Residential Radon Mitigation

Sub-slab Depressurization Radon Mitigation Systems

With a sub-slab depressurization system, we will core out a small opening in your foundation. Then we can dig out enough dirt to create a vacuum underneath the slab with the installed radon fan. This vacuum causes the radon to travel to the path of least resistance, which will now be our suction hole. We will then continue to run the piping to the exterior of your home, where it will be safely discharged.

If there are any large openings in the foundation, large cracks, or gaps in the floor-to-wall joints, they would all need to be addressed to ensure that we have no loss of suction. The system only works if we can keep the vacuum at a high level underneath the slab.

Sump pit Suction Radon Mitigation Systems

A sump pit suction system is an extremely effective radon mitigation system. We will install the suction pipe into the lid of your sump pit. We will then seal off the sump lid and around the pipe so that it is airtight. This then begins to draw air through the drainage pipes that run beneath your foundation, giving us resistance-free air flow and removal of radon.

We will also install a viewing window on the lid of the sump pit so that you can monitor the water activity inside the pit. If your sump pit is active and has a sump pump installed, you will eventually need to access that pump to replace it. So we have designed our mitigation system to be completely removable so that you will be able to access the pump whenever you need to.

This method of mitigation will, in no way, negatively affect your sump pit or sump pump system. The mitigation system works in line with the existing sump pit and pump.

Pre-existing Passive Radon Mitigation Systems

A pre-existing passive radon system is a perforated piping system that would have been laid under the foundation when your home was built. This is generally only in newer homes, 2013 and forward.

If your home has a passive radon system, many times you will still need to add the additional piping, suction fan and exterior exhaust to mitigate the home.

Never assume your home is free of radon; testing is the only way to know if you have a radon problem.

Crawl Space Depressurization Radon Mitigation Systems

If your home has a crawl space, it may need to be sealed with a vapor barrier to reduce your radon levels.

When there is a sump pit, we are often able to reduce the radon levels without sealing the crawl space because we can pull so much air from beneath the surface that it does not allow the radon to move up through the crawl space and into your home.

We seal your crawl space using heavy-duty 6-mil plastic and a premium construction adhesive to bond the vapor barrier to the foundation walls. This will prevent any radon, air, or moisture from passing through the vapor barrier. When we pair the sealed vapor barrier with a core penetration, sump pit suction, or crawl space depressurization mitigation system, we are able to cause the air, that would naturally travel through the crawl space to be pulled to our suction point and then exhausted outside.

Every home is different, many factors will dictate whether or not your crawl space will need to be sealed. Since it is sometimes needed and sometimes not, we offer you a phased system approach. We would only do one step at a time until the desired radon levels are achieved. This can potentially save you hundreds, even thousands depending on the size of your crawl space. Our experienced technicians will walk you through your options upon arrival at your home.

Radon Mitigation Pipe Exhaust Extensions

The AARST/NEHA regulations and guidelines cover strict rules on radon mitigation systems. As certified and licensed radon mitigators, we follow these codes and help homes and businesses do the same. This helps you stay safe and avoid fines. Over the years, the codes have been updated and pipe exhaust regulations have been changed. Your commercial or residential property may require tweaking to adhere to the new guidelines and codes. The new update states that your exhaust piping needs to go all the way to the roofline. If you have an older system that does not have proper exhaust piping, we can help. APEX Radon offers pipe exhaust extension installation in the Denver metro area, so you can rest easy knowing that your family is safe from this dangerous gas.

Radon Mitigation Exhaust Pipe Installation

When you install a radon mitigation system in your home, one of the most important components is the vent pipe. This pipe helps to remove radon gas from your home and release it into the atmosphere, where it poses no threat to your family. The size of the vent pipe and the type of material it’s made from are both important factors to consider when you’re choosing a pipe for your home. APEX Radon can help you select the right pipe for your needs and install it correctly.

The Importance of Radon Mitigation Exhaust Venting

When you’re installing a radon mitigation system, it’s important to make sure that the exhaust pipe is properly installed. The pipe should be the right size for your home, and it should be vented to the outside. This will ensure that the gas is effectively removed from your home.

Radon Vent Pipe Guidelines

If you’re installing a radon mitigation system in your home, there are some guidelines that you should follow to ensure that the system is effective. Are you not sure if your radon mitigation system is up to EPA code? Read through these requirements. If you’re still not sure, contact our team for an in-depth inspection.

• Vents must be above the roof surface.
• Vents must be 3m or greater above the ground.
• If vents are not at least 0.6m above windows, doors, or other openings that could allow radon to reenter the home, they must be at least 3m away from such openings.
