"Jose Rodriguez was prompt, professional, and fast with results. He was there when he said he would, went there the next day after I called, and provided the results on time. As a real estate professional I know I'll need the services again and I know that he is the person I will be calling. Thank you!"

"Chuck was recommended to me by my realtor. He showed up late, but said that was due to an accident and resulting traffic. That is not surprising on a Friday afternoon. He thoroughly inspected my house, was very patient about answering questions and was not shy about telling me his honest opinion about the house's strengths and weaknesses. The report he submitted was neatly prepared and easy to read and included several digital photos. He identified several electrical issues that we would never have known about otherwise and encouraged us to get additional professional advice. We did and the sellers are fixing for us. When I had a follow up question for him, he responded promptly via email. He also encouraged me to contact him if we saw any issues at final walkthrough."

"Very easy to get an appointment on short notice when I had limited time to get a radon test done in the process of purchasing a home. Their price was also slightly lower than an estimate I'd received from another company, and the technician was more thorough about explaining the process than the other company I considered."

"The estimator examined the basement walls and identified four cracks through which water might be coming in and gave a quote.  We agreed to have the work done.  One service man came and filled the cracks in less than the estimated time.  The work involved surface patching the cracks on the inside of the wall, drilling approximately six holes through each crack and injecting a sealant into each crack.  Since we haven't had a hard rain since then, we haven't had a real test of whether it holds water out.

"Chuck asked all the right questions before giving a quote and gave us multiple options to address the problem leaks. His serviceman, Josh, was courteous and professional, clean and efficient. They filled two basement cracks with the injection sealant and we are pleased with the results. I would use them again.

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).

Ideally, no one will live in a house with elevated radon levels, as prolonged exposure increases the risk of serious health issues like lung cancer. However, homes with radon can be made safe through mitigation systems, such as active soil depressurization. Testing for radon regularly and addressing high levels helps ensure a safe living environment.

No, air purifiers are not an effective way to reduce or remove radon. Radon is a radioactive, inert gas that cannot be filtered by standard air purifiers, which are designed to capture particulates like dust and mold. While an air purifier can improve indoor air quality by removing other pollutants, it should not be relied upon for radon. The only effective solution for high radon levels is a dedicated radon mitigation system.

You can vent radon out of your house sometimes by simply opening a window, but it won’t remove the source, and will likely rise above recommended levels quickly. A professional will be needed to assess your home, and determine the best strategy for radon removal. Active radon sump pumps and soil depressurization systems are often used to forcefully vent the radon from your home.

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.
