Hello I Have This White/cream Colored Grown All Over My Home And Was Wondering If It Is A Type Off Mold No One Believe That
Its difficult to fully confirm from the photo. Does it have a fuzzy appearance? Does it wipe off with damp paper towel? If yes, its likely mold. If it is crusty or difficult to wipe, it is not mold. I recommend a tape lift style test to confirm whether it is mold. If the test is positive, hire a local inspector to identify the source of the moisture. Systemic mold growth like this is usually due to humidity. Buy an RH gauge and try to maintain < 50% throughout the home.

Peeling wallpaper can also be a symptom of mold. While some scruffiness and discoloration tend to eventually strike your wallpaper, unusual surface or peeling abnormalities such as crackling or bubbling can be a sign of wall moisture. And remember, a reliable precursor to mold is always going to be moisture. Make sure to pay attention to any warped areas that feel damp.
To keep mold from growing in your cooling or heating systems, you can have a specialist check them regularly. Another indication of mold in the house is dark grout between bathroom tiles. Even if this type is most likely the harmless type, there could be flooding in the adjacent room or a leak in bathroom plumbing that could produce a more toxic fungus type that only professionals can remove. A sample sent for testing will let you know whether or not your shower is harmless.
Mold could also be the culprit when you have pre-existent problems with breathing that after long periods at home seem to flare up. Many household species of mold wont affect persons that do not have issues with breathing. However, in individuals suffering from asthma, it could aggravate it. Consider a mold inspection and a doctors appointment if the problems with your breathing seem to get worse with no clear cause.
Common Causes Of Mold In Your Home
Mold can grow just about anywhere but is most commonly found in areas such as bathrooms, kitchens, basements, cabinets, and near pipes or ducting areas. It only needs a few elements to grow and proliferate throughout your home, the key element being moisture.
Mold behind drywall may be one of the most common household problem areas as drywall, wood, and cotton are ideal food sources.
Ceiling mold is also highly common due to a lack of ventilation and accumulation of moisture.
If the temperature is right, there is a moisture source and enough oxygen, you can be sure mold will begin to grow and spread.
Here are 10 of the most common causes of mold in your home:

How Fast Does Black Mold Spread
Mold begins to grow as soon as its spores land on a damp, fibre-rich material and it can spread around the house within 24 to 48 hours. It colonizes in one to twelve days and grows at one square inch per day. In less than a week, it can cover surface areas of several square feet.
Unfortunately in most cases, mold is widespread and already a big problem before a problem is even suspected by the homeowners.
Does Bleach Kill Mold
Yes, bleach can effectively kill/disable mold on hard surfaces. See this study. However, bleach has several negative characteristics Therefore, mold remediation professionals often use alternative chemicals such as quaternary ammonium compounds. Organic, plant based chemicals such as Benefect are effective as well.

- Increased humidity can occur in homes in many ways humid weather, continuous rain, cooking, showering, etc. To help prevent mold growth in your home, make sure your house is well-ventilated and keep the humidity below 55 percent.
- Insufficient ventilation leads to increased humidity, and thus, to mold growth and other problems like indoor pollution. Make sure to open doors and/or windows when practical and to use fans as needed.
- Leaking pipes are a common problem in homes and must be fixed immediately. Oftentimes, leaks are hidden from view, such as inside walls, so make sure to inspect walls for water stains regularly.
- Roof leaks are also a way for water to seep into your home and cause mold. If you see water stains on the ceiling, check for water damage in the attic and have your roof inspected and fixed as soon as possible.
- Condensation occurs when warm moisture-laden air comes in contact with cold surfaces. Condensation can be visible on walls, windows, concrete floors, or metal pipes. Reduce condensation by adjusting the humidity in your home.

Water, excessive moisture or dampnessare the key reasons that mold gets formed anywhere in a home. Mold never forms in the absence of water or moisture. If these occur for some reason in a home but are fixed right away, mold will not be able to form. It is only when the water/moisture related issue is not fixed within 24-48 hrs of its occurrence that mold starts forming and becomes a problem.
The common water related problems in a home that can lead to growth of mold are:

Where To Check For Mold In Your Bathroom
You may love a long, hot shower but, unfortunately, so does mold. The warm, wet environment of a bathroom is practically an invitation for mold growth. Bathrooms that lack proper ventilation are especially prone to attracting mold. While it may be clear to check for mold on shower tiles, there are plenty of less obvious places for mold to grow in the bathroom.

