Discovering elevated radon levels in your home is concerning, but finding the right solution shouldn't add to your stress. Because radon is the number one cause of lung cancer among nonsmokers, addressing it requires precision and expertise. Choosing a qualified professional such as RDS Environmental ensures your family is protected through effective radon mitigation. This guide outlines exactly what criteria you need to evaluate, from specific certifications to post-installation radon testing, ensuring you hire a team capable of delivering lasting results and safer indoor air.
What Certifications Should a Radon Mitigation Contractor Have?
When evaluating a professional for radon mitigation, credentials are the most reliable indicator of competence. Radon reduction is a specialized trade involving building science, physics, and airflow dynamics, not general handyman work. Consequently, you should look for technicians with specific qualifications:
- NRPP Certification: Indicates the technician has passed rigorous exams and adheres to strict standard operating procedures.
- IEA Membership: Shows a commitment to the International Association of Radon Scientists and Technologists and keeping up with EPA standards.
Beyond paper credentials, practical experience is vital. The best contractors often possess a background in home inspection or general construction. This knowledge allows the crew to identify how structures—like slab foundations or crawlspaces—contribute to radon entry. A certified specialist with deep structural knowledge can design a custom solution rather than applying a "one-size-fits-all" approach. Always ask about their specific experience with homes similar to yours to ensure they have the specialized knowledge required to tackle the project.
Should a Radon Mitigation Company Be Licensed and Insured?
Hiring a licensed and insured company is non-negotiable for structural modifications. Radon removal involves drilling concrete, running piping, and electrical work. If an uninsured contractor causes an accident or injury on your property, you could be held liable for the costs. A reputable company carries General Liability Insurance and Workers' Compensation, protecting your finances and proving legitimacy.
While uninsured contractors may offer lower estimates, the risk to your home outweighs the savings. Furthermore, professional companies comply with local regulations. In Colorado, for instance, specific statutes govern the industry to protect consumers. A licensed company is accountable to state boards, providing extra protection. Always ask for proof of insurance during your estimate; a professional team will happily provide it to demonstrate they take their business seriously and stand behind their workmanship.
How Do You Know if Radon Mitigation Worked?
Post-mitigation testing is the only way to verify that a system is functioning correctly. Since you cannot see or smell radon, visual inspection isn't enough. A follow-up test is required to ensure levels have dropped below the EPA action level of 4.0 pCi/L. Results aren't always instantaneous; while the fan creates a vacuum immediately, it can take up to a week for airflow to stabilize.
A reputable company will schedule a re-test accordingly. Beware of claims that levels will drop to "zero." The goal is safer levels. If post-mitigation results remain high, the provider should have a plan to adjust the system, such as sealing additional cracks or upgrading the fan. Always check their guarantee regarding effectiveness to ensure your family's health risks are truly reduced.
How Often Should a Radon Mitigation System Be Inspected or Serviced?
While durable, radon systems are mechanical and require periodic monitoring. Homeowners should frequently check the manometer, a U-shaped gauge on the vent pipe. If the liquid is uneven, the system is active; if level, the fan isn't generating suction and requires repair. Beyond self-checks, professional inspection is recommended every few years or if the fan makes unusual noises. Most fans last five to ten years depending on workload.
Additionally, ground settling or renovations can alter radon entry points, potentially bypassing the system. A professional service check ensures suction points aren't blocked and the system remains effective. Hiring a company that offers repair services is very beneficial, ensuring you have a partner to maintain the system for the long haul rather than just performing a one-time installation.
