Knowing How to Remove Mold from Wood and Drywall is something every owner should know how to fix. And as a homeowner or property manager, mold is one of the last problems you would want to leave untreated.
Because of their porous nature, most building materials absorb moisture. This action provides the perfect breeding ground for mold to grow.
Beyond its ability to damage your property, mold can also endanger your family or co-workers’ health through spores and mycotoxins released into the air you’re breathing. So, learning to remove mold is important for your home and even more critical for your good health.
For these reasons, let’s learn how to remove mold from wood or drywall with proper cleaning methods – or, when mold has damaged a property, how to perform mold remediation as soon as you spot this fungus.
How To Remove Mold From Wood or Drywall:
While there are many different types of mold, and every infestation is unique, you can take some relatively simple steps to deal with common mold problems.
If you’re ready and able to tackle the work yourself, we’ve put together this essential guide to deal with the mold in your home or workplace and to walk you through the two different mold scenarios. “Mold Removal” (surface cleaning) and “Mold Remediation” (removal and disposal of building materials).
The first part of our DIY guide will cover Mold Removal (Cleaning), which addresses minor mold growth on surfaces that can be cleaned without removing the building material.
If you have a more serious problem, the second section of our guide discusses complete Mold Remediation, in which building materials must be physically removed from the structure of your home or workplace, followed by chemical treatment of remaining materials, to get rid of the mold.
Step 1: Identify the Type of Mold
One thing you should know before starting in on your mold problem is what kind of mold you’re up against. Some molds, such as Aspergillus, can cause damage to your home but are unlikely to cause disease in healthy people.
The Mold you need to be particularly careful about is Black Mold. This mold can be toxic and create a variety of health complications. Black mold is easily identified by its characteristic black color, as seen in this photo:
Because black mold is the most critical type of mold, you should prepare for removal as soon as you find it, and for that purpose, this article will predominantly focus on how to remove it.
Step 2: Identify the “Source of Moisture”
This is critical. Since mold only grows with the presence of moisture, you must first identify the source of the water that is causing the mold to occur. Once you have identified the source and eliminated the moisture intrusion, you can begin with Mold Removal.
If possible, with your conditions, it’s much easier and less expensive to remove mold itself from wood and other materials without actually removing (remediating) the materials from your home.
Small-scale mold removal of this type makes all the difference between your mold problem requiring a few chemical treatments and turning it into a full-blown renovation project.
Check out this short “How To Remove Mold” video – to see these mold removal techniques in action:
Once you’ve determined you have a mold problem – and have already eliminated the source of moisture intrusion, Here are 4 steps for Cleaning surface Mold before it becomes a significant problem.
“Surface Mold” Removal
Step 1: Identity The Mold Affected Surfaces
Remember that treating all of your mold growth at once will help ensure that the mold doesn’t begin to spread again once you’re finished. Because If you have mold in one place, there’s a good chance you have it elsewhere.
For this step, place a small piece of painter’s tape near but not on each mold spot you locate. This will help you quickly identify them later when removing mold in your house.

Step 2: Select Mold Cleaning Agent
There are several options for how to kill mold. But take note, using Bleach to kill black mold is a false statement. While bleach may inhibit mold growth, Bleach does not kill mold spores.
Instead, use one of the DIY combinations of household ingredients we recommend below, or better yet, use any of the many mold-killing chemical sprays, such as RMR-86 Instant, for sale on Amazon. They are pre-mixed mold killers and come with their own spray bottles.
For large-scale mold removal, you can also purchase a gallon Concentrate of Mold Killer, which you mix with water – and use in a garden sprayer.
Home Remedies: If you need to remove black mold from wood or drywall, you can use these home options:
1) mix 1 cup of Borax with 1 cup of water
2) baking soda with vinegar
3) Hydrogen peroxide with water
All of these are effective home product alternatives. Peroxide is a perfect option on drywall, as it can help to lighten the stains that mold creates when it populates a surface.
Other mold killer products such as Concrobium are highly rated and proven chemical products for removing mold. Concrobium is available online at Amazon, Home Depot, or Lowes and can be used on porous (soft) and non-porous (hard) surfaces.
Step 3: Spray Mold covered surfaces thoroughly
After placing on rubber gloves, and a safe, filtered face mask, you’re ready to begin cleaning off the mold. Thoroughness is crucial when removing mold from wood, drywall, or other porous surfaces. You want to be sure you are cleaning every spot affected by mold and the surface around it.
Spray and saturate all mold surfaces before moving to any other affected areas. Read and follow directions carefully for Chemical cleaner usage and safety precautions.
Be aware that mold spores can remain on a surface long after the mold is gone, so you should wash down everything around the moldy area.
Step 4: Use HEPA filtered Vacuum to Remove Mold Spores
Even with the most thorough cleaning, some mold spores remain near the moldy patch. For this reason, the final step of your cleanup should be vacuuming the room you were working in with a vacuum with a HEPA filter.
A HEPA filter should catch errant spores so mold growth doesn’t start again.
Note: If the Mold contaminated area you’ve encountered exceeds regular mold (surface) conditions, and you need to remove mold-contaminated building materials such as drywall, insulation, studs, flooring, etc., then Mold Remediation will be required instead of a Mold chemical cleaning process.

