"Did mold remediation in 2020 before house was purchased. Mold found in attic. Resolved it with a 4 year warranty expiring 3-23-24. In January 2024, found mold in same spot. They inspected and sent an estimate to remove. Asked about the warranty still in place. Never responded. Did a good job of remediation work. Doesn’t support their warranty."

"Matt did an excellent job. He came to my house, assessed the basement, offered to arrange for a dumpster, and removed the damaged items left by the previous occupants. He provided two quotes, one including the dumpster fee and one without. A week later, he returned and worked quickly and efficiently. He was polite, professional, and hardworking throughout the process. Thanks to his efforts, my basement no longer has a moldy smell, and there’s no sign of mold, which was our biggest concern with winter approaching. I highly recommend his services."

Lead paint can be found in almost 75% of all housing built before 1978 and a dangerous mold infestation could exist in any home no matter how old the home is. A professional inspection from ASAP Environmental is the best way to protect yourself before you buy.

"We had a pipe break in our kitchen ceiling and an issue with condo owners that felt “the mold was everywhere”. Christopher was amazingly knowledgeable and explained all of the issues without being an alarmist putting us all at ease and did a thorough inspection. As an architect for 40 years he was the best mold expert that I have met and would highly recommend them."

FAQs for radon gas testing projects in Ashland, MA

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.
