"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!"

Radon Detection and Reduction FAQs, answered by experts

You'll need to test your home for radon after installing the mitigation system, then again every two years. If radon remains elevated, contact a licensed radon professional, either the contractor who installed the system or a different one, and have them evaluate the system. They may need to make some changes to improve its effectiveness and performance.

Long-term exposure increases lung cancer risks. Prolonged homestay individuals and smokers encounter heightened vulnerability and exposure concerns.

Radon is the number one non-smoking cause of lung cancer in the United States, but it can cause some other concerning side effects in the meantime. If you have a raspy voice, chest pains, trouble breathing, difficulty swallowing, or any of the above, don’t hesitate to perform radon testing and install a mitigation system as soon as possible.

Your radon mitigation system may be loud because it’s time to replace it. Any sounds are usually from the inline fan that helps create the vacuum and resulting airflow. If you hear a new, loud mechanical or humming noise from your radon fan, it might be time to replace it. Most fans used in radon mitigation systems last up to 10 years, but may need to be replaced sooner.

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.
