Proven Ways To Remove Mold From Wood. How To Remove Mold Inside Walls

There is more than one type of mold that can be lurking along the floor joists or in the crawl space. Knowing what you are dealing with helps you decide on how to get rid of the mold and fix the problem.

It is likely that if mold is present in the crawl space, you will find clusters or patches of white dirt or powder on the girders, posts, or floor joists. These species have a fuzzy appearance and are more commonly found in the spring, summer, or fall months. Black mold varieties are not fuzzy or powdery, generally appearing as a flat, greenish or dark gray patch. Yellow mold can eat at the wooden structures of your home and cause serious decay.

What Causes Mold Growth On Floor Joists

Wood is a porous building material, and thats what makes most floor joists. Moisture can quickly infiltrate into the fabric, resulting in structural deterioration.

Moisture damage is the catalyst for the growth of mold. To learn more about mold growth, check out how to identify black mold. Excessive moisture, which is frequent in basements because of inadequate air circulation, is also one of several wetness causes.

The thought of trying to keep mold from growing on the floor joists and in your basement can be a bit challenging. Basements, more than any other part of the house, tend to accumulate moisture. Heres another guide on how to get rid of mold in the basement.

Keep an eye out for mold or mildew growing between the floor joists in your crawl space. As well as causing additional problems, mold and mildew can also cause diseases and illnesses. As spores out from crawl space make their way into the floor area, they cause breathing problems and foul odors, affecting well-being.

Is White Mold Dangerous

While mildew and similar types of mold are less of a danger and more of a hindrance, white mold is a health hazard. Inhalation of white mold spores, especially over a long period of time, can cause mold-induced asthma, allergic fungal sinusitis, allergic bronchopulmonary aspergillosis , and hypersensitivity pneumonitis.

Lets look at the health effect of mold in greater detail:

  • Allergenic molds cause allergies as well as asthma. When you come into contact with these types of molds, your respiratory system flares up. Around 20-30 % of individuals have a allergic reaction to mold that can lead to rhinitis, otherwise known as hay fever. Minor reactions are congestion, rash, and itchy eyes to very severe reactions of swelling, difficulty breathing vomiting, diarrhea, vomiting, and mental confusion.
  • Pathogenic molds are able to cause more serious diseases. For people that have weak immune systems, these types of molds can severely affect the persons already compromised health. Minor reactions are skin irritation, nail infections, and athletes foot while severe reactions are life-threatening infections of organs.
  • Most white molds tend to be allergenic or pathogenic. However, regardless of the type of mold you find growing in your home, you should always consult qualified professionals about how to remove the mold toxin from your home safely and effectively.

    Mold and mildew spores are all around us. Add some heat and humidity, and a colony of fungus will begin to grow on fabrics, shoes, walls, bathroom grout, and bare or painted 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 if 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 and the damaged surfaces must be removed immediately.

    1. Moisture Content of Wood

    First, lets look at the moisture content of wood. The Moisture Content of wood is the total amount of water present in the material.

    When mold spores are floating around in the air land on a wet piece of wood, lumber or any material that it can break down and digest, guess what?

    So, a piece of wood, furniture or other cellulose-based material that gets wet and is not dried within 24-48 hours provides the ideal habitat for mold to grow a rapid pace.

    To illustrate this, take for example a recent natural disaster, Hurricane Michael, that occurred in Florida.
