      Mold Remediation Basics

      What is Mold?

      Simply put, mold is a type of fungus that thrives in areas with high moisture. While naturally present around you in the world we live in, mold only becomes a problem if it is a certain type. Mold comes in a variety of colors including green, black, purple, white, pink, and others.

      The vast majority of mold is harmless and usually can be found outdoors, such as on decaying leaves or grass clippings.

      Or on food in your refrigerator, like the green mold that shows up on old cheese.

      However, there are some varieties that you really need to watch out for.

      The most harmful type is a version of black mold called Stachybotrys chartarum.

      Here's what it looks like.

      Black Mold (Stachybotrys Chartarum)

      This incredibly dangerous type of mold is what most building owners find after a burst pipe or roof leak, as it needs constant moisture to grow.

      A byproduct of this type of black mold are mycotoxin spores, which are lightweight and travel easily through the air.

      When inhaled by humans and pets, the mycotoxin spores can cause serious health conditions like severe headaches, coughing, sneezing, skin rashes, and even death by blood poisoning.

      This is why it is absolutely vital to seek mold remediation services the moment you notice the issue.

      While the presence of mold can be easy to spot in some cases, it can be difficult to determine whether you have Stachybotrys chartarum in your building making it very important to call a qualified mold remediation company as soon as possible.

      What is Mold Remediation?

      The mold remediation process is a restoration process that involves finding the cause of the problem, dealing with it, and making sure it never happens again.

      That said, there are key elements to the remediation process to restore your commercial building back to where it was before the issue.

      There are a lot of interchangeable terms used among restoration professionals, so it is important to know the difference between them.

      Mold abatement is the process of removing mold from the structure and contents and encapsulating it. This may include tearing out parts of the building such as drywall and insulation, spraying a mold killer and following up with an encapsulant.

      Mold remediation involves a more comprehensive process. The process includes mold removal and an abatement strategy.

      Remediation also includes looking at the overall issue from a higher level to deal with the current growth and ensure it doesn’t come back.

      According to New York City Department of Health's Guidelines on Assessment and Remediation of Fungi in Indoor Environments outlining standard of care when it comes to dealing with mold:

      The goal of remediation is to remove or clean mold-damaged materials using work practices that protect occupants by controlling the dispersion of mold from the work area and protect remediation workers from exposures to mold.

      For business owners, mold remediation can help get your property cleared to return to normal operations.

      How to Prevent Mold

      Once you discover mold in your building… must take concrete steps to keep it from growing and spreading.

      It doesn’t matter if the issue is from a sudden water leak or some other past problem.

      For the safety of your building occupants, it is very important to take action immediately.

      Plus, quick action will help to minimize damage and remediation expense once you notice mold or mildew.

      In our blog, we’ve detailed the exact steps you need to take to prevent mold from growing after water damage.

      However, the short version includes the following steps:

      • Fix the Cause of the Water Leak: Once you’ve done this, it will make it easier for a mold remediation expert to come in and start assessing the situation.
      • Turn Off Electricity: Water and electric don’t mix well, so make sure to cut off power at the main breaker to the affected area.
      • Document Damage and File a Commercial Insurance Claim: Take lots of pictures of the issue and areas that have mold growth. Talk to your insurance company promptly.
      • Contact a Water Damage Restoration and Removal Company: They’ll help you start to dry everything out and ensure mold growth doesn’t happen.
      • Ensure Your Building is Completely Dry: Before the build back, you need to make sure all moisture levels are back to normal to prevent future mold growth and damage.

      Mold Remediation Process

      Mold Remediation Process Step-by-Step

      Of course, the mold remediation process is about far more than just removing mold from the damaged area.

      That’s the most important thing property owners should know about the mold removal vs. mold remediation process.

      To make the whole thing easy to understand, we’ve put together this step-by-step guide on what happens during mold remediation.

      1. Assess and Isolate

      The first real step in mold mediation is to assess the situation. A trained mold removal specialist (MRS) comes out to your building and determines what the next steps need to be. This is the most important time to document everything and ensure you’ve contacted your insurance company. Then they’ll look at the cause of the mold, where it is at, and what could potentially be hiding inside walls or ceilings. From there, they’ll isolate the problem and keep spread of spores to a minimum by using plastic or polyurethane sheeting.

      2. Suit Up

      While it will probably look like something out of a Hollywood movie, the special protective gear that mold remediation teams wear is for their overall safety. Often, this includes booties, goggles, and a respirator mask at a minimum. This shouldn’t alarm you, but is important to mention to show just how risky breathing in mold spores can be.

      3. Use Moisture to Suppress Dust

      It might seem counterintuitive to introduce more moisture to an area with mold growth, but it helps keep spores from traveling within the area. Your mold removal specialist may use a humidifier or other tool to create an ambient mist while the process continues.

      4. Removal of Affected Building Materials

      During this part of remediation, building materials affected by mold are removed. This includes drywall, carpeting, insulation, etc. The overall process is highly regulated by EPA standards that must be followed accordingly. Damaged items have to be packaged, sealed, and then sprayed down to eliminate any hidden spores on the outside of the bag. From there, the remediation team disposes of them accordingly.

      5. Cleaning the Area

      Any materials that cannot be removed are cleaned with a special brush and wipes using detergent solutions. This is one of the more difficult aspects of the mold remediation process and usually stirs spores into the air. All used cleaning tools that cannot be disinfected must be disposed of according to the guidelines in the previous step. If the HVAC system is affected, special tools and treatment methods will be used to clear any problem areas.

