How We Rank Contractors in Fort Collins
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.

What should I look for when choosing a radon contractor?
Focus on strong ratings with meaningful review volume, current professional certifications (NRPP or NRSB), and clear service coverage for your home type. A good contractor will assess your specific foundation and provide a written scope that includes suction point count, pipe routing, fan specification, and post-mitigation testing.
How are these Fort Collins contractors ranked?
We rank contractors using a transparent, data-only methodology: Google rating first, review count second, and certification count third. Sponsored placements appear in a separate, clearly labeled section and do not influence organic ranking position. All ranking data comes from verified sources including Google Business profiles and national certification databases.
Should I get multiple quotes in Fort Collins?
Yes. With 16 contractors in Fort Collins, getting at least two written quotes is practical and recommended. Compare the number of suction points, fan model, pipe routing plan, warranty length, and whether post-mitigation testing is included. Price alone is not a reliable differentiator — system design matters more for long-term radon reduction.
