On First Contact

EXPECT professionalism -- always

The Testing Report

You should receive a PROFESSIONAL Report of Testing after the laboratory analysis comes back.  The report you are given should be well organized, well written, use a limited amount of jargon and acronyms, and contain at least the following:

     -     Cover Page
          *   Name and Signature of individual issuing report on cover
          *   Names of any other individuals

     -     Letter of transmittal
          *   Letter should summarize dates of testing & results
          *   Letter should make recommendation for mitigaton or not and why
     -     Table of Contents
     -     Geologic Setting
     -     Property Description
     -     Testing Information
          *   Dates of Test
          *   Type of Testing Media
          *   Name, phone number, and address of Laboratory
      -     Results of Test
      -     Evaluation of Radon Hazard
      -     Recommendation for Mitigation (or not) and why
      -     If Mitigation is recommended
          *   Which type of mitigation
          *   Complete proposal including all costs for installation of mitigation
      -     Drawings of area of testing showing placement of canisters
      -     Scaled or dimensioned site plan


Ask for a sample copy of our standard multi-page ASTM/EPA approved format Report!


The Mitigation should take no more than 2 days to install and get up and running.  Your mitigator should:

     -     Arrive on time
     -     Have all tools and supplies required
     -     Provide you with identification and a drawn plan for installation
     -     Lay down drop cloths to protect the work area inside and out
     -     Proceed to install the mitigation system without interruption
     -     The installed mitigation system should be weather tight from inside to outside
          *   direction arrows shall be displayed on mitigation piping to indicate air flow direction
          *   a manometer shall be installed below the in-line blower and inside the dwelling to indicate system performance
          *   a label shall be placed on the electrical breaker providing power to the blower
          *   a clear plastic protector shall be placed over a legible performance scale to indicate proper operation of the mitigation by reading the manometer
          *   Blower shall be mounted on the OUTSIDE of the dwelling unit when possible but may be mounted inside when required by local conditions
          *   The exit stack shall rise ABOVE the roofline and not be tucked under the roof eave
     -     Installation report shall be delivered to owner



Mixed materials in piping are not desireable and not optimal and show a certain degree of cheap shortcutting.  Get what you pay for!

Post Installation Service

The job is not over yet!


After several days of operating  your mitigator should come back to inspect the installation for proper operation and make any adjustments necessary for free.  You should receive your post installation report at this time.


After the mitigator has assured proper operation of your system, he/she should place a single testing canister for a short-duration 3-day test in a manner previously described.


Your report should contain a diagram drawing of the type of installation placed in/on your home and a statement that regular (at least annual) testing should be performed in the mitigated space to insure effective operation of your system and safety. 

You should inspect the system manometer at least monthly to make certain it is operating optimally.
