How To Remove Mold From Wood Beams In Basement

This Is Under My Bed Frame That Made From Wood Any Idea What Is This Thank You

High humidity mold on basement joists

This looks like white mold growth. If the room is on a concrete slab, I recommend investigating the area for vapor emissions. If not, the problem is likely related to elevated humidity throughout the house. Depending on your climate, this can be dealt with either by increasing your ventilation or installing a dehumidifier. If the problem occurs during the winter months, increase ventilation. If it occurs in the summer, use a dehumidifier.

How To Clean Mold From Wood With Vinegar

Vinegar is capable of killing 82% of the various mold species out there and is an excellent DIY wood deck cleaner. For the remaining mold species that vinegar alone cant kill, many people have found great success in pairing white vinegar with baking soda. Use one of these home remedies for mildew and mold to eliminate it from wood surfaces.

To kill mold with vinegar, pour undiluted vinegar into a spray bottle and spray the moldy area directly. Allow the vinegar to sit for up to one hour. Wipe the area clean with a damp towel and allow the wood to air dry. The smell of vinegar will linger on the wood for several hours but will dissipate naturally.

Even if you dont have any mold, vinegar is a great ingredient to use when you need to clean wood siding that may be covered with ordinary dirt and grime. It sanitizes while it cleans and leaves the surface bright and shining.

How Can I Prevent Crawl Space Mold

Though mold is everywhere, it wont cause problems if you eliminate conditions that encourage its growth. Routine inspection can help you uncover issues that could create the perfect condition for mold to thrive.

If the crawl space is vented and not sealed, its about time you seal it and block all vents. Your open crawl space allows mold to come in attach itself to wood and other organic materials. Since this place is typically moist, its going to grow fast and infest the whole crawl space. Your basement and crawl space repair contractor is going to install a plastic vapor barrier that covers the entire floor and walls. It can go around barriers such as wooden beams and piers.

Check and remove damaged or torn insulation from the crawl space as its likely to get wet and harbor pests. Mold can easily attach itself to the damaged material. In no time, it can take over and spread to other parts.

Ensure that all water pipes and ducts that run through the crawl space are intact. Fix any pipe thats leaky. Take a step further and insulate your water pipes to stop condensation during cold winter weather.

Cracks on the crawl space wall may also encourage moisture and water to seep in. And thats bad news as it will also encourage mold to grow. Typical repairs may involve applying crack injections to seal up crevices on the wall.

How Do You Clean The White Mold Off And Keep It Off Its On The Bottom Of Wood Doors And Trim And Cabinets

Its critical you first identify the cause of the mold. Without addressing the underlying moisture source, the mold growth will return. No chemical can prevent mold growth if elevated moisture is present. In time, the mold will simply grow on top of the new dust that settles on top of the cleaner/coating.

Assuming the area of mold growth is fairly small, the mold growth can be scrubbed off with a detergent/water solution. More powerful chemicals, such as bleach or quaternary ammomium compounds are necessary to kill the mold. However, because youre physically removing the mold by scrubbing and wiping, the killing power of the cleaner is not necessary. White mold growth can typically be removed without leaving lingering staining. If staining is visible after scrubbing, youll have to sand and refinish the material to address the discoloration.

Monitor The Affected Area Over Time

Once youve found mold and had it taken care of, whether on your own or by a professional, keep an eye on the area to make sure it doesnt grow back if it does, the moisture issue was not resolved properly and will need to be redone. If you did it on your own and see it grow back, youd do best to hire a professional to take it on the second time.

Reader Question: How Should We Clean Moldy Wood Framing In Our New Home

We are building a new home, the wood framing has mold, the walls are still open. How should the builder clean or remove the mold? – Linda Lewis 4/7/2013


Thanks for the question Linda.

If the mold is ONLY the cosmetic black mold that we describe

at BLACK COSMETIC MOLD then it really is only cosmetic and could be left in place.

There are two difficulties with this:

  • First you may have trouble recognizing the cosmetic mold I describe in that article, though sometimes the growth patterns make it clear. To address this you could spend roughly $50. to send a representative tape sample of the mold to a mold test lab for confirmation.
  • Second, while the black mold I describe is indeed harmless on framing lumber and virtually always came in on the lumber from the lumber yard, also one wants toWatch out: in some cases, particularly on lumber that has been wet, or on treated lumber, my own field and lab tests have found Aspergillus sp. and Penicillium sp. growing among the harmless black mold.

So we might want to clean the lumber.

I tend to stay away from labor intensive approaches and from incomplete approaches . Keep us posted and send along some photos if you can as what you learn may help others.

