How to choose a contractor

A practical checklist for finding, vetting, and hiring a professional: what to verify, what to ask, what belongs in a contract, and which warning signs to take seriously.

Information only. This guide is general education, not professional, legal, or financial advice, and it does not contain quotes or estimates. Rules, prices, and best practices vary by location, so confirm details with your local building department and qualified professionals.

Know what kind of help you need

Not every project needs a general contractor. A single-trade job such as replacing a water heater or repairing a roof may go to a specialist directly. A project that involves several trades, such as a kitchen remodel, often benefits from a contractor who coordinates the work, orders materials, and schedules inspections. Designers and architects help when layout or structure changes. Decide who will coordinate before you start collecting bids.

Find candidates the careful way

  • Ask friends, neighbors, and coworkers who recently completed similar work, and ask what they would do differently.
  • Check with local building supply stores and your city or county for lists of working professionals.
  • Look at recent, similar projects and, where possible, speak with former customers.
  • Be wary of anyone who knocks on your door offering a deal that expires today, especially after storms.

Trowelo does not recommend, rank, or refer contractors. The goal is to equip you to evaluate anyone you find.

Verify before you trust

Credentials are easy to check and easy to skip. Do it every time.

  • License: many states license contractors or specific trades. Look up the license number on the official state or local licensing website and confirm that it is active and matches the business name.
  • Insurance: ask for a certificate of insurance showing general liability and, where required, workers’ compensation coverage. Ask your own insurer or the contractor’s agent to confirm if you are unsure.
  • Complaints and reviews: check your state consumer protection office, a local consumer organization, and independent review sites, and read negative reviews for patterns.
  • Business details: a real street address, a working phone number, and a business name that matches the contract.

Ask the right questions

  1. Who will be on site every day, and who is my main contact?
  2. Which parts of the job do you do yourselves and which do subcontractors do?
  3. Who pulls the permits and schedules inspections?
  4. What is the realistic start date and the expected duration, and what could change them?
  5. How are changes and surprises handled, priced, and approved?
  6. What warranty do you offer on labor and materials, and in writing?
  7. Can you share references for projects similar to mine?

Put everything in writing

A written contract is not a sign of distrust. It is how both sides stay on the same page. A good contract usually includes the full scope of work, product names and models, the total price and payment schedule, start and completion dates, how changes are handled, the warranty, a cleanup commitment, and the contractor’s license number and insurance details.

Watch out

Do not pay the full amount up front, and be cautious of large cash deposits. Tie payments to completed milestones, and keep copies of every document, receipt, and message.

Red flags worth walking away from

  • Pressure to sign immediately, or a price that is “only good today”.
  • No written estimate, or a vague one with few details.
  • Requests for large cash payments or most of the money before work begins.
  • Reluctance to show a license, insurance, or references.
  • Suggesting you skip a permit that your city requires.
  • An estimate that is dramatically lower than all the others without explanation.

During and after the work

Stay involved without hovering. Agree on a regular check-in, keep a shared record of decisions, and do a walkthrough before final payment with a written punch list of anything unfinished. Hold back the last payment until the list is complete, permits are closed, and you have final lien waivers, warranty paperwork, and manuals.
