Does Mold Remediation Really Work?

Updated: Mar 16

Do you have a persistent mold problem that keeps coming back? Whether you’ve hired a mold remediator in the past or tried some DIY options to get rid of it, you may be asking yourself if remediation really works. With a wide variety of techniques out there, and even differing opinions on how to deal with mold, it can be difficult to know what works and what doesn’t.

Types of “Mold Remediation” That Don’t Work

There are many methods that people like to label as “mold remediation” that in reality don’t address the real problem. You may have heard that bleach is a sure-fire way to kill mold (Hint: It isn’t) or maybe you have even heard of “mold-killing” paint. These methods of dealing with mold simply don’t work because they only treat the symptoms and don’t get to the root of the problem.

Often when we hear people talk about how mold remediation doesn’t work, it’s usually because they have only treated the mold they can see while ignoring the underlying conditions that causes it to grow.

True mold remediation works, but it has to be done right or else the mold will just return time and time again.

So if you have to treat the causes of the mold and not just what you can see, what are the primary causes of mold and what will a good mold remediator do?

1) Water Issues

One of the most noticeable causes of mold is water. If you have leaks coming into your basement, flooding, or have had any sort of water damage in the past, then you need to deal with the water before you can treat the existing mold. Mold loves everything damp and wet, so if you have ever had water in your basement, there’s a good chance mold could be there as well.

A good mold remediator will check to be sure there are no active sources of water coming into your home, or water currently pooled anywhere. If there are, those need to be stopped before dealing with the mold. Additionally, any materials that have come in contact with the water need to be replaced.

2) Extra Moisture

There’s a reason why mold likes to grow in your bathroom! The constant moisture from showers creates the perfect condition for mold to grow and thrive. Any areas of naturally occurring moisture like extra damp bathrooms, condensation from heating and cooling your house, and even moisture from cooking in your kitchen should be checked. Making sure you have proper exhaust fans and dehumidifiers can help prevent mold from growing. One other place a mold remediator should be sure to check for moisture is your crawlspace. If there are pools of water, moisture along the walls, or anything that is damp, mold could potentially be growing there as well.

3) Humidity and Mold Spores in the Air

Did you know that mold spores can live in the air? And the humidity of your house can create the perfect environment for mold to grow and thrive there. So if a mold remediator treats the mold on your walls but doesn’t treat the air or prevent more spores from going airborne, then your mold issue is just going to return later. Proper mold remediation requires containment so, as you remove the visible mold, the spores don’t leave the area and grow in other areas of your home.

4) Remove the Existing Mold

Once the previous steps are complete, the solution for mold remediation is to physically remove any affected porous materials such as drywall and paneling, and to scrape the mold off any hard surfaces. This is the only way to truly remediate the mold that is already growing, and it’s important that this is paired with dealing with the underlying issues so you don’t continue to have issues down the line.

This can be a very in-depth process, especially if you have already tried other methods that cover up mold like “mold-killing paint.” In order to ensure all the mold has been removed, we first have to remove every inch of paint before we can treat the mold still underneath.