While most people tend to focus on black mold, also known as Stachybotrys, only a few are concerned about white mold growing within a building or home. However, white mold can also be very dangerous and should be dealt with as soon as possible.

In this article, we will outline the best ways to identify white mold in your home and remove it safely.


What Does Mold Look Like

We like mold for making a tasty cheese, but we dont want it downstairs. To find it, you might have to dive deep and get behind surfaces. Indoor mold doesnt necessarily look very menacing.

It comes in all colors from white to green to black. You might have heard about black mold , but in truth that type of mold isnt the most common one found in homes. Four other types are much more common, according to the Centers for Disease Control , and they include Cladosporium, Penicillium, Aspergillus, and Alternaria. The type that creates black mold is technically Stachybotrys chartarum .

One thing they all have in common is their favorite types of places to grow, which the CDC notes can include wet cellulose materials, including paper and paper products, cardboard, ceiling tiles, wood, and wood products, as well as dust, paints, insulation materials, drywall, carpet, fabric, and upholstery.

We Moved Into Our House A Year Ago Its Only A 3 Year Old House We Just Noticed What We Think Is White Mold On Many Of Our Stored Items Throughout The Basement Is This Mold And Should We Call A Professional Or Try To Do It Ourselves I Keep Finding More And More Items With This Substance On Them We Recently Had The Basement Fogged For Fleas As Well If That Makes A Difference

This is due to elevated humidity in the basement. Typically this occurs due to a lack of heat during the winter months. The lower temperature leads to increased humidity, which in turn causes the mold growth.

The easiest solution is to simply increase the temperature of the basement. Also, install a relative humidity gauge in a central location. Your goal is to keep the RH under 50% during the winter months.

In addition to increasing the temperature, you might need to actively ventilate the basement. Running an existing bathroom exhaust fan can achieve this. If no bathroom fan exists, you can install a wall mounted exhaust fan.

How To Get Rid Of Black Mold

Some places to find black mold are bathrooms, basements, and crawl spaces. The best way to identify black mold is how it grows in a circular pattern, its black color, and it grows in patches that resemble dots. On dry surfaces, it looks very similar to soot, while on a wet surface, such as shower grout, it looks like slime.

If you notice mold of any kind, you need to ask yourself what gets rid of mold. There are numerous homemade cleaning solutions you can use to kill the black mold some may work better than others. The key to cleaning black mold is to pick one cleaner and stick with it.

Mixing cleaners, such as bleach and ammonia, can cause adverse chemical reactions. Never use bleach or hydrogen peroxide when removing mold from upholstery.

  • 1 cup bleach mixed with one gallon of water
  • 1 teaspoon tea tree oil and 1 cup of water
  • 2 parts water mixed with 1 part hydrogen peroxide
  • 1 cup Borax mixed in one gallon of water
  • Pure distilled vinegar

Select your homemade cleaner and apply it to the black mold. Allow the soap to soak for about 15 minutes. This allows the cleaner to reach and kill the roots and takes care of removing black mold to prevent it from coming back.

Scrub porous surfaces with a bristled scrub brush to work the detergent in. Rinse the area with clean water and check to see if all mold is gone.

If mold is still present, repeat the cleaning process. If mold is gone, dry area with a towel or squeegee to remove all excess moisture.

The Difference Between Mildew And Mold

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.

Guide To Cleaning Mold From Smooth Wood Surfaces

Pittsburgh, PA Moldy Floor Joist

Perfectly adequate moldy-wood-surface cleaning may be accomplished by wiping or power-washing or media blasting.

Where wiping a moldy surface, take care not to spread moldy debris from a moldy surface onto a previously uncontaminated surface by making the mistake of re-using the same moldy rag over and over on all surfaces. Professionals use “steri-wiping” which takes care to avoid spreading moldy debris by always folding and using a clean side of the wipe when moving to a new spot.

Where the framing lumber is indoors or otherwise in a location where water spillage is a concern, wipe theareas of heaviest mold to remove any loose mold from the surface of the lumber.

Unless professional area-containment has been set up , do not use violent cleaning methods such as power-washing or sandblasting indoors, as you will spread moldy debris throughout the building and you’ll increase the ultimate project cleanup cost.

Wherethe framing lumber is outdoors where water spillage and the creation of aerosolized mold spores is not an issue, pressurewash the infected lumber to remove surface mold.

“Cleaning” in this case can be simply wiping with a sponge wet with water or detergent.

The object of cleaning is to remove most of the loose moldy particles.

A professional uses sterile wipes and folds to a clean side of the wipefor each wiping stroke. For a small homeowner non-critical project this may be overkill but think about and avoidspreading moldy debris by your cleaning procedure.
