How Much Mold In My Crawl Space Is Acceptable

Mold is a natural part of our environment, but it doesnt belong in your crawl space. Even a small patch rapidly spreads as it feeds on the structural components directly under your home.

Airborne mold spores can also migrate into the house and impact the health of everyone upstairs. There are no acceptable levels of mold in a crawl space.

Removing Radon Gas From Crawlspaces


We highly recommend getting your air tested for radon gas before beginning work to determine if any measures will be needed to protect your air quality.

Is It Hard Take Out Mold In Crawl Space

Building a crawl space instead of a basement is such a bright idea to save money it is beyond doubt, less expensive. The main advantage of having this is to add another space when it comes to storing the unused household appliances and allow the chilly air to circulate during winter. Still, it turns to be devastating without proper ventilation.

The house foundation is arguably the darkest place giving more opportunity for a tiny organism like mold to thrive. In fact, mold in crawl space can be ruinous and even have a high risk to humans health. Discarding the fungus varying in color and shape in the crawl space requires greater effort and seems time-consuming. Keep off your concern its not that hard.

Closed Cell Spray Foam For Crawl Space Insulation Keeps Out The Cold

Mold Spray in Crawl Space

After thirty years of enduring, Corby decided to have crawl space insulation installed. Having learned from his previous experience with batting, he inquired into two pound closed-cell spray foam insulation. An energy assessment by one of Sunlight Contractors BPI certified auditors verified what Corby suspected, he was losing heat through the floorboards.

Impressed with Sunlight Contractors competitive prices, Corby invited the crew out to install the closed cell spray foam beneath his home. One obvious advantage of two pound closed cell spray polyurethane foam in crawl space insulation is its adhesive property. Once Corey or another SPFA-certified crew member sprays the foam, it clings to the underside of the floorboards and quickly cures into a hard, firm substratum.

While an application of closed cell spray foam is a relatively quick procedure, which can be accomplished in most cases in one day, the crew at Sunlight Contractors takes time to ensure that they are meeting safety requirements. This means putting up caution signs to alert residents and neighbors of the spraying as well as suiting up in PPE, or personal protective equipment.

S For Cleaning Mold On Floor Joists In Crawl Space

Tackling mold in the crawl space and along the floor joists is a physical job. It takes a lot of scrubbing and the ability to squeeze into tight spaces. Because of these working conditions, you need the property safety gear and cleaning agents to get the job done quickly and without jeopardizing your health. Have the following personal protective equipment:

  • Goggles

You also need to gather cleaning supplies:

  • Plastic sheeting
  • Sponges/old cloths
  • Brush, putty knife, or small shovel

Before proceeding, you need to decide on what you are using to clean up the mold you find in the crawl space. Some individuals choose to make their own household solution cleaners. You can use ammonia, bleach, tea tree oil, or vinegar to remove the mold. You can also purchase a commercial-grade cleaner, such as a mold remediation company would use.

Whatever you decide to use, you need to be thorough and systematic in your approach to getting rid of the fungus. Here how to get started with mold removal:

  • Put on your protective clothing, gloves, or goggles before mixing up your cleaning solutions.

    One Of The Main Concerns For The Families We Serve Is Crawl Space Mold Removal And Stopping Mold Regrowth

    Most people are not aware that a large amount of air they are breathing inside the home comes from or passes through the crawl space. There are thousands of strains of mold growing in North Carolina and Tennessee. At Crawl Space Brothers, we rarely go into a crawl space that does not have some form of growth. White, yellow, and brown wood-eating mold are the most common.

    Fixing the crawl space mold issue requires two steps. First, killing the existing mold by spraying an anti-mold solution directly onto the colonies. Second, by hand cleaning all visible colonies from any surface in the crawl space, usually the floor joist and sub-floor. To treat the mold growth, we use an Earth-friendly agent, YCS Cleaner, that removes any mold, dirt, or other debris, while revitalizing and restoring the surface beneath.

    All the Crawl Space Brothers staff are personally experienced in identifying mold/fungal growth in crawl spaces and worked to treat and clean it. Having your crawl space inspected for mold growth by a professional who has done it before is always a good idea. We are your crawl space mold removal and moisture remediation experts.

Mold tends to form in materials that trap moisture, like wall paneling, paint, fabric, ceiling tiles, newspapers, or cardboard boxes. Any porous surfaces are also prone to mold. The humid environment is perfect for mold to grow and thrive. They can also be pretty persistent, coming back no matter how many times you spray or scrub. This is why its so important to choose the right mold killer and get rid of it for good.

    Some kinds of mold can be hazardous to ones health, so you may be liable if a tenant inhales toxic mold spores. Symptoms can include:

    • Weakness and fatigue
    • Lethargy
    • Loss of appetite

    Can Bleach And Vinegar Kill Mold In Crawl Space

    You can use both vinegar and bleach to remove mold from your crawl space. However, studies suggest that these liquids are not the ideal choice for cleaning a mold infested home. Remember, mold has already lowered the air quality in your home and you dont want to make the situation worse by introducing more irritants in the environment.

    On the other hand, an acid based cleaner such as vinegar can eliminate any remaining mold forever. All you need to do is drench the vinegar on a dirty floor using a pump sprayer. First, the vinegar will remove approximately 90% of the mold in your crawl space after which itll evaporate.

    If youre using the services of a professional cleaner, then the task becomes easier as they know how to kill dangerous mold in your Crawl space fast regardless of where it is. If you have to do the mold cleaning yourself, then read the provided instructions in each product carefully before proceeding to apply the same product on wooden structures, cement walls, and dirty floors.

    Do Mold Foggers Really Work

    Yes, mold foggers do work, though they probably shouldnt be your first choice when it comes to killing black mold. If the black mold has spread into a hard-to-reach area, foggers are mandatory. However, if the mold is in an easy-to-reach area, such as the wall or floor, youre better off using bleach or vinegar.

    The Truth About Bleach & Mold

    The Unless It Smells Like Bleach It Is Not Clean Misconception

    Amongst the Holiday TV commercials this weekend was an ad for a bleach company selling a kitchen cleaning product. The message was, unless it smells like bleach it is not clean. This was a move to cast doubt on the efficacy of better smelling, non-bleach cleaning products sold by their competitors. The commercial ended with something close to: unless it smells like bleach the germs are not gone.

    I get it, I understand advertising. The company is using a smell we easily recognize, calling it their smell, and connecting it to a result we all want: a clean and germ free home. But, does the smell of bleach in the air really mean the room is clean and safe? Will your mother-in-law walk into the house and think, wow, what a clean and germ-free place to be, just because it smells like a swimming pool?

    Labels on bleach-based cleaners clearly state that they are intended for cleaning hard materials. Germs or mold in porcelain sinks, on shower tile and Formica counter tops are probably cleaned away when you use these products. But what about the germs on your furniture, in the air, on the door and walls, or in the musty entry mat? What about all the porous materials in our homes?

    The real problem is that we fall for these ads and equate the smell test to being proof something is a universal super cleaner. Thinking, it smells like bleach, therefore it is clean, does not mean it truly is.
