Radon Testing & Mitigation

Protect Your Home & Health with Professional Radon Services

Radon is a colorless, odorless, and tasteless radioactive gas that can seep into your home through cracks in the foundation, basement floors, or even through your water supply. Long-term exposure to high levels of radon is the second leading cause of lung cancer in the United States, making it critical to test and mitigate radon levels in your home. At Dor-Mar Heating, Air Conditioning, Plumbing, and Water Treatment, we offer comprehensive radon testing and remediation services to protect your family from this invisible threat.

What is Radon & Why Is It Dangerous?

Radon is a naturally occurring radioactive gas that forms when uranium in soil, rock, and water breaks down. While it is present in outdoor air in small amounts, it can accumulate to dangerous levels indoors, particularly in basements, crawl spaces, and lower levels of homes.

Health Risks of Radon Exposure:

  • Lung Cancer: Prolonged exposure to high radon levels increases the risk of lung cancer, even for non-smokers.
  • No Immediate Symptoms: Unlike carbon monoxide poisoning, radon exposure has no short-term symptoms, making regular testing essential.
  • Radon in Water: Radon can also enter your home through well water, contributing to both air and drinking water contamination.

Our Radon Services

Radon Detection & Testing

Since radon is invisible and odorless, the only way to determine if your home has elevated radon levels is through professional testing. We offer:

  • Short-Term Radon Testing – Quick assessments to determine radon concentration levels.
  • Long-Term Radon Monitoring – Continuous radon monitoring for more accurate exposure readings.
  • Water Radon Testing – Essential for homes using well water, as radon can dissolve and be released into indoor air when water is used.

Radon Remediation & Mitigation

If your home has elevated radon levels, our experts design custom mitigation systems to reduce radon to safe levels. Our methods include:

  • Sub-Slab Depressurization (SSD): The most effective radon mitigation technique, involving a vent pipe and fan system to draw radon out from beneath your home before it enters living spaces.
  • Crawl Space Sealing & Ventilation: Prevents radon from seeping into homes with exposed dirt crawl spaces.
  • Radon-Reducing Water Treatment Systems: Designed to remove radon before it enters your drinking water, ensuring clean, safe water.

How Does Radon Enter Your Home?

Radon gas moves from the ground into your home through:

  • Cracks in foundation walls and floors
  • Gaps around pipes and drains
  • Crawl spaces with exposed soil
  • Sump pumps and basement drains
  • Private well water sources

Once inside, radon becomes trapped, leading to dangerous indoor air levels. Without mitigation, radon continues to accumulate, posing a growing health risk.

The Importance of Radon Testing

When Should You Test for Radon?

  • Buying or Selling a Home: Radon testing is highly recommended during real estate transactions.
  • After Home Renovations: Structural changes can alter radon levels, requiring retesting.
  • If You Use Well Water: Radon can enter homes through groundwater, requiring specialized testing.
  • Every Two Years: Even if previous tests showed low levels, radon levels can change due to shifts in soil, weather conditions, and new home construction nearby.

Radon in Water: Is Your Drinking Water Safe?

Many homeowners are unaware that radon can enter homes not just through the air, but also through private well water supplies. When radon-laden water is used for showering, cooking, and drinking, radon gas is released into the air, increasing exposure risks.

We provide specialized water treatment systems to remove radon from well water before it reaches your tap.

Frequently Asked Questions About Radon Services

How do I know if my home has high radon levels?

The only way to know is to perform a radon test. Radon is an invisible, odorless gas, so it cannot be detected without specialized equipment.

Is radon only a problem in basements?

No. While radon is more common in basements and crawl spaces, it can spread throughout the entire home, including upper floors.

What is considered a dangerous level of radon?

The EPA recommends action if radon levels exceed 4.0 pCi/L (picocuries per liter), though even lower levels pose health risks over long-term exposure.

How long does radon testing take?

Short-term tests take 2-7 days, while long-term tests can take 90 days or more for more accurate readings.

Can radon be completely eliminated?

No, but mitigation systems can reduce radon levels by up to 99%, making your home safer for long-term living.

Will a radon mitigation system increase my energy bills?

Radon mitigation systems use minimal electricity, typically costing less than $5 per month to operate.

Does radon mitigation require major home renovations?

No. Most mitigation systems are installed quickly with minimal disruption, often requiring only a small vent pipe and fan system.

Darren HallDarren Hall ★★★★★ Response from the ownerThank you for the 5-star rating Darren! Terri GuoTerri Guo ★☆☆☆☆ We paid the yearly maintenance fees, they didn’t do the maintenance at all only charged for the money, the maintenance guy said my furnace need to put a UV light to kills the moisture, when he came he told me our water heater need to be replaced and he said if we buy the water heater from them he’ll install the UV LIGHT for free at least 50% off, and clean it for free. After we replaced the water heater they didn’t do it, we still paid a lot money for the UV LIGHT and they didn’t clean it at all so DisappointedResponse from the ownerWe appologize that you have had your maintenace reasxheduled a couple of times Terri, unfortunely with the heat wave we expirienced all working units had to be moved off of the schedule to take care of people without working ACs. As far as the UV light our record indicates extensive notes on where we installed a UV light at one of your properties and that you canceled the one for your home address. If you wish to further discuss your issues you may reach out to our office. Dorothy McCulloughDorothy McCullough ★★★★★ Trevor did an awesome job. He was so professional and nice.Response from the ownerThank you for leaving your tech a great review! js_loader
