"The overall customer experience was awesome. From my initial conversation with Scott, he thoroughly explained the inspection process. I knew what to expect with the inspection and he delivered. One of the many things I truly appreciated is that the inspection was all inclusive. A representative came to do the Terminate inspection and another representative completed the water testing. I viewed this as one stop shopping and very helpful to me as there is so much to do when purchasing a property. Scott and his team were on time and very professional. While at the inspection, I walked through the property with Scott as he thoughtfully explained everything. He explained things in a way that I understood; I would say that Scott provided great teachable moments. I left the inspection having a keen understanding of the issues identified at the property and felt valued as a customer. I would highly recommend Scott and his team. The quality service was worth every penny. Thanks so much Scott!!"

"Because we anticipate moving to a CCRC soon, we wanted to get our house "in shape" so it could be easily sold; no glitches, like radon above 4.0 pCi/L, which we've known it was for many years. Recent long-term tests of cancer rates among people in homes with radon above 4.0 vs. those below 4.0 produced some surprising results: People in homes with LOWER than 4.0 had HIGHER incidents of lung cancer than those with radon ABOVE 4.0. But, of course, the EPA is intractable on the subject, so ignores such studies, forcing homeowners with >4.0 pCi/L to spend a fair amount of money to reduce it below the arbitrary 4.0 before they sell their house. We contacted two companies. The first offered by far the lowest price, but did so without anyone from the company coming to the house to see what would be involved. We have a poured-concrete basement with a French drain all the way around it. A French drain is great if you have water seeping through the walls because it allows the water to drain back into the ground. But it also provides a path for radon to enter the house, so it has to be closed. In addition, you would not want to leave the drain open because the remediation is done by an exhaust fan that pulls the radon from under the basement floor and discharges it above the roof. Leaving a French drain open could cause the exhaust fan to create a negative pressure in the house, thereby pulling cold air in the winter and hot air in the summer into the house. So it had to be closed. I asked the first company if their quote included sealing the French drain. Their response was that they could seal all cracks in the floor, but the responder didn't know about the drain. Two emails to them about that question were ignored. The second company was Reliable. Although their bid was higher, the company owner came to the house (on time!), inspected the basement thoroughly and explained in detail what they would do, which included sealing the French drain. They used our sump (we have no sump pump) as the radon extraction point. If you don't have a sump, they have to cut a hole in the floor. In order to seal the French drain, they give you the option of (a) moving everything away from the walls or (b) adding $100 to the estimate and they will move the stuff for you. We moved it ourselves. The job was finished in 4 hours and was beautifully done. The only "con": The cover that seals the sump was left with lots of PVC glue spilled on it and on the floor around it. Not a big deal, but it will require us to clean it up with solvents and paint the cover so it looks neat. We highly recommend this company. In our opinion, they're a perfect example of "you get what you pay for"."

"The work was done quickly and we retested but the gas rating was still high. I got a recommendation from Matt to caulk some additional cracks and Matt came back and drilled pilot holes to confirm the draw of the system across the full basement and everything there was good. Then we retested successfully. Bottom line Matt and Heather were very responsive to my needs, their service and support were excellent and of all the contractors I've had in my home they were by far the very best! <br />"

"<p>it was superb! they easiest, hassle free Radon test in town, with extremely proficient people -- very knowledgeable and very people-friendly! they took their time to explain things on the phone to me before I committed. the test came back within 10 days or so -- via email. which is very convenient. it was very clear as it is, but I like talking through it and get advice. they were instantly available to discuss. they gave me future tips to keep on top of all things Radon related. </p> <p>I have to say that all this comes to be after 3 months of many back and forths with 3 other companies -- none of the other companies could be bothered to schedule a time, and those who did, never showed up.. many times over. I don't know why I was so patient with them and I wish had discovered Environmental Testing & Research Laboratories much sooner.</p> <p>Really highly recommend them!</p> <br />"

"Hi. I'm Steve Cmielewski. Buying or selling a house is a big deal. I want to make sure that your property is free of any major real estate problems or defects..."\n\nI invite you to come out with me on the inspection so I can 'introduce' you to the home you potentially may be purchasing. This also gives you the opportunity to ask questions as we come across any issues together.

FAQs for radon gas abatement projects in Dover, DE

The only way to know whether your home or water supply contains radon is to schedule a professional test. A qualified radon inspector will collect samples, deliver lab-verified results, and explain the findings for $150 to $800. Once you know your exact levels, you and your radon mitigation pro can choose the right system and tackle the problem before it affects your family’s health.

Both roles tackle radon, but they focus on different steps. Inspectors test your home, interpret the results, and determine whether levels exceed EPA guidelines. Mitigation pros design and install the system that lowers those levels. Some companies do both, but the skills and equipment differ, so always verify that the person you hire is properly certified for the specific service you need.

Installing a mitigation unit fixes radon problems by reducing indoor gas levels to established safe standards. A system designed and installed by a mitigation expert, tailored to your home's specific layout and foundation, guarantees effective radon reduction. This expert installation ensures consistent performance over time while safeguarding your indoor air quality.

Open windows and doors do not reduce radon levels because they trigger a pressure imbalance that draws radon-laden air into your home. This practice fails to control radon concentration and can even worsen the issue. An active suction mitigation system provides a proven, safe, and effective solution to reliably reduce radon levels.

Radon mitigation systems generally last between 10 and 30 years, depending on system type and maintenance. Passive systems endure the longest because they have no moving parts, whereas active systems, which use a fan, require fan replacement every 5 to 10 years. System components, such as PVC pipes, seals, and fittings, can remain effective for decades when paired with periodic inspections and proper maintenance.

Radon mitigation systems consume between 300 and 3,000 kWh of electricity per year, depending on fan size and system design. On average, an active radon fan draws 100 to 300 watts continuously, which translates to roughly 876 kWh annually, and adds $30 to $300 to your energy bill each year. Choosing a high-efficiency fan and ensuring tight sealing around pipes helps minimize these ongoing costs.
