"AdvantaClean installed a radon mitigation system at my house. Within two years, the piping they put in on the outside of the house to vent the gas collapsed. Upon further inspection, the ~30ft., ~50lb. pipe had been affixed upright by two plastic ties screwed to the siding, and the weight of the pipe had caused the screws to tear through the thin plastic on both ties. Similar systems I've looked at in the neighborhood use lighter, metal, gutter-like pipes, and metal ties (stronger ties for lighter pipes!). When contacted, Dave (the owner) tried to get me to pay $300 to fix it, claiming that he otherwise "couldn't help me" because I couldn't reasonably expect their work to last for almost two years. He also said any kind of warranty was void because "wind damage" wasn't covered. The winds in Frederick topped out at 8mph the day it fell, but I guess he's right. It honestly WOULD be unreasonable to expect this quality of work to hold up to normal weather events (normal storms and winds in a fairly mild weather part of the country) and wear for two whole years! I'm frankly surprised it didn't fall earlier. Oh, and it took me calling AdvantaClean three times to get ahold of him (thought I was promised a call back each time!), but that's way less egregious than the whole "doing sub-par work and trying to get me to pay for it when it failed" thing."

If you are concerned about the possibility you have mold in your home or see evidence of mold growth, contact us immediately! We have experienced Certified Mold Inspectors (CMI #81281) who will come in and do a complete inspection of your home or business. We are positioned to provide an assessment of the indoor air quality or environmental quality concern of private homes, commercial buildings and institutional complexes. If necessary, we will take air samples in the area of concern to determine the levels of contamination. If visible mold is present, we can do surface testing to determine the species of mold. Testing samples are sent to a non-affiliated leading environmental testing firm and test results are back after 48 hours.* After a review of laboratory results from samples taken while onsite and from our visual inspection, we can recommend and refer you to proper mold remediation companies that can correct the issue if deemed necessary. Your safety is our main concern and to the best of our ability, we will be there to help you have “The Safest Air You Can Breathe!” Your peace of mind is our best reward.

Mold Testing and Remediation questions, answered by experts

Water damage always poses the risk of mold, but if you act quickly enough (within the first 24 hours), you may be able to avoid mold growth resulting from water damage. Clean up the water quickly and thoroughly dry the area. If the issue is more extensive or you didn’t act quickly enough, it’s always safer to assume mold has grown and hire a mold inspector to examine the area.

Humidity, moisture, and a lack of ventilation can all cause mold to grow on surfaces in and around your home.

It‘s risky to pressure wash indoors, and we wouldn’t recommend it, but following all safety guidelines can prevent the worst outcomes. Always make sure to use an electric-powered machine over one that’s gas-powered, remove obstacles that could cause tripping or falling, and keep appliances like hair dryers and toothbrushes unplugged and out of the way to prevent electrical hazards. 

If you would like the insurance company to potentially help you pay for the mold remediation, you need to inform the insurer. When you notify your insurance company, they may say that you need a mold inspection before receiving any money for mold remediation. It’s possible that the insurer would not pay for this inspection unless they find mold.

Checking for mold yourself is crucial, as catching mold in the early stages is ideal. Mold can appear green, brown, black, blue, or yellow. It can smell musty and can feel like velvet, leather, or cotton. 

Most often, mold grows near water damage. It’s best to inspect these places for signs of mold growth:

  • Basement: Look in corners, windows, carpet, closets, and around appliances. 

  • Bathrooms: Check around sinks, ceilings, and around toilets. 

  • Kitchen: Inspect around the sink, behind the refrigerator, and behind trash can.

  • Attic: Look near the insulation and near intake and exhaust vents.
