How to Estimate the Cost of Mold Removal

How to Estimate the Cost of Mold Removal?

Once you see mold contamination in your house, you need to take an action immediately to prevent it from spreading to the rest of your house. Mold remediation requires a specialist who has experience in conducting an initial inspection, isolation, mold removal, and final inspection to ensure that your home is mold-free. With a sheer number of companies offering mold remediation services, it gets quite overwhelming for homeowners to find the best. 

Average Mold Removal Cost

Whichever company you pick, make sure that you get a quote before hiring them. The average cost of home remediation can be anywhere between $1,373 and $3,325. Though, it can go up to $15,000 for a high-end project. That means you might pay $28.33 per square foot. The total cost, however, depends on a number of factors, like the size of the area infested, whether the furniture is involved, the presence of mold in the air, and the type of mold. 

For instance, black mold requires an in-depth cleaning. It involves toxic fungus that can cause chronic respiratory, illnesses, coughing, sneezing, and other health issues. They are found in damp buildings, mostly commercial properties, or isolated residential buildings with water damage. Black mold removal cost depends on the level of infestation. It can be $400 to $3000 (higher for the areas with deep infestation).

Cost Breakdown of Mold Remediation

The cost of mold remediation doesn’t always cross $1500 unless you have a serious infestation with furniture, ceilings, and all corners affected. Smaller project costs around $500, in most cases. Let’s check out the factors affecting the mold remediation cost:

Size of the area

As mentioned before, small areas like the bathroom or small infestation in your living room will cost only a few hundred bucks. The project will cost less than $100 if the infested area is 10 square feet or less. In fact, people clean it themselves. If it’s the entire attic or basement covered with the fungi, expect to pay $3,000 to $5,000. The larger the area, the more workers will be needed, and the higher the cost will go. It’s one of the many reasons why you should consider mold remediation as soon as you notice a problem. 


Location matters as much as the size. For example, if your air conditioning or heaters are infested, the cost might go beyond $5000. It’s best to discuss the HVAC mold removal cost with the mold remediation company before going ahead. If it’s found on the drywall, chances are the specialists will recommend you remove the drywall completely, which can cost up to $20,000.

Materials Involved

Like insulation, if furniture and upholstery are involved, they will need cleaning and replacement. This will be an additional expense for homeowners. If the infestation is significant, involving your whole house, the cost of mold remediation will be $10,000 to $30,000 (including the cost of removing and replacing the damaged items). The additional expense can mount up quickly. The mold removal company can’t give you an estimate of the total cost if a large area, with your home appliances, drywall, furniture, and other accessories are infested. You need to talk to a renovation company for an estimate. 

Type of Mold

Mold growing on the surface of your building looks dangerous as it spread rapidly. However, these are easy to remove with regular cleaning detergents. Most people consider a DIY job for this type of mold. The problem is with the mold that penetrates the drywall, your carpet, walls, ceilings, and other corners. 

Not only are they hard to detect, but they cause significant damage to your surface. You may need to remove and replace the damaged materials altogether. Besides that, certain types of mold require high-grade cleaning tools, qualified and insured technicians, and full house ventilation after remediation. Aspergillus, While Mold, Green Mold, Fusarium, and Black Mold are the most common types found in residential properties. Their removal can cost $1000-$5000. 


Not all mold removal companies charge the same price. The cost of labor depends on the experience, qualifications, and training of the technicians, as well as, the time it takes to remediate your house.

How to Get an Accurate and Free Mold Removal Estimate?

You should get a quote from the mold removal company before assigning them a date for the initial inspection. Any professional will conduct a free mold assessment in your house to identify the areas infested so they can quote the total cost accordingly. They include the cost of equipment, labor, lab costs (for detecting molds in the air), and other expenses. Make sure you ask them about any hidden fees. 

Before you call the company for a quote, use the mold remediation cost calculator and get the estimated price of the mold remediation services in your area. These calculators can filter the search list by your zip code. Besides, they show you the cost breakdown, so you can get a clear picture of the services you are paying for. 

When Do You Need Mold Remediation?

Mold grows in dark and damp places, which is why they are hard to detect early on. Especially, in places like the attic and basement. The biggest mistake of a homeowner is trying to fix the mold with DIY techniques. Although you can get rid of the surface molds, you don’t know if it has penetrated the ground or your walls. Mold has a musty and earthy smell. 

If you notice green, black, white, or any kind of fungi in any corner of your house, call a mold remediation company immediately for assessment. The sooner you call help, the better. Not only for your property but mold remediation in the initial stage will prevent health risks significantly.
