"Professional, friendly and responsive. I hired Alpha to come do a mold inspection on a home I just purchased. They accommodated my schedule and Chris came early morning before work to do the inspection. He was very friendly, thorough, and went above and beyond to make sure he tested everything I was looking for. He eased my mind and he even gave me home advice outside of just the mold inspection. The inspection price was incredibly reasonable and the bid to do some work was as well. He could have tried to oversell me on things due to my lack of knowledge about mold but in the end my house was in good shape and he eased my worries and gave me peace of mind which was well worth the price! I would highly recommend Alpha Environmental!"

"You need to ask the technicians what to do and when regarding the re-test. The information we received was insufficient to know what to do afterwards and our re-test was delayed X 4 days because of lack of communication. Otherwise VERY Happy with the actual work and costs for the work."

Radon Detection and Reduction questions, answered by experts

The cost for a radon mitigation system typically ranges from $800 to $1,500, with an average around $1,000. The final price depends on several factors, including the size of your home, the severity of the radon issue, and the type of system required. Your home's foundation type also significantly impacts the cost. For example, sealing and ventilating an unfinished basement might cost around $4,600, while encapsulating a crawl space without a foundation slab can range from $1,500 to $15,000.

Your radon fan needs to operate 24/7 to be effective. The only time the fan isn't operating is during its replacement. Radon levels in the home can increase within hours if the fan stops working or something obstructs the stack vent. Fortunately, radon systems require no downtime maintenance between fan changes.

The natural breakdown of uranium in soil, rock, and water can cause radon to appear in a home. The gas seeps into homes through cracks in foundations, walls, or floors, as well as through gaps around pipes or construction joints. Radon levels are influenced by soil composition, building materials, and ventilation. Poorly sealed or airtight homes can trap radon, allowing it to accumulate.

If high radon levels are detected, steps include sealing entry points, installing a mitigation system, and retesting the air regularly to ensure reduced levels.

No level of radon is technically safe, but since it is naturally present everywhere, it is impossible to avoid entirely. The average radon level in homes across the United States is 1.3 picocuries per liter (pCi/L). The Environmental Protection Agency (EPA) recommends taking action to reduce radon levels if your home's test results are between 2 and 4 pCi/L or higher.
