Looking For Signs Of Mold In Your Home

Mold can occur anywhere it finds a damp location where it can feed upon the organic components in your building materials. When looking for mold in your home, its important to keep an eye out as well as a nose out for possible signs. Often times mold can hide behind furniture or appliances, making it more likely for you to smell the mold than see it for the first time.

Black mold will have a strong earthy, dirty, and musty smell and is the laymans term used for Stachybotrys mold. This type of mold can have a particularly strong smell making it more noticeable when starting to form. Unfortunately, mold only needs water, organic matter, a dark environment, and time to grow, meaning its often found in places that arent heavily trafficked in the home.

Dont Leave Wet Stuff Laying Around

Anyone who has young children knows how much water ends up on the floor during bathtime. Its safe to assume that the bathmat is soaked, and you may have a couple of wet towels leftover too. Dont leave these lying around! As soon as youre done using them, get them off the floor and hang them on a towel rack or over the shower rod to dry.

If you have older children, regularly check their rooms for wet towels and clothing. Even something as simple as a sweaty soccer jersey can grow mold if its left to its own devices. Although it may not seem like its worth the argument that ensues every time you ask your teenager to pick up their room, we promise its worth it in the long run.

Check For Colored Spots

One of the easiest ways to figure out if theres mold in your attic is to look for colored spots throughout the area.

It also helps that mold commonly possesses colors that stand out from its surroundings, such as pink, yellow, orange, or white. These are all different species of mold that, while not immediately harmful, can cause complications over time.

Other colors to watch out for are gray and black. These are typically more harmful than other types of mold and tend to spread quickly throughout the attic.

Greenish black, however, is more of a concern. This is the color of the infamous black mold you often hear about being a problem in homes.

Prolonged exposure to black mold can lead to severe health problems, such as lung complications and memory loss.

Question: Interpreting Mold Levels When I Don’t See The Mold Indoors

How to search for hidden mold in your home

John said:

I am buying a Condo and Elevated mold levels have been detected by inspectors in two air tests. 2 Inspectors found No signs of visual mold, or any water in walls , nothing under sinks, etc. There was a leak in to the bath ceiling 5 years ago and it was “caught and repaired immediately”. AC is new — only 1 year old but has some mold growing in 3 places. Seller wants to clean the AC system and ducts, do 2 days of air scrubbing and then do an immediate air test to see if the problem is fixed.

I am having the Bath ceiling inspected by having holes drilled and scoped and if needed cutting 6″x6″ area.

Question — without major construction — just AC and duct remediation and air scrubbing, do we need 24 hours after the air scrubbing — or can the air test be done immediately? Will and immediate test pick up another source of mold if it exists — or do we need to ewait 24 hours after air scrub?



Not much of this sounds sensible to me.

If a severe mold problem was found and repaired five years ago you would not be detecting high levels of indoor Penicillium sp. spores today.

I suspect the problem was never found, OR there have been other leaks and there are other mold reservoirs that need to be found and removed. This case illustrates why mold “tests” alone, without a competent inspection are not so helpful. We just have to visit the investigation de novo, this time, finding where the problem resides.

Growth Spots Of Varying Colors

Black mold, as the name implies, is often dark in color. When searching for black mold, look for circular-shaped spots that are black, dark green or dark brown. Some black mold can also take on shades of orange or have flecks of white within it.

Most of the time, black mold has a slightly furry appearance. Larger growths of mold may appear as a black stain that stretches along your wall, floor or ceiling.

Where To Look For Hidden Mold On And Under Carpeting And Flooring

Lift carpets to inspect carpet tack strips and carpet padding and carpet underside.

Water stains on carpet tack strips and rusty carpet tacks on those strips are other indicators of the leak history in the area.

Remember that mold may be present on the under-side of the carpet itself or on the top or under-side of carpet padding located below the actual carpeting. Hidden mold may be found on the floor surface below the carpeting, or even between layers of finish flooring and subflooring.

We also find mold quite often on the under-side of subflooring. Look up at subfloors from basements or crawl spaces where a wooden subfloor is installed on furring or “sleepers” placed over a concrete slab, it may be necessary to cut small test openings to explore these hidden cavities.

The best place for a test cut to look for mold over an inaccessible floor or any other building cavity would be where we suspect that water has been most likely to be present, but openings may also be made in unobtrusive spots nearby, such as in a closet or under shelving where the cosmetic damage will be minimized.

Water can also pool up around sinks, bathtubs, dishwashers, or washing machines, so be wary and clean any water up right away. Some problems to look out for outdoors include a yard that slopes toward the foundation of the house, leaky shingles on the roof, and improper caulking on windows.