      6. Contents Restoration

      Though any type of property damage has the potential to ruin certain belongings, contents restoration technologies have advanced to a point today where many items are also salvageable. Usually near the beginning of the mold remediation process, a contents pack out will occur. This consists of a restoration company removing saveable contents such as textiles, clothes, hard goods, photos, electronics and more, and taking them off site to restore. Not every item can be saved, but some can.

      7. Biocide & Encapsulating Products

      Next, the mold remediation team may a special chemical called biocide to the entire space. This is a liquid that is approved by the EPA to kill mold spores. Generally, it must set overnight before being deemed fully effective. Then the mold remediation team applies a special mold resistant coating encapsulating product to the affected space. This stops mold from coming back and will prevent future infestations. Of course, this assumes the issue that caused the leak in the first place is handled and moisture levels are completely back to normal.

      8. Egress Areas are Sanitized

      The team then starts to take down and dispose of any plastic sheeting between the affected space and the rest of the building. They’ll likely use a HEPA-approved vacuum cleaner to ensure any spores that escaped during previous steps are fully killed.

      9. Complete Drying of the Space

      To keep mold from coming back in the future, your mold remediation and damage restoration company will use dryers, fans, and other tools to ensure the room meets a certain humidity standard. This is incredibly important, as the wrong level could allow the mold to grow back and defeat the purpose of the whole process.

      10. Post-remediation Clearance Testing

      After all that effort, a trained mold remediation expert will re-inspect the area. They’ll look for humidity, moisture readings and visual cues that ensure the mold problem is eliminated for good. They will also test airborne spore samples inside and outside the remediated area. These are necessary steps to properly assess whether or not the mold remediation was successful. Clearance testing ensures the success of the mold remediation efforts and also documents that the areas remediated are safe for reconstruction & occupancy.

      Communicating with building occupants is an important part of any mold remediation project. The building owner or management should notify occupants about the scope of the problem along with planned remedial steps that will take place. Occupants should also be given a copy of any inspection reports upon request.

      Reconstruction & Build Back After Mold Remediation

      After issuance of a clearance testing certificate, reconstruction can begin.

      Construction services to build back the building structure commences.

      This could include electrical, plumbing, drywall, finish materials, etc.

      A full-service restoration company will help you through the entire process.

      Mold Remediation FAQ

      How fast does mold grow after a water leak?

      According to FEMA, mold and mildew can grow twenty-four to forty-eight hours after water damage exposure.

      If you’re thinking that is incredibly quick…

      We agree.

      Think about this for a moment.

      What if you own a commercial building where everyone is gone on the weekend?

      By the time employees arrive on Monday morning and discover a problem…

      ...there is already a major mold issue.

      What are the signs I might have mold in my building?

      Besides the obvious visual cues that you have mold…

      ...there are other ways you can tell there’s a growth problem.

      If you’ve had a major leak in the recent past, it is a good indicator you might have mold.

      Bubbling paint, a musty odor, and soft spots in floors could mean there’s a presence of mold.

      And health conditions like a cough with no cold or headaches might also mean there’s an issue.

      Ultimately, calling a dedicated mold remediation company for an inspection is the only way to know for sure.

      What is black mold and why is it so dangerous?

      As we mentioned above, Stachybotrys chartarum is the most dangerous kind of black mold.

      It can cause extreme health issues for even moderately active adults.

      But in children, seniors, and those with compromised immune systems, it could be potentially lethal.


      Not all black mold is dangerous.

      The trick here is that you really can’t tell with the naked eye.

      And that’s why calling a mold removal company is so important. 

      Can I just remove the mold myself?

      Some guidelines suggest remediation efforts can be conducted by trained building staff on small affected areas (under 100 sq.ft.) as long as personnel receive training on proper cleaning methods, area protection, HVAC protection, disposal requirements, personal protection equipment and potential health hazards associated with mold. If you are not 100% prepared to handle even a small job, don't risk it.

      It is never advised to attempt to handle a major mold problem by yourself. First, the process requires numerous steps outlined by the EPA for safety. Second, bleach alone will not kill a large mold infestation.

      Due to the potentially harmful health effects of black mold, we highly advise you contact a professional and do not attempt to handle the problem yourself.

      When is mold remediation required?

      If the area affected by water damage in your building is more than ten square feet, you’ll need to contact a mold remediation specialist.

      Best case scenario?

      They come out and let you know that there isn’t a significant amount of mold growth.

      Worst case?

      Your building has to undergo the entire mold remediation process, as outlined by EPA guidelines for commercial buildings and schools.

      Either way…’ll rest assured knowing your tenants, staff, and customers are safe from health problems associated with mold exposure.

      Can you remove mold from furniture and other building contents?

      There are many ways to remove mold from furniture and other building contents.

      Often, this requires special cleaners and solvents to fully eradicate any hidden spores.

      The mold remediation company you hire will know what the process should be for the particular item you’re trying to save.

      What mold remediation certification credentials are there?

      At RestoreMasters, our crews are certified for the safe and effective inspection, removal and remediation of mold.

      A few of the most standard credentials for our industry include Certified Mold Remediator (CMR), Mold Removal Specialist (MRS), Council-certified Microbial Remediator (CMR).
