Fullerbuilt Radon Mitigation Llc | Radon Mitigation in Larkspur, CO

What We Do

Complete radon solutions for your peace of mind

From the first test to the final system check, we guide you through every step. No jargon, no pressure — just clear answers and a home that's safe for your family.

Radon Testing

Accurate, certified radon testing using professional-grade detectors. We offer both short-term and long-term testing to give you a clear picture of your home's radon levels.

Mitigation Systems

Sub-slab depressurization and other proven mitigation systems designed to pull radon gas from beneath your home and vent it safely outside — keeping indoor levels well below the EPA action threshold.

Re-Testing & Verification

After a mitigation system is installed, we perform post-mitigation testing to confirm your home meets safety standards. We also offer re-testing for homes being bought or sold.

Mobile Home Mitigation

Mobile and manufactured homes have unique radon challenges. We specialize in custom solutions designed specifically for these structures, ensuring thorough protection without compromising the home.

System Monitoring

Stay informed with radon system monitoring services. We help you understand your system's performance and set up alarms so you're always aware if anything changes.

Consultation & Education

Not sure what radon is or whether your home needs mitigation? We provide honest, no-obligation consultations to help you understand the risks and your options — clearly and without fear.

The Hidden Risk

Radon is invisible, odorless, and Colorado's #1 environmental health threat

Radon gas seeps up from the ground and can accumulate to dangerous levels in any home — regardless of age, foundation type, or location. The EPA estimates radon causes over 21,000 lung cancer deaths every year in the United States. Colorado has the highest radon levels in the nation.

You can't detect it yourself

Radon is completely undetectable without professional testing. The only way to know your risk is to test.

Mitigation is straightforward and effective

A properly installed radon reduction system can lower radon levels by 99% or more — and it's a one-time fix that works for decades.

Your family's health is worth the investment

Radon exposure is the second leading cause of lung cancer. Protecting your home is one of the most important things you can do for your family's long-term health.

How It Works

From test to safe home in three simple steps

We keep things straightforward. No surprises, no hidden fees — just clear communication and a job done right the first time.
