Residential Radon Testing LLC

Radon Testing. Most homes have radon. How much is in yours?

For Selling Agents

We save you time. We have SentriLock access so you do not have to meet us at the property. We will arrange entry into the home with the listing agent. You will be copied on all email communications and confirmations. Protect your buyers by including a radon testing contingency in your contracts. Testing can be performed 2 days before the home inspection to have results at the same time the home inspection is completed. 

We Can Make All The Arrangements

The Listing Agent is contacted, informing them of the impending radon test dates and times for both placement and retrieval. Selling agents are cc’d on all communications. 

  

We are an affiliate member of the REALTOR® Association of Prince William (PWAR) and have SentriLock access so you, the selling agent, do not have to meet us at the property to either place or retrieve the testing devices.  Access to a property is granted by the Listing Agent by providing us the CBS code (Call Before Showing) to the SentriLock  installed at the property. See instructions below on how to find your CBS code.


Your clients are invoiced by email where they can pay online using a credit card or a PayPal account.
