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.
