Why Must Radon Be Vented Into The Air Above My Home’s Roof?2021-11-01T08:07:16-04:00

Radon gas is approximately 7.5 times heavier than air. However, it is a noble gas with no chemical affinity but is easily influenced by air movements and pressure.

In a house with forced-air heating and cooling, radon gas can easily be distributed throughout the entire dwelling. When radon gas is discharged via a radon mitigation system above the roof, the radon concentration falls off dramatically with distance from the point of discharge. The radon gas concentration approaches background levels at 3-4 feet from the discharge point.

EPA disallowed ground-level discharge of radon primarily because of the potential for re-entrainment of the gas into the house and because of the possibility of children being exposed to high radon levels. In addition, the concentration of radon gas at the discharge point can be tens of thousands of picocuries per minute.

How Much Can A Radon Mitigation System Cost?2021-11-01T08:07:17-04:00

You have tested your home for radon, but now what?

If you; have tested your home for radon and confirmed that you had elevated radon levels, 4 picocuries per liter in the air (pCi/L) or higher, our guidance can help you:

  • Select a qualified radon mitigation contractor to reduce the radon levels in your home.
  • Determine an appropriate radon reduction method.
  • Maintain your radon reduction system.

Radon reduction systems work. Some radon reduction systems can reduce radon levels in your home by up to 99 percent.

Most homes can be fixed for about the exact cost as other common home repairs. However, your costs may vary depending on the size and design of your home and which radon reduction methods are needed.

How Do I Know If My Radon Mitigation System Is Working Properly?2021-11-01T08:07:17-04:00

There are several ways to lower radon levels in your home. Some techniques prevent radon from entering your home, while others reduce radon levels after it has entered.

EPA generally recommends methods that prevent the entry of radon. Soil suction, for example, prevents radon from entering your home by drawing the radon from below the house and venting it through a pipe, or pipes, to the air above the house, where it is quickly diluted.

Similar to a furnace or chimney, radon reduction systems need some occasional maintenance. It would be best to look at your warning device regularly to make sure the system is working correctly.

Fans may last for five years or more (manufacturer warranties tend not to exceed five years) and may then need to be repaired or replaced. Replacing a fan will cost around $200 – $350, including parts and labor. It is a good idea to retest your home at least every two years to be sure radon levels remain low.

How To Get Rid of Radon2021-10-05T14:31:04-04:00

Here are many ways to test your home or a building and begin the mitigation process.

If you doubt that your building has a Radon problem, then the best option is to go for Radon testing. You can find a professional and reliable company for the testing and mitigating process. They can better help you in getting rid of it, depending on the concentration.

Does Radon Affect Health?2021-10-05T13:55:46-04:00

The answer is yes! It can pose a serious health risk to your overall health and especially the respiratory system. If you’re exposed to Radon’s excessive level for an extended period, you could have higher chances of developing lung cancer. According to the EPA Radon is the number one cause of lung cancer among non-smokers in the U.S.. This is a silent killer, and you can’t figure out its effects until it’s too late.

Where Is Radon Found?2021-10-05T13:56:56-04:00

It’s a naturally occurring radioactive gas from the natural breakdown of uranium (radioactive decay). Radon is typically found in soil and igneous rock, and sometimes in water as well. It can be found across the U.S., especially in central Kentucky. Radon quickly dilutes when it releases into the air. As a result, it seeps into buildings through gaps, cracks, and holes.

Natural Sources of Radon

There are multiple natural sources of Radon; some of them are as follow;

  • Uranium Ores: It’s found in many soil deposits globally.
  • Shales: It’s a sedimentary rock that is formed from clay and mud.
  • Igneous Rocks: Rocks that are formed from lava or magma cooling (graphite).
  • Phosphate Rock: it contains a higher amount of phosphate level, commonly found in clay.
  • Metamorphic Rocks: rock that forms due to the transformation of other rocks forms (marble).

Limestone is also listed down in Radon’s natural sources, but we can’t accept a high level of Radon produced by its decay. An important thing to note is Radon doesn’t result from the decay of natural sources but through different manufactured structures.

Although Radon is primarily found in outdoor air, it becomes more of an issue when building through the basement walls or floor. This is because it usually moves up through the ground to the air above and into your building through cracks and other holes in the foundation. As a result, your home can easily trap Radon inside, where its concentrations can then build up.

Radon in Drinking Water

If the drinking water is exposed to any level or amount of Radon, it may still be considered dangerous for your health. Yes, if the drinking water source is in contact with Radon containing soil, it can easily dissolve in the water. From there, it could enter your home. A standard safe limit is 2.6pCi/L, and if the Radon level goes beyond this, it can pose a severe health threat.

