Our levels were at 12 and now they are consistently at .5 (Under 4 is acceptable) We now feel confident using our basement again. That peace of mind is priceless. We also appreciated how Tim kept us updated via email and text regarding our appointment. He is very easy to communicate with. I would highly recommend Radon Mitigation of Maryland! ~Mike & Lorri Saintcross

fast, efficient, professional. removed asbestos tile from entire lower floor of an older house…read more (kitchen, living room, two bedrooms, utility room). price was on the lower end of the estimates we got, but we chose them because of their prompt replies and experience in asbestos removal. we emptied had emptied out the house and were really ready to get the ball rolling and they squeezed us in within a week, and their crew took two days to complete the job. they were the second company to book an in-person visit and get us a written estimate, plus they were very responsive to calls and emails. seemed an excellent value for an experienced crew. they sealed area off with plastic and negative air pressure, and used a wet method to remove the tile (thereby avoiding dust). after tile removal, they sealed the concrete subfloor with to trap the remaining mastic residue that was stuck on the concrete. the sealant was almost like a rubbery latex paint (we later installed a vapor barrier and vinyl plank to finish the floor). afterwards there was a strong smell of the sovent and the sealant they used and it took several days of airing out for this to mellow. it smelled like pine or turpentine. no damage, but there were quite a few staples left in the wall from when they installed the plastic barriers-- very inconsequential and easy to remove. we had planned for repainting the walls anyway. realistically one of the best experiences with a big job using a contractor like this!

John and Lawrence arrived punctually and brought drop cloths and wore temporary shoe booties which I found impressive. These gentlemen brought the equipment into the house and did a thorough job.

They answered all of my questions. At the end, they vacuumed the areas where they had been working to ensure that everything was left in great shape. I recommend this company.

Even though he wasn't home at the time I wanted to make sure any other pet would be 100% safe. I remembered my neighbor telling me a house that sold recently had a high level of radon. After getting the machine it was determined we had it as well. I figured I would call around for estimates but after having Radon resolvers come out and check things and let me know how much it would be I was ready to go immediately. I had also gotten a few recommendations from other neighbors from this company so that was an added plus. After putting down our deposit they were able to come out the following week. They didn't play. They came, did the work and showed us how everything worked and we paid them the remaining balance and they left. I feel safer and happy with this company. They were very professional and went over everything prior to digging and drilling. They even had to extend the pipe due to a change in the placement and they didn't try to up charge us. We are very happy and thankful to have had them do the work. 100% recommend!!!!

I recently decided to tackle our radon levels and purchased a monitoring device. Initially, I found…read morethat the readings fluctuated between 2 pci/l and 4 pci/l, especially with the basement window open. After a heavy rain, I was alarmed to see the levels spike to 9 pci/l. Since we have a room converted into a remote office in the basement, resolving the radon issue became a priority. After doing some research, I discovered that Ric had a remarkable number of 5-star reviews compared to other companies, so I reached out to him and set up an appointment. Ric showed up right on time at 8:00 AM and got straight to work. The first thing he did was identify the best spot in our unfinished basement for drilling a hole. He chose a discreet location behind the laundry room door, ensuring it wouldn't be noticeable. Ric then carefully brought in several buckets of gravel and soil under the slab, installed a white PVC pipe, and extended it into the garage. From there, he routed the pipe up into the attic and out through a small hole drilled in the siding of the house. He worked diligently for six hours and did an impressive job. Ric made sure to clean up thoroughly after finishing, and he sealed the slab crack with specialized radon chalk. The next day, with the basement door and windows tightly shut, I was thrilled to see the radon levels drop to sub-zero. I monitored the readings for three weeks, and they remained consistently low. I can't believe Ric doesn't have even more 5-star reviews; he truly did an outstanding job!
