Start with an actual test
EPA recommends testing homes for radon. A neighbor’s result, a home’s appearance, or a regional risk map cannot tell you the result in your own home. Keep any prior test records and follow the current instructions for the test method being used.
Tell the professional what will change
Share the renovation plans with the person assessing radon. Explain any changes to occupied space, foundations, heating and cooling, or the building enclosure. This gives the professional context for advising on testing and any mitigation needs; a remodel does not by itself establish that a radon problem exists.
Coordinate routes before finishes
If mitigation is needed, discuss routing and equipment locations before new walls or ceilings close. Coordinate with the project’s mechanical, electrical, and other work so one system does not obstruct another. The qualified radon professional should determine the approach rather than having the remodeling crew improvise it.
Protect an existing system
Identify existing mitigation equipment and components on the plans. Discuss any proposed relocation or changes with the appropriate professional. Ask which checks or follow-up testing are needed after the renovation, and keep the instructions and records with the home’s other project documents.
Keep the responsibilities clear
Summit’s role is to coordinate construction. Testing, interpretation, and mitigation should be assigned to appropriately qualified professionals. Include those services in the scope or list them as owner-arranged items so they do not disappear between the design and construction stages.
