"Great customer service, working with Don, the owner. He is very professional and very thorough and makes you feel comfortable the whole time by giving you exact details of everything he is doing and price breakdowns as well which I really appreciate. I had to hire him for mold, remediation and air quality testing, as well as home inspection, and all of these jobs were thoroughly thoroughly detailed and I was highly satisfied. I would definitely hire him again."

"The tech who came out for test for moisture, Jared, was one of the best. Very friendly and very knowledgeable. He provided us with a lot of options. The company was very easy to communicate through e-mail and the entire project was quick. I reached out on Monday, they came by on a Thursday to test and came back the next Thursday and Friday to perform the remediation. Top notch!"

"On a whim I decided to check our radon levels in our basement. I guess I assumed this would have been done by the previous homeowner. Apparently one should never assume. My test game back at 5.9 pCi/L. The acceptable level is 4. And I wasn't going to chance my family's health. So I did my research on radon mitigation and sent a quote request through Angi's platform. I received a phone call the owner, John Spokis within 30 minutes on the Friday before New Year's. He explained the entire process and provided me transparent pricing over the phone and in writing via email same day. He was able to schedule us that Monday after New Year's. The installer Derek called me an hour before arrival to let me know he was on his way. He arrived on time, explained the work that was to be performed, reviewed the location with me and made sure I approved of everything before he started. The installation itself took about two hours. This included patching some cracks we had in our concrete at no additional charge. Frankly, I wasn't terribly excited about having a big white fan unit and pipe installed along my house. But I also knew that this was the optimal solution for our needs. And Derek took the time to make it look as neat and clean as possible. I really couldn't have asked for an easier or more pleasant installation at a very fair price. Oh and they guarantee after install that your radon will be 2pCi/L or below. They even give you a kit to test and make sure it has been lowered. There is a lifetime warranty on parts and labor that is transferable if you sell your home. And the fan has a 5 year warranty. So, if you have unsafe radon levels in your home. Don't procrastinate like I did. Just call Radon Systems and get it done in two hours. You'll be glad you did. I am."

Mold Testing and Remediation FAQs, answered by experts

Mold and other fungi love moisture, so the best way to prevent mold growth after water damage is to remove as much moisture as possible. First, find the source of the water or moisture, such as a leak or clogged gutters, and correct the problem. Next, remove standing water, vacuum up puddles with a shop vacuum, and run blower fans and dehumidifiers for 24 to 72 hours. Once you've removed all traces of moisture, disinfect the area using either vinegar or bleach to kill any remaining mold spores.

If the smell is closer to mildew or rotten eggs, the issue is probably mold or bacteria buildup in the machine or its drainage system. Clean your washing machine thoroughly, paying close attention to the rubber door gasket, as it can harbor odor-causing residue. Some machines have lint or debris filters that should also be checked and cleaned according to the user manual's instructions. Be sure to leave the machine's door or lid open after each use, as this allows for better air circulation and helps prevent mold growth.

Removing mold yourself can be dangerous. Always wear protective gear to cover your skin, face, and eyes, and wear a respiratory mask to protect your lungs. It is most recommended to only remove small areas of mold on your own and leave large mold growth to professionals. Mold growth can also be persistent. Without addressing the root cause, DIY surface cleaning can be ineffective and temporary.

According to the EPA, mold grows within 24 to 48 hours if left untreated after a water leak. So unless you notice the leak and stop it right away, you only have a day or so before mold is a real concern. If you don’t notice the leak, it can take about three weeks for the mold spores to become visible. That means you’ve likely had an active mold infection for a few weeks by the time you notice discoloration.

Yes, mold can grow on nonporous surfaces. Mold is extremely resilient and can survive just about anywhere. However, mold will not grow as quickly on a nonporous surface as on a porous one. Additionally, the nonporous nature makes it easier to remove. Keep the countertop clean and properly maintained, and you shouldn’t experience mold growth.
