For over Two Decades, Radon Survey Systems Inc. has been reducingradon levels safely in homes. Thousands of homes have been tested and a large number of homes have also been successfully mitigated by this firm. This unsurpassed knowledge and data base was produced by RSS's determination and strive for excellence for the past 23 years. No other company has the expertise and research data of this particular region quite like RSS Inc.

How expensive is Radon Mitigation?

The EPA has said that fixing a home generally ranges form $500 to $2500. At RSS Inc. the $500 range is typical for passive radon mitigation and is in most cases simple sealing and caulking and or covering of Sump Pumps in basements today. The higher end of the price spectrum is basically talking about active radon mitigation.

RSS Inc. has been offering both types of mitigation for over two decades and would be more than happy to answer any further questions about this topic. (800-883-4760)

How Does Radon Mitigation work?

The majority of radon mitigation systems today address the air pressure differences between the soil beneath the home and the property itself. The objective is to reverse the air pressure relationship and change the house from being a negative air pressure to the soil to becoming a positive pressure to the ground beneath.

How many different types of Radon Mitigation are there?

There are many different types of Radon remedial work. There can be a Passive system which involves some minor steps to reducing radon levels in a home.These could consist of sealing and caulking cracks in the foundation or covering holes or any potential radon entry route like a drain in the floor or a sump-pit. These types of modifications to a basement's foundation typically do reduce the levels to a minimal degree however for higher radon levels, an Active system should be installed.

What is the difference between passive and active radon mitigation?

The main difference is that passive mitigation is remedial work done without the use of a fan. This would then mean that active radon mitigation is a system that has an active fan pulling the gas out from under the home to the outside atmosphere.

What are the different types of active radon mitigation?

  • Active Soil Depressurization (ASD)
  • Subslab Depressurization (SSD)
  • Submembrane Depressurization (SMD)
  • Sump Pump Depressurization (DTD)
  • Drain Tile Depressurization (DTD)
  • Baseboard Depressurization (rarely used today)
  • Block Wall Depressurization (BWD)

What is Active Soil Depressurization?

This is basically the reversal of the air pressure relationship between the indoors and the soil using any of the mitigation systems available today.

What is Subslab Depressurization?

Mitigating radon using this technique involves an active fan which pulls radon from under the slab and exhausts it to the outdoors. This system is most frequently used and has a very high percentage of correcting the problem.


This is a example of what the vent pipe looks like in a Subslab Depressurization System today. What is Submembrane Depressurization?

This type of remedial work uses suction created under a membrane, such as plastic sheeting or polyethylene on exposed soil or rock. The radon is then collected and exhausted to the outdoors. In some instances this type of system can be combined with other types to increase the efficiency of a system in reducing radon levels further.

What is Sump Pump Depressurization?

This system is used frequently when there is a home with a Sump pit. The pit usually has drain tile from the perimeter of the house which all drains into the sump. RSS Inc. first will cover the sump pit opening with an air tight cover which does have a removable section if the pit is ever to be accessed for repair. Then the actual vent pipe is installed into the sump pit and the radon is exhausted from all around the perimeter of the home to the outside.

What is Block Wall Depressurization?

This technique utilizes the hollow block walls of a basement. The vent pipe is inserted into the wall and the radon is then exhausted from the walls of the home. This type of system is rarely used by itself but can often be used in combination with other systems.

How do i know if the radon system is working properly?

RSS, Inc. performs post mitigation follow up testing in a home after the remedial system is installed. This follow up testing will show the homeowner what the radon level is now concentrated at. Almost all systems installed are guaranteed to correct the radon level in a home and lower it to an acceptable level set by the EPA (4pCi/L). RSS has a variety of warranty options that can be further explained by calling our toll free hotline at: 800-883-4760 * All systems installed should have a system indicator. These can be in many forms from manometers to a electronic monitor both available through RSS, Inc. The visual indicator's function is to show that the Radon Mitigation system is moving air through the pipe.It does not demonstrate what the actual radon level is. Every home should be tested for radon every two years according to the recommendations of the EPA.

This is the visual indicator used to show air flow by RSS. Inc. The U-Tube Manometer is most frequently used.

What does a typical Radon Mitigation System look like from outside?

Here is a picture of a system currently in operation. This particular radon mitigation unit is an external mounted system. This means that the fan or active motor of the system is mounted on the outside of the home.

This is an external mounted radon mitigation system installed in 2000 By RSS Inc.

What does an attic mounted system look like from the garage?

Here are a few pictures of an internal or attic mounted radon mitigation system. All parts are identical to the external mount however the routing of the pipe is from the basement into the garage and from there into the attic above and out the roof using a roof boot to prevent leaking.

Here is what the attic mounted system looks like from your garage, also there is a system indicator called a manometer or U-tube which can be monitored daily

What does a radon mitigation system look like when exiting a home?

* Most of the systems installed when going through the attic do not have a cap or grate on them so that it can blend in and look like a regular outlet. * Caps, grates, and other end pieces can be installed per customer request for aesthetic preference or appeal.

This is the roof boot used to exit a property with the radon pipe. Rss can paint the pipe black to blend in better with the surroundings per costomers request.. Other caps and grates can be installed per customer request as well.
