How do I know if I need radon mitigation in Lafayette, CO?

If your test came back at 4 pCi/L or higher, you need a system. That is the EPA action level and it is the number that matters. Under 4, you probably do not need one right now. If your result is borderline, like 3.8, it is worth testing again before spending money. If it is 6 or 8, that is not a close call.

Will the system tear up my finished basement?

No. We build a soffit or a false wall so the pipe disappears into the room. If there is no outlet near where the fan goes, we wire one in. We do that framing and finish work ourselves instead of hiring it out, so you are not waiting on a second contractor.

Is the pipe going to be ugly on the front of my house?

Not if we can help it. We run the outside vent through a downspout instead of leaving bare white PVC bolted up the wall. It costs us a little more time and it makes the system look like it belongs there.

What does a radon system cost?

It depends on your foundation, and anyone quoting you over the phone is guessing. An open slab is the simplest job we do. A finished basement adds framing and finish work. A crawl space adds a vapor barrier sealed at every seam. We walk the property, plan the system, and give you one price before we start.

Do you offer financing?

Yes, through Affirm, Afterpay and Klarna, so you can spread the cost out instead of paying it all at once. Most people are not budgeting for a radon system when their test comes back high. We go over the options during your free visit.

How fast can you get a system in before my closing?

Call us as soon as you know mitigation is a condition. We keep materials stocked, so the install often follows right after the visit. Tell us your closing date when you call and we will tell you straight whether we can make it.

Why Homes in Lafayette Need Radon Mitigation

Radon is a gas that comes up out of the ground. A high level does not go away on its own, and a system is what brings it down.

It moves through cracks in the slab, an open sump pit, or bare dirt in a crawl space, and it collects in the lower level of the house. Sealing cracks alone does not stop it.

Radon mitigation does. The system pulls air out from under the slab so the radon stays in the ground instead of coming up into the house. Once the fan is running, it runs.

It also settles the question for a buyer. In Colorado, sellers have to disclose what they know about radon, and a system in place is the answer a buyer is looking for. Same for a new build that needs one to pass inspection.

We will look at your test result with you and tell you straight whether radon mitigation makes sense for your foundation. If it does not, we will say so.

We come out, plan the system, and give you one price. Free.

Radon Mitigation Services in Lafayette, CO

Different foundations need different systems. Here is the radon mitigation your house most likely needs.

Crawl Space Radon Mitigation

For houses sitting over a dirt crawl space. We lay a heavy vapor barrier across the whole floor and seal it to the walls and piers, then run the system through the barrier itself.
Crawl space systems
Radon Fan Replacement

You already have a system and the numbers are climbing again. A worn out or failed fan is usually why. We swap it and get the system pulling the way it should.

Most common
Sub-Slab Radon Mitigation

The standard install for a slab or basement. We core drill one hole, seal it, run pipe up to a fan, and vent it out above the roofline.

How Radon Mitigation Works in Lafayette

One Price Up Front You get one number before we start. No add-ons on an invoice later.
We Install It Core drill, seal, run the pipe, mount the fan, vent above the roofline.

If a closing depends on the system, tell us when you call. Radon comes up during the inspection period on a lot of Boulder County sales and the timeline is usually tight. Give us your closing date and we will work around it.

What Happens on Install Day

Every job starts the same way. We core drill one hole through the slab, usually in a low-traffic spot like a utility room corner. That hole is the suction point. We seal around it, run pipe up through the house, connect it to a fan, and vent it above the roofline.

The fan does not pull radon out of your house. It pulls air out from under the slab, dropping the pressure below the floor. Radon stays in the ground because nothing is pulling it up anymore. The whole system works underground, before radon ever gets inside.

From there it depends on your foundation

Open slab or unfinished basement Pipe runs straight up through a corner or the rim joist. The fan mounts in the attic or on the outside wall.
Finished basement We build a soffit or a false wall so the pipe disappears into the room. No outlet for the fan? We wire one in.
Dirt crawl space A heavy vapor barrier sealed across the floor and to the walls, with the suction point run through the barrier.

We hide the outside pipe. The vent runs through a downspout instead of bare white PVC up the front of the house. It makes the system look planned instead of tacked on.

Locally Owned Radon Mitigation in Lafayette

Ty Silver and his father run this business together. Both of them answer their own phones, and one of them is the person who shows up at your house. You are not handed off to a salesman and then a crew you have never spoken to.

They also do the construction side themselves. Framing a soffit, cutting in an outlet, closing the wall back up. Most radon companies farm that out or turn the job down.

Those are different jobs with different numbers. Anyone quoting you over the phone is guessing. We walk the property first, then give you one price before we touch a drill.

Why Radon Runs High in Boulder County Homes

The soil along the Front Range has more uranium in it than most of the country. It is not about how old your house is. It is about what is under it.

Radon comes from uranium in soil and rock breaking down. Colorado sits on soil with more of it than most of the country, and Boulder County is no exception. That is why so many homes here test above the EPA action level of 4 pCi/L.

The age of the house has little to do with it. Two houses built the same year, right next to each other, can test completely differently depending on how the soil settled or how the foundation was poured.

A lot of the older neighborhoods around Lafayette went up before anyone was thinking about radon, so basements finished over the years usually have nothing under the slab. Winter runs higher too. Your furnace pulls air out of the house, which pulls more radon up through the floor. That is why most radon mitigation calls in Lafayette come in during the cold months.
