Why Chose Smart Space?

At Smart Space, we have over 11 years of experience designing and installing active soil depressurization radon mitigation systems.

Our team is NRPP-certified and installs systems in accordance with current national radon mitigation standards and best practices. During installation, we perform diagnostic pressure testing to verify pressure field extension and to properly size and select the radon fan based on system resistance and performance requirements.

We use only high-quality, long-life system components and materials engineered for durability, reliability, and sustained radon reduction.

Ongoing Testing & Verification

Every installation includes post-mitigation radon testing and reporting, ensuring results meet or exceed EPA action levels.

Why Radon Mitigation Matters in Multifamily Buildings

Radon is a naturally occurring, odorless gas and the second leading cause of lung cancer in the United States. Because multifamily properties often share foundations, ventilation pathways, and utility chases, radon can accumulate at dangerous levels in multiple units—even on upper floors. Properly engineered mitigation is not only a health safeguard but also a legal and financial protection for property stakeholders.

Radon Mitigation Frequently Asked Questions (FAQ)

What is radon and why is it dangerous?
Radon is a naturally occurring radioactive gas formed when uranium breaks down in soil, rock, and water. It seeps into homes through cracks and gaps in foundations and slabs. Because it’s colorless, odorless, and tasteless, it often goes undetected. Long-term exposure increases the risk of lung cancer — in fact, the EPA and CDC identify radon as the second leading cause of lung cancer in the United States after smoking.
How does radon get into my building units/spaces?

Radon enters buildings through openings in contact with the ground, such as:

  • Cracks in concrete slabs and basement floors
  • Gaps around pipes, drains, and sump pumps
  • Crawl spaces with exposed soil
  • Construction joints and wall-floor seams
  • Once inside, radon can build up to unsafe levels—especially in well-insulated, energy-efficient homes that don’t have much air exchange.
How do I know if my building units/spaces has radon?

The only way to know is to test. Radon cannot be detected by smell or sight. Smart Space offers both short-term and continuous digital radon testing, providing a certified report showing your home’s average radon level in picocuries per liter (pCi/L).

  • EPA Action Level: 4.0 pCi/L or higher requires mitigation.

  • World Health Organization Recommended Level: 2.7 pCi/L or higher.

What is a radon mitigation system?

A radon mitigation system is a ventilation and depressurization system designed to draw radon gas from beneath your building and safely vent it outdoors before it enters your living space. Most systems include:

  • A PVC suction pipe installed through the foundation or slab
  • A radon fan that runs continuously to pull gases from beneath the home
  • An exterior vent pipe terminating above the roofline
  • A U-tube manometer (pressure gauge) that shows the fan is operating properly
How long does installation take?

A standard radon system usually takes 1-2 day to install per unit. Multifamily buildings (such as those with multiple foundations, crawl spaces, or basements) may require a second suction point or a custom configuration.

A building with a crawl space can take 3-5 days to complete depending on the size of the crawl space.

Does mitigation really work?

Yes. A properly designed and installed system can reduce indoor radon levels by up to 99%. Smart Space uses NRPP-certified techniques and equipment that meet or exceed EPA Radon Mitigation Standards (RMS) to ensure lasting results and compliance with Georgia regulations.

Will a radon system affect my building's appearance or resale value?

No — most systems are discreetly installed with clean PVC runs and exterior fans mounted on the exterior side (near AC etc) or attic. In fact, radon mitigation system can increase tenants confidence.

Do I need to maintain the system?

Maintenance is minimal:

  • Check the U-tube manometer regularly to confirm suction.
  • Ensure the fan is running and vent outlet remains clear.
  • Retest your home every two years or after major renovations.
  • Fans typically last 8-10 years and can be replaced easily.
  • We offer maintenance plans.
Who regulates radon mitigation?

In the U.S., the EPA, CDC, and state health departments (such as the Georgia Department of Public Health) oversee standards and licensing. Smart Space Atlanta’s technicians are NRPP-certified, ensuring compliance with national protocols.
