How Do You Get Rid Of Mold And Mildew On Drywall

How to remove and kill mold – Bleach vs vinegar

The first step to getting rid of mold and mildew in your home is to stop the source of moisture. Every living creature needs moisture in some shape or form in order to survive. Mold is no different to in this regard.

So, before you start removing the mold from your drywall, you need to stop the source of the moisture, whether it is a leaky window, or a pipe, if it is a roofing issue, or water vapor weeping through a concrete floor, you will have to fix the issue. If you do not then mold will start growing again immediately after it is removed.

Next, you need to gather your drywall mold removal gear. When you remove mold you will without-a-doubt stir up spores, and they will become airborne.

You need to wear protective gear, long sleeves, long pants, rubber gloves, a respirator mask, and safety glasses, perhaps a hood as well if you have long hair as you do not want mold spores getting in there.

You will also need to decide if you are going to try and save the wall, or just scrap the whole thing. Sometimes removing the whole thing is a more effective long term solution than the alternative.

If the wall is soft then moisture and mold has taken its toll and the structural integrity is just non-existent at this point.

You need to remove surface mold from the drywall first if you are going to attempt to make it safe. You will want to vacuum the whole area with a HEPA-equipped vacuum and a brush adjustment to ensure you break up the spores and remove as much as you can.

  • 1Keep the room well ventilated. To remove mold, you may need to work with chemical cleaners. Many of these cleaners can be harmful if inhaled and, as a result, you should keep the doors and windows open as you work. Never direct a fan of any kind into the room or you will absolutely spread the spores everywhere! A fan may be placed in windows facing outward to push bad air outdoors. You should seal off doors with plastic to avoid spreading the mold spores in other areas of the house.XTrustworthy SourceUnited States Environmental Protection AgencyIndependent U.S. government agency responsible for promoting safe environmental practicesGo to source
  • 2Protect the surrounding area. To prevent potential damage that could result if you accidentally spill chemicals or cleaners, protect anything that you do not plan on working with directly. Remove furniture and decorations to the other side of the room or out of the room completely. Cover the floor with newsprint or plastic drop cloth and tape the coverings taped in place. Keep an old rag on hand to catch any spills as you notice them.Advertisement
  • 3Choose a cleaning agent. Cleaning agents range from mild to potent and include both natural and chemical alternatives. If you have small children or pets in your home, you may want to consider a milder, natural solution over a powerful chemical one. If you have a more advanced mold problem, a stronger chemical may be necessary.
  • How To Check For Mold Inside Your Walls

  • Locate the center of the area most likely to have mold inside.
  • Shut off power to the area at the electric service panel.
  • With a pencil and straightedge, lightly mark a square approximately 6 inches by 6 inches.
  • Cut along the outline with a drywall jab saw.
  • Remove the cut-out and inspect its back for mold.
  • If there is no insulation in the wall, look at the back wall. Also, hold a small mirror inside and shine a flashlight on the mirror to inspect the back of the drywall.
  • If there is insulation, any mold on the drywall or studs will have spread to the insulation. So, the presence of mold on insulation usually means mold on other building materials.

    Whats Wrong With Wet Drywall

    Drywall is made out of gypsum and other additives. That makes for a relatively lightweight building material that is still pretty durable. At the same time, those components also absorb water. Soaked up water provides a perfect haven for mold to grow, and the paper backing of drywall contains cellulose which becomes food for the mold.

    Preventing toxic black mold growth and the spread of mold spores is a major reason for removing sheetrock that has experienced water damage, but its not the only one. Drywall loses a majority of its structural integrity when it gets wet, which is especially dangerous on a ceiling.

    Wet drywall also has to be removed from interior walls too though. Wall cavities simply do not dry unless the sheetrock is taken off and the cavity is aired out. Wet fiberglass insulation batts get heavy, and theyll start to slump down in the wall cavity creating large pockets of air loss at the top of the wall. This drives up both heating and AC bills.

    How To Remove Mold From Drywall

    If you spot mold on your drywall, it may indicate a larger mold problem in the stud space behind the drywall. And, mold on drywall has already penetrated the surface, so you cant simply wipe it clean. You will need to cut it out and replace it in this case. Follow these steps:

  • As with the painted walls, you will want to move everything away from the area and use plastic on the floor to protect it.
  • Youll need something to attach the new piece of drywall to, so use a stud finder to locate the wooden supports behind the wall.
  • Use a utility knife to cut out the section you marked. Do not use a power saw, as this can agitate the mold and cause the spores to get into the air.
  • To limit spread of mold spores, carefully remove the drywall piece and place it mold side up on the plastic.
  • Clean the cavity with mold cleaner to make sure youve gotten it all, and dry it thoroughly.
  • You will want to make sure your new piece of drywall is the same size as the one you cut out, so measure the length and width of the missing section of drywall and cut the new section to those measurements.
  • Attach the new piece of drywall with screws, apply a joint compound to patch seams, let it dry and sand.
  • Wrap up soiled materials in the plastic and throw it away.
  • Vacuum the room with a HEPA vacuum.

    If you notice mold on a drywall surface in your home, try not to panic. The truth is that mold can happen anywhere and in any home. All it needs to grow is a source of moisture and an organic food source, and drywall can be an all-you-can-eat buffet. Read these steps on how to safely remove mold from your drywall.

    Mold spores are everywhere. They float through the air and can settle on any surface. If that surface is damp and theres a food source present, mold will grow.

    The paper face on a damp sheet of drywall can be the perfect food source for a spore to dig into. Before long, the mold can multiply and spread across the entire wall and into the wall cavity, feeding on wood framing and flooring.

    While its hard not to panic at the thought of a mold problem, you can handle most drywall mold scenarios on your own. According to the EPA, homeowners can remove mold on drywall under 10 square feet. Larger infestations might require a pro.

    Is It Bad To Have Mold On Walls

    Some surface mold can be easily cleaned but it is important to identify the cause of the problem and to act fast as mold on the walls isn’t good for your health or your home. Matt Kunz, President of Five Star Painting, a Neighborly company Kunz also recommends calling in a professional if you’re dealing with an area larger than 10 square feet.

    Mason comments, ‘If you have a black mold problem, you need to hire a professional who can test what you’re dealing with. If the mold is black and it’s toxic, you’ll need to remove everything that was affected, including drywall.’

    Otero adds, ‘If you believe that there might be black mold on your walls or ceilings, its important to check for signs of discoloration, moisture issues, and other changes in the structure of surfaces before taking any action. Have a restoration specialist come in and inspect the situation. If you have mold, it could be that water has come into the building, which could have come from a small leak in the wall, or the floor where water has migrated up the wall. You could also have a small roof leak, and when there is moisture and drywall, the potential for microbial growth life can exist. It is recommended to get an inspection as soon as possible,’
