"Inspection went really well. I was able to follow Scott around as he performed the inspection which was helpful as he explained anything that needed attention as well as pointing out things that were in good or great shape. Any questions were readily answered as well as explanations for anything I did not fully comprehend. I felt the inspection was very thorough and feel comfortable knowing what needs to be done now and in the future. Landmark also arranged for a Pest inspection and Sewer Scope inspection."

"John was a fantastic choice! First off, he was extremely flexible and patient. We had to change the date last minute, and John did it for us even though he was very busy. Then, the day of our inspection, our realtor was an HOUR late... And while we were all annoyed, John was very professional about it and didn't rush to make up for the time. When we first got there, John walked around the outside with his colleague and showed us all of the little things he noticed. This is my husband and I's first home, so we don't know what to look for usually. John also showed us a HUGE issue with the roof/addition to the house and explained it to us in a way that was easy to understand. Once our realtor finally arrived and we got inside, they did an extremely thorough job of inspecting everything. They showed my husband all the issues with the roofing and other parts of the home. All in all, I learned a lot about the home we are hoping to purchase (once it's fixed). John did a phenomenal job explaining everything to us. His report came with many pictures and great explanations. If for some reason this deal falls through, he will be the guy we call to inspect the next house."

FAQs for radon gas abatement projects in New Castle, 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.
