Sub-Slab Depressurization

The Most Reliable Way to Reduce Radon in Homes


One of the most trusted methods for lowering radon levels in houses is sub-slab depressurization, often referred to as SSD. This system is the EPA’s top recommendation for homes with basements or concrete slab foundations.


At BreatheWell Radon Solutions, we install these systems with precision so families can feel confident their home is safe from harmful radon gas.

Why Hire a Professional Installer


Installing a radon system isn’t a DIY job. The design and details matter if you want results you can trust.


When you hire BreatheWell, you get:

  • Custom Planning – We tailor each system to your home’s layout and radon levels.

  • Trained Experts – Our team follows EPA protocols and local codes.

  • Durable Equipment – We use high-quality fans and materials for long-lasting performance.

  • Verification – Every job ends with testing to confirm radon is under control.


This process keeps radon out of your breathing air and pushes it safely outdoors.

Radon seeps up from the soil through small cracks, gaps, and openings in your foundation. Sub-slab depressurization stops this at the source.


Here’s the basic idea:

  • A small hole is drilled through the basement floor to create a suction pit.

  • A pipe is attached and runs to a specially designed radon fan.

  • That fan continuously pulls radon from beneath the slab and vents it well above the roofline.

This process keeps radon out of your breathing air and pushes it safely outdoors.

Why Choose This Approach


Because radon comes directly from the ground, pulling it out before it enters your house is the most effective strategy. Sub-slab depressurization has clear advantages:


  • Proven effectiveness: It consistently reduces radon to safer levels.

  • Continuous protection: The system runs all the time without you needing to think about it.

  • Energy-efficient and quiet: Fans use little electricity and operate quietly in the background.

What to Expect During Installation


Every home is different, so each system is custom-designed. Here’s our typical process:


  1. Foundation check: We inspect your basement or slab to decide the best system design.

  2. System planning: We choose the most effective location for the suction point, piping, and fan.

  3. Installation: Our trained team installs the system neatly and with attention to detail.

  4. Testing: After installation, we verify radon levels have dropped.

  5. Support: We provide future fan replacement and system guidance whenever you need it.

Sub-Slab Depressurization FAQ

  • How much does a radon mitigation system cost?

    It tackles radon at the source. By pulling gas from under the concrete slab and venting it outside, it prevents radon from entering your home in the first place.


  • Can every home use this system?

    Most homes with a basement or slab foundation can. Our team evaluates each property to design a system that works for its unique layout.


  • Will it change the look of my house?

    Not much at all. The piping is installed neatly inside and vented outside where it’s least noticeable. We design with both performance and appearance in mind.


  • How long does installation usually take?

    Typically, a single day. Once complete, we test to confirm your radon levels have been reduced.


  • Does the system need upkeep?

    The only maintenance is fan replacement about every 7–10 years. Otherwise, the system runs automatically without much attention.
