"We used Radon Abatement Services for our basement. The radon levels were slightly over the EPA recommended limit. We mitigated the radon as part of a larger basement renovation. Radon Abatement Services worked with our General Contractor and did a great job. Radon levels are vastly reduced now as a result of their work."

"You certainly get what you pay for! While CSI wasn't the cheapest on our list of home inspection and radon testing quotes, the cost was more than reasonable for the level of service that we received. Ron, our home inspector, was fantastic! He arrived early, and I don't think he could have been more thorough than he was! He was very friendly and personable, and was more than willing to answer our questions during the inspection. He went through the entire home with a fine toothed comb! He pointed out defects that he found, and explained things in detail. He also highlighted the positive things he found. Used a drone to inspect the roof and chimney, and thermal imaging to check for hidden moisture. I feel like we have an excellent idea of the condition of the property we are buying, which has done a lot in making us feel more comfortable! The report we receiced within 24 hours was professional and clearly written with appropriate photos attached. Will certainly recommend to others, and will use them for any future home inspection needs we have!"

"I had a pipe burst in the basement of our rental property, Flood Crew was referred by our realtor. They arrived quickly after the pipe was fixed by our plumber, demoed, and dried out the areas, even handled packing out our furniture and placing carefully in a pod storage while the work was being done. They did mold testing and made sure everything was safe, the best part was that they dealt with the insurance and we didn’t have to do anything."

"Good job working in awkward space with little room to work around radon removal system outlet pipe.
The downside: Area clean up was slightly below average and drywall material was left in splotches on wall (perhaps hard to see because of similar color) and also left few small splotches on floor (not hard to see).
Frankly most contractors do a poor job of protecting your belongings and cleaning up and I should have bird-dogged them more.
Also area of drywall tape near baseboards under window was not covered sufficiently and I had to get them to improve coverage before they left.
The job they did around the pipe was a B but overall, have to give them a C or C+ for quality because of visible tape and splatter issues.
But both men were very nice and polite as was the owner or manager with whom I made the appointment.

FAQs for radon gas abatement projects in Winchester, VA

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.
