What is radon?

A naturally occurring radioactive gas that seeps up from the ground and into buildings. It’s invisible, odorless, and tasteless, so a test is the only way to know your level.

Radon forms when uranium in soil and rock breaks down. As the gas rises, a house acts like a chimney: warm air leaving through the upper floors pulls soil gas in through the foundation. Levels are often highest in basements and lower floors, and they change with weather and season.

Breathing radon over years exposes lung tissue to radiation. The U.S. EPA and Surgeon General recommend testing every home, and fixing it when results reach 4 pCi/L or higher. Any house can have high radon — new or old, with or without a basement — and two neighboring homes can test very differently.

  • Floor–wall jointsThe seam where the slab meets the foundation
  • CrawlspacesExposed dirt floors under living space
  • Pipe gapsOpenings around plumbing and utility lines
  • Well waterRadon can release from water into the air

What we do

Two jobs, done carefully: find out how much radon you have, and bring it down.

Testing

Calibrated continuous monitors placed in the lowest lived-in level of your home.

Short-term test (48 hours)
A fast snapshot of your radon level with an hour-by-hour report.
Real estate test
Tamper-resistant monitor and a report ready for buyers, sellers, and agents.
Commercial & rental
Multi-unit and workplace testing on a schedule that suits tenants.

Mitigation

Systems designed for your foundation, installed neatly, and verified by retest.

Sub-slab depressurization
A suction pipe under the slab and an inline fan vent radon above the roof.
Crawlspace encapsulation
Sealed vapor barrier over the dirt floor with suction beneath it.
Sump & crack sealing
Airtight sump covers and sealed slab cracks to strengthen the system.
System service
Fan replacement, repairs, and checkups on existing systems.

How it works

  1. Test

    We place a monitor and pick it up after 48 hours.

  2. Review

    We walk you through the results and quote a system if you need one.

  3. Install

    Most mitigation systems go in within a single day.

  4. Verify

    We retest to confirm your levels dropped below the action level.

Recent installs

Clean pipe runs, sealed penetrations, and a pressure gauge on every system so you can see it working.

Book an appointment

Pick a day and time window. We’ll review your request and confirm by phone or email, usually within one business day.

  • Testing visits take about 20 minutes
  • Mitigation starts with a free on-site estimate
  • Saturday appointments available

    Common questions

    How long does a radon test take?

    A standard short-term test runs at least 48 hours. Keep windows and outside doors closed during the test, except for normal coming and going.

    My neighbor tested low. Do I still need to test?

    Yes. Soil, foundation type, and construction vary from house to house, so neighboring homes can have very different levels.

    How much does a mitigation system lower radon?

    A well-designed sub-slab system commonly reduces levels by 80 to 99 percent. We retest after every install to confirm the result.

    Will the fan be loud or expensive to run?

    Radon fans are mounted outside the living space, usually on an exterior wall or in the attic, and run quietly on about as much power as a light bulb.

    Do you test homes being bought or sold?

    We do. Real estate tests use tamper-resistant monitors and we can schedule around inspection deadlines.
