Customers say: Quick response

"After my basement test come back with significantly elevated radon, I contacted radon abatement services at the recommendation of a neighbor. A day and a half later, they were on site. While performing the initial walk through, the experienced and thoughtful professionals adapted their plan to utilize my sump pump. This was an effective strategy as it addressed the main source of radon and concealed the system in completely unfinished space. I just received my post mitigation radon results, and the system is working phenomenally. To sum it up, I was blown away by the responsiveness, thoughtfulness, and reasonableness and can't say enough positive things about this company. I don't ever post reviews, but in this circumstance I absolutely had to."

"Mike and team were very knowledgeable and patiently answered all of my questions (and I always have a lot of them when dealing with contractors). They know their stuff and didn’t oversell or make false promises. I already had a mitigation system in place over my sump pit that came with the house, but it wasn’t adequate to service the multiple slabs that make up my foundation. Mike suggested a stepped approach to deal with the “hot spots” in the house and then re-assess whether additional action was necessary. They installed a clear lid over my sump and fixed the trap in my pit so that the existing fan was actually pulling suction on the foundation (and not the open drain from my exterior stairs). They also installed a second system that serviced two slabs and vented out through the back of the roof. Finally, they sealed up some cracks and holes around the foundations. Mike found a solution that was sensible from an aesthetics perspective as well as functional. The pipe runs through my entryway closet, and is as hidden and cleanly installed as I could have hoped for. We had a difference in opinion on how the finished roof flashing should have been done (more from an aesthetics perspective), but it’s on the back of the house behind the chimney so I wasn’t overly concerned about it. The system has reduced my levels to around 1pc/l down from a previous average of about 8 pc/l. So definitely within acceptable levels. I’m only a month in, so will continue to monitor over the next year to determine if any seasonal impacts require further action. I would definitely recommend them and plan to use them again if I need to (although I hope I don’t have to). If you are looking at this and don’t have your own continuous radon monitor, I recommend picking one up."

"It went very well. I HIGHLY recommend Home Detective. You can tell from the first phone contact with Robert that he knows what is doing. <br /> He was very professional on the phone and during the inspection. <br /> <br /> Robert thoroughly inspected every corner of the house and found areas of concern including gas leak, running toilet, water damage in the kitchen and much more which can be easily overlooked  <br /> <br /> More importantly, he showed me how save a lot of money on utilities bills (electric and water) and  took the time to explain every aspect of the findings. Frankly, this inspection was like a training session for me. Robert is knowledgeable and passionate about what it does. <br /> <br /> I will do business again with Robert and Highly recommend him to every one."

"I sent a text to Mitch late on Thanksgiving eve. Mitch responded early in the following morning and was available for the inspection the following day at my requested time despite this being the Thanksgiving weekend. Mitch arrived with his assistant on time and spent three full hours for all the inspections requested. He was professional and polite. He pulled me a few times during the inspection, showed what he found and explained in detail what could be the potential issues in the future. He covered everything that I wanted to focus on including Roof, Deck, Windows, HVAC, Mold, Termite, Radon and the overall house. I also received the general report and Radon report quickly and on time. I would recommend Mitch to any one who wants to have a thorough inspection of the house. He has good knowledge and experience and gives you an honest opinion of the house. His report also includes the details along with all the pictures and recommendations which will help you make a final decision."

"I called Highland Home Inspections when I thought I might benefit from a radon test. I chose them based on their Angie's List reviews -- and am I glad I did! They actually told me that I didn't need a radon test for what I wanted and gave me a much cheaper solution. This made them no money at all -- and they could have had me easily pay for the radon test by simply keeping quiet (which another inspection company tried to do, by the way.)I found them so honest -- and I will DEFINITELY use them in the future if I need any kind of inspection. Thank you, Highland Inspection, for saving me some money!"

"I received my radon results in a timely manner. I did not hire them specifically, (so, I cannot say I would hire them again) the local company contracted them for this service. The home inspector I hired, handled this service for me and included the results in his report."

FAQs for radon gas abatement projects in Towson, MD

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.
