Common techniques include: Sub-slab depressurization, where suction pipes are inserted through the floor or concrete slab into the concrete slab below the home. A radon vent fan then draws out the radon gas and releases it into the air outside. This is the most common type of system.
Can radon be remediated by venting?
In some cases, radon levels can be lowered by ventilating the crawlspace passively, or actively, with the use of a fan. Crawlspace ventilation may lower indoor radon levels both by reducing the home’s suction on the soil and by diluting the radon beneath the home.
Can you vent radon out the side of my house?
The vent pipe discharge point is under the overhang and approximately 3 feet from the window. EPA’s Radon Mitigation Standards require vent discharge points to be above the roofline, and no less than 10 feet sideways or 2 feet above any windows or vents.
Should you walk away from a house with radon?
Should you walk away from the deal? Consumer Reports says you don’t have to. Radon-related deaths are due to exposure over the course of a lifetime. “You should definitely take it seriously but you really don’t need to walk away from the home.
What is the best way to mitigate radon?
Other radon reduction techniques that can be used in any type of home include: sealing, house or room pressurization, heat recovery ventilation and natural ventilation. Sealing cracks and other openings in the foundation is a basic part of most approaches to radon reduction.
Should my radon pipe have a cap?
Pipe covers can cause your system to freeze over in the winter: When your radon mitigation system is running, it is pulling air from beneath your homes foundation and safely venting it above your roofline. In conclusion, putting a protective cap on the top of your radon system might sound like a good idea in theory.
Can radon fan be installed in basement?
A radon fan must be installed in a non-livable area of the house. This cannot be a basement or crawl-space area!! A radon fan may be installed in a garage, house attic, or outside the house. The radon fan’s exhaust pipe must be run to a minimum height of 10′ from the ground.
Where should a radon fan be placed?
Radon mitigation standards require that the fan to be placed outside of the living space of the home. Another way to define this is any where outside the conditioned air space of the heating and air conditioning system.
Does sealing concrete help with radon?
It is very important to understand that concrete sealers do not stop Radon gas. Period. There is no super sealer that stops the movement of gas through a porous concrete surfaces. The only way to get Radon out of your basement is with a Radon mitigation system.
Does a concrete slab block radon?
Remember that even several inches of concrete cannot stop radon. Some builders believe that the plastic vapor barrier under the slab will stop radon. Although it is a part of the “radon resistant” construction, it merely reduces the flow of soil gas.
Do radon floor sealers work?
Again, the only way to ensure you are removing radon from your home is with a mitigation system. Sealing the basement floor can help, but just sealing the cracks is unlikely to reduce your radon levels in the long term.
What time of year is radon highest?
The reason that radon levels in the home can be higher in the summer and winter is two-fold. During the winter, the air in your home tends to be much warmer than the outside air, and this temperature difference creates a vacuum within your home.
Can you vent radon gas into the attic?
Attic installed radon mitigation systems offer the benefit of hidden system components while protecting the radon fan from the elements. In retrofit situations the attic installed system is usually installed through a garage with the radon vent fan in the garage attic.
Can radon enter through floor drain?
Radon Enters Through Floor Drains Radon gas, insects, sewer gas, and fumes can enter homes and businesses through floor drains or through a sump. Radon gas is a deadly carcinogen. Installing a Dranjer valve in the sump lid and the floor drain may be all that is required to reduce radon to safe levels.
Is radon a deal breaker?
So what is radon gas? You can’t see it, smell it, or taste it, but radon gas is a leading cause of lung cancer, according to the National Cancer Institute. However, the presence of radon in your home doesn’t have to be a deal breaker.
Can radon give you headaches?
The only known health effect of radon is an increased risk of lung cancer. Radon does not cause any warning symptoms like headaches, nausea, fatigue, or skin rashes. If you are suffering from those symptoms or other physical ailments, you should consult your physician.
What are symptoms of radon poisoning?
A persistent cough could be a sign that you have radon poisoning. Persistent cough. Hoarseness. Wheezing. Shortness of breath. Coughing up blood. Chest pain. Frequent infections like bronchitis and pneumonia. Loss of appetite.
Does a dehumidifier help with radon?
No, buying a dehumidifier will not make radon go away. Radon must be removed by a remediation method like active soil depressurization (ASD), which ironically has been shown to be even more effective at removing humidity from a home than a dehumidifier in the same EPA study.
Will running a fan reduce radon?
In some cases, radon levels can be lowered by ventilating the crawlspace passively, or actively, with the use of a fan. Crawlspace ventilation may lower indoor radon levels both by reducing the home’s suction on the soil and by diluting the radon beneath the home.
Can radon pass through concrete?
Radon, soil gasses, and water vapor will easily pass through any openings, cracks, gaps, drains, or thin concrete (rat slabs) in the basement.
