"Rob's remediation plan was clear and dealt with two crawl spaces simultaneously with one fan. The other contractor's we got estimates from were looking at two systems. His laborers were friendly and competent. They also cleaned up after themselves at the end of the first day even though they were coming to finish the job the next day. Nice clean up at the end of the job."

Additional DBA - Renewal by Andersen, an Andersen Company.

"We bought an older home and several windows were letting in the winter draft. We decided this past year to have the windows replaced. From the consultation appointment to installation this company was completely professional. We did not feel forced into buying and the installers did an exceptional job. Our house stayed much warmer this winter. We will be using Renewal again!"

FAQs for radon gas testing projects in Grand Junction, CO

Radon fans last between five and 10 years with continuous operation. Many manufacturers provide warranties ranging from one to five years. Rather than replacing on a fixed schedule, monitor your system for signs of failure such as unusual noises, vibrations, or changes in system pressure readings. Regular inspections can help identify when replacement is necessary before radon levels increase in your home.

While experienced homeowners with knowledge of radon systems might replace their own fans, most should hire professionals. The process involves electrical work and precise sealing to maintain system effectiveness. 

Improper installation could lead to radon exposure or system inefficiency. Since professional replacement costs are reasonable, most homeowners choose certified radon specialists to ensure proper installation and system function.

Watch for warning signs such as unusual or excessive noise from the fan, vibrations, or changes in your system's manometer or pressure gauge readings. If you notice rising radon levels during routine testing, this could indicate fan failure. Physical damage to the fan housing or water leaks around the unit also suggest replacement is needed. Regular system inspections can help catch these issues early.

Contact certified radon mitigation specialists or professionals with specific experience in radon systems. These experts understand the importance of proper fan sizing and installation techniques. They can ensure your system maintains effective radon reduction and complies with safety standards. Working with qualified professionals provides assurance that your home remains protected from harmful radon gas.

Standard homeowners' insurance policies usually don't cover radon fan replacement, as this is considered routine maintenance rather than sudden or accidental damage. Some home warranty programs might include radon equipment coverage, so check your specific policy details. In most cases, radon fan replacement is a homeowner's responsibility as part of normal system upkeep.
