"I actually hired Frank by accident, but he got the business because he was responsive, professional, and informative. I am so glad I made this mistake! He was very thorough and gave me very detailed information during the inspection and in the inspection report. I couldn't be happier with this process and will be calling him again in the future.

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

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.

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.

DIY radon detection is possible using over-the-counter test kits, but professional testing can provide more accurate assessments, especially in cases of high initial readings.

Yes, most services include testing the generator to ensure functionality. Confirm with your provider.

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.
