Mold may potentially grow everywhere. However, if the conditions are right, mold can grow and spread quickly. In areas of high moisture or humidity where water damage has occurred, it may be necessary to remove mold from a home. The clean up costs can depend on the area affected by mold growth. Excel Fire And Water Damage Restoration Services specializes in mold remediation and can help with the cost of mold removal. In this article, we will talk about the cost of mold removal by location to help you understand what may affect the final price.

Cost of Mold Removal by Location

  1. Cost Of Mold Removal In Vents: If the ducts are not damaged, the cost of eradicating mold from the vents ranges between $100 and $500. If your vents are damaged, your ducts may also be impacted and should be examined for mold since they are frequently affected simultaneously. If this is the case, you will need to have mold removed from your air ducts and vents. These extra processes will significantly raise the price.
  2. The Underside Of The Roof Deck: One of the most often damaged areas by mold is the underside of the roof deck. This section of the attic is treated independently from the remainder of the attic. Roof leaks are the primary source of mold growth. Scrubbers are typically used to clean the underside of the deck to prevent the spread of spores. Cost of mold removal ranges between $500 and $1,000, depending on the amount of the mold.
  3. Cost Of Mold Removal In Bathroom: Mold removal in your bathroom generally costs between $500 and $1,500. Mold may develop in the shower, bathtub, sink, drains, or even the walls above the shower if your bathroom is not adequately aired or if there has been a leak. The easiest way to get rid of mold is to utilize air scrubbers. If you discover or suspect mold development under your tub, sink, or vanity, the cost of the fix may skyrocket.
  4. Cost Of Mold Removal In Crawl Space: Mold growth in a crawl space may cost anywhere from $500 to $2,000 to eradicate, depending on the size of the crawlspace and the amount of mold present. Crawl spaces, like basements, grow mold for many of the same reasons: moisture and high humidity levels. They generally have better ventilation and a smaller growth area than basements since they are considerably smaller and more confined areas. It is less expensive than removing mold from a basement.
  5. Cost Of Mold Removal In Attic: Mold remediation in the attic can cost anywhere from $500 and $7,000, depending on the size of the area and the ease of access. Mold thrives in attics owing to inadequate ventilation, moisture issues such as a leaking AC unit or leaky room, and condensation caused by improper insulation. If the most afflicted region is within the insulation, it may be necessary to remove it. The labor for removing the insulation will increase the cost. The most crucial stages in mold treatment in the attic are proper cleaning and ventilation.
  6. Cost Of Mold Removal In Drywall: Mold removal from drywall is one of the most expensive forms of cleanup, with prices ranging from $1,000 to $7,000. Where you fall in that range is determined by whether it is a basic treatment or a complete wall replacement. In certain cases, the pipes that are producing the mold problems may need to be repaired. Mold grows within drywall due to sweating or leaky pipes that enable condensation or moisture to build up.
  7. Cost Of Mold Removal In Basement: Cost of mold removal in the basement ranges between $1,500 and $4,000. Basements are prone to moisture, excessive humidity, and leaking pipes, all of which provide ideal circumstances for mold to take hold and thrive. Mold may develop in basement timber, insulation, and drywall as well. The typical basement size is about 1000 square feet, with most mold areas ranging between 100 and 300 square feet. Basement removal includes cleaning the afflicted areas, drying out the space with dehumidifiers, and removing spores using air scrubbers.
  8. Mold Removal On Concrete Block Walls: Mold on concrete block walls is frequently produced by leaky or sweating pipes, which enable moisture and condensation to accumulate. This form of cleanup entails removing any impacted drywall or insulation, cleaning the affected areas, and repairing any leaky or sweating pipes before repairing the walls. This sort of cleanup may be costly, costing up to $4,000 for big regions.
  9. Cost Of Mold Removal In Air Duct: The typical cost of air duct mold remediation is between $2,000 and $6,000. Mold can be discovered in some HVAC systems’ air ducts. If left untreated, it can contaminate the air and create health problems. To eliminate all airborne spores successfully, air duct mold removal necessitates specialized cleaning. This is one of the most costly mold cleanup methods. Due to moisture build-up and condensation that occurs when filters aren’t replaced correctly or the HVAC system isn’t properly vented and maintained, ducts may become a breeding ground for mold. When mold is detected, the HVAC system must be promptly switched off so that the airborne spores do not spread throughout the property.
  10. Overall Cost Of Mold Removal In Your Entire House: If you have mold and harmful spores throughout your home, expect to pay between $10,000 and $30,000 for treatment. This price includes both the cleanup procedure and the expense of repairing water damage. If you want to avoid mold in the future, consider replacing windows, upgrading your basement drainage system, and having the soil surrounding your property regraded. This job necessitates the replacement of walls, carpeting, and other home fixtures, which adds to the overall cost.

Professional Mold Removal Cost

Mold remediation services generally cost between $500 and $7,000, with the majority of customers spending between $1,500 and $3,500. Approximately 60% of the project’s cost is for labor, with the remaining 40% for supplies. This entails sealing and thoroughly cleaning the entire space. Depending on the quantity of mold, what produced it, and the extent of damage, the procedure can take anything from a few hours to many weeks.

Mold remediation is a multi-step procedure that starts once the affected area has been properly dried. Before cleanup can begin, large fans and dehumidifiers are used to dry the space. If the cause of the moisture or leak has not been repaired, this should be done before proceeding with the cleanup. After the area has dried, inspection and testing will commence. Mold testing is not performed by all mold cleanup businesses. Testing is only performed on request if there are health concerns. When receiving quotes, make sure you inquire about this.

Mold spores spread rapidly if disturbed, thus the area being treated is sealed. To eliminate and prevent the transmission of airborne spores, air filtration devices are utilized to block off the space. Physical barriers, such as plastic sheeting and negative air pressure, keep air from flowing between the contaminated region and the surrounding locations. Following that, the air is cleaned using a mix of “air scrubbers” and HEPA vacuums to eliminate any mold particles or spores.

To eliminate mold from hard surfaces, antifungal and antibacterial cleaners are utilized. If possible, furniture, clothing, or toys are removed from the spot for cleaning to ensure that all mold spores are removed. This procedure entails a thorough cleaning with an antifungal or antibacterial cleaner. Fogging equipment eliminates scents from the area as well as the musty aromas left by mold.

The average cost of mold removal is $800 to $1,100, using a two-step treatment method. A sterilizing solution is fogged into the mold-infested area during dry fog mold remediation. The oxygen then forms droplets that fall onto the surfaces of the mold and weigh it down. This method is most effective in removing mold spores from the air, but the surface may still require further cleaning.

You may choose dry ice removal, which is somewhat more expensive but quite effective in killing mold. This method includes blasting dry ice pellets at the mold-containing surface with high-pressure air. This blasts the mold straight off the surface, making it both fast and efficient. The typical cost of dry ice mold eradication is around $1,400 to $1,600.

Finally, any surfaces that are not cleanable should be removed. This includes drywall, carpets, wallpaper, and other surfaces that have been damaged. Following the removal of the old surfaces, new surfaces are placed. Depending on the degree of damage and mold development, this might be as easy as putting up a single sheet of drywall or as complex as tearing down and renovating an entire room. The most essential thing is to remove any damaged surfaces and materials for everyone’s safety.
