"Overall the job went well. From diagrams I received before the job, I expected the pump to be installed in my partial basement since it is lower than the crawl space. Instead it was installed in the crawl space, drawing air from beneath the plastic they installed. I had had an electrician working on the house, and he had run new wiring for the living room but had not yet connected it. The installers chose to use this wire to power the pump. I learned this when the electrician came back and told me they had taken his wire. This was disappointing. The installers left a follow-up test kit and gave verbal instructions to install it two weeks after the installation in a closet for seven days. However, the printed instructions said NOT to install in a closed space such as a closet, but to put it in a central location. Close to the thermostat was said to be best. The instructions also said that the test must be between 3 and 7 days, with 4 days being the optimal. Again, the company seems to be ok, the pricing was $1000 less than one quote and $400 less than another, but the installers' knowledge and experience may vary."

Radon Detection and Reduction questions, answered by experts

There are steps you can take as a homeowner to remediate radon yourself. While a radon reduction professional can make the biggest impact in your home, you can make efforts to improve radon levels on your own by sealing cracks, increasing ventilation, and testing for radon regularly.

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.

It is possible to test for radon yourself using DIY radon test kits, but these at-home test kits should never be a replacement for professional radon testing. DIY test kits can provide some information about radon exposure in your house, but your indoor temperature and humidity can affect the results, as can improper usage of the test kit. You could save yourself some money by hiring a radon professional to begin with, and when it comes to your family’s safety, hiring an experienced professional to do the testing is usually the best option.

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.
