How Much Does Mold Remediation Cost?

The growth and spread of mold can present a serious problem in your property. Instances of mold in your building can be seen through an increased occurrence of water leakages, wet surfaces and the sudden onset of a musty smell. If you find that these symptoms are present, it is important to act as soon as possible to protect against further damages such as structure failures. There could also be health risks for occupants if they.

Mold can trigger allergies and even create respiratory problems for those who are sensitive or vulnerable. This can lead to serious health problems. Often, the presence of mold indicates that your building may have issues with moisture accumulation, water damage, humidity or outside exposure. These issues may at times require serious attention and repairs. Cleanup and removal of mold requires a comprehensive approach known as mold remediation.

In this post, we’ll discuss some important things to know with regards to mold remediation in order to prepare you for the associated costs.

What is Mold?

Mold, which is also called mildew, is a general term for various fungi that thrive in wet or moist environments. Mold spores are invisible to the naked eye and exist everywhere. These airborne spores eventually land on surfaces in a room, and when enough colonies have developed, the fungus becomes visible, usually appearing fuzzy and discolored. Black mold can grow almost anywhere, including in carpets, furniture cushions and drywall.

As with other organisms, mold requires a food source to survive. Certain environmental characteristics promote the growth and spread of these fungi:

  • Moist or wet
  • Warm
  • Ventilated
  • Nutritious (presence of nutrients to feed on)
  • Illuminated
  • Acidic

The cost of mold remediation varies depending on the type, location, and size of the area(s) that need to be assessed. Despite its name, mold is not alive – it only grows or exists in different forms as a result of natural microbial activity.

Naturally-occurring substances such as dead plant matter would overrun the world if there were no fungus present; fungi help decompose biological matter. A single piece of unhealthy mold can grow out by 30 feet within a few days and typically ferments in homes where materials like wood are exposed to high levels moisture accumulated from various sources (including cooking). Mold causes allergies with certain sensitivities and should never be taken lightly; while not all molds can cause infections, certain types can trigger dangerous health consequences.

The fungus that can appear on food that’s been left out of the fridge would ordinarily be considered harmless; however, the presence of mold in your residence can be harmful to those who are allergic. Some fungi produce compounds known as mycotoxins that can be hazardous to the health of humans and pets. Throwing away moldy food usually solves that problem, but mildew buildup in a structure requires a thorough approach, especially where the safety and comfort of occupants are concerned.

The best way to control the growth of mold and mildew is to keep your house or office dry by performing routine maintenance on humidifiers and air conditioners. You should also make sure there are no leaks in pipes or fixtures that allow condensation to collect and water deposits can’t form anywhere—especially near an HVAC system because it has been known for wet systems to trigger severe asthma attacks among those who have allergies or sensitivities.

How Do I Know if I Have a Mold Problem?

If there’s enough accumulation of fungus in a certain area, you may notice a musty odor. If there’s an extreme buildup, you may see a black or brown fuzzy substance in certain areas of a building, especially in areas where water accumulates, such as an enclosed shower or under a sink with leaky pipes. In many situations, mold problems are hidden from view. Occupants with known sensitivities may experience certain symptoms, alerting you to the presence of buildup:

  • Nasal or sinus congestion
  • Respiratory issues
  • Coughing or sneezing
  • Sore throat
  • Headache
  • Itchy, irritated eyes
  • Irritated skin

In the case of toxic mold, often referred to as black mold, significant exposure can result in neurological issues or even death.

If you think you have a mold problem, you should hire a professional mold company to make an official assessment. This pro has the knowledge and tools to sample determine the degree of damage and the level of remediation necessary. A mold investigator is usually credentialed and takes various samples to provide a detailed, objective report:

  • Air sampling: The most common method to assess levels of mold, this usually involves comparing mold concentrations in indoor and outdoor air.
  • Surface sampling: Cotton swabs are rubbed on affected surfaces and sent to a lab for testing.
  • Bulk/dust sampling: Removal of contaminated material is tested to identify the source and type of mold.

Most inspections range from $200 to $600, and some visible inspections are even free. A complete inspection involves moving items as well as cutting and removing walls to confirm the extent of damage. A good investigator confirms the mold source and provides guidance on the necessary level of remediation.

