What happened with radon?
Every radon call starts a little differently. Pick the situation that sounds closest, and we will help you figure out the next step.
My radon test came back high
Bill can look at the house, explain the system plan, and give you a clear price before the work is scheduled.
Start here →I am buying a home
Get a real quote during your inspection window so you understand the cost, timing, warranty, and system you will actually own.
Buyer next steps →I am selling a home
Call early, keep your options open, and take radon off the repair list before closing pressure builds.
Seller next steps →I am helping a client
Buyer side and listing side need different next steps. Pick the right path and know what to send Bill.
Realtor help →My radon fan is noisy or silent
Send a photo of the fan or manometer. Bill can usually tell whether the system is pulling suction or whether the fan should be checked.
Fan replacement →I have a pipe but no fan
Newer homes often have passive radon piping. Bill can check whether activation is the cleanest next step.
Passive activation →My radon pipe is in the way
Finishing a basement, remodeling, or adding on? An existing system can often be relocated or rerouted instead of torn out and started over.
System relocation →Experience you can count on
That experience matters because homes are not all built the same. Finished basements, crawl spaces, additions, split levels, passive piping, and existing systems each require a different plan. Bill looks at the home before quoting so the system can be designed around the house instead of forcing the house around a standard layout.
Why homeowners call Bill
Five-year complete fan replacement coverage. If a fan we install fails during the first five years, we replace it at no cost to the homeowner. The service visit, labor, and replacement fan are all included. A replacement fan installed under warranty receives its own five-year term.
Already have a radon system?
You do not have to know who installed it or exactly what is wrong before calling. American Radon Systems checks, repairs, activates, reroutes, relocates, and improves existing systems throughout the communities we serve.
Radon showed up during a home sale?
Buyer side and listing side need different next steps. We keep both paths calm, practical, and focused on a clean system with paperwork the file can use.
Buying with a high radon test
Use the inspection window to understand the real cost, timing, and system layout before closing.
Buyer path →Selling after a high radon test
Call early, get a plan, and keep flexibility before radon becomes a last-minute closing problem.
Seller path →Realtor or agent
Buyer agents and listing agents usually need different next steps. Pick the side of the deal.

Check fan replacementHave a radon pipe but no fan?

View All ServicesExperience with the way suburban homes are actually built
Radon systems are not designed from a single template. A finished basement needs a different route than an open utility room. A basement and attached crawl space require separate suction areas. Additions, split levels, slabs, walkouts, lookouts, passive piping, and existing systems all change the plan. Bill evaluates those details before the system is quoted.
A basement and an attached crawl space require separate suction points or suction areas. The design decision is how those components are routed and connected, not whether the crawl space can be ignored.
In finished or higher-detail homes, routing, paint color, fan placement, sound, and the view from the street may carry extra weight. Those considerations can be addressed during the design instead of after the system is installed.

If a fan we install fails during the first five years, the service visit, labor, and replacement fan are included at no cost to the homeowner.
What the System Is Actually Doing
Radon is measurable and fixable. These two views show why testing matters and why a mitigation system is designed around the whole home, not just one visible crack.
Pressure under the home finds small openings
Radon usually is not coming from one single hole. Pressure under the home lets soil gas move upward through porous concrete itself, sump openings, crawl spaces, cracks, and small gaps around pipes.
The fan creates the easier path out
A mitigation fan creates a lower-pressure path under the home, so radon is pulled into the pipe before it enters the living space, then vented above the roofline.
From the First Call to Done
Bill evaluates the home and helps plan the system. Jose and the installation team bring that plan to life through clean routing and focused workmanship. Most jobs are finished in a single visit. Here's how it goes, step by step.
Bill studies the home and helps plan the system. Jose turns that plan into clean, careful workmanship.
