The humid climate and warm temperatures in Texas help mold flourish. If you’re dealing with a mold problem, it’s better to tackle it sooner rather than later. Mold remediation costs $2,025 in Houston on average, with most homeowners spending between $888 and $3,298. That said, costs could soar past $20,000 for significant damage across the whole home. Here’s how costs break down.
Mold Remediation Cost Factors
Houston, Texas, has a lower cost of living than most other major cities in the United States. This means mold remediation costs are lower than the national average, but the full cost of the project depends on where the mold is located, how easy it is to access, and the extent of the damage.
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–$9,000 |
| Basement | $500–$4,000 |
| Crawl space | $500–$4,000 |
| Wall | $1,000–$10,000 |
| HVAC systems | $1,000–$10,000 |
| Bathroom | $500–$2,000 |
| 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 remediation pro in Houston, Texas, 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 adds around $5 to $23 per square foot to the costs of removal, depending on the material.
Here are some cost estimates for different types of mold damage repairs in Houston, Texas:
| Repair Type | Average Cost |
|---|---|
| Drywall | $500–$2,900 |
| Carpet | $775–$4,000 |
| Flooring | $200–$4,000 |
Mold Remediation Pro Costs
When you hire a mold remediation company in Houston, contractors charge about $9 to $18 per square foot for their labor, but you may need to spring for additional repairs and hire extra contractors.
Depending on the strain and extent of the growth, mold can be hazardous to your health and the structural integrity of your home. Contractors must hold a Mold Assessors and Remediators License from the Texas Department of Licensing and Regulation.
Additional Pros to Consider Hiring
In most cases, contractors are not allowed to conduct both mold assessment and mold remediation on the same project. There are a couple of exceptions, but you’ll most likely need to hire a separate contractor for mold testing. You may also need to hire contractors to make repairs—like to your flooring or drywall—once the mold is fully removed and take measures to prevent future mold growth. Here are some potential pros and their costs:
Mold inspector: $200–$500 per inspection
Crawl space encapsulation costs: $5,000–$15,000
Basement waterproofing contractor costs: $150–200 per hour
Flooring contractor: $6–$20 per square foot
Drywall contractor: $60–$75 per hour
Does Mold Remediation Increase Home Value?
Mold remediation doesn’t increase home value, but it prevents a significant drop in home value. It’s estimated that a mold infestation can decrease the value of your home by 20% to 37%. Beyond that, a study in The Appraisal Journal found that up to 50% of potential buyers will walk away once they find out about a mold problem.
In Texas, sellers have a legal obligation to disclose known mold issues. In other words, it’s important to get mold handled ASAP and take measures to prevent the mold from recurring (if the problem wasn’t caused by one-off water damage).
