Mold remediation is the process of identifying and removing unhealthy levels of mold that have colonized in a home, office, school or other building. Over time, if untreated, mold can destroy a home by breaking down cellulose-based materials (like wood or ceiling tiles) and causing a slow and messy decay. In the shorter term, a mold infestation can cause severe health problems. According to the Federal Emergency Management Agency (FEMA), mold can trigger respiratory problems, nasal and sinus congestion, eye irritation, nose or throat irritation, skin irritations, problems with your nervous system, and aches and pains. Mold inspection and mold remediation are often requested in tandem, although they are two separate services. Nationally, mold inspection costs range from $250 to $300. If mold has been positively identified in your house, either by visual examination or through mold testing, remediation can safely remove it. Properly trained and equipped professionals use specialized equipment (like vacuums and air scrubbers with HEPA filters) to keep mold spores contained while they remove contaminated materials and treat infested areas with antimicrobial spray. A key component to a successful mold remediation after eliminating the mold is ensuring that the water source that caused the mold infestation is also resolved.
Mold testing can help identify a mold infestation in your home or business. Mold inspection costs can vary based on the type of test you want done and the number of samples you request. The national average mold inspection cost is $250-$300. The EPA explains that if you have a visible mold problem, in most cases sampling and testing is unnecessary. However, if you have unexplained and potential mold-related illness or can smell mold in your house, mold inspection costs may be a good investment. To avoid unscrupulous testers, the EPA recommends working with a testing agency that adheres to the analytical methods laid out by professional organizations such as the American Industrial Hygiene Association or the American Conference of Governmental Industrial Hygienists. Mold inspection costs can vary based on the type of testing done. Prices can also vary, depending on the size of the home, the number of surface areas to be tested, and the extent of the mold infestation. Here are some examples of mold inspection average costs:
- Swab testing: $200-$300
- A professional collects a surface swab from a potentially infested area for testing in a lab. Some professionals have concerns about this being the sole test done because it only gathers a small amount of data from a certain area of the house. That’s why it’s frequently done in conjunction with air cell testing.
- Air cell testing: $250-$350
- A professional collects an air sample in the home to measure the amount of mold spores in the air. This test is frequently done in conjunction with swab testing to ensure more complete data. Costs are higher for this test because the equipment required of the contractor is more expensive.
- Both air cell and swab tests provided by the same company: $400-$600.
Mold remediation can eliminate mold colonies from your home or business. Mold is a normal part of daily life, but in wet or humid settings mold can quickly colonize and spread by making spores. Whether visible or hidden, untreated mold can cause real health problems and cause extensive (and expensive) damage to your property. Mold remediation involves killing the mold, removing the dead mold and preventing future mold growth. Here is an example of the steps involved in professional mold remediation:
- Contain work area and apply negative air pressure HEPA air purifiers to prevent cross-contamination. If spores spread, the colonies can easily regrow elsewhere in your home.
- Mist an EPA-registered antimicrobial to suspend and kill mold spores.
- Remove affected building surfaces.
- Bag and dispose of contaminated materials properly.
- Treat cavities/underlayment and dehumidify.
- Abrasively remove dead loose mold.
- Apply EPA-registered protective sealer.
- Perform clearance testing.
Remove containment materials.
Mold damage may or may not be covered by your homeowner's insurance. Mold damage is caused by standing water and excess moisture. Mold damage can be covered by insurance when an item already covered under your homeowners insurance breaks accidentally — for example, if your plumbing suddenly ruptures and water floods your house, the homeowners insurance will cover part or all of the costs for the plumbing repair and any mold remediation costs necessary as a direct result of the water damage.
But you may not be able to get insurance to pay for your mold remediation costs if the damage is a result of your neglect — for example, if you’ve had a slow leak under your bathroom sink for years and have ignored the issue. If the insurer can determine that the mold damage is a result of your negligence, they likely won’t cover mold remediation costs. Also, most homeowners insurance will usually not cover mold remediation costs after a flood unless you have a special insurance rider covering your home in case of a flood. To help prevent mold damage, always keep humidity levels in your house between 30 percent and 60 percent, clean up water spills and damp areas right away, and ensure you have exhaust fans in your kitchen and bathroom.
The cost to clean up mold in your home or business will vary based on the pervasiveness of the mold infestation, regional labor rates, and the accessibility of the mold sources for remediation. Mold remediation costs will increase anytime demolition is necessary or the crew must access interior areas like HVAC ducts. For example, these two homes have approximately the same size floor plan but a different number of square feet of mold to be treated. The two homes also have varying levels of accessibility to the sites of mold the mold infestation.
- House 1:
- Mold treatment of 15 square feet in an accessible area with a less aggressive type of mold: $3,400 (average).
- Price includes mold inspection costs.
- House 2:
- Mold treatment of 27 square feet inside an HVAC system requiring a higher level of chemicals and processes: $9,500 (average).
- Price includes mold inspection costs.
