How To Remove Toxic Black Mold From Wood!

The most common type of mold found in homes is mildew. Mildew is a surface mold that grows in warm, damp places like basements, laundry rooms, and shady porches. Mildew begins as a gray or white powdery colony and eventually turns black or brown. To test whether the wood is covered with mildew or just dirt, dab the stain with a cotton swab dipped in household chlorine bleach. If the stain lightens or disappears after two or three minutes, it’s mildew. If not, it’s probably just dirt.

Mildew can discolor and slowly harm wood surfaces. But there are much more dangerous molds that can damage the structure of your home. If a fuzzy or slimy black or green mold is visible and the drywall or wood underneath is soft or crumbles, there is irreversible rot. The damaged surfaces must be removed immediately.

Find The Moisture Source

Black mold is dangerous, and can greatly affect your health if left untreated, so it’s important to remove it as soon as you’re aware of it.

  • Water heaters. A small leak can create black mold in your basement or water heater closet.

How to DIY Wood Walls on a Budget

Building owners with mold infestation affecting more than 10 square feet should contact remediation professionals. Trained experts can implement limited or full containment if necessary to keep spores from spreading and intensifying a mold problem.

Mold infestations that affect a significant portion of a structure may require limited containment. This measure involves sealing off the infestation with a single layer of plastic sheeting with a slit covered by an outside flap to allow for entry and egress. Full containment for toxic mold or large infestations requires the use of double layers of plastic sheeting along with an airlock or decontamination chamber.

Remediation professionals have access to the cleaning equipment, PPE and restoration materials that are necessary to eliminate wood mold from any residential or commercial property. Valuable wood furniture or building materials may particularly benefit from the expert application of cleaning solutions and the use of commercial-grade equipment. This is particularly the case for expensive or rare articles or materials, waxed wood or wood with any other delicate finishes.

Major infestations in which the mycelium or root structure of mold penetrates deep under the surface of wood may lead to rot and ruin. Short of this, proper cleaning and restoration practices for wood furniture and building materials can eliminate wood mold once and for all.

Yours and the safety of those around you should be your number one priority when handling potentially harmful substances such as mold. Here are some safety tips when handling mold on wood.

  • Isolate the affected area- if you are working indoors, seal off the door to the room with plastic and any air vents. This isolation will prevent spores from traveling to other areas of the house.
  • Wear the appropriate personal protective gear- Mold can prove toxic when ingested or inhaled. Use special respirators, goggles, and gloves to help you prevent contact with the mold.
  • Careful disposal- put any materials affected by mold in a bag, seal it, and carefully dispose of it. These materials include any tags that you may have used to clean surfaces and unsalvageable materials.
  • If the HVAC has mold contamination, avoid running it.
  • Moisten moldy areas while you work to minimize the number of airborne spores.

Does The Building Need To Be Sterile Is The Object To Reach A Mold Spore Count Level Of Zero

No, the building does not need to be sterile, nor should you seek a “zero mold count”. We have worked on cases where sterility was a necessary cleanup goal: medical facilities such as in operating rooms and treatment rooms. But in a normal office or home there is always some airborne mold along with lots of other airborne particles in building dust.

No washing, sanding, scraping, or other surface cleaning will remove all mold spores from wood where mold was previously found. It is unlikely that most construction materials, even when new, are free of mold spores, nor is”zero mold” a reasonable nor possible objective.

Cleaning moldy framing lumber followed by application of a sealant may be the most cost effective alternative . While lumber replacement with apparently “clean” new lumber may sound appealing, it is likely to be cost prohibitive and in fact may include its own mold when it is unloaded at the work site.

Moreover, you can usually smell mold in a room in which it’s growing, and that’s why it’s important to get rid of it: Mold is toxic. Mold isn’t as difficult to remove from a wood ceiling as it is from a drywall ceiling wood isn’t as porous, so the mold tends to stay on the surface. Cleanup involves a trip to the attic and may involve some repair to the ceiling paint.


Put on a respirator, rubber gloves and goggles. You should also wear a protective over-suit that you can wash as soon as the job is finished. Turn off the central air system, cover the intake vents with plastic sheeting, and open the windows in the room in which you’re working.


Spread a plastic dropcloth on the floor. Scrape any loose or peeling paint from the affected area of the ceiling with a paint scraper and collect the paint chips on the dropcloth. Deposit the dropcloth in a plastic garbage bag and close the bag as soon as you’ve finished scraping. Vacuum the room and put down a new dropcloth.


Mix 2 cups of chlorine bleach and 1/4 cup of laundry detergent in a bucket with a gallon of warm water. Scrub the mold using this solution and a scrub brush. Be sure to clean all the discoloration from corners and edges of paint chips. Rinse the areas you wash with clear water and a sponge.




Remove Existing Mold From Wood

Once you’ve stopped mold from spreading onto other surfaces, like the new bookcase I bought at 10 p.m. in a panic, you’ll need to kill the original source.

  • With gloves and protective clothing move the particle board outside if possible, a well ventilated area without carpet if not. Scrape or brush the pressed wood to remove as many of the mold spores as possible.
  • After clearing the particle board from all the fungus, use the same bleach mixture to wash the pressed wood. If you used Clorox wipes like I did for your objects you’ll have to switch to this stronger mixture for the source of the mold. Since bleach can cause discolor furniture test the mixture on the back of your piece to see how it will affect the veneer.
  • Set the piece to dry completely, in the sun if possible. Strong fans in a ventilated, isolated space like a garage can be a substitute during bad weather.
