What should I do this week if two quotes differ?

Confirm your radon test result first, since mitigation is generally recommended at 4 pCi/L or higher. Ask each company to put the proposed system type in writing and explain why it fits your foundation. Compare the quotes on that written plan, not just the price.

Why might one company propose a different method?

Sub-slab depressurization is the standard fix for slab and basement homes. Another method may be proposed if the home has a crawlspace, sump pump, or a foundation layout that calls for a different design. The quote can differ because the building and mitigation design differ.

How do I know who is legitimate?

A real pro should be certified, not just a general handyman. Certified mitigation specialists hold certification from the National Radon Safety Board (NRSB) or AARST-NRPP. Ask for proof of certification and check that the quote includes post-mitigation verification testing.

What should a quote include?

The quote should name the system type and explain the design in writing. It should include post-mitigation verification testing, since testing and mitigation work together. Ask the pro for proof of license and insurance before you sign.

Quick answers

Is sealing cracks enough to lower radon levels?

Sealing gaps and cracks helps reduce radon entry, but it is generally paired with a mitigation system. Quotes often include both because radon seeps in through gaps around service pipes and foundations.

How do I verify a contractor's NRPP certification?

Check the NRPP certified-professionals listing and confirm experience, references, licenses, and skills for the work. Ask the pro for proof of certification before hiring.
