When mold invades a house, some homeowners usually notice very small signs like a musty smell that lingers in the house while others may see a visible dark patch in corners of walls or near the ceiling. However, regardless of what the homeowners sees or perceives first, it’s important to confirm if it’s actually a mold that’s hiding in the house or if the patches observed are just random stains from dust or other dirt. It’s at this point that many homeowners either assess the situation carefully themselves or call a professional to confirm whether there’s mold in the house.
After confirming its mold through a professional or by careful observation, many homeowners jump into panic mode because of fear of what they assume comes with mold growth in a home; health issues, costly repairs and structural damage. What you need at this moment is not panic but a solution and the name of the solution is mold remediation. So, what does it mean? Mold remediation is a well structured professional method of eliminating mold permanently from a house or commercial property. It is a step by step process that is designed to identify, contain, remove and prevent mold from coming back to the building. Mold remediation is not usually done as a DIY task because of the risk of exposure and spread of mold spores to other people or parts of the house so it’s always best to leave the work for a trained mold detection expert. These experts have trained eyes and they know how to spot the hidden places that mold growth occurs. There are some cases where the mold specialist may even have to carry out mold testing just to understand the type of mold that is growing and how much it has spread into the space in your house.
It’s important to note that mold remediation is very different from mold removal. Mold removal is just one tiny step in the overall mold remediation process. If you try the DIY approach, you might be able to achieve mold removal, but guess what? The chances of the mold returning after a mold removal only process is very high.
So, if you’ve just been informed that there’s mold in your house, you don’t actually need to panic or rush into DIY mold removal, just call a professional to initiate the mold remediation process.
Let’s see all what happens during a mold remediation process and why each step is an important part of the entire process.
The First Step – Mold Inspection and Assessment
Before you start tearing out the wallpapers, scraping the paints on your walls or removing anything else, there’s one step you or the professional must not ignore and that step is mold inspection. This step is arguably one of the most important steps in your journey to mold elimination. You don’t need to rush this step. If you carry out inspection hastily, you might not get to catch all the affected areas in the building. It’s also a bad idea to assume that the mold hasn’t spread beyond a particular spot based on what you’re seeing. This assumption might restrict where the solutions will be focused and at the end of the remediation process you’ll find that there were places you failed to treat or were skipped. So, a thorough inspection is recommended if you want the remediation process to take care of the problem once and for all. Let’s see some important considerations during inspection.
What Inspectors Look For: During the inspection stage, it is advisable to look beyond the obvious spots where the dark patches are found. Some of the places that you should focus your attention are walls, ceilings, baseboards and any other hidden areas like behind furniture. When inspecting these places, the first thing you should be bothered about is moisture. Some people make the mistake of looking for stains during inspection but a visible stain isn’t all there is during an inspection. Mold often grows quietly without showing visible signs, so if your focus is on visible signs you’ll miss the areas where the problem is emanating. What you need to do is carefully search for areas where moisture is already present or places that have potential for moisture accumulation. The reason for this is that, without moisture, there’ll be no mold growth. Once you spot moisture, find out the reason for the moisture and take care of it immediately.
After you’re done looking for moisture, you can then hunt for the obvious signs like discoloration or peeling/bubbling paint. Some materials may not show peeling signs, so you might have to look carefully if they’re bent or warped.
Tools Used in Inspection: If you want to get reliable results during your inspection, you have to count on what your eyes tell you as well as what the tools are saying. The visible issues like stains, warping or peeling paints can be spotted with the naked eye but issues relating to moisture cannot. Moisture inspection is a lot more technical and it needs specialized tools that can measure moisture in places that the naked eyes cannot access.
One of the reliable tools you can bank on for moisture or leak detection within a wall or in other inaccessible places is a moisture meter. Another tool used for detection of cold spots or hidden moisture is a thermal imaging camera. Sometimes, you might need to use more than one tool to confirm the extent of moisture hidden behind a surface.
Why Proper Assessment Matters: You might be tempted to skip the whole inspection stage and jump to the cleaning or mold removal stage, but that’s exactly what causes an unending cycle of mold presence. If you rush the inspection and unluckily skip some of the places where the mold problem is coming from, the mold will find a way to return and spread either in the same place or somewhere else. In other words, a thorough inspection is non-negotiable. It is the foundation upon which every other step rests. A thorough inspection equals a lasting solution.
Testing the Air and Surfaces
After inspection, the next question that usually comes to the mind of most professionals is how terrible the mold problem is and to answer this question you’ll need to do mold testing. Although some people might argue that mold testing is not always necessary, which is true, but it also has situations where it can be helpful. Mold testing is very useful when the amount of moisture detected is low or when there’s no obvious signs of mold on the walls, ceilings or wooden materials.
