Radon Remediation in Arlington Virginia

In Arlington, Virginia, you are likely to fall into Radon Zone 2, and has the potential for radon levels between 2 pCi/L to 4 pCi/L.

EPA guidelines vary depending on the location of your home and the composition of your home. Homes with tighter constructions tend to trap more radon. But regardless of your home’s construction, the EPA recommends you test indoor radon levels, and if needed have a radon mitigation system professionally installed. EPA recommends remediation for your home when the radon levels hit or surpass 4 pCi/l.

Is Radon A Problem in Northern Virginia?

It is estimated that one in every fifteen homes in the US contains elevated levels of Radon. So, it comes as no surprise that recent studies have found that up to 56% of Northern Virginia homes contain elevated radon levels.

While most people don’t get sick immediately from radon exposure, it is still a health risk. Studies show radon exposure is responsible for thousands of lung cancer deaths annually. Some common signals that your lungs have been affected by radon include chest pain, coughing up blood and wheezing.

To prevent the harmful effects of radon, you need to do more than just seal cracks in walls. Radon remediation systems can reduce dangerous levels in your home.

Radon is odorless, the only way to determine if your home contains levels of radon gas is by a simple radon test. The good news is that professional radon testing is inexpensive and easy to do.

Radon Mitigation in Arlington

When levels surpass the EPA recommended radon measurement protocols, you should contact a professional radon mitigation company to install a radon reduction system in your home. Some common techniques include:

Sub-membrane depressurization – this method is ideal for crawlspace foundation types. It involves covering and sealing the open dirt with a plastic membrane and then using a PVC pipe and a vent fan to direct the radon gas outside.
Sub-slab depressurization – in this method, suction pipes are installed through the concrete slab below the house. Professional radon contractors then install a fan to suck the gas under the floor slab and release it outside for quick dissipation.
Heat recovery ventilator (HRV) – this is a machine that exchanges outdoor and indoor air, consequently reducing the levels of radon by dilution.
Sealing sump covers, large cracks, and holes in the slab – this method protects the home from losing vacuum pressure at the vent pipe. However, sealing isn’t sufficient by itself.

Can sealing and caulking my basement solve radon problems?

It’s tempting to get a quick fix like painting, sealing, and caulking to solve your radon problems. However, these fixes don’t effectively reduce radon levels. Radon gas seeps into a building because of the thermal stack effect created by structures on the soil. Also, radon is sucked into the building through small openings and semi-porous materials, including concrete or cinder blocks.

A professional radon abatement service like Radon Defense is the only surefire way to reduce exposure to radon.

Does opening windows or running a window fan reduce radon concentration?

While opening the windows might reduce radon levels in your home, it’s only a temporary situation. Mainly because the source of the radon gas isn’t dealt with and because leaving your window open and running a fan isn’t possible all-year round. After closing the window, the radon gas concentrations will return to their original level after 12 hours.

Running a fan and leaving your window open will only leave you with high energy bills. In the long run, it’s more economical to have Radon Defense install a radon mitigation system in your home. Call us today and our radon technician will be happy to answer questions about radon mitigation and costs. They’ll also explain our installation process and help you schedule a comprehensive radon inspection before installation.

We chose Radon Defense because of its quick response and fair pricing. Linda presented all the options for the Radon mitigation system with photos and clear prices. The technicians were efficient on the installation and let me know the progress of their work. The look of the installed system blends seamlessly with my house. Overall the experience is great and I would recommend them to others in the future. - 9/07/2024

There are many companies that promise things and don't deliver. This is surely NOT one of them. They told me exactly what to expect and what they could do for me. Eric and Nicolas came out to my house. Expected it thoroughly and went right to work. Prior to them rectifying the issue, our radon levels were off the charts. Now our radon levels are almost non-existent. I had one concern after about four months of having the radon pump placed in our home. I called Radon Defense and Paul answered immediately. Unbeknownst to me, my concern wasn't a concern at all and my radon levels were fine. My issue was were addressed immediately and Paul assured me that Radon Defense will be with my and my family forevermore..... So refreshing. - 9/03/2024

The installation crew was great to work with and the installation looks very good. The radon levels measured the day after the work completed decreased. Hoping that trend will continue. - 8/20/2024

Would recommend Radon Defense. Eric, who came to visit - educated us on its operation and provided valuable homeowner tips. Additionally, Linda, the phone representative, is kind and attentive. - 8/13/2024

I highly recommend Radon Defense. From my first call through final installation of a radon mitigation system, they were professional, courteous, patient, and never high pressure. I had to get approval from my homeowner's association, which slowed things down for me, but Radon Defense worked with me and were ready to install the system as soon as I got approval. On the day of the installation, the crew was careful and did a very professional installation and cleaned up the work area. They then walked me through the system, explaining how everything works and what I should look out for to make sure it continues to operate. Communication was always clear and prompt with everyone I interacted with. - 8/03/2024

The Radon Defense team was amazing. Their service was professional, prompt, and made an immediate difference in our basement. They installed a system in our house that required relocating a passive pipe. Eric did an excellent job informing us about the process, installing the system, and educating us about how it worked. Linda effectively communicated with us, giving us estimates and arranging a roofer and electrician to complete the job. I would highly recommend Radon Defense! - 8/03/2024

Linda C.

Prior to moving into our residence, we reached out Radon Defense to do a radon inspection. I am so glad we did because our radon levels were sky high. I contacted Linda and she was wonderful — super nice, responsive and knowledgeable. We ended up also getting a mitigation system installed by the company (they offer various styles depending on preference and price point). Eric and Nicholas assisted with that and they were timely and kept me informed on progress. I’ve had such a pleasant experience with this company, and Paul was super helpful when I had follow-up questions as well. You won’t be disappointed if you go with this company! - 8/03/2024
