Interior & Exterior Vent Routing for Radon Systems

One of the most important parts of a radon mitigation system is the path the vent pipe takes. Vent routing is what carries radon gas from beneath your home and safely releases it above the roofline. At BreatheWell Radon Solutions, we design and install both interior and exterior venting routes, making sure your system works efficiently while also fitting the style of your home.

Why Proper Vent Routing Is Important

A mitigation fan can’t do its job unless the vent pipe is placed correctly. The vent line is like the exhaust system for radon gas—it directs the flow up and away from your living spaces.

If venting is poorly planned, it can reduce performance or even let radon drift back into your home. Placement also affects how the system looks on your property. That’s why we follow EPA and state safety standards closely and give every installation the attention it deserves.

Interior Vent Routing

Interior vent routing means the pipe runs inside your home, often tucked behind walls, through utility areas, or up to the attic before exiting the roof.

Many homeowners prefer this style because:

• It’s hidden from view – No pipes running up the exterior of your house.
  
  
• Added durability – Protected from harsh weather and sunlight.
  
  
• Quieter system – Fans are often located in attics, reducing noise indoors.
  
  

Interior venting requires careful planning, but our team is skilled at finding routes that protect both performance and your home’s appearance.

Exterior Vent Routing

Exterior vent routing places the pipe on the outside of your house, running upward until it vents safely above the roofline. This setup is popular because:

• It’s more affordable – Usually less labor-intensive than interior routing.
  
  
• Simple maintenance – The fan and pipe can be accessed without entering the home.
  
  
• Works for tricky layouts – Ideal when interior paths aren’t possible.
  
  

When we install exterior piping, we do so with care—choosing locations and materials that are reliable, code-compliant, and visually unobtrusive.

Our Step-by-Step Approach

Every mitigation system we install is tailored to the home. Here’s how we make sure vent routing is done right:

1. Evaluate your home – We check the basement, foundation, attic, and exterior for the best pathways.
   
   
2. Present your options – You’ll know the pros and cons of interior vs. exterior venting.
   
   
3. Design for compliance – We follow EPA standards for height and distance so radon is released safely.
   
   
4. Install with care – Pipes are sealed, joints tested, and fans properly placed for long-term performance.
   
   

The result is a system that lowers radon levels below the EPA’s action level and runs dependably without disrupting your home’s look.

Lasting Safety and Confidence

Vent routing is not just about installation—it’s about protecting your family’s air for years to come. A well-designed system runs quietly, efficiently, and without worry.
