Residential Radon Mitigation Systems
Customizing a System For Your Home
Residential radon mitigation systems start with getting radon out of your house through a process called soil depressurization. The goal of depressurization is to draw radon-containing gas away from the house foundation before it even gets into the house.
The mechanics of depressurization involve the use of a fan which creates the necessary suction to vent the radon gas to the exterior of the house. This approach is referred to as active soil depressurization (ASD) and constitutes the vast majority of soil depressurization systems that get installed in home today.
Different Techniques for Different Homes
For Homes Built on a Slab
Sub-slab Depressurization involves cutting at least one 4 – 6″ hole through the slab. A small pit is hollowed out beneath the hole and a PVC pipe is inserted. This pipe is routed to a fan that creates a vacuum beneath the slab. A single radon vent pipe is often all that is required in a residence. A general “rule of thumb” suggests the use of one vent pipe for roughly every 2,000 square feet of floor space at ground level. The number of suction points depends on the permeability of the soil beneath the slab and the number of footings within the building.
For Homes with a Crawl Space
Crawl space depressurization helps reduce moisture in the crawl space. A length of perforated pipe is laid on top of the soil running the length of the crawl space. The pipe will collect the radon from beneath the plastic sheeting when connected to a fan. Perforated pipe used to collect soil gas is laid on the floor of the crawl space. A high density, cross laminated polyethylene sheeting is then laid on the soil. This type of sheeting is very durable and resists tearing.
Block-Wall Depressurization
With this method, at least one four to six inch hole is cored (drilled) through the slab. A small pit is hollowed out beneath the hole and a PVC pipe is inserted. This pipe is routed to a fan that creates a vacuum beneath the slab. A single radon vent pipe is often all that is required in a residence. A general “rule of thumb” suggests the use of one vent pipe for roughly every 2,000 square feet of floor space at ground level. The number of suction points depends on the permeability of the soil beneath the slab and the number of footings within the building.
Drain Tile Depressurization
Homes that have sump pumps or French drains for control of rainwater can be effectively mitigated utilizing the sump to collect radon from the underlying soil. Two types of drainage systems can be readily adapted to collect radon from the soil below a house and exhaust it safely outside. When the drainage system includes a sump, a lid with vent piping is placed on the sump pit. A radon fan connected to the vent pipe is used to draw radon from the soil and through the sump, to an outside exhaust point above the home’s roof. When placing a lid on the sump pit, it is important to remember to allow for future removal of the lid to allow servicing of the sump pump.

First time dealing with Cook's Radon mitigation & the experience was great. Professional, on time, organized & true craftsmen with their work scope. As a general contractor & Certified Professional Home Builder, it's good to know who these folks are & I will definitely be using them again.
Great service with integrity!!! I was interested in adding an additional system in my basement strictly for my peace of mind. They gave me a better and cheaper option by upgrading my current system.
Cooks is the absolute best. I had a client who needed a system. But not only a system but a great system. The crew arrived and provided a great system. The best part of their work is that they will install it where it doesnt even look like its there. Super neat, and clean. They were really really awesome. Their was a closing dependent on the radon system and they reacted fast and the system worked and cleared the radon from the property really fast. Thanks Cooks
I've been extremely impressed with every aspect of Cook's Radon, and will recommend them to anyone without reservation. Tony met with my general contractor to give us an estimate within a few days of my request. My contractor had nothing but positive things to say about the plan moving forward; the design for mitigation and the cost estimates met his requirements right away. He is very particular about any subcontractors working on his projects because he demands a superior product. Paul and Ron showed up on time and ready to jump into the work. I was happy that they knew the plan and understood the science behind their work, as well. Within a few hours the project was complete. Everything that they did was exactly as promised, works as it should, and it looks great. It's obvious that the company believes in great customer service, and I would hire them again if I need another structure mitigated.
