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.

Called to get info on remediation issue and felt comfortable enough after my conversation with Monique to proceed with having Cook's proceed with the work. The staff was very thorough, professional and they completed the job in a short time, as quoted with great results. They greatly exceeded my expectations and it is obvious they take great pride in their work and reputation. Would highly recommend them.

We decided to go with Cook's Radon after comparing several radon remediation quotes, all of which were considerably different in terms of fan placement and cost. Tony personally came out and assessed our house and discussed his recommendations. He has been in the construction business for many years prior to his focus on radon remediation and it was clear to us that, because of his experience, he was knowledgeable and well qualified to assess what options would work for us. We appreciated that he came out in person, instead of sending a salesperson to our home. Additionally, his wife Monique handles the administrative side and was consistently so kind and professional over the phone. What initially stood out to me from my conversations with them was that I could tell that they are personally vested in their business and they truly care about their customers and the community. Tony was very thorough and answered all the questions we had. Repeatedly, we heard from other companies that remediation of our house would be challenging due to our basement being almost entirely finished, but Tony seemed confident and his proposal was straightforward. It was also the least invasive out of all of our quotes, and the lowest cost. The level in our basement on pre-test was 8.7 pCi/L. Tony proposed an active sub slab depressurization system with garage routing and guaranteed a level of 3.9 pCi/L or below (with modifications or additional to our system at no additional charge if his proposed system did not achieve this level). His technicians were prompt and respectful and the system looks wonderful, it is not unsightly at all and we barely hear the fan although it is in the crawlspace of one of our upstairs rooms (our fan could not be placed in the attic due to the configuration of our home). Our post-test radon levels for the room in our basement that previously had the highest level on testing came out to 0.8 pCi/L! We are so happy that we chose Cook's Radon and will absolutely recommend them to others.

Tony installed a system for us for a cover-all fee to get radon below limit. It was reasonable as my house took three suctions and diagnostic / radon level was guaranteed. Don't try to save a few bucks and get it done right. Highly recommend!