Can vacant houses be tested for radon?2021-10-05T11:36:11-04:00

Yes. Radon levels in a home, under typical operating conditions, will commonly reach a steady state with mild fluctuations about 12 hours after the house is closed up. Vacant houses will experience factors that may drive radon levels to lower or higher than normal averages, but the effect cannot be predicted. If the house is opened up for ventilation purposes prior to the test, it should then be closed up and a test started no sooner than 12 hours later. If short-term radon testing is being used, then the house has to be kept closed except for normal entry and exit, as if it were the winter heating season. It is recommended that the home’s heating and cooling system be operated normally for the season. If the average indoor level is 4 pCi/L, then it is expected that the radon level will be near to that average after 12 hours of a house being closed.

I’m selling a house. Should I have it tested for radon?2021-10-05T11:36:12-04:00

The homeowner of a house can test their home prior to listing the home for sale. If the homeowner does perform a radon test, most if not all states will require that the test result be disclosed on the whole house disclosure form you will fill out with your realtor. If the initial test by the homeowner comes back less than 4 pCi/L, potential buyers may still request an additional radon test as part of their home inspection. If an initial radon test by the homeowner is 4 pCi/L or greater, the issue will need to be addressed in the real estate transaction. A buyer may want to have a confirmatory test conducted. With an average radon level of 4 pCi/L or greater, it is recommended that a radon mitigation system be installed prior to placing the house on the market, to bring the radon level to less than 4 pCi/L.

I’m buying a house. Should I have it tested for radon?2021-10-05T11:36:14-04:00

The EPA recommends that all houses, regardless of what radon zone the house is located in, be tested for radon during point of sale. The most common procedure for radon testing during real estate transactions is for the potential buyer to request the radon test as part of the overall home inspection. The radon test is generally a separate service and must be requested. If the radon test is 4 pCi/L or greater, the EPA recommends the potential buyer negotiate with the seller to have a radon mitigation system installed with the stated goal of bringing the radon level in the home below 4 pCi/L.

How Does Radon Get into a House?2021-10-05T11:36:18-04:00

There are many ways Radon can get into your house including drains, sump pumps, basement floor cracks, basement wall cracks construction joints, loose pipe fittings and exposed soil. Radon might also enter the air of a home from well water.

Because radon is a gas, it can easily spread from the ground into the air in a home. The main method in which radon enters a home is through the basement floor including crawl spaces.

Can Radon Cause Lung Cancer?2021-10-05T11:36:18-04:00

Yes. The EPA estimates that over 20,000 preventable deaths in the U.S. can be attributed to exposure to radon decay products. That is twice the amount of drunk driving fatalities each year.

Alpha particles released by radon decay products are the main driver in damage to healthy lung tissue. Smoking combined with radon exposure is especially risky.

What Is Radon?2021-10-05T11:36:19-04:00

You can’t see, smell, or taste radon. However, it still might be an issue inside your house. Radon is a gas atom, and it features a half-life of only about 4 days. Radon gas is completely natural and it forms during the decay of uranium-238, an element that is naturally present in our soil.

The seller of the house I want to buy disclosed a radon level of 2. Should this be a deterrent to buying?2021-10-05T11:36:20-04:00

This level should not be a deterrent to buying a home. In fact, any level should not be a deterrent to buying a home because radon can almost always be reduced in a home, and to levels below the EPA guideline of 4. Many times post mitigation tests are in the range of 1-3. The level of 2 would be a very good result for a home that had a mitigation system installed to reduce the level from a much higher number. As long as the issue is resolved in the real estate transaction, the radon level should not be a deterrent to buying any home. Achieving lower radon levels when the starting concentration is between 2 to 4 is not likely to be something a radon contractor would guarantee under typical conditions for a set price.

What information is available regarding radon and real estate transactions?2021-10-05T11:36:20-04:00

The EPA publication Home Buyer’s and Seller’s Guide to Radon details several aspects related to radon testing during real estate transactions. You can find information on radon, the protocols for radon testing during real estate transactions, and guidance as to how to interpret your radon test results.

Brenda M., Lexington, KY

I cannot speak more highly of Wilson and his team. I had a difficult situation with a large crawl and I wanted only one system. Other radon companies kept saying I needed two systems. Wilson and his crew made it work. I went from radon levels of upper 40s to 0.5. I had about 5 companies come through and Wilson and Radon Delete with his HVAC experience and mechanical design training were far and away the most qualified!

James H., Lexington, KY

We had a fantastic experience with Radon Delete. The entire process from quote through install and follow up was seamless. Great customer service accompanied by a high level of craftsmanship is hard to find these days and these guys outperformed expectations at every turn. They were very thoughtful on how to make the system look as atheistically pleasing as possible and our radon levels were cut down dramatically after just a few hours of running the system.
