"My condo is dated and lacks proper ventilation- aka no fans in the bathroom. So that combined with living in the pacific northwest is a recipe for disaster and perfect breeding ground for mold to accumulate. After dealing with a smell that would not quit for months I decided it was finally time to have my home inspected and gave Mold Masters a try. As a first time home owner I was unsure what to expect. Mold Masters was professional, honest, and guided me through the whole experience. I would highly recommend this business to anyone looking to improve their home and health."

If you are thinking about a complete lawn renovation or just maintaining your existing landscape we can help. We come up with a design that fits your budget and lifestyle. This includes pavers/hardscapes, water features, complete lawn installation, low-voltage lighting, retaining walls, complete irrigation installation to name just a few of our services in our 'build' division. In maintaining your current landscape, we offer mowing, pruning, irrigation clock re-configuring, and general clean-up. We also offer help with your one-time problems such as drainage issues, broken sprinkler heads, pruning, water leaks in your irrigation system, one-time mow and clean up, or even suggestions for your yard enhancements. If you have a need, we can help.

"I called to request a bid on Monday for routine lawn care with a probability of landscaping later in the year. An appointment for an evaluator was made for the next day. I was impressed with the evaluator and had them in first place based on his presentation. I asked for the bid to be made by Friday (3 days later) and was assured that Fridays were his day of writing and submitting bids. No bid arrived. When I called on Saturday, I got voicemail. Support staff called back on Monday and I was told that a bid would arrive on Friday (11 days after the first call). I stressed that I was eager to make a decision, and that 10 days seemed like a long wait when most providers had bids in 1-3 days after the visit. The support staff said that the following Friday would be the soonest possible. I called Friday morning to verify that a bid was coming that day and was assured that it was. No bid was received by 4 pm, so I called again and got voicemail. I have not heard back from them. I don't know if it is a case of cruelty or incompetence, but it is surely unprofessional to string me along for 12 days when others took 1-3 days. If they decided not to bid, they could have told me rather than "ghosting" me and wasting my time with false promises."

FAQs for radon gas testing projects in Vancouver, WA

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.
