Get matched with top radon gas abatement pros in Crofton, MD

"John and his team were life savers for us- literally! We had hired a different radon mitigation company (nationwide) and needless to say, their system did nothing! I have two little kids and was so frustrated with the levels staying high. I was looking for someone who could possibly repair the existing system which is how I came across radon abatement services. They had videos and pictures on their website, of all the wrong work that was done by contractors. I figured these guys know what they’re doing. And know they did! I had emailed John to tell him our situation and he got back to me and explained everything in detail. He told me what and why our house needed a different system. I had not given him a single penny and he was so gracious to share his expertise with me. Ofcourse, Eventually we hired them to install a new radon mitigation system in our house. Within the day of installment, our levels went down below 4 and have stayed below 2 consistently thereafter. I cannot thank John enough. Their prices were also reasonable. I would give them 10 stars if I could."

"I'm completely satisfied with the work that John's team did. They were extremely professional and knowledgeable. The workmanship is superb. Best of all, the system works as promised and reduced the radon concentration based on subsequent tests. I could not recommend them more highly."

"Outstanding service! I could not understand why my downstairs closet was extremely cold upon entry. During my first conversation with Phillip, he conveyed concern and dedication regarding identification and remediation of the unusually cold air. During initial visit, Phillip noted portions of closet were approximately 15 degrees colder than adjoining rooms. After conducting internal and external inspections of the nearby areas, he identified potential source of cold air. A couple days later with outside temperatures in the 20s, Phillip exhaustively sealed external areas of concern. A few days later, he came again to determine temperature differential within the closet. It was now much more comfortable with temperature only a few degrees below neighboring rooms! Throughout the entire process, Phillip was very friendly and knowledgeable."

"Mitch was friendly as he was professional. The report was thorough and easy to understand, with excellent visuals. Could not ask for a better home inspection!"

"Robert was very helpful, knowledgeable, and courteous. I sometimes felt as if he were inspecting his own home, that's how much care he demonstrated."

"I used this company to perform a home inspection before I bought my house. Due to its negligence and breach of contract, 9 months after I moved in, I had to replace the roof on the house. The company will do nothing to rectify the situation. They are cheats and liars that hide behind their contracts. Their inspectors take every shortcut, and they will not protect you during the home buying process. Just don’t use them."

"I walked through the inspection with Kevin and he did a fine job explaining all his findings."

"as advertised"

"bottom line excellent work, good price, I highly recommend GMD Consttruction. quick response to getting a bid. Installation was done in 2 hours; excellent work; 50 yr caulk to seal the tube opening in the basement floor; electric hard wired into a circuit protected by a generator,; exterior power cutoff, fan and pipe to the roof line installed in a professional manner with secure standoffs for the pipe."

"Robert is FANTASTIC!!! The regulations that a typical home inspector must work by are not as thorough as most home buyers would prefer...luckily Robert is not quite typical. He is thorough to a T exploring the home from basement to chimney top. I would hire him for every home I look to buy in my future. Very confident and happy with his work."
