"I highly recommend Apex Radon Solutions. From getting the estimate to getting the work done, everything was just outstanding. Marco and his crew of 3 men showed up early and were all knowledgeable and extremely skilled. I had to install a radon fan and put in piping and electrical. They measured the piping with care and accuracy and did an excellent job with the installation. Iâ m truly impressed with the professionalism and quality of the work.

"Lesson learned. Always get an estimate. BEFORE the work is done. At least a digital copy. Arrangements for the project were made, with some one named Lynn, for the company to send someone to complete the work. We were quoted over the phone 4500-5000 which included a mold test. A sub contractor with an entirely different company (National Mold Company) was sent. When the contractor arrived, he stated that the job would be much more simpler than first thought. This led us to believe that the job would cost less, no. All said and done, they charged $5500. All said and done, it's almost like no work was done. The stains and the smell are still there. Only one actual board was taken upon the attic room. The ceiling in the bedroom was primed and painted but are still visible and have a funky smell. At this point I'm going to. Do what we should have done; Do the job ourselves. Just now with $5500 less dollars in our pockets. A detailed receipt was not given even though it was requested."

Radon Detection and Reduction questions, answered by experts

Properties should ideally be tested for radon every 2 to 5 years or sooner when changes to the property structure or ventilation occur that might impact airflow.

If your home has a sump pit, you can integrate it with a radon mitigation system. You can accomplish this by sealing the pump cover with an airtight lid that accommodates radon vent pipes and sump pump hoses. This allows the vent pipe to redirect the radon gas outside of your home.

Keeping radon from getting into your home is much better than having to get rid of it once it's already indoors. While there may not be a way to fully prevent radon from getting into your home, there are things you can do to reduce the gas's ability to enter. 

Sealing foundation cracks and openings can help keep the gas from seeping inside. Improving air flow, such as by opening windows, can also be helpful. If you're building your home from scratch, talk to your contractor about using radon-resistant construction to keep the gas out.

To determine whether you have radon in your home, you must run a test. Radon gas has no odor or color, so you won’t notice a concentration of radon. You could purchase a DIY test at a local hardware store, but it may not deliver completely trustworthy results. The best way to test and receive accurate results is to hire a local radon detection specialist.

Radon testing costs around $450 on average, but you could pay between $150 and $800 for testing, depending on a few factors. The size of your house is one of the most significant cost factors, as your radon professional will have to set up additional tests for homes with larger footprints. The type of test can also have an impact on the cost. Finally, some radon testing companies will include a recommended protocol for radon mitigation, while others might charge $50 to $100 extra.
