Mold Removal Cost

the cost to remove mold and toxic materials is $10 to $25 per square foot.

The average cost for mold remediation is $2,242. Typical budgets range between $1,108 and $3,391 or $10 to $25 per square foot. While large mold remediation should be handled by a professional, small removal projects (under 10 square feet) can be done as a DIY project, and cost as little as $10 to $50. Larger jobs may cost upwards of $6,000.

Several factors impact the budget for removal. The amount of growth and level of corrosion may require replacement of structural materials. Many remediation projects also require specialized protective and disposal equipment.

Fungi in the home can cause extensive property damage. They also pose a wide range of health risks. The problem only grows over time. Remediation can be expensive but is best handled sooner rather than later. Working with a licensed and experienced pro is the best choice for a comprehensive fix.

Average Cost of Mold Remediation Per Square Foot

Most experts charge between $10 and $25 per square foot for mold mitigation. For a 100 square-foot area, which brings your budget to $1,000 to $2,500. The location of the growth will impact the total cost.

Attic Mold Removal Costs

Removing spores in your attic typically ranges between $1,000 and $4,000. The attic is a common growth area because of potential roof leaks. If it is easy to access, expect a lower quote.

If the leak is large or has existed without detection for a long time, you can pay as much as $7,000 for remediation. Roof repair costs between $350 and $1,250 and takes care of the underlying problem. Replacing affected or damaged insulation will incur additional costs.

Basement Mold Abatement Costs

Most professionals charge between $500 and $3,000 for mold removal in your basement. That range goes up if the growth is behind finished walls or wood paneling.

The cost to seal your foundation, between $2,250 and $7,100, can prevent future issues.

Mold in Crawl Space Treatment Estimates

Fungus growth in a crawl space costs between $500 and $2,000 to remove. It is often contained to a small area, which is why it costs less to treat than other areas of your home.

Encapsulating your crawl space costs between $1,500 and $15,000 on top of that price and will help prevent future growth.

Cost to Get Rid of Mold in Drywall or Concrete Walls

Getting rid of the growth on your drywall will range between $1,000 and $20,000. Where you land depends on whether you need a simple treatment or replacement of the entire wall and everything behind it.

If it's been on the wall for too long, the material may no longer be usable. In that case, the price to repair your drywall adds another $300 to $825 to that budget.

Removing growth on wooden walls ranges between $700 and $5,000. For concrete mold, that range can go up to $10,000 or more if replacement is necessary.

HVAC or AC Mold Remediation Cost Calculator

Growth in your heating or ventilation system requires treatment that costs between $3,000 and $10,000. That's because these systems require special cleaning to reliably remove all airborne spores.

Remediation Cost by Ventilation System Type
Radiant Heat$1,500 - $5,000
Furnace & Air Handlers$3,000 - $5,000
Air Conditioners$6,000 - $10,000

Bathroom Mold Mitigation Estimates

Removing mold in your bathroom typically costs between $500 and $1,000. If you find or suspect growth behind your vanity, sink, tub or walls that budget can increase to more than $8,000.

Home Air Ducts

Removing growth from your air ducts costs between $600 and $2,000. Like your HVAC system, it may require special cleaning to avoid leaving spores behind.

Taking early action is key to preventing health problems. Consider paying to clean your air ducts and vents regularly, at a price between $275 and $500.

Whole-House Mold Removal

If toxic spores affect your whole house, expect to pay between $10,000 and $30,000 for the project. That includes both the remediation and the price to repair water damage to prevent future problems. You will need to replace fabrics, carpets, drywall, and more in addition to the abatement and testing, which adds to the total price above.

Black Mold Removal Cost

Rates for black mold remediation range between $1,000 and $4,500. This is the most dangerous type of growth and can lead to serious health risks. You can't just clean toxic black mold. It requires isolation and methodical removal to reduce these risks.

Other types are less expensive to treat. White mold mitigation costs between $500 and $3,000. It is easier to remove because the growth is still in an earlier stage. It typically hasn't spread as much. Other colors, from pink to green, cost about the same.

Mold Repair and Materials Costs

Depending on the damage the growth has caused, you can pay between $2,000 and $20,000 for repairs in addition to the removal. This might include:

These ranges include the cost for the materials themselves as well as professional installation.

DIY vs. Hiring Professional Mold Abatement Service

Homeowners can perform small remediation projects for a minimal cost. If the infestation covers 10 square feet or less in total area, the EPA says that property owners can generally handle the problem themselves.

After getting an inspection, ask the pro testing the mold whether you can remediate the problem yourself. Mold can be hard to find, and toxic. Handle even the smallest projects with care.

Professionals should perform larger jobs that can range upwards of $10,000. Additionally, if growth exists in more than one area of the home, it is best to leave the cleanup work to a professional remediation crew.

DIY Cost of Removing Mold

Taking on a remediation project yourself will range between $50 and $300 in total. That includes renting a wet vacuum to pull moisture from carpet and wood for around $30 per day. You can purchase a wet vac for $80 to $200.

