Radon mitigation

A radon mitigation system is a permanent, quiet, mechanical solution: a fan pulls soil gas from beneath your home and vents it safely above the roofline, so it never collects inside.

How a system works

Almost every home we treat uses the same principle. A small hole is sealed into the soil beneath the foundation, a pipe connects that point to a fan, and the fan keeps a slight vacuum under the slab. Soil gas that would have seeped into the basement or living space is drawn out and discharged above the roof, where it dilutes outdoors.

From the outside you see one clean pipe run and a fan. From the inside you usually see nothing at all — we route the pipe through closets, garages, or unfinished space to keep finished rooms untouched.

What every installation includes

  • A written, fixed-price quote before any work begins
  • Permit pulled and inspection coordinated
  • Sealed suction point, fire-rated pipe, and a properly sized fan
  • Sealing of sumps, drains, and visible slab cracks
  • Routing chosen to protect finished living space
  • Post-installation radon test to confirm the result
  • Cleanup and haul-away — we leave the house as we found it

Systems we install

Every foundation type needs a different approach. We build the right one for your house, not the one that is easiest for us.

Sub-slab depressurization

The standard for homes with a poured slab or basement floor. One or more suction points under the slab, sealed and vented above the roofline.

Crawl space systems

A sealed membrane over the soil with suction beneath it. Also reduces moisture and soil-gas odors in the crawl.

Block-wall suction

For homes built with hollow masonry foundation walls, where the wall cavities themselves collect and hold gas.

Drain tile & sump points

We tie into existing drain tile and seal sump baskets so the system pulls from the whole footing drain, not one spot.

Multi-point systems

Large or irregular footprints, additions, and split-level homes often need more than one suction point to hold a uniform vacuum.

System service & repair

Fan replacement, re-sealing, testing, and re-commissioning of a system someone else installed.

Real estate transactions

Buying or selling in the metro means tight deadlines. We test, quote, install, and retest on a schedule that fits the closing date, and we send the paperwork where your agent and inspector need it.

If a test comes back elevated days before closing, call us. We have built a sizeable share of our business on closing-week installations.

What we need from you

Access
About a day in the home, plus access to the garage or utility space.
Test results
An existing test, or we run one first.

Helpful, not required — we will confirm on a site visit.
Decision
One fixed price, in writing, before we schedule.

Mitigation questions

Do I need a permit?

Most Colorado jurisdictions require a radon mitigation permit, and requirements vary by city. We pull it and coordinate the inspection as part of the job.

Can you route the pipe where I want it?

Usually, and we will tell you honestly when a route will not work. We plan the run with you before we cut anything.

What if my level is only slightly above 4 pCi/L?

The EPA action level is 4 pCi/L and there is no known safe exposure. Most homeowners at that level choose to mitigate; we will give you the facts and let you decide.
