Alphabetize to Photographs of & Notes on Mold Growing on Edifice Surfaces and Materials

Links listed below provide photographs of mold that we have photographed, sampled, and tested on a wide range of surfaces and substances establish on building surfaces or on items and contents found in buildings.

The very moldy walls, ceiling and mantle in our photograph at left were observed in the home that inspired this mold-in-situ article. The home had suffered a burst heating piping and remained wet for months. At our investigation at that place was mold growing on only about everything in the edifice including the building itself and all of its contents.

In fact it was more interesting to observe the few surfaces where there was no apparent mold growth.

Having the reward of our own aerobiology lab and several rolls of adhesive record, we collected many samples in this edifice in order to brainstorm to acquire what fungal genera/species adopt just what surfaces and materials commonly establish in residential buildings.

CONTACT us to submit photographs of mold growth on other man-fabricated or edifice-related materials.

Photographs of mold found on the surface of items, materials, & surfaces institute indoors

Mold on/in Air Ducts & in Air Handlers in HVAC systems

These photographs, courtesy of Florida home inspector and by ASHI President Mark Cramer illustrates mold growth in HVAC ducts and in or on an air conditioner air handler.

The most common particles establish in the dust and debris in air ducts are fabric fibers and skin cells.

Dust mite fecals and insect fragments are allergens found there more ofttimes than mold. When we exercise identify mold in air workout or heating ducts information technology is about often establish where h2o aerosol were sprayed into the ductwork from a blower unit of measurement or where there were h2o leaks into or condensate in duct system.

The most common mold genera we detect in this location is Cladosporium sp.

Mold on Fiberglass Air Ducts

Below: Photographs provided by an InspectApedia reader and by our own microscopy lab include a photo of white or light gray mold growth on the interior surface of a fiberglass-lined air duct and a second photograph of Pen/Asp spore chains constitute in this sample.

A study of this mold plant Cladosporium sp., Aspergillus sp. and Penicillium sp. in heavy growth in the ductwork. Details of this air duct mold contamination study are found at FIBERGLASS AIR DUCT MOLD Exam

Also see more photos at MOLD on/in FLEX DUCT [photos]

Information almost moldy air handlers and ductwork is

at AIRBORNE PARTICLE & MOLD LEVELS in DUCTWORK
and

at BLOWER LEAKS, RUST & MOLD

Mold in Air Handlers & Fan Blower Units of Air Conditioners & Furnaces

You volition notation that mold growth is present on the air handler insulation, on the metal surfaces of the blower associates, on refrigerant and condensate piping, and even on the paper labeling on the blower cage.

When mold growth is on unpainted metal in an air handler it is most probable dining on organic dust and debris institute on those surfaces.

Below we illustrate a dirty, mold-contaminated air conditioner blower squirrel cage fan.

And just beneath we testify what amounts to a small amount of mold contagion on and in the fiberglass insulation of a New York air conditioning system'due south blower unit.

Beneath is our lab photo of mold collected from the air handler shown at in a higher place correct - identifying this mucus as Cladosporium sp.

Important information nigh moldy air handlers and ductwork is at BLOWER LEAKS, RUST & MOLD.

Mold on Aluminum surfaces such equally edifice siding

This photograph illustrates mold growth on aluminum siding and trim.

Mold on Appliances, refrigerators, etc

This photograph pair illustrates mold growth on a kitchen range fan hood (below left) and a refrigerator door surface (below right).

Beneath our pictures show mold growth on plastic controls for a kitchen stove and on the oven door handle, also a plastic component. This home had been subject area to flooding that was undiscovered for weeks or longer.

Mold on refrigerator and freezer door gaskets is common, is not probable to be a wellness concern in a building, should exist handled by normal household cleaning, and is non illustrated hither.

Mold on Art Works, paintings, painting substrates, other artworks or cultural artifacts

We assist museums & curators with mold diagnsosis, cure, & prevention on works of art.

