Common Places Where You’ll Notice Mold Odors

Mold thrives in moisture.

The most likely places you will detect the dirty damp smell of mold are:

  • Bathrooms- The area under the sink, around the bathtubs and inside the showers.
  • Basements – Basements are number one because they lack proper ventilation and are usually moist.
  • Kitchens – Under appliances, sinks, leaky pipes.* Closets – Closets should not be wet. Damp clothes and shoes can grow mold fast.
  • Attics – Roof leaks can cause mold that you can smell before you see it.
  • Washing machines and dryers – Laundry rooms can be a moisture trap.

When you smell that sharp musty smell in one of these places, investigate.

How to tell Mold odor at Home

Many times you dont know whether the smell is actually mold or mere dampness. Some of the easy checks are:

1. Sniff Test

Go out to get some fresh air and then move around various parts in your house. When one part of your house has an unpleasant odor and is musty and the others are not, it could be indicating there is mold present.

2. Check Fabrics and Carpets

Clothes, curtains, and rugs are some of the things that absorb the mold odor within a short time. As long as they smell musty, it is probable that mold is growing in the vicinity.

3. Look for Visible Signs

You’ll smell it before you see the mold but still inspect walls, ceilings, tiles and nooks looking for spots, stains or discoloration.

4. Check Health Symptoms

Some people sneeze or cough, get headaches or watery eyes because of mold smell. A clue is when your symptoms increase when you’re in some rooms.

5. See if Odor Gets Stronger When It’s Wet

When you turn on the heat, it rains or the humidity is increased, the mold smell may get stronger.

Mold Smell vs Other Smells

Sometimes we end up identifying mold smell with others. Here’s how to distinguish them:

  • Dusty smell – dusty air has a dry and earthy aroma but not moist or stale.
  • Foul smell of rotten food – more intense and clear than mold smell.
  • Pet smell – usually attached to hair, stains or visible dust.
  • Smoke smell – quite different; mold is clammy and musty, smoke is dry and burned.

Knowing the smell of mold will help you not to confuse it with others.

What Makes Mold Smell Musty

The musty smell is caused by the chemicals mold emits as it grows and eats whatever it finds such as wood, paper or clothes. Mold only lives on wetness so when there’s an odor, there’s definitely water problem somewhere in the house.

It might be the result of a leak or improper airflow or an excess of moisture. Without addressing the odor, the mold will continuously expand, the longer it spreads the more damage it will cause.

Mold Odor Hazards

An odor is bad, but the bigger picture is the consequences of that odor. Mold causes:

  • Allergies (sneezing, runny nose, itchy eyes)
  • Asthma attacks
  • Headaches
  • Fatigue
  • Skin irritation

The elderly, children and those with low immunity are more sensitive to mold odor and spores.

Safe DIY Method to Reduce Mold Odor

Who knows by the time you call an expert you can already reduce the smell a bit yourself:

  1. Switch on the fans and open the windows and doors.
  2. Always make use of an air dehumidifier to help in lowering of moisture.
  3. Whatever surfaces it is use vinegar or baking soda to wipe them off.
  4. Make sure that fabrics such as curtains, rugs and other clothing materials are kept clean and dry.
  5. Check sink leaks, roofs or walls.

These steps can help with the odor but can do nothing to eliminate the underlying issue if mold is present inside walls or ceiling.

Why Professional Remediation Should be Prioritized

After all it’s just the smell itself that’s a symptom of something bigger. Although DIY tricks can hide the odor, they can’t combat it. Mold can be hidden in walls, floors, under or in insulation and are not exactly reachable.

That’s why hiring a mold cleanup service is always the better option. Professionals can:

  • Find the root cause of the mold.
  • Eliminate mold in a safe manner without spreading spores.
  • Eliminate the moisture issue to prevent a recurring problem.
  • Protect your health, body and property.
