“Do I really need two radon systems?”

A Spanish Fork homeowner called us worried. Testing had already confirmed elevated radon in the house, and every quote coming back said the same expensive thing.

The home was about 20 years old with a split-level foundation — the concrete slab sits at more than one elevation rather than as a single flat pour. Every contractor who priced the job over the phone concluded it needed two separate mitigation systems, one per slab section. None of them had walked the property.

The phone quotes “You'll need two systems.”

Two fans, two sets of piping, two roof or wall penetrations, and maintenance on twice the equipment — priced without anyone setting foot in the house.

versus
Utah Radon Defense “Let's go look at it first.”

We drove out, walked the foundation, and mapped where each slab section met the next before quoting anything at all.

What the testing actually showed

From there we ran our standard mitigation process, starting with Pressure Field Extension (PFE) testing. PFE testing measures how air communicates beneath the concrete — whether one suction point can pull vacuum across the whole foundation, or whether a second point, and a second system, is genuinely required.

On this home the testing showed strong communication beneath both slab sections. A single, correctly placed suction point could depressurize the entire foundation. The second system every other contractor had assumed was necessary turned out not to be.

5.0 pCi/L — measured in this Spanish Fork home
Before mitigation · no warning signs

You can't smell it. You can't taste it. You can't see it.

This split-level home tested at 5.0 pCi/L — above the EPA action level, with nothing in the house to warn the family living in it.

Still above 4.0 · still worth fixing

Two contractors said this needed two systems.

Every phone quote assumed the split-level foundation required a second system. None of them had walked the property. Pressure Field Extension testing settled it.

Below the action level · we can do better

Good isn't always the goal. Lower is.

One correctly placed suction point depressurized the entire foundation, venting radon above the roofline before it reaches the living space. Installed in about half a day.

Verified · post-install retest

And this is the number we came back to prove.

0.8 pCi/L — an 84% reduction, from one system instead of two. Backed by our Low-Level Guarantee and a lifetime transferable warranty.

Before and after readings are the verified results measured on this Spanish Fork project — every home is different. Your actual result is verified with a post-install retest. EPA recommends action at 4.0 pCi/L.

What It Means for Your Home

One System, Because the Testing Said One System

Because the diagnostics ruled out a second system, this homeowner avoided the added equipment cost and the ongoing maintenance of running two fans instead of one.

Just use them! I got a handful of quotes for radon mitigation and this company stood out. They were the only company who did in-person quotes, which I loved. JJ is the owner of this small local business and is certified, knowledgeable, and very personal. He looked at our space and gave us a custom quote, advised us on the most discreet placement, pipe size, and answered all of our questions. Most companies give you a one-size-fits-all generic quote from a salesperson (not the technician) without even coming out. JJ was very communicative through the entire process, on time, and did clean, fast work. I liked that they did small tests first to make sure the air was actually moving before putting the entire system in. I was impressed with how respectful they were of my home — they put down carpet covers and wore shoe protectors the entire time. Pricing was competitive. I would totally use them again and 100% recommend.

Older Homes and Complex Foundations Need an In-Person Look

A 20-year-old home has usually settled, been added onto, or had foundation work done that isn't visible from a listing photo. Split-level, walkout, and multi-elevation foundations are exactly the layouts where a generic quote is most likely to be wrong — in either direction.

This matters for home buyers and sellers working through a transaction on an older Spanish Fork property, for home inspectors who need a contractor that won't over-scope a job to be safe, and for builders planning systems into new construction.

Most Spanish Fork homeowners land in the $1,700 to $2,500 range, with many projects closer to $1,800 to $2,000 — see the full breakdown of radon mitigation pricing across Utah. A split-level foundation is one of the layouts most likely to push an estimate higher, mainly because it's the one most often assumed to need a second system.

Questions Spanish Fork Homeowners Ask

Will a split-level foundation need two systems? +
Not necessarily. It depends on how much the slab sections communicate beneath the surface, which is measured with Pressure Field Extension testing. On this project, testing showed one system could treat both slab levels.
What radon level requires mitigation? +
The EPA recommends mitigation at a confirmed level of 4.0 pCi/L or higher. Some homeowners choose to mitigate between 2.7 and 4.0 pCi/L for extra peace of mind. This home tested at 5.0 pCi/L.
Can I get a phone quote instead of a visit? +
We don't provide phone-only quotes for mitigation. A phone estimate can't account for foundation layout, slab elevation changes, or how air moves beneath the home — which is exactly what led other contractors to recommend an unnecessary second system here.
Do you test the system after installation? +
Yes. Every installation includes post-mitigation testing to confirm the level has dropped and the system performs as designed — the step that verified the drop from 5.0 to 0.8 pCi/L on this project.
Is an older home more likely to have elevated radon? +
Home age by itself doesn't determine risk; soil conditions beneath the home matter more. But older homes can have settling, cracks, or foundation modifications that create new entry points, which is one more reason a physical inspection beats an estimate based on square footage.

This is how we approach every job in Spanish Fork — on-site evaluation first, diagnostics before design, and no equipment installed that the testing doesn't support.