For very small removal projects, you will only need water and detergent. There are also pre-formulated mold remediation solutions at home improvement stores that cost between $10 and $75. You'll also need between $20 and $150 for safety equipment to protect your lungs.

DIY Mold Cleaning Tips

  • Moisture is the key to spore growth. Fix any plumbing leaks or other sources of moisture as early in the process as possible. Dry everything completely.

  • Use a solution of detergent and water (or a pre-mixed mold remediation product) to scrub away spores on hard surfaces.

  • Drywall, carpet and other porous materials are often irreparably damaged once they are moldy. Throw away and replace these materials.

  • Wear gloves and goggles and use a respirator to avoid breathing airborne toxins. An N-95 respirator, available at most hardware stores between $12 and $25, keeps you safe during removal.

  • Remediation is done when all the growth is completely removed. There should be no visible spores or odor. After cleanup, the site or sites should not show signs of moisture accumulation or spores.

Professional Mold Removal Labor Costs

Labor costs make up a large part of the total price of remediation. Qualified removal companies make use of skilled labor and expensive equipment.

A High Efficiency Particulate Air (HEPA) vacuum, for example, is a $10,000 piece of machinery that makes use of special filters and powerful suction to remove spores from materials. Workers operating HEPA vacuums must wear mold-proof suits and face masks and must be specially-trained.

Benefits of Mold Inspection & Removal Pros

Price alone should not be your only consideration. DIY removal may not take care of the underlying problem, and only focuses on the spots you already know about. You might also clean growth in a way that still leaves toxic traces behind.

Hiring an expert costs more but comes with a wide range of benefits:

  • A comprehensive inspection that detects traces of growth throughout the home.

  • A long-term solution that fixes not just the symptoms, but the underlying issue.

  • Expertise and advice in how to avoid future problems.

To ensure these benefits, you have to find the right pro. Browse our directory of mold removal pros to schedule an inspection and start planning the remediation.


Is mold removal expensive?

The removal alone doesn't have to be expensive. You can clean up growth yourself for as little as $50. Comprehensive remediation through an expert costs significantly more, but also makes sure all issues are taken care of.

Think of it as a positive investment for your home and health. Spore growth only gets worse over time. The high initial price means fewer needed repairs down the road. You also get the peace of mind that your air will be free of dangerous toxins.

How much does Servpro mold mitigation cost?

Servpro is one of the largest mitigation companies in the country. It offers inspections, remediation, and restoration for anywhere between $1,500 and $10,000.

What is mold?

Mold is a type of fungus. It grows best in warm, moist environments and survives by digesting decaying organic materials. Because they do not use chlorophyll to produce food, these fungi don't need sunlight to survive.

This fungus is an important part of the environment. Without it, dead plant matter would overrun the entire world.

Why does mold grow in homes?

Mold grows in environments with high moisture levels that also contain any kind of food source. Common food sources in the structure of the home include:

  • drywall

  • window frames

  • carpeted or uncarpeted flooring

  • bathroom tile

  • interior insulation

  • furniture

  • below plumbing areas (under the dishwasher, sinks, and refrigerators with water lines, etc.)

Growth developing in the structural materials of a basement or crawlspace may require special attention.

Moisture sources that can lead to indoor growth include condensation from high humidity or large temperature differences. Roof leaks, flooding, plumbing leaks, or excessive dampness can also be causes.

What health problems are caused by mold mildew?

Exposure to environmental fungi like this one can lead to skin irritation, breathing difficulties, allergic reactions and headaches. The spores can be an irritant, causing a burning sensation to the skin, lungs, nose, throat or eyes.

Some fungi can trigger asthma attacks in people who are allergic. Even non-allergic asthma sufferers may experience worsened symptoms due to exposure. Symptoms of an allergic reaction include sneezing, red eyes, runny nose or the appearance of skin rash.

The EPA reports that repeated exposure to this issue can bring about increased sensitivity to allergies and health problems. That's why it is important to put an end to the issue as soon as you find it.

Molds can also produce mycotoxins, which are toxic substances found either within or on the surface of spores. They can enter a person's system via ingestion, inhalation or skin contact. Aflatoxin B1 is the best-known mycotoxin. It is a potent carcinogen and inhaling it can cause lung cancer. The fungi Aspergillus parasiticus and Aspergillus flavus produce this carcinogen.

How do I know if I have mold in my house?

A professional mold inspection costs between $300 and $1,025. If you suspect indoor growth, this is a necessary first step. It's the only way to test whether the mold is toxic.

Some contractors offer free testing. The most comprehensive tests come from experts who have specific working knowledge of sampling methods and protocols. That includes those recommended by the American Conference of Governmental Industrial Hygienists or the American Industrial Hygiene Association.

Investigations often disturb potential areas of growth. For example, it may be necessary to cut sections of wallpaper to examine drywall or sections of carpet to test floorboards. Either action may release toxic spores into the air.

Inspections should:

  • Come from qualified experts, preferably a certified professional with significant remediation experience.

  • Examine sites of potential growth and look for sources of moisture.

  • Examine indoor air quality for the presence of spores or other irritants.

  • Check for areas of past or current signs within interior walls, floors, ceilings and other common growth areas.
