Tipper's guide to hiring a radon contractor in Texas

Not every company on this list has been personally vetted by Tipper. This is a directory built from publicly available data. Here's how to do your own due diligence before hiring anyone.

Check their certification

Ask specifically whether the contractor is certified by the NRPP (National Radon Proficiency Program) or NRSB (National Radon Safety Board). These are the two EPA-recognized programs. A legitimate pro will have a certification number they can give you.

Get at least two quotes

Mitigation system costs vary. A typical sub-slab depressurization system runs $800–$2,000 depending on home size, foundation type, and labor rates in your area. If a quote is dramatically lower, ask what's included.

Ask for a post-install test

Any reputable contractor will do a follow-up radon test after installing a mitigation system to confirm it's working. If they don't offer one, ask for it explicitly. You should see levels drop to below 2 pCi/L in most cases.

Reviews matter, but read them

Star ratings are a useful filter, but read a few actual reviews. Look for mentions of professionalism, whether they explained what they were doing, and whether the follow-up test came back clean. Those details tell you more than the number.
