Is It Dangerous To My Health
While mold is a natural and necessary part of the life cycle, you dont want it in your house. It sprouts up easily, spreads fast, and can be difficult to keep permanently out of your home once its taken root.
This fungus can cause adverse health effects in human beings. It can exacerbate allergy symptoms, it can cause irritation to the skin, nose, and eyes, and it can worsen asthma. For those suffering from respiratory conditions, its imperative that living spaces be pro-actively resistant to mold.
Cleaning The Contaminated Area
Mix 1 cup borax with 1 gallon of water in a large bucket. For small areas, fill a spray bottle with the solution and douse the affected area. Alternatively, work out of the bucket for larger areas. Dip a brush or broom into the solution, swab it across the subfloor, then wait for 10 to 15 minutes to allow it to saturate the mold. Scrub with the brush or broom before reapplying it and wait another five or 10 minutes. Scrub a final time.
For the wood flooring youve already removed, treat and scrub it with fresh solution. Wet the moldy boards and wait about 10 minutes before treating. Then, apply a second, lighter coat of fresh borax water and scrub again.
Spray both the subfloor and wooden flooring again with a light layer of fresh borax water. Allow this treatment to dry a day or two at minimum. Once the material is dry, the borax residue will continue to inhibit the mold. Replace flooring and reapply clean or new trim. Treat moldy items removed from the house with the borax solution before bringing them back inside.If you have any further questions or concerns regarding removing mold from underneath the floor or feel the job is too big for you to do on your own, dont hesitate to contact a mold remediation specialist.

Once we have physically removed mold from a building surface by wiping or vacuuming, stains may remain. Don’t panic about those marks. Microscopic examination of stained wood fragments will generally show that what remains inthese wood cells are sterile fungal hyphae.
If the wood surface is cleaned thoroughly and building leaks, high moisture, or other water sources are prevented, keeping the humidity at the proper level, growth of problem mold on the cleaned surfaces is quite unlikely.

The Cause Of Moldy Floor Joists
Many are aware that our homes basement can be prone to poor ventilation, excess moisture and mold. However, an area that is often overlooked is the subfloor, as well as the floor joists. Your homes floor joists, sometimes referred to as the basement ceiling, can hold much more moisture damage than other areas of the basement. Oftentimes in an unfinished basement, the foundation walls and floor joists are exposed, leaving them more vulnerable than that of a finished basement.
The average subfloor and floor joist is made of wood, which is a porous building material able to hold a lot more moisture than foundation walls, which are generally made from cement. Compared to other areas of the home, basements tend to harbor more moisture due to poor ventilation. Moldy floor joists can be caused by excess humidity, leakage that has seeped from upper levels of the home, and condensation, among other things. The good news is that moldy floor joists can usually be effectively remediated without having to be completely removed.
How Much Mold Must Be Removed
Following a properly executed mold cleanup, if there is a future mold problem in a building it is unlikely to be due to having left behind an “inoculation” of problem mold, and more likely to be due to a new building leak that was left unattended.
Good practice for the extent of and means of physical removal of moldy debris varies by material.
For drywall we remove all visibly moldy material and continue removing drywall to no less than the next adjacent stud, rafter, or joist.
For fiberglass or other porous building insulation which has been wet, we remove all suspect insulation and all insulation within 24″ of the suspect material. However if moldy and wet conditions were long-standing in a building, removal of all of the insulation may be necessary.
For building insulation that has been exposed to dusty conditions or high levels of airborne mold it is often more cost effective to simply remove the material, clean the surfaces, and re insulate than to spend that same money on testing the insulation for mold.
Generally it is less costly to remove and discard more material than to “finish” the job and then discover that it needs to be done over again because the initial work was insufficient.
Framing lumber, or roof or wall sheathing that is not rotted does not need to be replaced. Unless framing lumber has been actually damaged, such as by rot, replacing it due to mold contamination is not justified and wouldbe improper.
