Commercial Mold Remediation: 4 Ways to Prevent Mold in Commercial Buildings January 9, 2020 – Posted in: Blog

Mold can be very challenging to deal with. They can sometimes be difficult to spot, they pollute the air, and they can even threaten the structural integrity of your establishment.

It gets even more problematic with commercial properties since they can cause business interruption, make you, your employees, and your clients sick, and of course, cost you a lot of money.

Fortunately, it’s very easy to prevent if you just know-how. Plus, doing so doesn’t cost much. In this article, we are going to talk about commercial mold remediation: tried-and-tested ways on how to do deal with mold for commercial properties. But first, why don’t we identify the different types of molds?

What Types of Mold Are Commonly Found in Commercial Buildings?

There are different kinds of molds, but there are five that are most commonly found in both residential and commercial establishments:

  • Alternaria – These are spores that start propagating outdoors but are usually carried indoors by dry summer winds.
  • Aspergillus – Here’s a type of mold that propagates indoors more frequently. The problem is, this is also classified as a type of toxic mold that can be highly toxic when inhaled.
  • Cladosporium – This type may not be as toxic as the previous one, but can still be as equally deadly since this kind of mold is most known for causing asthma attacks.
  • Penicillium – This type is the easiest to spot with their greenish or yellowish color. They also prove toxic to inhale in large amounts. Fortunately, if not for them, we won’t have penicillin.
  • Stachybotrys – Finally, we have the very popular Stachybotrys, also known as the black mold. Any property owner’s nightmare. That’s because this is the type of mold that weakens the structure of your home and create a weird odor.

So you see, mold in homes are the same ones that will grow in your commercial property. Here’s another question we also get frequently: what’s the difference between mold and mildew?

You can easily spot the difference through their appearance. Mildew’s white and powdery, while mold is green and slimy. The biggest problem, though, is that mildew doesn’t do any lasting damage to a property, or at least not how mold can.

Mold doesn’t discriminate. Houses, stores, warehouses, even vehicles. If left to its own accord, you can be sure that it will consume your property little by little. Anyway, now that we are more well-acquainted with it, let’s find out what causes it?

What Causes Mold in Commercial Buildings?

Mold is primarily caused by uncontrolled moisture. That may come from a leaking roof or a loose plumb fitting. Their spores may also be brought in from the outside through air vents, air systems (both heating and cooling units), and more. Again, as we have mentioned above, mold doesn’t discriminate, but it loves to stick to more organic objects like paper products, upholstery, and wood.

How to Prevent Mold in Commercial Buildings?

So how does one prevent it? Here are some tips:

  • Deal with leaks. Whether that be coming from the roof or loose plumbing, it is important to deal with them immediately. It’s going to prevent water damage too.
  • Use a dehumidifier. Your establishment’s humidity must always be maintained and kept at no higher than 50%. We understand how it can be challenging to keep track, so your bet is to install commercial dehumidifiers
  • Ensure proper ventilation. Keep your air vents and air filters clean, and that the enclosed areas of your establishment are free of moisture.
  • Deal with flooding immediately. Don’t let stagnant water sit too long and seep into your wooden walls, flooring, and furniture.

That’s it, by keeping the tips we have shared with you in mind, we are sure that your commercial establishment will be free of both mildew and mold. We understand, however, that even with the mold control practices, these pesky fungi can still strike, as if out of nowhere. If this happens, then please read on to learn how to remove them.

How to Remove Mold in Commercial Buildings?

We will be sharing with you a quick step-by-step guide on how to get your mold problem in control, but we honestly suggest that you let it be done professionally unless you are adequately trained in commercial mold remediation.

  1. Let your area undergo a mold air test. A professional mold inspection will give you some insight into how much the contamination is in your establishment. Ask your mold remediation team to test other rooms as well, even those that you’re sure are not contaminated.
  2. Seal off the area. Once the area is determined, it will need to be sealed before decontamination can proceed. This will prevent the mold from spreading further as well as keep untrained personnel from accessing the said area and cause cross-contamination.
  3. Ready your equipment. You will need various commercial mold remediation equipment in order to begin such as air scrubbers, commercial air movers, industrial dehumidifiers, and more. There are also other products like mold cleaners and mold disinfectants that would be good to have.
  4. Commercial mold remediation. You can now start the process of cleaning infected surfaces and purifying your air.
  5. Test your area. Once you have finished the process, you may ask a certified mold inspector to do a mold toxicity test again in order to ensure that, indeed, it is free of mold spores.
  6. Clean your equipment. After you are absolutely sure that the area is clean, you must then move on to your equipment. Most filters can be replaced. If yours can’t, then you can sterilize them to make them ready for the next task and to avoid cross-contamination as well once you take them out of the sealed space.
  7. Maintain clean air. There are air filters and air moving machines that you can set to change your air at least every four hours. In this way, your commercial space will always be free of indoor air pollution.
  8. Maintain a clean space. Finally, you may now continue practicing the preventive tips we have shared with you above in order to make sure that your space won’t be invaded by mold again anytime soon. Regular mold inspection and testing are also key in order to catch the problem as early as possible next time.

Congratulations! You have just freed your space of mold contamination.

How Long Does Mold Remediation Take?

Finally, you might be wondering how long the entire process will take, especially if it means shutting off operations for a while.

This will depend on how serious your case and how big the infected area is. Don’t worry, you can ask your professional mold remediation team to make a detailed plan for you that includes the costs and dates of the entire procedure.
