After many years as a licensed contractor doing remodel and refurbishing for my own company, I have decided to move to inspections so I can help homeowners to be aware of issues with their houses and for home buyers to be fully aware of any issues they may have missed in the homes they plan to buy. I take great pride in my professionalism, timeliness, and superior customer service on every job. I make sure to develop a lasting relationship, so that the next time service is needed, there will be no question on who to call.

"Jeff was responsive, easy to work with, and took the time to understand what my concerns were with the property we were considering."

As the owner of Oregon Elite Inspections, I pride myself in being the friendliest inspector you will ever meet! I want you to feel free to contact me after the purchase with any questions you may have about your home. No question is a dumb question! I love teaching people things about their new home that they may not know about. Buying a home could be the largest single investment you will ever make. You want to find your dream home, but you should know that no house is perfect, not even brand new ones. To minimize unpleasant surprises and unexpected difficulties, you'll want to learn as much as you can about the newly constructed or existing house before you buy it. As a trained inspector, I will point out areas of concern during the inspection, such as major repairs that may be needed or builder oversights, as well as the need for maintenance to keep it in good shape. After the inspection, you will know more about the house, which will allow you to make decisions with confidence.

FAQs for radon gas testing projects in Sherwood, OR

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.
