"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.

"My house had excessive levels of radon in our lower level. The Lance Dorfi team installed a pump to pump out the radon and release it up above the roof of the house. Since then, radon levels in that part of the house have been very low, so the problem was resolved. The work was done on budget, and they did an excellent job with scheduling and customer service. I recommend them for dealing with radon."

Veteran owned indoor air quality testing, engineering and consulting firm. Some risks are unavoidable but Indoor Air Pollution is a risk you can do something about. IndoorDoctor engineers test for possible environmental hazards, such as poor air quality. We define your environmental concern, evaluate its significance, and develop corrective actions or preventative plans to reduce the perceived hazard. Our reports are totally unbiased as we are not in the remediation business. For example, we have helped our clients to identify air quality issues that are contributory to ill-health such as molds and allergens. Many of our customers request air quality assessment before investing hundreds of thousands of dollars in a real estate purchase. Other customers use our reports to support insurance claims. But all of our customers want the peace of mind that knowing the air they are breathing is free of environmental contaminates.

"I explained to Jeff that I had bought a new condo, which was new construction, and I had concerns that the HVAC was not properly working and I wasn't getting enough clean air. Jeff was able to come the very next day. He is incredibly knowledgeable and clearly passionate about what he does. He conducted many tests - toxic gas levels, dust, mold, dander, etc. After about 30 minutes of testing, he identified I had a slow gas leak in my gas fireplace, which apparently had not been installed right. He stayed with me while the gas company came to remedy the situation. I am so grateful for him or I would never have known about the leak, which was probably contributing to health issues I was having. He also was able to turn around the other lab results incredibly quickly. Several others in my building have since hired him. Can't recommend him enough."

We offer a full range of inspection services, including residential home, condo/townhouse, and commercial building inspections. Services include testing for Radon levels, Water quality and Well functions along with Pest and Mold detection. With over 25 years of Renovation experience, we pass along our extensive home knowledge to each customer, and offer guidance and solutions specific to each home when needed.

"The inspection was a farce. We received a list of very minor repairs that needed to be done along with a couple of recommendations for system replacement due to age in the future. The inspector did not go up on the roof. If he had, he would have seen how soft the roof was. My wife notice the porch roof leaking during our remodeling project as the insulation was wet. Our contractor walked the entire roof and said it was an emergency to replace it. Sure enough 1500 sq feet of plywood of a 2000 sq foot roof had to be replaced. It was soft, splintering and wet. The splintering and disintegration should have also been visible from the attic hatchway. I am out $12,500 because of his negligence or laziness, I am not sure which. Do NOT use this company under any circumstances."

Radon Detection and Reduction questions, answered by experts

Yes, DIY kits are available, but professional testing provides more accurate results and comprehensive reports.

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

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.

Costs depend on property size, test types, and additional services like mold sampling.

Use a radon test kit or hire professionals to conduct a detailed assessment of radon levels in your home.