During the mold testing phase, two things can happen, either the expert conducts an air quality test to understand what’s floating in the air or take samples from surfaces suspected of mold presence.
Air Sampling: Mold behavior is very predictable in many cases. When mold grows inside a property, it doesn’t just sit on the surface where it is growing, instead, it releases tiny spores that circulate with the air inside the property. To catch these spores or determine the concentration of mold in a space, you’ll need to conduct air quality testing or air sampling. This process is as easy as it sounds. It usually involves collecting air samples from inside the property that’s been tested and sometimes this sample is tested and compared with air from outside the house. If the concentration of mold spore inside the house is higher than that outside, then it means that something inside the building is contributing to the elevated mold level.
Surface Sampling: The second way to test for mold in a residential or commercial property is through surface sampling. This method usually focuses on visible signs and it involves using a swab to rub areas where mold is suspected to be growing and then taking the sample for lab analysis. Some professionals do not use swabs, instead, they do what is called tape lifting which involves using a tape to capture particles directly from the suspected surface. This type of mold sampling helps professionals to identify the specific kind of mold that is present. It’s important to note that not all mold types are dangerous; some are more problematic than others. If you know the particular mold invading your property, it’ll be easier for you to plan your next steps and solve the problem more precisely.
When Testing Is Actually Needed: As earlier mentioned, mold sampling is not always necessary, however, there are cases where it can help bring more clarity. If the mold issue is hidden or it is affecting the air quality inside your house, then testing can help remove the guesswork. Mold testing adds another level of confirmation. A lab test results confirming mold presence coupled with initial inspection that involved using a moisture meter and other tools makes it almost impossible to argue that mold is not present.
Identifying The Source Of The Problem (Water)
Mold needs a few key things to grow and without these things mold cannot exist, they are; moisture, organic materials, and comfortable temperature. Of all these, moisture or water is the major trigger. Moisture can come from obvious places like a burst pipe somewhere in the house or from a leaking roof during heavy rain. It can also come from less noticeable causes like humidity inside a building or from slow drips hidden out of sight. Whatever the case may be, mold won’t grow if it doesn’t see moisture.
Now that we’re done with mold inspection and mold testing phase, our attention should be on how to trace or track down the source of the moisture. This is where we’ll connect the dots between the moisture inspection we did earlier with leak detection. So, at this stage, we’ll be tracing each problem to its root. For instance, a damp patch on the wall might be traced to a plumbing issue (most likely a leaking pipe inside the wall). Mold growth near the ceiling may also be traced to a leak in the roof. Sometimes, there might be mold growing inside the baseboards and this might be traced to water seeping from outside or water rising from the ground.
There are also more severe situations where very large amounts of water are introduced into a building within a short period of time – flooding, burst pipe or storm. In these cases, you might need something like a water damage restoration service or even a flood damage restoration service together with the mold remediation process. The reason you need this is because, during flooding, large amounts of water sits in a place and if you don’t take care of the flooded place properly, mold would continue to grow there persistently.
If you skip this stage of mold remediation and jump straight to removing mold without fixing the moisture source, the problem will return again and again. It’s like scratching a problem on the surface, it’ll never be resolved permanently. So, before anything else, make sure you can clearly answer the question; where’s the moisture coming from?
Containment (Stopping Mold from Spreading)
Another thing that happens during the mold remediation process is containment. I know you’ll be expecting that after identifying the source of moisture then the next thing we should be doing is removing the mold affected materials from the house, but that’s not what follows, instead, our focus at this stage is how to prevent the mold from spreading. Mold can spread very fast when it’s disturbed in its resting place. If you touch a mold growth spot, scrape it or even walk through an affected area in the home, the microscopic spores will become airborne and land on new surfaces that were previously not affected. This makes containment not just a mere precaution but an important step in the entire remediation process.
The containment stage is usually of two layers- physical barriers and air control. We’ll discuss the second in the next section.
Physical Barrier: The first layer involves using physical barriers to seal off the affected areas. To achieve this, you’ll need to use heavy-duty plastic sheets to create a contained zone and this zone will usually cover the doorways, vents and any other openings. Your goal here is to make sure that everything inside the area stays inside. You have to make sure that there’s no gap for air in the contained area to get to other parts.
The containment process is one of the first stages that differentiates a professional remediation from a casual mold removal. A well executed containment makes sure the issue doesn’t get worse with an unintentional spread.
Air Filtration – Cleaning the Air You Can’t See
After performing the containment process, another important step is air filtration. This step is very important because molds are not just surface problems, they affect the air quality in the home as well. When mold is present in a home, there are airborne spores you do not see but they are right there lingering in the air and the only way to get rid of this issue is by air filtration.
