Mold Remediation Cost Factors 

These are the main cost factors that will affect the cost of mold remediation in your home in Phoenix, Arizona. 

Mold Location

5 common places to find mold illustrated, including attic, walls, and bathroom

In desert areas like Phoenix, the Monsoon season can cause flooding, and plumbing issues like malfunctioning appliances or a leaky pipe—especially when the source is hidden behind walls—can cause extensive damage before issues are detected.

It costs more to remove mold from certain areas of your home than others. For instance, mold growth in hard-to-reach areas, like in your HVAC system or drywall, can require more time and materials to remove than mold in very accessible areas, driving up costs.

LocationAverage Remediation Cost
Attic$750–$3,000
Basement$375–$2,250
Crawl space$375–$1,500
Wall$750–$15,000
HVAC systems$2,250–$7,500
Bathroom$375–$750
Whole house$7,500–$22,500

Mold Infestation Size

Most mold removal professionals charge $10 to $25 per square foot. So, if you're removing mold from a 100-square-foot area, you can expect to pay around $1,000 to $2,500. But factors like where the growth is and the mold type can affect how much it costs to remove it. 

Mold Inspections and Tests

Mold inspection costs between $300 and $1,075. Mold testing is key to determining whether you have the presence of mold in your home, plus the extent of the infestation. You’ll need to hire a mold inspector to test surface samples in your home before moving forward with remediation.

Mold Type

Regardless of how it affects remediation costs, you need to know which type of mold you have in your home for your safety. In Phoenix, the most common mold types include Cladosporium, Penicillium, Aspergillus, and Stachybotrys (black mold). If a mold test reveals the presence of black mold, your mold remediation pro will likely charge more to remove it based on the additional cost of protective equipment. 

Type of MoldDescription
AlternariaA common mold found outside in spring and summer, it primarily attacks plants.
AspergillusWhite fuzz that turns black over time, but it can also be brown, yellow, and green. It can cause respiratory illness and requires immediate remediation.
AureobasidiumGrows on painted surfaces and behind wallpaper. It’s often pink and causes allergies.
ChaetomiumExtremely toxic and can cause brain infections and various cancers. A white fuzz that turns to blue or green. Requires immediate professional removal.
CladosporiumCommonly found in basements and HVAC systems. It can cause mild allergy symptoms.
FusariumOne of the most toxic molds; requires professional removal once discovered. Often caused by water leaks, it is commonly found in walls and floors.
PenicilliumBlue-green and grows in areas of elevated moisture where water damage has occurred. It can be very dangerous.
Serpula lacrymansCauses severe damage to wood and spreads fast. Unfortunately, this mold is usually found after it has spread widely.
Stachybotrys chartarum (black mold)Extremely dangerous, not to mention fast-spreading. Requires immediate removal by a professional.
TrichodermaGrows rapidly in wood, plants, and soil. Commonly found in HVAC systems and not as widely discovered as others in this list.
UlocladiumA dark-colored mold found near windows and in kitchens and basements. Looks like black mold, but it isn’t as toxic to humans. Nevertheless, it still requires removal.

Damage Caused by Mold

If left untreated, mold can damage your drywall, carpeting, and flooring. Replacing or repairing your walls or floors will add costs to the removal.

Here are some cost estimates for different types of mold damage repairs in Phoenix, Arizona:

Repair TypeAverage Cost
Drywall$750–$2175
Carpet$580–$1,950
Flooring$150–$400

Mold Remediation Pro Costs

If the area of the mold is larger than 10 square feet and there’s extensive water damage, the Environmental Protection Agency (EPA) recommends hiring a pro to remove it.

Mold inspections cost $300 to $1,025 and are the first step of the remediation process. You’ll find out if you have mold, the types of mold, and the severity of the issue.

Labor costs for hiring a mold remediation company in Phoenix, Arizona, range from $75 to $120 per hour, depending on the types of mold, how accessible they are, and the extent of the damage.

Certifications

Certifications aren’t required for contractors to work as mold remediators in Phoenix. However, it is advisable to look for remediators with a certification from various organizations, including the National Environmental Training Institute (NETI), the Professional Mold Inspection Institute (PMII), or the Institute of Inspection, Cleaning, and Restoration Certification (IICRC). 

Permits

Mold remediation in Phoenix doesn’t require any permits. But if the project involves intensive repairs or construction, your contractor will need to secure building, electrical, plumbing, or mechanical permits. Common examples include a building permit for removing moldy insulation and sheetrock or a mechanical permit for installing a replacement HVAC system or ducts.

Additional Pros to Consider Hiring

Each mold remediation company is different, so check and see if they offer rebuilding and repairs in addition to testing and remediation. If they only complete testing and remediation, you’ll need to hire additional pros to finish the project.

For example, if your wall has extensive damage, you can hire additional pros to handle framing, insulation, and drywall installation. Other common scenarios include crawl space encapsulation and foundation sealing to prevent mold growth or plumbing and roof repairs to fix leaks. 

Here are some additional pros you may need to hire:

  • Framer: $7–$16 per square foot

  • Drywall installer: $1.50–$3 per square foot

  • Painter: $1–$2 per square foot

  • Insulation installer: $0.40–$6.75 per square foot

  • HVAC installer: $5,000–$12,500

  • Flooring installer: $3–$13 per square foot

  • Subfloor installer: $3–$10 per square foot

Does Mold Remediation Increase Home Value?

If you discover mold in your Phoenix home, getting the problem remediated is essential to a healthy living environment. While mold remediation doesn’t increase home value, it does help maintain it. However, remediation is not always effective, and mold can negatively affect a home’s value. Considering that home value can drop from 20% to 37% if there’s a mold issue when you sell your home, mold remediation could help you protect your investment in your home.
