National Home Authority · Homeowner research

Find local contractors. Start with the evidence.

Researching a reputable contractor near you starts with matching the company to your project and location. Compare dated customer feedback, the exact business record, current credentials and a written scope before choosing who to hire.

Browse published NHA profiles below, or use the full directory to search by company and service. You can read the research without submitting a quote request.

Start with a city or metro area

These are starting points from the published directory, not rankings or a complete list of companies in a market. A metro label may include neighboring municipalities. Confirm that the company serves your project address, and open each profile for its research date, complaint context, source links and limits. Display order does not represent quality.

Match the service to the job

A company name or broad trade label does not settle whether it handles your specific project. Use the first conversation to narrow the scope.

  • Plumbing, electrical and HVAC: describe the equipment, symptom and work area; ask whether the proposal covers diagnosis, repair or replacement and who handles applicable permits.
  • Roofing: distinguish a localized leak repair from a full replacement. Compare material, flashing, ventilation, cleanup and warranty scope in writing.
  • Pest and wildlife services: identify inspection, treatment, exclusion and follow-up separately. Ask which work and credentials apply to your situation.
  • Tree and landscape work: list the trees or areas involved, access constraints, debris removal and restoration responsibilities.
  • Garage doors: explain whether the issue concerns the door, opener, controls or structural opening, and confirm the proposed parts and labor.

Compare three kinds of evidence

  1. Business identity: match the legal or trade name, branch, phone and official website. Similar names and nearby offices can belong to different entities.
  2. Public reputation: read recent reviews and the available complaint record together. Look at the substance, responses and reporting period. A star rating or complaint count alone cannot predict your outcome.
  3. Project readiness: independently check applicable licensing or registration with the relevant regulator, request current insurance information and compare detailed written proposals.

For each proposal, record the scope, materials, exclusions, schedule, payment milestones, permit responsibility, cleanup and warranty terms. Ask the same questions so that differences are clear before comparing the price.

Licensing and permit rules vary by trade and jurisdiction. Use the authority responsible for the actual project address; a mailing city or metro label is not enough to establish which rules apply.

What NHA recognition means

New Gold profiles require an exact matched BBB business record showing an A+ letter grade, directly verifiable Google customer ratings strictly above 4.3, identity matching, official-site service evidence and review of available BBB complaint context. BBB accreditation and its letter grade are distinct facts.

NHA Gold does not mean licensing or insurance was independently verified. Review the individual profile’s limitations and independently confirm current credentials. Ratings and business records can change after the stated research date; recognition is not a guarantee of workmanship or future results. Historical or special-recognition profiles explain their own basis.

A clear next step

Choose a relevant profile, follow its original sources and contact the company through its official website. Ask whether it serves your address, handles your scope and can provide the project documents you need. There is no need to decide from a headline or badge alone.