During the remediation process, most professionals use systems that are highly efficient and such systems contain HEPA filters that can capture even the smallest particles of mold spores that could circulate freely in the air. You may not see these systems working because there is no dramatic change in the room but overtime, the difference becomes clear. As time goes by you will begin to perceive fresher and safer air.
Sometimes air quality testing is done after air filtration to ensure that the job is well done. Although the main goal is not just about passing a test, it’s about ensuring you have a space that feels breathable again.
It is very easy to underestimate the air filtration step because it usually looks as if all the problem is solved when visible mold is gone but the truth is, without proper air filtration, those invisible spores particles can linger, settle and even restart the problem. So it may seem like a simple process, but air filtration plays an important role in bridging the gap between removing mold and truly clearing the environment. Sometimes, what you cannot see also matters just as much as what you can see.
Removing Mold-Infested Materials
Aside from controlling the air quality, another important step is physically getting rid of the mold. This is usually where things start to feel a bit more real because there are several materials that have to be removed entirely from the home.
Porous vs Non-Porous Materials: When mold grows in a home, some surfaces respond differently from others. Some materials like tiles, glass or metal are usually non-porous so even if mold grows on them, it doesn’t penetrate deeply and with the right cleaning methods and an anti-bacterial treatment, these surfaces can be restored safely. But porous materials like drywall, insulation, carpets, wood, and even some fabrics can absorb moisture and when mold appears on them, it doesn’t just sit on the surface, it grows deep into the material itself. In the case of porous materials, cleaning the outside isn’t enough because the materials are already contaminated from within. This is why a professional may suggest cutting out sections of a wall or removing insulations from the home because they cannot simply be saved even by proper cleaning.
Safe Removal and Disposal: During this stage, you have to remove the contaminated materials carefully so that they do not release spores back into circulation. To achieve this, the materials are usually placed in tightly sealed bags before they’re taken out of the contained area for disposal.
If this process is being done in a larger environment like a warehouse or shared buildings, the containment area will usually be bigger and the removal process must follow strict containment and safety standards. This type of remediation is also called commercial mold remediation.
Deep Cleaning and Anti-Bacterial Treatment
After removal the next thing is to clean the area and this cleaning is more thorough than just a simple surface-wipe. The cleaning usually requires special cleaning solutions that are designed to break down or remove any remaining contamination from the surfaces. It is done in such a way that even the tiniest spores are scrubbed or wiped from all hidden corners.
The next step in this stage is careful application of anti-bacterial treatment. This helps to remove any lingering spores and it also reduces the chances of a regrowth. The cleaning and anti-bacterial treatment may not be as dramatic as the removal process but they ensure that there’s no surviving spores left in the area.
Drying the Area: At this stage the affected materials must have been removed, the surfaces cleaned and treated and the air in the space should feel fresher and lighter. So the next thing to do is to dry the surfaces. Remember that moisture is the trigger of mold growth or regrowth so you have to dry the surfaces thoroughly to ensure that there’s no leftover moisture that can facilitate a regrowth. This is where professional drying comes in. Most professionals use industrial-grade air movers and dehumidifiers to pull moisture out of the air, walls, floors and even structural elements. It’s important to note that drying takes time and that the goal is not just surface dryness but complete moisture elimination so you can create an environment where mold doesn’t strive easily.
Putting Things Back Together: When the professional has certified that the cleaned spots are fully dried, the next thing they do is to start rebuilding and putting things back together. At this point, walls that were torn open have to be closed, baseboards that were ripped off have to be replaced and places where paints were scrapped off have to be repainted.
Final Testing and Clearance: Before the curtain of the mold remediation process is drawn to a close there’s a need for one final step to confirm everything has been done exactly the way it ought to. At this stage, the professional focuses on testing for moisture and air quality within the space. Mold sampling is also done to check for the concentration of mold spores in the air. It’s good to remember that mold spores are naturally found both indoors and outdoors, but the concentration in the air should be on a lower side. If you have a high spore level indoor after the remediation process, then it means something wasn’t done correctly and the problem has not been solved.
The question you or the professional should answer at the end of this stage is- has the mold actually been dealt with? If the answer is yes, then we’ve come to the end of the remediation process.
Conclusion
When you take a step back and look at the entire process, one thing becomes clear—mold remediation isn’t just about cleaning a visible patch on a wall, instead, it’s a layered procedure meant to deal with air, moisture, mold affected materials and the unseen spaces in between.
The process usually starts with understanding the problem then it moves to control and removal and it ends with rebuilding everything back to the way it was or even better. A mold remediation process is counted as successful if the mold doesn’t return after it is removed.