What Does Mold Remediation Entail?

One might think of mold remediation as a type of cleanup, but it’s much more than that. You could use a household cleaner containing bleach to clean mildew in your bathroom, but that doesn’t address the root problem.

For a more extensive fungal problem throughout your property, you can expect professional remediation to focus on eliminating mold by removing the source and preventing regrowth or spread, which can occur in as little as 24 to 48 hours if not properly address. Mold remediation is a multistep process that goes beyond merely wiping away mildew with a detergent:

  • Microbial remediation: Involves removal and cleanup of areas and contents impacted by fungal growth
  • Water damage cleanup or repair: Includes determining the source of water damage, such as a leaky pipe or outside exposure, and removing or repairing it
  • Advanced cleaning and drying techniques: Special methods for brushing, sanding or removing microbes
  • HVAC cleaning: Full cleaning of heating, ventilation and air condition systems, including ducts
  • Damp wiping: Cleaning mold from nonporous surfaces and rapid drying
  • Air quality restoration: Includes HEPA treatments and odor control techniques
  • Debris disposal: Discarding debris properly, preventing it from contaminating other areas

Mold removal specialists wear personal protective equipment or PPE in accordance with the size of the affected area and level of contamination.

How Much Does Remediation Cost?

The cost of mold remediation  is dependent on the following factors:

  • The size of the affected area, usually measured in square foot
  • The severity of the damage, impacted by the length of time that the source issue went undetected
  • The degree of affected areas and contents

mold remediation costs

Most owners can expect to spend between $1,500 and $3,150 for a mold remediation job, which breaks down to a cost of $15 to $30 per square foot for a total area of approximately 100 square feet. The national average job is $2,325. Smaller jobs range from $500 to $1,500, while larger jobs can be in the $3,000 to $6,000 range. Given the additional work that may be necessary for restoration, the hourly cost for most pros ranges from $75 to $120 per hour. Most mold remediation projects take from one to five days to complete.

It may be better to analyze remediation costs based on the area that requires restoration. Certain areas of a structure, such as attics, basements and crawlspace, are more susceptible to the moisture conditions that promote the growth and spread of mold. In some cases, remediation includes sealing off of a room or encapsulation to prevent future damage, which can significantly increase the costs:

  • Attics: Common sources include leaky air conditioning units, leaky roofs or insufficient insulation against condensation.
    • Average: $1,500 to $3,500
    • High: $6,000 to $10,000

  • Basements: Damage tends to be due to leaky pipes, underground dampness or high indoor humidity.
    • Average: $500 to $2,500
    • High: $2,500 to $6,000

  • Bathrooms: Mold thrives due to poor ventilation and collection of moisture.
    • Average: $500 to $1,000

  • Crawlspaces: Damage originates from underground dampness, lack of moisture barrier and ambient humidity.
    • Average: $500 to $1,500
    • High: $3,000 to $8,0000

When the entire house is impacted by water damage as in a flood, the cost to remove all resultant mold could run you from $15,000 to $30,000 or more. In this case, prevention of accumulation and spread may also include additional expenses:

  • Window replacement: Over $300
  • Basement drainage overhaul: $200 to $1,000
  • Home site regrading: $300 to $1,000.

Will Property Insurance Cover Remediation?

While many policies don’t provide coverage for mold per se, they often provide protections for certain types of water damage. For example, damage that arises from extinguishing a fire might be covered. If a pipe bursts in your home and you immediately hire a plumber to make repairs, your insurer may cover these costs.

A claim for damage from a small leak that went unaddressed for an extended period of time may be rejected due to negligence on your part. You should also be aware that homeowner’s insurance often doesn’t cover flooding, so you may need to purchase separate flood insurance.

Professional mold remediation is the only way to fully address a serious mold problem in your home. A natural DIY remediation approach may be suitable when the affected area is less than 10 square feet. Larger removals, though, are best addressed by professionals who are experienced, equipped and appropriately outfitted to get the job done thoroughly, quickly and safely, minimizing the time it takes for you to get your home back to its pre-damage state.