The Health Risks Of Mold
Along with being pretty unsightly, certain molds can pose major health risks. Some people are sensitive to mold as an allergen, and it can cause anything from eye and throat irritation to asthma or more serious illnesses in those with compromised immune systems.
In fact, indoor mold issues pose such a widespread problem, that the World Health Organization released an extensive report on air quality guidelines concerning mold. In the report, they noted that it doesnt take a flood event to lead to mold in a building or home, but in fact the majority of mold spores come inside via the regular airflow. These spores, when they find a moist spot to multiply, create issues of health-impacting poor air quality in these spaces where we all spend the majority of our time: inside.
Where To Check For Mold In Your Kitchen
From long-forgotten leftovers in the back of your fridge to the not so easily forgotten dishes that pile up in the sink, there are ample surfaces for mold to take up residence in your kitchen. The added levels of humidity from using the stove and running hot water from the sink can cause kitchen mold to grow quickly. Some of the most common places to check for mold in the kitchen include:

Moisture In Your Crawlspace
You might not have a full basement, but youll probably have a crawlspace under your home unless your place was built with a slab-on-grade. Confined crawlspaces contain optimum mold-growing conditions, and thats due to ever-present moisture thats not taken care of. Here are some common crawlspace moisture sources:
Lack of ventilation from passive cross-flow or mechanical means
Missing or compromised vapor barrier
Bare earth floor with no concrete skim coat
Leaky water lines or drain pipes
Disconnected dryer vents that pump humid air
Condensation in furnace ducts
Drain lines from condensation in high-efficiency furnaces
Rain or flood water
Holes or cracks in foundation walls
High ground water tables
Poor exterior grading that allows water to flow against foundation
Poor drainage on foundation backfill
Blocked perimeter and footing drain tiles
Will White Mold Cause Rot In Flooring Such As Sub Flooring And Floor Joists
Great question. Short answer = No, white mold will not cause rot.
Long Answer. Rot is caused by wood decay fungi. These are not considered molds and typically require much higher moisture levels to flourish. They also require much more time to grow. While mold can grow in a matter of days, wood decay typically requires months of saturation.
The prevention strategy is the same for both get rid of the excess moisture.
While there are many thousands of types of mold, only a few types of fungi cause wood rot. If you observe white mold growing on your subfloor, that mold will not turn into wood decay fungi over time.

Moisture In Your Attic
Its common to find mold in attics, especially where there are poor ventilation and high humidity conditions. Few people spend time in their attics, particularly in todays homes that use roof trusses instead of rafters and storage space is impractical.
Most people never enter their attic unless theres an emergency. Thats usually due to a water leak, and by then, a mold infestation may be well advanced. Running water is easy to identify in an attic as its going to pour through hatch openings or from light fixtures. High humidity and moisture levels are more difficult to find. Consider these attic moisture sources:
Leaky or missing roof shingles
Leaking drain, waste and ventilation pipes
Condensation on plumbing pipes
Improperly installed flashings and ridge capping
Improperly installed exhaust vents for dryers, bath and kitchen vents
Condensation during cold months
Heat causing high humidity in warm months
Faulty or missing insulation
Snow and ice damming problems
Heaters or furnaces in attic
Air conditioning units in the attic
Stored materials that are wet or damp
What Are Mold And Mildew
Mold is not a plant or an animal. Mold is a microscopic organism thats part of the fungi kingdom. It occurs in every warm part of the world where theres a moist environment. The exact number of different mold species is unknown, but scientists estimate that over 100,000 different types of mold microorganisms exist. Statistics from the Center for Disease Control in Atlanta report that at least 1,000 species of mold are common in the United States.
Mold is a natural part of all environments where other oxygen-dependent organisms thrive. Youre exposed to mold every day. Outdoors, mold plays an important role in breaking down cellular matter and allowing it to decay as part of the decomposition process. Soil enrichment wouldnt occur without mold. Typically, fallen trees and dead leaves turn moldy within days, especially where light is limited and air is plentiful.
Indoors, mold acts much the same way. According to the United States Environmental Protection Agency in their informative publication A Brief Guide to Mold, Moisture and Your Home, mold can take hold within 24 to 48 hours after a warm enclosed area like a bathroom wall becomes wet. It can colonize within a week and spread immediately.
Its the causes of mold that are most important to know to prevent it from taking hold.

Mold And Mildew Can Make You Sick Too
Besides damaging your house, mold can cause severe health problems. One consultant we interviewed confessed he crawls around in moldy places day after day, month in and month out, and never suffers ill effects. Otherssome estimate about 10 percent of the populationare severely allergic to mold. Its primarily the dinky reproductive spores that people react to. Twenty of them sitting side by side could fit across the period at the end of this sentence. That means theyre hard to filter out. The spores also have an incredible hang time theyre able to stay suspended in midair for hours on end. That means theyre easily inhaled.
Tightly sealed newer houses may be better at holding in heat, but theyre also more likely to trap moisture and spores. Mechanical ventilation, like an air-to-air heat exchanger, is critical for healthy air quality in tightly sealed new homes.
In truth, most of us fall somewhere between the two extremes of invincibility and super-sensitivity. But even normal folks will react to unusually high concentrations of mold and spores. And the time youre most likely to stir up spores and inhale and ingest them is the very time youre trying to get rid of the stuff. Thats when you need to be the most careful.
