Water Line Repiping
If you own a home in Longmont, there’s an invisible risk you can’t afford to ignore: radon gas. It has no smell, no color, and no taste, yet it’s the second leading cause of lung cancer in the United States, according to the EPA. And because much of Colorado sits in a high-radon zone, testing here isn’t optional peace of mind. It’s smart homeownership.
That’s where professional radon mitigation in Longmont, CO comes in. At EP Plumbing, Heating & Air, we help families along the Front Range measure radon levels, design effective mitigation systems, and breathe easier in their own homes. Whether you’re buying, selling, finishing a basement, or just being proactive, we’re the local team you can trust to protect your indoor air quality.
Our Radon Mitigation Services in Longmont

Radon is a naturally occurring radioactive gas. It forms as uranium in soil and rock breaks down, then seeps up through foundation cracks, floor joints, sump pits, and crawl spaces. Once inside, it can build up to unsafe levels, especially in basements and lower floors where air is close to the ground.
The EPA measures radon in picocuries per liter (pCi/L) and recommends taking action at levels of 4.0 pCi/L or higher. But because there’s no truly “safe” level of radon gas, many homeowners choose to reduce it even further. The only way to know your home’s level is to test, you can’t see, smell, or taste radon, and elevated exposure produces no immediate symptom

Sub-Slab Depressurization Systems

When every drain in the house slows down at once, or you notice gurgling and drain odors, the problem is usually in the main line. Main drain line cleaning often means clearing tree roots, grease, or a blocked cleanout before the whole system backs up.
Our rooter service uses powerful machines to cut through roots and break up heavy blockages deep in the sewer line. For homes on Longmont’s older tree-lined streets, root intrusion is one of the most common reasons a main line fails, and a rooter is often the fastest fix.