Details and more illustrations of paintings or other artworks being examined for mold contamination are at MOLD on ART WORKS, TESTING FOR

At MOLD RESISTANT CONSTRUCTION we talk over methods to reduce the chance of mold growth not only on building surfaces but on and in the contents found in buildings, including works of artifacts and works of fine art such equally paintings.

At  ART CONSERVATION - Cultural Heritage and Aerobiology we draw a text that offers some help in controlling mold and other sources of damage to paintings as well as other cultural artifacts.

Mold on Asbestos Pipe Insulation

Our photo at right and our ii moldy asbestos pipe insulation pictures below all prove black and greyness mold colonies as smaller "spots" growing on the painted surface of cloth covering asbestos pipe insulation.

Mold on/in Attics and attic surfaces (roof capsule)

The photographs below illustrate mold growth on plywood roof sheathing. At left is prove of a serious roof leak or attic moisture condensation problem (black plywood) and at right a much smaller brown mold growth on the plywood roof sheathing of a newer home.

We may find mold growth similar that shown at correct just above a bathroom ceiling fan that vents directly into the attic space. These molds are very often Aureobasidium pullulans, C. cladosporoides, C. sphaerospermum, or Cladosporium sp. though other dark or dark-brown molds (such equally Taeoniella sp.) may be present too. Remember, mold identification by naked eye is unreliable; lab sample assay is usually necessary.

The photographs below illustrate mold growth on tongue and groove roof sheathing in an attic. These molds are frequently Aspergillus sp. or Penicillium sp.

Mold on/in Cranium Stairs

This photograph illustrates trivial, hard to spot mold growth on a pull-down attic stair.

We too have found mold growth concentrated on an attic flooring effectually the attic stair entry opening.

Nosotros suspect that extra air movement leaking into the attic from beneath deposited actress wet at that place, inviting mold growty.

Mold on/in Automobiles, boats, cars, RVs

This photo illustrates auto flooring carpeting padding and audio insulation that smelled moldy even though mold was not easily visible to the naked eye. Leaks from the windshield pillars had soaked the motorcar's carpet and carpet padding.

Extreme car mold contamination of most of the surfaces inside of the vechile is illustrated by our photo beneath

This photograph of car mold illustrates an extremely-serious case of machine mold contamination - encounter Auto MOLD Contagion for details.

Mold on Barn Framing, new construction

This photograph illustrates mold growth on framing lumber used in structure of a new barn.

The growth design and color and localization of the black mold to only private framing members even though they were touching to form a built-upwards beam was compelling evidence that this mold was present on the lumber at the time of delivery - it was not growing in the structure.

Most likely this is a cosmetic mold such as Ceratocystis/Ophistoma -

encounter BLACK COSMETIC MOLD for details.

Reader Q&A - also see the FAQs series linked-to below

Certainly,

Especially if some molds are got into a cut or open up sore on the skin or worse, into an eye or other sensitive body area the result can exist a fungal infection.

Tara, only let's avoid the fault of thinking we only intendance about "black mold" - of the 200 or and so most-mutual harmful indoor molds institute in buildings, some are night coloured but many are white, gray, green, red, yellowish, brown.

Getting some genera/species of mold into a sensitive body area including an open cut or sore or even an eye can cause a fungal infection.

If you accept that business organization see your medico: don't try to diagnose and treat with online informants. Nobody tin can brand a safe accurate guess from text or even photos.

Can blackness mold effect soneones peel?

Indeed that looks like a mucus growing by and large in the white paint of the RV logo. Identifhing the mold generas/species cannot be done from a photo, and in fact doesn't matter in that knowing the mold'due south name (east.1000. Cladosporium sphaerospermum) won't alter what'due south needed to be washed ane bit.

Try scrubbing with a gentle plastic scrubby sponge and dish detergent; if stains remain, I've had success using a spray-cleaner that includes bleach, but

Lookout man out: to rinse thoroughly and quickly then every bit to avoid bleached streaks downwardly the siding surface. Test first on an unobtrusive area.

