"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

Radon is present almost everywhere but, like sunlight, the concentration levels and how often you are exposed to it have a large part to play in just how dangerous it is. There are levels of radon that are acceptable inside a house, but above a certain limit, radon becomes a serious radioactive hazard that is a known cause of lung cancer. In fact, radon exposure is the number two leading cause of lung cancer (after smoking).

Professional radon detection involves placing test kits in the lowest lived-in level of the house for a period, usually 48 hours to several months, followed by lab analysis of collected data.

Sampling typically takes 1-3 hours, and depending on the provider, lab results are available within 2-7 days.

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.

Short-term tests take 2-7 days, while long-term monitoring may require up to 90 days for accurate results.
