spot a Bad Contractor: 7 Red Flags Every Homeowner Should Know

Hiring a contractor is one of the biggest financial decisions a homeowner makes. Get it wrong, and you could lose money, deal with shoddy work, or end up in a legal battle. Here are 7 red flags that should make you walk away — fast. 1. They demand large upfront payment A legitimate contractor never asks for more than 10-25% upfront. If someone wants 50% or more before lifting a finger, that's a major warning sign. Most states actually limit how much a contractor can collect before work starts. In Washington, for example, it's 25% or $1,000 — whichever is less. 2. No written contract "We don't need paperwork, just a handshake." Run. A real contractor will provide a detailed written contract covering scope of work, materials, timeline, payment schedule, and warranty. No contract means no protection if something goes wrong. 3. They can't show a license or insurance Always verify the contractor's license number with your state's contractor board. Ask for proof of liability insurance and workers' compensation. If they hesitate or can't produce it, walk away. An unlicensed contractor leaves you liable if someone gets hurt on your property. 4. The bid is dramatically lower than others Got three quotes? If one is 30-40% lower than the others, that's not a deal — it's a trap. Cheap bids almost always mean cut corners, low-quality materials, or a contractor planning to hit you with "unexpected" charges later. 5. They pressure you to decide today "This price is only good if you sign today." High-pressure tactics are a classic scam. A reputable contractor will give you time to think, compare, and ask questions. 6. No physical address or local references A contractor with no office, no website, and no verifiable past work is a huge risk. Ask for at least 3 recent references in your area and actually call them. Drive by completed projects if possible. 7. Cash-only payments Demanding cash means they want to avoid taxes and a paper trail. If something goes wrong, you have zero proof of payment. Always pay by check or credit card so there's a record. How to protect yourself The easiest way to avoid contractor nightmares is to use a verified directory like WorkTime Alliance.
