What is the cost of a radon mitigation system?

<div><p>If radon is present in your home, you can expect to pay around <b>$1,000</b> for a <a href="https://www.angi.com/articles/how-much-does-it-cost-remove-radon-gas.htm">radon mitigation system</a> or between <b>$780 and $1,250</b> in most cases. The exact price will depend on the severity of the radon leak, home size, and the protocol the radon specialist develops to remove radon from your home and keep it out. Your foundation type will also affect your radon mitigation system cost, as unfinished basements will cost about <b>$4,600</b> to seal and ventilate, while crawl spaces without a foundation slab may need extra encapsulation, costing <b>$1,500 to $15,000</b>.</p></div>

Can I do radon testing myself?

<div><p>You can buy DIY radon test kits from a home improvement store and conduct radon testing, but these tests are often inaccurate. No matter the result, you should supplement DIY testing with professional radon detection and analysis. DIYers only have access to passive radon tests, which aren’t as reliable as active tests that professionals use. Plus, it’s very easy for DIYers to make mistakes during testing, leading to inaccurate results. If you’re moving into a new home, have concerns about radon, or are due for an updated test, hire a professional. </p></div>

How much does radon testing cost?

<div><p>Radon testing costs depend on whether you hire a professional radon inspector or DIY test. You can expect to pay <b>$150 to $800</b> to hire a local radon inspector, and home-testing kits range in price from <b>$15 to $250</b> from home improvement stores. However, it’s best to trust a professional inspector with this task to ensure accurate results. Plus, if you have radon in your home, your testing company can develop a mitigation protocol to keep you and your family safe from the dangerous gas, so it’s well worth the money to hire a professional.</p></div>

Is radon testing really necessary?

<div><p>Yes, radon testing is absolutely necessary if you suspect the presence of this hazardous gas, and the Environmental Protection Agency (EPA) recommends testing for all homes in the country. Radon is a pervasive natural gas that can leak through your home’s foundation and seep into the living areas. Unfortunately, the gas is highly carcinogenic and is the second leading cause of lung cancer. Radon testing is crucial for keeping you and your family safe from harm, so hire a radon mitigation specialist to test your home if you suspect its presence in your home.</p></div>

Does a radon testing company need to be licensed or certified?

<div><p>In most states, radon testing companies don’t need to be licensed or certified by the state, but the companies that analyze the test results and develop radon mitigation protocols do. You should choose a radon testing company that suits your needs, but before hiring a mitigation specialist, check our <a href="https://www.angi.com/angi-license-check.htm">state licensing tool</a> to make sure the company is properly certified.</p></div>

25 EMPLOYEES NO SUBS.

"Excellent company. Iwas freaked out and they calmed me down (call them before you lose sleep!) It's not as bad as it seems. Showed up right on time. Gave an excellent consult that didn't feel rushed nor about just making money (instead.. doing it right!). The actual remediation (all the dry wall in the bathroom, cutting new electrical holes, etc was done to perfection with a clean air test and no debris. They respected HOA rules and they got all this scheduled after permits. It was a seamless stress-free process and ironically it was also the most affordable."

At BPG, we believe home inspections shouldn't end at the driveway. Our inspectors and engineers undergo thorough background checks and must meet ongoing training and performance standards -- they are a selective group of professionals.With so many inspection companies to choose from, how do you select one that fits your needs? We've earned a solid reputation for standing behind our work and providing distinct value advantages that help protect our clients.

"BPG Inspections Failed to Honor Their Guarantee or Take Accountability Summary: In my experience, BPG Inspections failed to uphold their guarantee, and I encountered poor follow-up and vague, shifting justifications for denying my claim. Details: I hired BPG Inspections in Pensacola, FL, to inspect a home I purchased in April. The inspection occurred in March, and I moved in during May. Within a few days of moving in – well within the 90-day warranty period – I discovered two issues that the inspection report had explicitly marked as functional: 1. The garbage disposal unit did not work (it made a soft noise but did not function). 2. The HVAC system failed to deliver air to the kitchen and adjacent bedroom, though the inspection report had indicated the air handling was operational and in good condition. I promptly emailed BPG about these problems, and while the inspector initially responded, I was then passed to their claims department. After repeated follow-ups, I finally received a call on June 23rd – nearly a month after reporting the issue – only to be told that neither issue was covered under their warranty. I raised the following concerns: 1. For the HVAC, the inspector had confirmed it was functional in an email, contradicting the claims department's later justification that it could not be tested. If no air reaches two rooms, it should have been evident during either heating or cooling tests – this was missed. 2. For the garbage disposal, I was told it was a "kitchen appliance" and therefore not covered, despite it being a fixture included in inspections. When I asked where the warranty excluded it, I received inconsistent explanations. At no point did the company offer to re-inspect or further investigate these issues. I expected more accountability from a professional inspection service – especially one offering a guarantee."
