Mold Testing: How to Test for Mold for the Home

Mold is everywhere Mold is a type fungus that grows from small spores in the air. It will grow wherever spores land. Mildew is the most prominent type of mold. Mildew can start as tiny, sometimes black, spots but quickly grows into large colonies. This is the easiest way to find out if you have mold. It is the darkened substance that you can see in grout lines on your bathroom walls, outside on deck boards, and painted siding. It can be hard to distinguish a mildewed surface and one that is dirty. Simply rub some household bleach on the affected areas to test for mould. Mildew can be identified when the area becomes lighter in minutes. It may have dirt if it remains darkened.

Mold or dirt?

Although most mold can be easily identified, some hidden growths can cause surfaces to look dirty. Quickly test for mold using a cotton swab dipped in bleach (16 parts water) and then rubbing it on the wall. Mold is most likely if the spot is rapidly clearing or returns after cleaning. Mold test kits are able to detect mold and identify the type of it, but they cannot diagnose the cause or fix it.

To explore the area, use a screwdriver

Mildew doesn’t cause structural damage to your house. Other types of mold can also cause rot. Use a screwdriver or a probe to determine if mold in your home. Mold can take root in wood that becomes soft or crumbly and that rot has likely begun.

Look out for plumbing leaks

You can find mold near pipes, drain lines and plumbing fixtures. Let the water run for a while, then look for any damp spots. This will allow you to determine if water leaks. Water can travel all directions. It can go down, sideways or up if it wicks into absorbent materials such as drywall. The actual leak may be quite far away. Once you find the leak, could you fix it? This light portable can be used for finding problems in cabinets and other hard-to-reach areas. Here are some ways to get rid of black spots in the bathroom.

Look for Outside Leaks

You should first inspect the roof and walls for any leaks to determine if mold growth is occurring. Measure the moldy area to locate the spot on the wall. Attention to wood rotting areas such as vents, roof flashings, windows and decks. Look for ground that slopes towards your house and drains near your wall. It would help if you kept the ground around your home dry. The ground around your house should not be too wet. Moisture can seep through the foundation or slab and cause persistent dampness. Make sure flashing is correctly installed when fixing a leak

Check out the Ductwork

Moldy ceilings below registers and ducts could be caused by poorly insulated ductwork. When warm, humid air passes through ducts that transport cold air through crawl spaces and attics, it forms water. Condensation indicates that the duct is not properly insulated. Water eventually seeps into insulation. Then mold spores, drywall and other microorganisms (which are everywhere) start to grow. In cold weather, the reverse happens. Warm air can escape from any place where moisture forms, including between duct sections and joints that aren’t sealed. Inspect your ductwork to determine if there is any mold.

Try the Mold

The Center for Disease Control does not recommend routine sampling for molds. It is also not recommended that you identify the type of mold, as all existing mold must be removed. It can be expensive and there is no standard for acceptable testing.
