Radon Measurement and Mitigation

Gavin Healy of Balance Point Home Performance is a licenced radon menasurement and mitigation provider in the state of California.  In working with our customers to achieve low energy homes with good indoor airquality we have discovered the need to add Radon measurement and mitigation services to our buisness.  While we didn't start our buisness with the goal of working on radon systems, we feel it is important to priortize and mitigate those things in our home that have the greatest potential for causing us harm.  Radon which is a soil gas and is certainly one of those things that can harm us.   The good news is that all homes can be mitigated for Radon.  The bad news is that many homes have elevated radon levels and because there are no immediate symptoms associated with radon many people falsly assume that it is not an issue in thier home or where they live.   We have tested and remdiated homes in Nevada County that have had more than 10 times the EPA recomended threashold for Radon.

How we test for Radon:  

We use a Continous Radon Monitor (CRM) to measure hourly radon levels in accordance with EPA and NRPP stadards.  When we are contracted to work on a home to reduce the levels of Radon we test our work to ensure that we have meet the goal.  Once we have mitigated a home we are confident in the test results.  (it is always recommended that you have a third party test your house so that you don't have to just take our word).  We apply our deep knowldge building science and building performance testing to ensure that the radon system we install work with the other systems in the house.

How we fix Radon:

  • Subslab Depressurization
  • Active and Passive Soil Depressurization
  • Mechancial Ventilation control strategies
  • Planing and Implementing for new construction mitigation systems (with empahsis on low energy consumption)

One size does not fit all.  How much it will cost to mitigate your house depends on the following factors:

  • The target level of radon you want to reduce your house to (typically less than 4PciL though some customers desire lower levels)
  • If you want the radon vent pipes and fan (typically 4inch pipes) surface mounted on the out side of your house, or if you want to concel the pipes up through interior walls for asthetic considerations.
  • How quiet you want your system to be.
  • If your system requires specific planning for freeze protection
  • If you want to design a system that minimizes the electric consumption from the fan
  • Houses with accessible attics and full crawlspaces tend to cost less to mitigate than slab on grade houses and houses with no attic space.
  • How difficult it is to run a dedicated electric circut to wire the radon fan (for some houses a dedicate ciruct is allready available, for others it requires running a new electric wire from the pannel to the fan)
  • The type of roofing material and roof access can impact the cost of the system.  A vent pipe will need to be flashed through the roof, this is typically easy for standard composition roofs, but can be more costly for other types of roofs. 

If you live in Nevada County (we sometimes work in neighboring counties) and you would like for use to design a system and provide a quote give us a call or send us and email and we will schedule an appointment.
