Can Mold Damage Lower Your Property Value?

Mold inside your home is never a welcome guest—and for good reason. While this intruder is commonly known as a health and safety hazard, it can also impact your property value.
Whether you’re considering selling your home or simply want to protect your investment, understanding the relationship between mold and property value is critical. Here’s what you need to know.
Mold & Home Marketability
If you plan on selling your home and know your property has a mold issue, we highly recommend scheduling professional mold damage removal before listing. Why? Mold is a health and safety hazard, and state law requires that you disclose such issues to buyers.
But here’s where things get sticky: Disclosing a mold issue in a listing description will scare off most buyers. At the same time, failing to disclose could result in legal or financial consequences if the buyer discovers the problem after the sale.
Long story short? If you have a known mold issue, call us immediately. RenewPro will handle mold damage removal quickly and safely, ensuring your home is ready to sell.
Mold & Property Value
Mold issues can tank home values by 10-30%, depending on the severity. In fact, the Appraisal Journal estimates that 50% of buyers walk away after discovering mold during an inspection, and those who bravely press on to closing typically demand significant price reductions.
Types of Mold That Affect Value Most
Even seemingly insignificant mold patches can raise the alarm during an inspection. However, certain mold types (and the location in which you find them) can have an especially severe impact on your property value:
Visible Surface Growth
Notice black, green, or white patches on walls, ceilings, or floors? Even if it hasn't caused structural damage, expect prospective buyers to run the other direction. Visible mold suggests moisture problems that could affect the entire home—which means you need professional mold damage removal services ASAP.
Hidden Growth in Walls
Mold growing behind drywall, under floors, or in hidden spaces like attics and crawlspaces typically indicates long-term moisture issues. Hidden growth can significantly reduce property value as buyers fear the unknown—they can’t see the full extent of the damage, which either drives them away or means a serious price reduction.
Structural Damage
When mold deteriorates structural elements like floor joists or wall studs, the impact on property value multiplies. These situations require both remediation and repairs, replacing everything from drywall and flooring to subflooring and studs. The cost of structural repairs, combined with mold damage removal and remediation, can decimate property values.
Mold: The Health Risks
Mold isn’t just unsightly—it can also cause:
- Respiratory problems, including coughing, wheezing, and asthma flare-ups
- Allergic reactions like runny nose, itchy eyes, and skin rashes
- Severe symptoms in the elderly, children, and those with compromised immune systems, including:
- Headache
- Fatigue
- Dizziness
- Confusion
- Feber
- Muscle aches
- Joint pain
- Nausea
- And even death
How to Prevent Mold Growth
When it comes to mold, prevention is always preferred. The best way to keep mold at bay is to:
- Keep indoor humidity below 60%
- Always repair leaky pipes and faucets
- Turn on exhaust fans when cooking and showering
- Clean out your exterior gutters
- Make sure water drains away from your home
If you discover mold growth in your home, time is of the essence, so call a mold damage repair specialist at RenewPro immediately. But in the meantime, there are several steps you can take to mitigate damage:
- Remove wet materials—anything that absorbs moisture
- Dry out the area by mopping up excess water and using fans and dehumidifiers to increase airflow while lowering moisture levels
- If outdoor temperature allows, open windows to create a cross breeze
