Sub-Membrane Depressurization (SMD)

This high-end home required a customized radon mitigation system following elevated results from a professional radon inspection and radon test. After confirming unsafe indoor radon levels in the crawlspace, our team designed and installed a Sub-Membrane Depressurization (SMD) system, one of the most effective radon mitigation methods for crawlspace foundations. The system included a durable vapor barrier membrane sealed across the crawlspace floor, strategically placed suction points, and a high-performance radon fan to safely redirect radon gas away from the home. To preserve the architectural integrity of the property, we carefully routed the exterior discharge piping to blend seamlessly with the home’s upscale exterior design. This installation not only reduced radon levels to meet EPA-recommended standards but also ensured long-term indoor air quality protection for the homeowners in Durango, CO.

Frequently Asked Questions

Are new homes safe from radon?

No. In fact, newer homes can sometimes have higher radon levels because modern construction is more airtight. Radon comes from the soil beneath your home — not from the age of the house.

Does a radon system increase home value?

Yes. A mitigation system is often seen as a proactive improvement and can simplify future real estate transactions by eliminating radon concerns during inspections.

How do I know if my home has radon?

Radon is invisible and odorless — there’s no way to detect it without testing. Even homes next door to each other can have completely different radon levels. The only way to know is to test.

How long does a radon test take?

Most professional tests run for 48 hours to ensure accurate results. After testing, we review the findings with you and explain exactly what they mean for your home.

How long does installation take?

Most mitigation systems are installed in a single day. You can remain in your home during installation.

Is radon mitigation loud or noticeable?

No. Modern mitigation systems are quiet and discreet. The vent stack is typically placed along the exterior of the home, and the fan operates with minimal noise.

Is radon really that dangerous?

Radon is the second leading cause of lung cancer in the United States and the #1 cause among non-smokers. Long-term exposure increases risk — which is why early detection matters.

What does a radon mitigation system cost?

Costs vary depending on your home’s layout and foundation type. After testing and evaluation, we provide transparent pricing before any work begins.

What happens if my levels are high?

If radon levels exceed EPA recommendations (4.0 pCi/L), we design a mitigation system tailored to your home’s structure. Most systems reduce radon levels by up to 99%.
