"<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 />"

"If I could use only two words to describe Craig Kripas (owner) I would say trustworthiness and excellence. <br /> He and his workers (foreman Edmondo, and the other three) were hard working, honest, and did an incredible professional job for a fair price. They know their business, (Check out their website, it is educational, allowing you to read up and understand what Craig and crew are going to do to waterproof and make your home safe and healthy), and they do not cut corners on doing it correctly. <br /> I was married to a subcontractor for 18 years, and this is the first professional (Craig Kripas) whose work-ethic and excellence are comparable to my former husband's- who was without equal in his line of work: cabinetmaking and finish. <br /> BEFORE: Craig came and crawled through my crawlspace, took photos, uploaded them unto his laptop, and explained what needed to be done. He sent me an estimate that night via email. My crawlspace had cracks, leaking water, was moist, insulation was wet and falling down, the light plastic that the former owner had laid in the crawlspace was not taped at the seams, and had pools of water where the ground underneath it was not level. There was junk thrown in my crawlspace, no sumppump or electrical hook up, and mold. <br /> AFTER: Craig and crew were able to finish in 3 days, which was a window when the weather held out a little less than that time in early February. They  leveled the crawlspace ground, reinforced any floor supports that needed (in my 1938 bungalow), dug trenches and laid drain and installed the sump-pump, then went on to shovel and level rounded stone gravel (that does not puncture the 6 mil plastic overlay), to make it easy to crawl through. I went and inspected with Edmondo, and crawled through the crawl space. It was clean, dry, and even cozy, although a little clausterphobic for my taste. <br /> They dug window wells, and replaced the old ones, repaired the brick on the exterior around the window wells, repaired the brick around the entrance to the crawl space, built a new hinged hatch and installed it, graded the landscape so that the water ran away from my home, extended the downspouts, and probably a hundred other things that I didn't notice. <br /> OVERALL: I have never been more pleased with work done, as well as their polite, thoughtful approach. (I did not feel pressured in any way, Craig is soft-spoken, and explained and gave me choices on how he could fix the problem/ and costs per task, if I needed to do it in stages or only wanted to do the minimum).  <br /> Kraig Kripas and his crew are professional, trustworthy, do excellent work, and delivered beyond my expectations, which is a difficult thing to do. <br /> <br /> <br />"

FAQs for radon gas abatement projects in Grantsville, 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.
