Radon mitigation typically costs between $1000 and $2500. Here in Minnesota, we find most radon mitigation contractors are charging anywhere from $1500 to $2500.
Be very cautious of low-priced contractors and do your homework.
How Much Does American Radon Mitigation Charge?
Just to warn you, we will be the most expensive estimate you can find. Most of our mitigation systems cost between 3 and 6k.
Why? Because we specialize in one thing and that is to get your radon levels as low as possible. There is no safe level of radon. It is a radioactive gas and we want to reduce your family’s risk. We are aiming to bring your levels below 1 pCi/L.
There is a lot of extra work that goes into being able to achieve this and we spend a significant of time on diagnostic testing and system design.
Things to Consider
There are many factors that determine how much your radon mitigation system will cost. Some of those factors include:
Some cities require a permit for radon mitigation. Permits range from 25 to 150 dollars. Any additions to electrical also require a permit and a state electrical inspection.
Mitigation System Tag
Some states, including Minnesota, require a mitigation system tag. In Minnesota this tag is $75. There is currently an injunction that has this on hold in MN.
Some radon mitigation systems require an electrician to wire the radon fan. If a radon contractor says that he can wire the radon fan for you, find a new contractor! He is probably not a licensed electrician and will not pull a permit. If his work causes a fire, his insurance will not cover it.
If the radon fan is in the garage attic, we can sometimes use the outlet for the garage door opener to plug the radon fan into as long as it’s within six feet of the fan and the ceiling is not drywalled.
Number of Suction Points
The key to getting your radon levels low, is to get suction under your entire home. This sometimes requires more than one suction point. Homes with multiple foundations, additions, and without drain tile often require multiple suction points.
Location of Radon Fan
The location of the radon fan has a large factor on the cost of radon mitigation. Outside systems are cheaper because there is less parts and labor. We try to avoid outside systems whenever possible because they are incredibly ugly, more susceptible to freeze-up, and have a shorter fan life.
A crawl space with a dirt floor can add a lot of expense to mitigating your home. Encapsulation is very time consuming. We often recommend a phased approach of mitigating the lowest level of your home along with retesting the basement and the room above the crawl space to determine if encapsulation is required. Most of the time it is not required to reduce your radon levels.
A home with drain tile usually only requires one suction point and this keeps your cost down. The downside to drain tile systems is that they tend to be very leaky and time should be taken to seal openings at the top of block walls.
Aftermarket drain tile systems are notoriously leaky because of the open gap left between the edge of the floor and the foundation wall. If the opening in not sealed, the radon fan will draw conditioned air that you are paying to heat and cool out of your home. This can also lead to back drafting of your combustion appliances.
Sealing is a great way to increase the efficiency and effectiveness of your radon system. It can also mean a more energy efficient fan may be used and that will save you money over the years.
Dense material under your home like clay or fine sand may require more than one suction point to bring down your radon levels.
Finished basements limit what we can do as far as sealing cracks and openings, vent pipe routes, and suction point placement. Unfinished basements always put a smile on my face.
Post Mitigation Radon Testing
There are a few options for post mitigation testing.
- Hiring a professional to test using a Continuous Radon Monitor. This will likely cost $150 to $250.
- Using a short term radon test kit that you the homeowner set up and mail to the lab. We include this with every mitigation system.
How to Choose a Contractor
If I were looking for an estimate for radon mitigation, I would look for the following.
- A contractor that will come to my home to provide an estimate and explain my options.
- A company that has good reviews.
- One that uses high quality materials.
- Uses products that don’t leave my family at risk to VOC’s.
- One that checks for backdrafting.
- And most importantly a contractor that does diagnostic testing.
We will not be the right fit for everyone. We understand that if you are selling your home and are required to install a radon mitigation system that you are not looking to invest a lot of money into something you won’t benefit from. If you find yourself in this situation, we recommend taking some money off the selling price to allow the buyer the opportunity to have mitigation done the right way.
We truly want to do our very best for every one of our customers. Your family’s health is our main concern.