Mold Remediation: How To Remove Mold-Contaminated Materials.
The following seven steps will show you how to remove mold-affected building materials. However, if the contaminated material is more extensive than 10 square feet, you’re likely better off calling a professional to handle it. Please read the EPA guidelines for mold removal here.
Step 1: How To Identify the Source of “Moisture Intrusion”
Your efforts to remediate (remove) Mold contaminated materials will be in vain unless you first Identify and Repair the Source which caused moisture to intrude into your finished space.
Once the repair work has been completed, Test the area (roof, walls, plumbing) to ensure you have remedied the moisture problem.
Step 2: Wearing Mold Protection Equipment (PPE)
Black mold removal can be hazardous to your health once a room has enough mold concentration. If you’re at the point of remediation, you will need to get some Personal Protection Equipment (PPE)
This starts with a Tyvek cover-up, a professional-grade respirator, safety goggles, and thick rubber gloves.
Also, don’t forget to run a fan to exhaust air out of the room you’re working in to direct airborne mold spores outside and prevent them from spreading to other areas of your house.
Step 3: How To Quarantine Area With Mold
Before you begin to work on Black Mold affected areas: Close off all the vents leading to and from the space. Plastic wrap and painter’s tape should prevent air from moving into other non-contaminated areas of the house. Use a shop vac with a HEPA filter to remove loose mold spores before you begin work.
Step 4: How to Remove Mold from Building Materials
Once you have the right safety protection in place, use a shop vac and manually remove the flooring, drywall, or other material that has become mold-infested. Go slow, and be careful not to kick up too much dust, as the dust can carry spores with it.
Also, be sure you have a safe and environmentally friendly way of disposing of the material you remove.

Step 5: Spraying Chemical Cleaners on the Remaining Surfaces
Just because the surfaces with mold are gone doesn’t mean all mold spores have been eliminated. Before proceeding, you should wash down studs or other surfaces previously in contact with the material you removed with a mold-killing chemical.
If the affected material surface allows it, use one of the mold-killing chemicals discussed under “Mold Cleaning Agents” above. Again, our highest-rated suggestion for chemical mold killers is “Concrobium Mold Control.”
If you’re removing mold from drywall, check and remove or treat any wet or affected insulation and studs underneath, as these materials may also be contaminated by mold.
Step 6: Install New Building Materials and Cleaning Up:
Once the full remediation has been completed, you can replace the material you’ve removed from your house with new building materials and clean up any room you’ve worked in. As a final precaution, lightly wash all new surfaces once after installation to be sure you’ve killed all mold spores.
As with typical mold “removal,” you should use a HEPA vacuum with “remediation” to catch spores that weren’t hit with the chemical wash. For added peace of mind, you can also use an air purifier in the room for a few days to catch any remaining mold spores that may have been left behind.
Step 7: How to Confirm Mold Has Been Removed:
Once the full mold remediation has been completed and the site has been thoroughly cleaned up, you should monitor the work for a few weeks afterward to confirm your mold remediation work was a complete success:
Has the original cause for moisture intrusion been permanently repaired?
Has any mold, mildew, moldy odors, or moldy material re-appeared anywhere?
Not counting natural floods, of course; consider ways to control and prevent moisture intrusion and resulting mold in the future.