Can someone delight identify this substance? Mold maybe? Covering the front end of an RV? Information technology'southward only on the front on aluminum and fiberglass. Every bit a detailer I've never seen annihilation quite this bad! How to tackle it is the help I need. Thanks

Eso

The photograph is a bit blurry then I'm not certain but that looks as if information technology could exist some mold growing inside your metal ductwork.

Various species of mold will grow on the organic component of grit and debris that is deposited on the interior of h v a c ducts

I attached an image but for some reason it doesnt appear in my post

Tin anyone verify if this greenish brown stuff at the lesser of my ducts is mold?

Nib

That could indeed be a white fungus or "mold" growth on roof sheathing.

Though I have to say it looks a lot similar white paint blots.

There are some adjacent nighttime areas that could hiint at moisture and mold in an attic. From a sharper photo more-close-upwards one might be sure if information technology'southward paint or not;

Is it mold? Diagnostic tip: if at that place are mold-growth-conducive weather in your attic, where you encounter heavy mold growth on plywood roof capsule y'all are likely to come across at to the lowest degree some mold growth continue up onto rafters or other framing, peculiarly where the rafters bear upon the "mold-suspect" white stuff on the plywood.

If it'southward paint it probably won't smear off on a paper towel or gloved finger.

Bluntly nobody who actually knows mycology and mold would, from looking at the white growth on a surface past naked middle, assert that it is a species of Aspergillus. Therefore nosotros already know something about your third remediator. Aspergillus might be white but it can exist any of many other colors, and there are enough of other white molds that are not Aspergillus.

WHITE MOLD PHOTOS inspectapedia.com/mold/White_Mold_Pictures.php offers some details - a spot where I'll re-re-create our give-and-take here every bit you lot have such a dainty white mold photo.

Aspergillus occurs as virtually 180 unlike sub-species (some sources list 250 species) of which about 20 are usually establish on building surfaces. ( Usa CDC world wide web.cdc.gov/fungal/diseases/aspergillosis/causes.html )

The colour of Aspergillus mold colonies ranges from black or very dark brown (A. niger) through greens, yellows, tans; A brand new Aspergillus colony may announced every bit a white growth just normally when we meet species of Aspergillus on a building surface it's not brand new (hours to days sometime) and information technology's got color.

As the Aspergillus colony matures it darkens to green, green-gray, or greenish-brown with a white apron at the margin, very much depending on the species of Aspergillus and possibly also every bit on what the Aspergillus has to eat - what material information technology'southward growing upon.

Furthermore it's unusual for there to be just i mold genera/species in a building where mold contamination is found. For example I can identify 3 entirely different mold genera/species on the same piece of drywall simply by collecting samples at different heights from a wet floor. That's because the moisture gradient varies, with drywall higher from the floor being less wet and thus growing different genera/species. That's also why any unmarried surface test or virtually other samples exercise not characterize the building's mold family.

Fortunately, despite a near-overwhelming attending given by mold remediation companies and their websites to mold color and what it means, or to scaring the devil of people with a mis-placed attention to "toxic black mold" (as mold may be harmful across the entire rainbow of colors), the colour of the mold doesn't mean a darn thing about what you need to exercise about it. That is, the color of mold does non affect the mold remediation plan.

Remove the mold, clean the surfaces, ready its crusade.

There are occasionally reasons to place the mold genera / species constitute in a edifice, most-often to assistance a doctor'southward work on a sick patient and occasionally to prove that a remediation containment was successful - or not.

Details are at MOLD Exam REASONS inspectapedia.com/mold/Reasons_to_Test_for_Mold.php

More examples of mold often seen in attics are found in our series of commodity on attic mold, including Cranium MOLD, WHAT IT LOOKS LIKE https://inspectapedia.com/mold/Attic_Mold_Identification.php

Any thoughts on what this might be? In cranium. two out of 3 remediators said it was not mold. The tertiary said immediately that it was an Aspergillus. I have not sent for testing yet.
