How We Rank Contractors in Chicago
Our ranking methodology is transparent and data-driven. Sponsored placements are clearly labeled and appear separately — they do not influence organic ranking position.
- Google rating — Higher average ratings rank higher. This reflects real customer satisfaction across verified Google Business profiles.
- Review volume — More reviews break ties between similar ratings. A 4.8 with 50 reviews outranks a 4.8 with 3 reviews because the signal is more reliable.
- Certification count — NRPP and NRSB certifications break remaining ties. More certifications indicate broader competency across mitigation, measurement, and specialized techniques.
- Data integrity — All ranking data comes from verified sources: Google Business API, NRPP/NRSB certification databases, and contractor websites. Template-generated or unverifiable data is excluded.
