This kind of service requires hiring specialized mold remediation companies, so let’s review the cost factors to be aware of before the pros arrive.
Mold Remediation Cost Factors
Every mold remediation must start with a thorough inspection to identify the location and severity of the problem. After the inspection, you’ll be prepared to budget based on the following cost factors:
Mold Location
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.
| Location | Average Remediation Cost |
|---|---|
| Attic | $1,000–$4,000 |
| Basement | $500–$3,000 |
| Crawl space | $500–$2,000 |
| Wall | $1,000–$20,000 |
| HVAC systems | $3,000–$10,000 |
| Bathroom | $500–$1,000 |
| Whole house | $10,000–$30,000 |
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. That said, 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 Mold | Description |
|---|---|
| Alternaria | A common mold found outside in spring and summer, it primarily attacks plants. |
| Aspergillus | White fuzz that turns black over time, but it can also be brown, yellow, and green. It can cause respiratory illness and requires immediate remediation. |
| Aureobasidium | Grows on painted surfaces and behind wallpaper. It’s often pink and causes allergies. |
| Chaetomium | Extremely toxic and can cause brain infections and various cancers. A white fuzz that turns to blue or green. Requires immediate professional removal. |
| Cladosporium | Commonly found in basements and HVAC systems. It can cause mild allergy symptoms. |
| Fusarium | One of the most toxic molds; requires professional removal once discovered. Often caused by water leaks, it is commonly found in walls and floors. |
| Penicillium | Blue-green and grows in areas of elevated moisture where water damage has occurred. It can be very dangerous. |
| Serpula lacrymans | Causes 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. |
| Trichoderma | Grows rapidly in wood, plants, and soil. Commonly found in HVAC systems and not as widely discovered as others in this list. |
| Ulocladium | A 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 Baltimore:
| Repair Type | Average Cost |
|---|---|
| Drywall | $1,000–$2,900 |
| Carpet | $775–$2,600 |
| Flooring | $200–$550 |
Mold Prevention
After a mold remediation crew handles the removal and cleanup, you’ll need to consider what measures to take to ensure it doesn’t come back. DIY mold prevention steps include:
Drying standing water immediately
Improve kitchen and bathroom ventilation
Use cleaning products that target mold growth
Choose mold-resistant materials
However, some preventative projects require hiring additional pros. For example, you’ll need to hire a local plumber to repair interior and exterior leaks or improve your drainage system, while a local HVAC professional is necessary to replace venting or install a whole-home dehumidifier. Consult your mold remediation pro for recommendations for additional pros.
Mold Remediation Pro Costs
The Environmental Protection Agency (EPA) recommends only removing mold yourself if it covers less than 10 square feet. Otherwise, it's best to call a Baltimore mold removal service. That said, even if the mold looks like it only covers a small area, you should always call a pro to inspect it to ensure there isn't additional mold hiding behind walls or floors.
Look for a contractor with specific certification in mold remediation—a process that includes identification, cleanup, removal of infected materials, and eventually signing off a completed project, which is important for legal purposes.
Additional Pros to Consider Hiring
Once the mold remediation crew is done, you’re likely to be left with several materials to replace, including drywall, carpet, and wood. Some of these repairs may be DIY or handled by the remediation technicians, but others require the help of an expert. Expect to arrange repair work with an experienced contractor to get your home looking its best.
Hire a drywall contractor to replace drywall: $1,000–$3,200
Hire a carpet installer to replace carpet: $3–$11 per square foot
Hire a plumber to fix leaks: $45–$200 per hour
Does Mold Remediation Increase Home Value?
Mold remediation is necessary to remove health hazards in order to sell a home. Resolving mold problems quickly will preserve your home’s value by avoiding major structural damage and other serious issues.
In fact, the resale value of homes that have mold drops by 20% to 37%, due to safety concerns and increased likelihood of plumbing or structural problems. Think of mold remediation as a stepping stone toward preparing a house for sale and an opportunity to start fresh.
