Mold Mildew Cleaning

Learn about the difference between mold, mildew, and fungus, and how to ensure it is properly remediated from your property.

Mold Mildew Fungus Cleaning in Nashville

So you’ve been told or think you have mold, mildew, or fungus. What’s the difference? Is one worse than the other? Should you panic?

Most mildew is mislabeled by people who either don’t know much about fungus or are trying to minimize any fear of mold. Mildew is usually a type of mold, but is not always, and grows in a flat pattern. Both mold and mildew are classified as fungi. 

The specific language matters when it comes to ensuring proper remediation. If you have growth on wood or drywall, it’s mold.

Brown Rot and White Rot

You’ve been told that you have brown rot fungus or white rot fungus. What does that mean? It means that, unless you can get them to show you lab results, the pest control salesman knows enough to not tell you that it is mold and get in trouble. He tells you he can sell you a solution for mold by calling it fungus, “treat” the mold according to his pest control company’s standards, and put your worries behind you

This method costs less than proper mold removal, but it does not meet the S520 Standard for Mold Remediation and won’t solve the problem. In the end, he makes money, but this route ends up costing you more in the end because it is a rip-off and will not pass any competent 3rd party Post Remediation Verification (PRV). Whether you are being told it’s fungus, mold, or mildew, always ask if they follow the IICRC S520 Standard for Mold Remediation and ensure any mold (fungus) remediation company you hire agrees to follow these standards.

Mold, Mildew, and Fungus Treatment

So all mold is a fungus. All mildew is a fungus. But not all fungus is mold or mildew. Fungi also includes mushrooms, lichens, smuts, yeasts, and rusts. Are all fungi bad? It depends. Fungus decomposes their hosts, which is a very “green” thing to do, otherwise, everything and everybody would die but not decompose/recycle. Compost piles rely on fungus. Dirt relies on fungus.  Mildew lets natural selection promote the strongest strains of vegetation to live. Is that bad? The question is, “how much does fungus (mold) affect your living environment?”

Condition 1, according to the S520, is the level of mold in our indoor environment we have come to accept as normal for most people. A little mold growing on the window sill just needs to be wiped off, although, the relative humidity and HVAC may need to be investigated. Bigger projects may require an ACAC Board Certified Mold Remediation Professional like Tier Restoration.

What People Are Saying About Us

Derrick Miller

TOP notch folks. Called and got an immediate response. I called them in a hurry and they showed up the next morning to do a mold test. Very helpful and professional and I will use them again!!!

I had nothing but a wonderful experience with Tier. They were on time,very friendly and knew exactly what they were doing. I had a spot that I'd had for 4 year on my carpet and figured I would have to replace that carpet but they got it out after a couple of tries. I was truly amazed. Alex, the manager, I'd worked with before and I can't say enough good things about him. He's always there when you need him with a solution for whatever your problem is. He has a very positive attitude and is great to be around. All in all my experience was fantastic!

Josh Morris

I honestly believe you won't find a better company to work on your home than TIER. Alex has always given me more than fair estimates and exceeded all my expectations with the final product.

Most recently, TIER installed an interior french drain in my house. Alex came out to my house through all stages of the project. He even did a final walk through and decided that he was not satisfied yet and told me he would send his guys out to bring it to his standards. I can't stress how rare this is.

Until working with Alex and TIER, I had not found a company in Nashville that I trusted. They are the only company in Nashville I would feel comfortable recommending to a friend.

Greg Lewis Tier Restoration is committed to doing the best work. The company's slogan, “Experience The Next Level” really describes Greg's work ethic as a professional in his field. He is a great resource for folks who need help with their homes. Greg and his team are folks to be trusted!

Monte Mohr

I've been selling homes for over 30 years and have owned rental properties for over 10 years. Tier Restoration is by far the best company of its kind I have ever used. As a real estate Broker selling hundreds of homes a year it is empowering to have a company as competent and professional as Greg Lewis and his crews. As a landlord I have personally used them twice in the past 12 months on major situations. The kind of challenges that would cause many to lose sleep over. In both cases Alex took my fear and concerns I was facing and extinguished them all by his consistent timely communication and professional awareness throughout the process to completion.
From simple duct cleaning to major foundation and crawl space repair and remediation there is only 1 company that I call. They are simply the best!

The Evans Family

The Tier group were amazing!! From the moment they walked in my front door, I knew we were going to be in good hands. The work was professionally done, and the communication was outstanding. Don't waste your time looking at other restoration companies, choose Tier and have that peace of mind that we had!!

Tracy Snow

Alex and his team are amazing to work with. Everyone is courteous, on time, and thorough in their work. Alex stops by to personally check on his crew and talk with the homeowner. I highly recommend Tier Restoration and will certainly use them again and again.
